RESUMO

Introducción. Los aneurismas, verdaderos o falsos, de la arteria glútea superior e inferior son muy raros, y la mayoría se relaciona con traumatismos pélvicos o heridas penetrantes en la región glútea. Caso clínico. Varón de 70 años con una fístula persistente en la región glútea derecha de seis meses de evolución tras el drenaje de un absceso glúteo. La resonancia magnética informa de la existencia de un aneurisma de la arteria ilíaca interna derecha. Con este diagnóstico, es remitido a nuestro Servicio de Angiología y Cirugía Vascular donde, mediante una angiotomografía computarizada (angio-TC), se objetiva la presencia de un pseudoaneurisma dependiente de la arteria glútea superior derecha. Durante el estudio arteriográfico se decide realizar un tratamiento endovascular con embolización intraarterial selectiva de la arteria glútea superior, para conseguir la trombosis-exclusión del aneurisma. En la angio-TC de control de los tres meses se observa la trombosis del pseudoaneurisma y en la angio-TC de control a los nueve meses se constata una reducción de su tamaño. Conclusión. Se discute la incidencia, las formas de presentación y la estrategia quirúrgica de esta patología infrecuente y se revisa la bibliografía actual


Introduction. Aneurysms, either true or false, of the superior and inferior gluteal artery are very rare and most of the cases that are seen are related to traumatic injury to the pelvis or stab wounds in the gluteal region. Case report. A 70-year-old male who had had a persistent fistula in the right-hand gluteal region for six months following the drainage of a gluteal abscess. Magnetic resonance imaging showed the existence of an aneurysm in the right internal iliac artery. With this diagnosis, the patient was referred to our Angiology and Vascular Surgery Service, where a pseudoaneurysm was detected in the right superior gluteal artery by means of computerised tomographic angiography (CT-angiography). During the arteriographic study it was decided that endovascular treatment with selective intraarterial embolisation of the superior gluteal artery should be carried out in order to achieve thrombosis-exclusion of the aneurysm. Thrombosis of the pseudoaneurysm was observed in the follow-up CT-angiography carried out at three months and the follow-up CT-angiography study performed at nine months showed that it had got smaller. Conclusions. The incidence, presenting symptoms and surgical strategy of this infrequent pathology are discussed and the current literature on the subject is reviewed

RESUMO

La causa más frecuente de varices es el reflujo en el confluente safenofemoral, pero no es la única. La correcta identificación preoperatoria de los puntos de fuga (PF) parece básica a la hora de plantear una correcta indicación quirúrgica. Objetivo. Identificar los diferentes PF en los pacientes enviados por varices primarias no evolucionadas. Pacientes y métodos. Durante el año 2003 se realizó un eco-Doppler (ED) venoso a todos los pacientes incluidos en el estudio. La exploración se llevó a cabo en bipedestación, sobre la extremidad de mayor relevancia clínica, mediante las maniobras de compresión-relajación, Valsalva y Paraná. Los resultados se almacenaron en una base de datos informática y en una cartografía hemodinámica. Resultados. Se objetivó reflujo safeno en 95 pacientes y no safeno en 5. El flujo retrógrado afectó a la safena interna en 87 pacientes y en 12 a la externa. Sólo el 71% de los flujos retrógrados de la interna fueron ostiales puros, presentando 30 pacientes un PF diferente a los cayados de safena, ya fuese aislado o asociado a éste. Conclusión. En un porcentaje no despreciable de pacientes el PF no se sitúa en los cayados safenianos, o existe más de uno, por lo que la cirugía no guiada por ED podría conllevar un inadecuado tratamiento y contribuir a la elevación de la tasa de recidivas


The origin of varicose veins most often lies in the backflow that occurs in the saphenofemoral junction, but it is not the only cause. Correct preoperative identification of the leakage points (LP) is essential when it comes to designing the right surgical approach. AIMS. The aim of this study was to identify the different LP in patients referred because of undeveloped primary varicose veins. PATIENTS AND METHODS. Throughout the year 2003 all the patients included in the study were submitted to venous Doppler ultrasound recording (DU). The examination (of the clinically more affected limb) was performed while patients were standing, using the compression-relaxation, Valsalva and Paraná manoeuvres. Results were saved in a computer database and in a blood map. RESULTS. Saphenous backflow was observed in 95 patients and in 5 of them it was non-saphenous. Backflow affected the great saphenous vein in 87 patients and in 12 of them it involved the small saphenous vein. Only 71% of the backflows in the great saphenous vein were purely ostial, and 30 patients presented an LP other than the saphenous arches, some being isolated while others were associated to it. CONCLUSIONS. In a fairly important number of patients, the LP is not situated in the saphenous arches, or there are more than one, and therefore surgery that is not guided by DU could lead to unsuitable treatment and contribute to an increase in the rates of relapses
