Isolated internal iliac artery aneurysm eleven years after tube graft repair of an abdominal aortic aneurysm: Case report and literature review

Abstract

Internal iliac artery (hypogastric) aneurysms are most commonly associated with common iliac or other arterial aneurysms. Isolated internal iliac aneurysms are quite rare and represent about 1/2% of intracorporal aneurysms. The occurrence of an isolated internal iliac artery aneurysm many years after repair of an abdominal aortic aneurysm, and its successful surgical management have not been previously reported. An 84-year-old Caucasian male presented with acute left femoro-popliteal deep vein thrombosis 11 years after repair of an abdominal aortic aneurysm with insertion of a knitted Dacron tube graft. In the course of his workup he was found to have an isolated 5-cm right, hypogastric, arterial aneurysm. After treating the patient for this deep vein thrombosis, the internal iliac artery aneurysm was repaired via a transperitoneal approach, using the technique of obliterative endoaneurysmorrhaphy. The natural history, diagnosis, and options for treatment modalities of isolated internal iliac arterial aneurysms are presented with a review of the literature.
