Balloon angioplasty for symptomatic inferior vena cava aneurysm

Aneurysms of the inferior vena cava (IVC) are uncommon. Symptomatic patients usually present with thrombosis and venous obstruction. Classification is based on location and the presence or absence of congenital IVC interruption. Treatment options include observation, open surgical resection, and endovascular modalities, of which coil embolization and stent graft placement have previously been described. We report the case of a patient with a 5.0-cm infrarenal IVC aneurysm and associated congenital stenosis who successfully underwent balloon angioplasty. Whereas management should be determined on an individual basis, balloon angioplasty is a plausible treatment for IVC aneurysms in the setting of congenital stenosis.
