Aneurisma venoso iliaco primario: presentación de un caso y revisión de la bibliografía

Iliac venous aneurysms are among the least frequent occurring in the venous system. We found seven primary cases reported in the literature. This is the first case of a thrombosed external-common iliac vein since Hurwitz reported the first aneurysm of the iliac vein. Most authors agree that the intra-abdominal location presents a potential risk of pulmonary embolism and thrombosis; thus, when the aneurysm is symptomatic and even asymptomatic and is not fully thrombosed, prophylactic surgical resection involving end-to-end anastomosis, lateral phleborrhaphy or repair by means of a graft would be indicated. The diagnosis and follow-up can be accomplished correctly by duplex, but we believe that the moment it is detected, a complementary MR angiography should also be performed.
