A peculiar case of iliac vein aneurysm

Abstract

Venous abdominal aneurysm is a rare entity, especially at the iliac vein. This condition is very rare and is usually grave when the aneurysm ruptures. It requires immediate treatment, surgically or by endovascular technique, to prevent such complications. Most of the iliac vein aneurysm cases are associated with arteriovenous fistula (AVF). We report the case of a 33-year-old male who presented with iliac vein aneurysm secondary to AVF. He was treated surgically after a failed endovascular procedure. The venous aneurysm had numerous feeder vessels which were difficult to manage intraoperatively. It prompted us to ligate the common iliac artery and do grafting between the common iliac artery and the common femoral artery. Iliac vein aneurysm diagnosis requires precise clinical suspicion, and the treatment is based on patients' clinical presentation and radiological features. Use of appropriate imaging modalities facilitates a correct preoperative diagnosis which consequently improves the surgical outcome.
