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 clínicoVarón 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 Angiologíay Cirugía Vascular donde, mediante una angiotomografía com-putarizada (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 delpseudoaneurismay en la angio-TC de control a los nueve meses se constata una reducción de su tamaño.
ConclusiónSe discute la incidencia, las formas de presentación y la estrategia quirúrgica de esta patología infrecuente y se revisa la bibliografía actual.
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 reportA 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 intra-arterial 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.
ConclusionsThe incidence, presenting symptoms and surgical strategy of this infrequent pathology are discussed and the current literature on the subject is reviewed.
