However, the more proximal the lesion, the more likely abnormal sprouting will occur. Clinical features and diagnosis Initial signs and symptoms Sensation and motor activity can be tested in older chil dren and adults. The striking finding in neonates is a fail 3 ure to move the arm, which hangs limply with the elbow extended and does not even move when the typical infant reflexes are elicited. If the lower cervical roots are also involved the grip movement of the hand is absent. In the more common upper plexus lesion (Erb-Duchenne) the roots of C 5 and C 6 are affected. Examination of motor function reveals the absence of abduction and external rotation at the shoulder, elbow flexion and, to some ex tent, elbow extension, supination and wrist extension. Wrist arthrodesis in severe athetosis impairment that does occur is located on the outer aspect of the upper arm and the radial side of the forearm. The small surgical procedures on the upper extremities should be hand muscles show no activity and the ulnar fingers, in indicated more liberally, subject to the requirement that, particular, adopt a claw-like posture. But the long finger as with all functional procedures, reliable and adequate flexors and wrist flexors may also be weak or inactive. A Horner syndrome (ptosis, myosis, enophthal mos) may also be present, indicating the involvement of 3. Besides these Plexus palsy two typical clinical pictures, a total arm plexus palsy or other forms of plexus palsies (involvement of C 7 or fas > Definition cicular palsies) may also be present. A plexus palsy refers to a nerve lesion between the point With the aid of an electromyogram, a distinction can at which the spinal roots leave the cord and the point be made between a complete and incomplete paralysis and where they divide to form the peripheral nerves. If deficient movement is present in the upper limb, Etiology and pathogenesis the differential diagnosis must first rule out other injuries Plexus palsies of the upper extremity can occur at birth (fractures of the humerus or clavicle or infections in the as a result of manipulations. Older children and adults can Late sequelae suffer plexus lesions of the upper, or more rarely the lower, Pareses due to birth trauma are typically followed by the extremity in traffic accidents (particularly motorcycle ac development of a muscular dyskinesia at shoulder level, cidents) [15]. No basic distinction is made between plexus where abduction occurs rather between the scapula and lesions in the neonate and the adult [17]. At the same time, not completely severed or torn, the axon will regrow from flexor activity is triggered in the arm, leading to flexion 491 3 3. They also involve the risk of shoulder sublux by altered motor neuron activity, abnormal sprouting or ations, particularly if there are deficits in the muscles that by the abnormal development of the maturing nervous stabilize the shoulder. This procedure is indicated if there are no signs of tracted, usually in a position of internal rotation/adduc a recovery of motor or sensory function by the end of 3 tion. The surgical options include neurolysis, direct opment of bone deformities as a result of the modified suturing or a nerve interposition, and neurotization. The glenoid flattens out and rolysis is indicated if pain is present or, to a lesser extent, becomes broader, while the physiological retrotorsion at in order to improve function. This leads to posterior sub severed, nerve suturing, possibly with the interposition of luxation. The prognosis is better for as a result of hyperactivity of the biceps and brachialis the upper roots than the lower roots, and this also applies muscles and the use of the elbow in a flexion position. Neurotization may be indicated olecranon and coronoid process become enlarged and ad in the event of root avulsions. Lower palsies mainly of elbow function with this method is good (> 50% of affect the hand muscles only. Treatment and prognosis Any subsequent corrective operation must be preceded the prognosis for an upper plexus palsy is better than that by a careful investigation of the functional disorders and for a lower palsy. Overall, over 90% of cases of postpartal deformities and the resulting impairment to the patient. Troublesome eters include the effect of substantial force, complete pal functional deficits can be improved by muscle transfer sies, additional injuries and pain. The latter is indicative procedures, and existing contractures must be eliminated of a root avulsion. The sensory functions recover much beforehand or at the same time with a muscle transfer better than the motor functions. Conservative treatment External rotation and abduction of the arm can be In view of the inherently good prognosis, the primary improved by transfer of the levator scapulae to the supra goal of treatment must be to prevent the onset of second spinatus and relocation of the teres major, with or without ary deformities as these will restrict the function of the the latissimus dorsi, to the infraspinatus muscle. Training of the trapezoid can also be transferred to improve the shoulder existing and newly innervated muscles is also helpful. In addition, there may be posterior or anterior In order to promote the best possible healing, the arm is subluxation or dislocation of the humeral head. From this position, otomy of the proximal humerus in the direction required the muscles are stretched and the existing muscles acti to center the joint [23]. The method according to Vojta is also be used as a replacement for the deltoid [17]. If severe often used for these palsies, but this should probably aim and troublesome instabilities are present, an arthrodesis at strengthening the existing muscles rather than promot of the shoulder may be indicated. The extent to which such stimulation is important for any functional use of the arm. The latis treatments actually produce a positive effect on axonal simus dorsi can also be used to improve elbow flexion. Orthoses and braces can be used, at best, as braces if A precondition for this procedure is a free pronation/su no recovery occurs in the long term and the contracture pination movement. A posterior radial head A curative procedure is suturing of the damaged nerve, dislocation can also occur, and this can be corrected by possibly with an interposed graft. The prognosis is bet radial shortening (in younger children) or a radial head ter, the more distal the lesion, the smaller the damaged resection (in older children). Thumb opposition can be section, the younger the patient and the shorter the pe restored by transferring the flexor digitorum superficialis riod that elapses until treatment. Palliative surgical procedures include muscle transfers and stabilizing measures such as arthrodeses or tenodeses. Etiology and pathogenesis Before any operation the functional deficits and the degree Peripheral nerves are injured in accidents, as the result of of handicap must be clarified and the expectations dis deliberate harm or iatrogenically following their acciden cussed with the patient (Chapter 3. If radial nerve pal tal severing at operation or traction exerted, for example, sy is present, wrist extension can be improved by transfer during the course of corrective axial and lengthening ring the pronator teres muscle to the long and short radial procedures on the extremities. In a median nerve palsy the deficit interferes sation and motor function in the area supplied by that with finger flexion and thumb opposition. The signs and symptoms in typical areas enable pronation of the thumb can be restored by transferring the the damage to be assigned anatomically to the individual extensor indicis muscle, and adduction by relocation of the nerves (Chapter 2. The sensory impairment can be extensor carpi radialis brevis muscle in combination with a present in the form of anesthesia, hypoesthesia, paresthe thumb metacarpophalangeal joint arthrodesis. A distinction lis, although this will result in a loss of power in respect must be made between prognostically favorable incom of fist closure. The pinch grip must be restored with ad plete paralyses and complete failures with anesthesia and ditional measures such as a metacarpophalangeal joint complete paresis. A spontaneous remission can generally arthrodesis of the index finger and transfer of the extensor be expected for incomplete lesions. In any muscle paralysis, however, only over time will it become apparent transfer procedure, however, the surgeon must weigh the whether function will recover or whether the deficit will loss resulting from the removal of the muscle against the persist unchanged. The goal of treatment is to give the patient as much Treatment and prognosis independence as possible. Although the range of motion Conservative treatment in the joints can often not be increased, it can be relocated the orthopaedic treatment is primarily aimed at pre so that the use of the extremity can be improved. At the serving mobility and avoiding contractures so that the same time it may prove necessary to treat both upper muscles can resume their function under the optimal limbs asymmetrically in order to bring one side more in conditions. The main focus of conservative measures is on extension and the other more in flexion. This can help exercise-based treatments in the context of occupational restore the functions needed for eating and personal hy therapy and/or physiotherapy. Contractures and muscle weakness at the shoulder and strengthening exercises, training is provided in the are often present concurrently. Braces can be helpful however, tend to be present only in cases of fixed internal for avoiding contractures. Moreover, functional orthoses rotation, because the arm can no longer be controlled in a can make up for lost muscle functions. In older children or in cases of more pronounced defor Contractures at the elbow can progress in a variety of mity, reconstructive procedures on the skin and corrective ways. Whereas some patients respond well to conserva osteotomies on the metacarpals may also be required. For tive measures, the deformity becomes progressively worse pronounced contractures, the necessary lengthening of the in others, ultimately resulting, for example, in a flexion muscles can be achieved by bone shortening, either by a contracture at the elbow with movement around the right shortening osteotomy of the forearm or by resection of the angle, but with sufficient power remaining in the biceps proximal row of carpal bones. On the other hand, the elbow may stiffen Post-polio syndrome in an extended position, which can significantly interfere On the upper extremity, the deltoid is the muscle most with everyday functioning. In these cases, lengthening or commonly affected in this disorder, although the muscles transfer of the triceps brachii muscle, possibly combined of the rotator cuff may also be paretic and possibly lead with a flexor reconstruction, may be indicated. Troublesome disloca Often a severe flexion contracture at the wrist will tions require an arthrodesis to stabilize the joint. At the already be present at birth, and sometimes fingers and elbow, both flexors and extensors can show weaknesses thumb are also affected. Measures to correct this deformity while, at hand level, thumb opposition in particular is must be initiated as soon as possible, with stretching exer impaired. At a later stage, the wrist instability, and particularly the lack of dorsal flexion, will present a major References problem.

Medical disorders and anaesthetic problems H Haemoglobinopathies (sickle cell Sickle cell disease disease) (see also Thalassaemia) A genetic abnormality of haemoglobin synthesis Normal haemoglobin (HbA) consists of a involving the substitution of valine for glutamic colourless protein, globin, which is made up acid at the sixth amino acid position in the beta from two alpha and two beta polypeptide chains, chain of the globin molecule. The haem radical is a frequently in blacks of African origin and in porphyrin structure, at the centre of which is a some Mediterranean races. Haemoglobinopathies associated with cell membrane is deformed by these molecular unstable haemoglobin. The process is complex and the precise mechanism of vaso occlusion is not known (Steinberg 1999). Sickle cell disease is associated with small Cooperative Study of Sickle Cell Disease and vessel occlusion and episodes of infarction in the Preoperative Transfusion in Sickle Cell affected organs. Reduced oxygen tension and al 1994), morbidity and mortality associated with acidosis cause sickling of red cells. The surgery and anaesthesia (Koshy et al 1995), and a 219 increased viscosity encourages stasis and trial of preoperative aggressive transfusion versus sludging, which in turn produces occlusion, conservative transfusion (Vichinksy et al 1995, ischaemia, and infarction.

Desde un punto de vista clinico se clasifican en malformaciones de alto y bajo flujo treatment 001 - b order cabgolin online from canada. Las que tienen componente arterial se consideran de alto flujo y las que carecen de dicho componente son consideradas de bajo flujo medicine x ed cheap cabgolin 0.5mg with amex. Nevus anemico Malformacion poco comun de tipo funcional, ya que anatomicamente los vasos son normales. Es debida a una reactividad aumentada de los vasos a las catecolaminas, que provoca una vasoconstriccion permanente. Clinicamente consiste en una macula blanquecina de margenes irregulares y frecuentemente acompanada de lesiones satelites. Es mas frecuente en el sexo femenino y puede aparecer en cualquier localizacion, aunque la parte superior del tronco es la mas comun. Al friccionar energicamente la lesion, esta permanece blanca y la zona periferica se enrojece (a diferencia de los nevus acromicos, que si se enrojecen al friccionarlos). El examen con luz de Wood no acentua la lesion, al contrario de lo que ocurre con las lesiones debidas a falta de melanina. Cutis marmorata telangiectasica congenita Esta malformacion se caracteriza clinicamente por maculas de color rojo-violaceo que se disponen formando un reticulado que recuerda el veteado del marmol, de ahi su nombre 12-4. Nevus flameo o mancha en vino de Oporto El nevus flameo, llamado tambien angioma plano (nombre inadecuado ya que se trata de una malformacion), se presenta en forma de maculas de color rosado que pueden aparecer en cualquier parte del cuerpo, aunque la cara es la localizacion mas frecuente 12-5. Las manchas, con la edad, toman un color rojo mas intenso y terminan de color violaceo. Cuando afecta a la cara hay que descartar un glaucoma, el 10% de los nevus flameos faciales pueden presentar esta complicacion, especialmente frecuente si se afecta el territorio de las ramas oftalmica y maxilar del trigemino. Otra posible asociacion es el sindrome de Klippel-Trenaunay 12-6, que consiste en el aumento de tamano de un miembro (con o sin hipertrofia osea). El sindrome de Sturge-Weber consiste en la presencia de un nevus flameo facial generalmente extenso que afecta la frente, zona periocular y area maxilar. Aunque la lesion suele ser unilateral, un 50% pueden presentar afectacion bilateral de la cara 12-7. El sindrome tambien presenta afectacion vascular leptomeningea y en un 30-60% afectacion ocular. Las manifestaciones neurologicas mas comunes son epilepsia y retraso mental, aunque tambien pueden presentarse hemiplejia, hemianopsia y defectos sensoriales. El tratamiento de la mancha en vino de Oporto se realiza con laseres vasculares como el de colorante pulsado (Candela) o el neodimio-yag (Vascu-light), o mediante luz intensa pulsada (Photoderm). Los resultados son mejores si el tratamiento se realiza en la infancia que si se espera a la edad adulta. Mancha salmon Se trata de una lesion macular de color rojo claro (salmon) que se localiza en los parpados, region glabelar y nuca. Es muy frecuente, afectando al 25-40% de los recien nacidos y tiende a desaparecer durante los primeros anos de vida. La mancha salmon localizada en la nuca (conocida coloquialmente como picadura de la ciguena), suele ser mas persistente y a menudo se mantiene durante la edad adulta. Marcas vasculares hiperqueratosicas Patologia poco frecuente a la que tambien se ha denominado hemangioma verrucoso, y aun se emplea este termino, pero es inadecuado ya que se trata de una verdadera malformacion y no de un hemangioma (neoplasia). Se trata de placas de color rojo purpura o azulado, que crecen lentamente y van desarrollando una franca hiperqueratosis en su superficie que les dan un aspecto verrucoso 12-8. El tratamiento es dificil y la unica opcion es la cirugia cuando las lesiones no son de gran tamano. Malformaciones venosas Las malformaciones venosas han sido a menudo mal llamadas hemangiomas cavernosos. Estan siempre presentes en el nacimiento y aumentan de tamano proporcionalmente al crecimiento del nino. No involucionan y, por tanto, siempre van a estar presentes a lo largo de la vida del paciente. Tambien se pueden encontrar flebolitos calcificados en el interior de las mismas y pueden ocurrir episodios de tromboflebitis en las lesiones o en su proximidad. Suelen ser asintomaticas, pero pueden provocar defectos esteticos y compresion de estructuras vecinas. Las malformaciones venosas pueden asociarse a otras anomalias y formar parte de sindromes mas complejos 12-10. Puede ser heredado de forma autonomica dominante, aunque existen casos esporadicos. Se trata de nodulos azulados facilmente compresibles, generalmente de pequeno tamano y que recuerdan a la presion a la tetina de un chupete. En la piel suelen existir pocas lesiones, pero en el tracto intestinal son a menudo multiples y es frecuente el sangrado espontaneo, lo que provoca melenas y anemia. Aunque es menos frecuente, tambien pueden existir estas malformaciones venosas en otros organos como pulmon, corazon, higado, cerebro. Si la clinica de melenas y anemia es recurrente estaria indicada la reseccion del segmento intestinal afecto. Sindrome de Maffucci Se caracteriza por malformaciones venosas, encondromatosis asimetrica difusa y deformidades esqueleticas. Al nacimiento no suelen ser visibles las malformaciones, poniendose de manifiesto las lesiones en la primera infancia. Se trata de nodulos o tumores de color azulado que suelen afectar mas a las extremidades. A esto se asocian tumores oseos de los huesos largos, manos y pies, que corresponden a encondromas, y pueden provocar importantes deformidades 12-11. En un 15% de los pacientes estos tumores pueden degenerar y desarrollar un condrosarcoma. Malformaciones linfaticas La clasificacion de los distintos tipos de malformaciones linfaticas se detalla en 12-12. Malformaciones linfaticas microquisticas o superficiales Estas malformaciones, mal llamadas linfangioma circunscrito (ya que no se trata de un tumor), suelen presentarse en el nacimiento o primera infancia. Pueden localizarse en cualquier area anatomica, pero las axilas, zonas proximales de las extremidades y la lengua son los sitios de eleccion. Clinicamente, se caracterizan por multiples lesiones de aspecto similar a vesiculas agrupadas en placas, a modo de huevos de rana. En ocasiones presentan un componente de vasos sanguineos asociado que hace que algunas lesiones tengan color rojo 12-13. El tratamiento es quirurgico, pero son frecuentes las recidivas ya que es dificil establecer los limites de la lesion y a veces existe un componente profundo de la malformacion que favorece las recurrencias. Suelen ser asintomaticas, pero producen importantes deformidades esteticas 12-14, y ocasionalmente comprometen la respiracion o la alimentacion, al comprimir la via aereodigestiva alta. No suelen estar presentes al nacimiento y si lo hacen (40%) es en forma de una mancha eritematosa de pequeno tamano. En las primeras semanas de vida crecen rapidamente para despues en la mayoria de los casos involucionar. Existen distintos tipos de hemangiomas que se resenan en 12-15, pero hablaremos fundamentalmente de los mas frecuentes en la infancia (hemangioma infantil) y de aquellos que puedan provocar problemas o complicaciones en el nino (angioma en penacho y hemangioendotelioma kaposiforme). Historia natural Los hemangiomas infantiles tienen una primera fase proliferativa en la que crecen y que acontece en el primer ano de vida y otra fase involutiva que dura varios anos. En el 40% de los casos el hemangioma esta presente al nacimiento y puede evidenciarse algun signo del mismo, en forma de macula telangiectasica, lesion equimotica o macula equimotica con halo palido. La mayoria de los casos inician su fase de crecimiento en las primeras semanas de vida, aunque algunos hemangiomas mas profundos pueden no detectarse hasta pasados varios meses. Esta fase de crecimiento rapido puede ser mas intensa durante los primeros 3 a 6 meses y la mayoria de estos tumores terminan su crecimiento entre los 9 y 12 meses de edad. Un pequeno porcentaje de hemangiomas apenas sufre cambios desde el nacimiento y otra pequena minoria continuaran creciendo durante mas de un ano. La fase involutiva se produce a partir del primer ano de vida y el hemangioma sustituye el componente vascular por tejido fibroadiposo, por lo que pierde en parte su color rojo, aparecen areas o bandas blanquecinas y se hace mas blando. La involucion completa se observa con una frecuencia aproximada de un 10% por ano, por lo que un 50% involuciona a los 5 anos, un 70% a los 7 y un 90% a los 9 anos. Al involucionar pueden quedar secuelas, a veces minimas como telangiectasias o piel atrofica, y en ocasiones cambios mas significativos como piel redundante con residuos fibroadiposos y cicatrices especialmente si el angioma se ulcero. A medida que involucionan, las luces vasculares se dilatan, las celulas endoteliales se aplanan y se deposita tejido fibroso, dando al hemangioma una arquitectura lobular. Clinica El aspecto clinico de los hemangiomas varia dependiendo de la localizacion del tumor, de ahi que se clasifiquen en hemangiomas superficiales, profundos y mixtos. Los superficiales asientan en la dermis superficial y son de color rojo brillante, por eso se las llama hemangiomas en fresa 12-16. Los hemangiomas profundos se desarrollan en la dermis reticular y tejido celular subcutaneo, y se manifiestan como masas blandas de tonalidad azulada o del color de la piel 12-17. Los hemangiomas infantiles pueden localizarse en cualquier zona del cuerpo, dandose con mas frecuencia (60%) en cabeza y cuello. Desde el punto de vista del area que afectan tambien se clasifican en focales, cuando afectan a una zona pequena, o en segmentarios (similares a placas) cuando afectan a un segmento anatomico mas amplio 12-18. Estos ultimos suelen asociarse con mayor frecuencia a complicaciones, como veremos mas adelante. Complicaciones El 10% de los hemangiomas presentan complicaciones que pueden ser debidas al propio tumor o bien derivadas de su localizacion. Habitualmente se produce durante la fase proliferativa y suele ocurrir en hemangiomas situados en zonas de friccion o maceracion, como la boca y el area anogenital. Las ulceraciones son dolorosas y por eso si se localizan en los labios pueden dificultar la alimentacion y en la zona anogenital la defecacion o miccion. Se caracterizan por la presencia de un exudado purulento y aumento del calor y el dolor. Se deben realizar cultivos del exudado y tratar la infeccion con antibioticos por via topica y sistemica. Suele ser un sangrado leve o moderado en angiomas ulcerados y que se resuelve facilmente con compresion directa. Mas raro es una hemorragia profusa que puede ocurrir por un fenomeno de Kasabach-Merritt (coagulopatia de consumo), lo cual es muy raro en hemangiomas infantiles clasicos, siendo mas comun en hemangioendoteliomas kaposiformes y angiomas en penacho. Estas secuelas pueden ocurrir con la propia involucion del tumor y son mas frecuentes en aquellos de gran tamano. Complicaciones debidas a la localizacion del hemangioma Como comentabamos los hemangiomas segmentarios de ciertas localizaciones pueden dar lugar a ciertas complicaciones 12-21, que describimos a continuacion. Esta presentacion requiere un control y estudio muy estricto ya que pueden provocar importantes problemas. La complicacion mas importante es la ambliopia o vision reducida del ojo afecto, debida a la deprivacion de estimulo visual en los hemangiomas que por su tamano obstruyen el eje visual. Otra complicacion frecuente es la deformacion de la cornea inducida por la presion local directa del tumor, lo cual provoca astigmatismo. Estos tumores pueden provocar obstruccion de la via aerea superior y provocar sintomas de tos, disfonia e insuficiencia respiratoria, por lo que precisan de un estudio otorrinolaringologico detallado. La presencia de un hemangioma en region lumbosacra debe alertar sobre la posibilidad de un disrafismo espinal oculto o de alteraciones genitourinarias. El termino hemangiomatosis se utiliza para describir la presencia de hemangiomas generalizados de pequeno tamano, pudiendo existir entre pocos elementos y centenares. Puede existir solo afectacion cutanea, utilizandose el termino hemangiomatosis neonatal benigna, pero puede haber afectacion visceral, especialmente afectacion hepatica, en este caso se utiliza el termino de hemangiomatosis neonatal diseminada. La afectacion hepatica puede representar un mal pronostico y estos casos deben ser tratados con corticoides sistemicos. Tratamiento La mayoria de los hemangiomas no requieren tratamiento, ya que involucionan espontaneamente. No existen unos criterios protocolizados de tratamiento, debiendose valorar cada caso individualmente. Los corticoides sistemicos son la primera herramienta en el tratamiento de los hemangiomas. La dosis recomendada es generalmente de entre 2 y 3 mg/kg de prednisona en una dosis unica matinal. El tratamiento se realiza de 4 a 6 semanas y luego se reduce gradualmente la dosificacion. Se deben utilizar en la fase proliferativa, que es cuando se consiguen mejores resultados. Los efectos secundarios mas frecuentes son fiebre y sindrome seudogripal que pueden tratarse con paracetamol. Por ello, hoy dia se recomienda usar este farmaco solo en casos de angiomas con complicaciones graves que no han respondido a esteroides. Se emplea en hemangiomas de gran tamano y en casos asociados a fenomeno de Kasabach-Merritt. La dosis habitual es de 0,05 mg/kg en ninos menores de 10 kg o 1,5 mg/kg en ninos con peso superior a 10 kg, administrados via intravenosa de forma semanal. Esta indicado en las telangiectasias residuales que pueden permanecer tras la involucion. Tambien se ha utilizado en los hemangiomas ulcerados y, aunque es un tema controvertido, algunos autores lo utilizan en angiomas de pequeno grosor durante la fase proliferativa. Puede estar indicada en hemangiomas de los parpados que no responden a tratamiento medico. Se emplearia en hemangiomas hepaticos con fistulas arteriovenosas, que suelen provocar insuficiencia cardiaca. Tambien existen casos de aparicion en el nacimiento y en la edad adulta, Suele localizarse en el cuello, hombros y zona alta del tronco, aunque puede aparecer en otras zonas del cuerpo. El aspecto clinico es muy variable, puede presentarse en forma de macula, placa o nodulo 12-24.
