ABSTRACT

Introducción:los schwannomas, también llamados neurilemomas o neurinomas, son tumores de origen neuroectodérmico, encapsulados y benignos, que generalmente aparecen como una masa laterocervical asintomática de crecimiento lento. Son pocos frecuentes en el área de cabeza y cuello.Caso clínico:mujer de 39 años con una historia de un año de evolución de una masa cervical derecha de crecimiento lento, pulsátil, dolorosa y móvil en el lado derecho del cuello. La imagen de la angiotomografía computarizada preoperatoria demostró que la masa involucraba la bifurcación carotídea, compatible con un paraganglioma carotídeo. La disección cuidadosa a través de una cervicotomía longitudinal mostró que la masa surgía de un único fascículo del nervio vago. La masa se envió a anatomía patológica con el resultado de schwannoma. En el posoperatorio la paciente presentó una función sensorial y motora del vago normal, con un leve síndrome de Horner.Discusión:los tumores nerviosos del cuello surgen a partir de grandes troncos nerviosos, los IX, X, XI y XII pares craneales, el simpático cervical, el plexo cervical y el plexo braquial. El nervio vago es un lugar infrecuente de aparición, con muy pocos casos reportados. Son lesiones de diagnóstico preoperatorio difícil, cuyo tratamiento de elección es la exéresis quirúrgica; en ocasiones, es difícil conservar el nervio de origen.(AU)


Introduction:schwannomas, neurilemomas or neurinomas, are benign, encapsulated, neuroectodermal tumors that generally appear as a slow-growing, asymptomatic laterocervical mass. They are rare in the head and neck area.Clinical case:a 39-year-old woman with a one-year history of a slowly enlarging, pulsatile, painful and movable right cervical mass on the right side of the neck. Preoperative computed angiotomography image demonstrated that the mass involved the carotid bifurcation compatible with a carotid paraganglioma. Careful dissection through a longitudinal cervicotomy, showed that the mass arose from a single fascicle of the vagus nerve. The mass was sent to the pathologists and found to be a schwannoma. The patient had normal vagus sensory and motor function postoperatively, with a slight Horner syndrome.Discussion:nerve tumors of the neck arise from large nerve trunks, the IX, X, XI, and XII cranial nerves, the cervical sympathetic, the cervical plexus, and the brachial plexus. The vagus nerve is an infrequent place of appearance with very few reported cases. They are difficult preoperative diagnosis lesions; whose treatment of choice is surgical excision; sometimes it is difficult to preserve the nerve of origin.(AU)

ABSTRACT

Introducción: los aneurismas micóticos son una entidad grave y poco frecuente, cuyo tratamiento quirúrgico se ha basado históricamente en la resección del tejido infectado y en la reconstrucción arterial. En los últimos años, la importancia del uso de técnicas de reparación endovascular ha ido en aumento. Caso clínico: se presenta el caso de una mujer de 84 años con un aneurisma micótico de la aorta visceral tratado mediante un abordaje híbrido. Se revascularizan las arterias mesentérica superior y hepática y, posteriormente, se coloca una endoprótesis de aorta. Discusión: el empleo de dispositivos endovasculares para la reparación de los aneurismas micóticos genera controversia debido a que no se elimina el tejido infectado. Sin embargo, existen publicaciones que avalan su uso, ya que permiten el tratamiento, principalmente, de pacientes de alto riesgo quirúrgico sin aumentar el número de complicaciones.(AU)


Introduction: mycotic aneurysms are a serious and rare entity, whose surgical treatment has historically been based on resection of infected tissue and arterial reconstruction. In recent years, the importance of using endovascular repair techniques has increased. Case report: an 84-year-old woman with a mycotic aneurysm of the visceral aorta is presented, treated by a hybrid approach, revascularizing the superior mesenteric and hepatic arteries, and the placement of an aortic stent. Discussion: the use of endovascular devices for the repair of mycotic aneurysms generates controversy due to the maintenance of the infected tissue. However, there are publications that support its use since they allow the treatment mainly of patients at high surgical risk not increasing the rate of complications.(AU)

ABSTRACT

Fundamento y objetivo: Describir las características de los tumores carcinoides bronquiales diagnosticados en nuestro hospital en los últimos 20 años, y determinar su evolución y supervivencia tras tratamiento quirúrgico. Pacientes y método: Revisión retrospectiva de las historias clínicas de los pacientes diagnosticados y tratados de tumor carcinoide bronquial en nuestro centro entre enero de 1992 y junio de 2012. Resultados: Se analizaron 60 pacientes, de los cuales 52 (87%) tenían carcinoide típico y 8 (13%) carcinoide atípico. La edad media (DE) de presentación fue de 60 (14,4) años. No se encontró ninguna relación con el consumo de tabaco. El 22% de los pacientes estaban asintomáticos, siendo un hallazgo radiológico casual. Tres pacientes presentaron síndrome carcinoide y uno síndrome de Cushing. La localización fue de predominio derecho y el tamaño medio de la lesión fue entre 2,1 y 5 cm. El 9% tenía afectación linfática, predominantemente carcinoides atípicos. La supervivencia global a los 3, 5 y 10 años fue del 94, 86 y 82%, respectivamente. La supervivencia a los 5 años fue del 90% para los típicos y del 86% para los atípicos y la supervivencia a los 10 años fue del 85% para los típicos y del 57% para los atípicos. Conclusiones: Los tumores carcinoides son tumores malignos por su capacidad para metastatizar. En nuestro estudio, el tipo histológico y la estadificación fueron factores pronósticos (AU)


Background and objective: To describe the casuistry of bronchial carcinoid tumor in the last 20 years in our hospital and determine survival after surgical treatment. Patients and method: We retrospectively reviewed the medical records from January 1992 to June 2012 of patients diagnosed with carcinoid tumor by the pulmonary service. Results: Fifty-two patients (87%) had typical carcinoid and 8 (13%) atypical carcinoid. The mean age at diagnosis was 60 years (SD: 14.4). There was no relationship between consumption of tobacco and carcinoid tumor. Twenty-two per cent were asymptomatic radiographic finding (incidental finding) Three patients showed carcinoid syndrome and one patient had Cushing syndrome. There was a right dominance and the mean lesion size was between 2.1 and 5 cm. Nine per cent had lymph node involvement, predominantly in atypical carcinoid. Overall survival at 3.5 and 10 years was 94%, 86% and 82%. Survival at 5 years was 90% for typical and 86% for atypical and survival at 10 years was 85% for typical and 57% for atypical carcinoids. Conclusion: Carcinoid tumors are malignant tumors by their ability to metastasize. In our study, both histological type and staging were predictors of survival (AU)

ABSTRACT

Introducción. Estudios multicéntricos recientes sugieren un dudoso beneficio de la endarterectomía carotídea (EC) en pacientes con pseudooclusión carotídea (POC). Objetivo. Evaluar el resultado clínico y hemodinámico de la EC en las POC sintomáticas. Pacientes y métodos. Entre 1999 y 2005 se intervinieron 13 pacientes con POC interna (3,96% de la cirugía carotídea) sintomáticas: siete con infarto cerebral (53,8%), tres con accidente isquémico transitorio (23,1%), dos con amaurosis fugaz (15,4%) y uno con síncopes de repetición (7,7%). En todos se realizó eco-Doppler y angiografía. Criterios diagnósticos del eco-Doppler: oclusión origen carótida interna, flujo en goteo o señal distal amortiguada. Criterios diagnósticos de la angiografía: obstrucción origen carótida interna con relleno filiforme distal. Se indicó la revascularización quirúrgica en todos ellos. Resultados. En 12 pacientes se pudo revascularizar la carótida interna (92,3%) y en uno se hizo su ligadura (7,7%). Técnica de revascularización: 11 EC y un bypass a carótida interna distal. Morbimortalidad quirúrgica del 0%. Control clínico: 3-69 meses (media: 31,6 meses) mediante eco-Doppler de troncos supraaórticos y transcraneal, encontrándose todos vivos, asintomáticos y con permeabilidad de la carótida interna. La reserva hemodinámica homolateral postoperatoria se ha encontrado normalizada en la mayoría de los pacientes. Conclusiones. Se considera indicada la intervención quirúrgica en casos sintomáticos de POC, ya que logra la repermeabilización de la carótida y la normalización de la reserva hemodinámica en un alto porcentaje, previniendo además la aparición de nueva sintomatología a largo plazo


Introduction. Recent multicentre studies suggest dubious benefits for carotid endarterectomy (CE) in patients with pseudo-occlusion of the carotid artery (POC). Aim. To evaluate the clinical and haemodynamic outcomes of CE in cases of symptomatic POC. Patients and methods. Between 1999 and 2005 interventions were carried out on 13 patients with symptomatic pseudo-occlusion of the internal carotid artery (3.96% of the carotid surgery conducted): seven with cerebral infarction (53.8%), three with transient ischemic attack (23.1%), two with amaurosis fugax (15.4%) and one with recurring syncopes (7.7%). Doppler ultrasonography and angiography recordings were performed in all cases. Diagnostic criteria for Doppler ultrasonography were occlusion with its origin in the internal carotid artery, a drip flow or attenuated distal signals. Diagnostic criteria for angiography were occlusion with its origin in the internal carotid artery with filiform distal filling. Surgical revascularisation was indicated in all cases. Results. The internal carotid artery was revascularised in 12 patients (92.3%) and ligation was performed in one of them (7.7%). Revascularisation technique: 11 CE and one distal internal carotid artery bypass. Surgical morbidity and mortality rates of 0%. Clinical monitoring: 3-69 months (mean: 31.6 months) using transcranial and supra-aortic trunk Doppler ultrasonography; all patients were alive, asymptomatic and with patency of the internal carotid artery. The post-operative homolateral haemodynamic reserve was found to be at normal levels in most of the patients. Conclusions. Surgical intervention is considered to be indicated in symptomatic cases of POC, as it achieves repatency of the carotid artery and normalises the haemodynamic reserve in a high percentage of cases; it also prevents the appearance of new symptoms in the long term
