Delayed rupture of an internal iliac artery aneurysm following proximal ligation for abdominal aortic aneurysm repair

This is a report of a patient presenting with a contained rupture of an internal iliac aneurysm following proximal ligation after abdominal aortic aneurysm repair three years earlier. The patient presented with a large pelvic mass with symptoms of urgency, frequency, dysuria, tenesmus and fevers associated with anemia. Following evacuation of the aneurysm and direct suture ligation of the distal branches of the internal iliac artery, the patient's aortic graft was covered with omentum which also filled the pelvic cavity. The importance of proximal and distal control of aneurysms and/or the importance of complete luminal control of internal iliac artery aneurysms is emphasized by this case.
