Abstract

PURPOSE
To report the results of treatment isolated iliac arterial aneurysms by interventional procedures.
MATERIALS AND METHODS
Over a period of 5 years, 7 isolated iliac artery aneurysms (4 in the common iliac artery, 3 in the internal iliac artery) in 7 patients (3 women, 4 men; mean age, 65.7 years) were treated using interventional procedures. The mean aneurysm size was 35 mm (range, 30-45 mm). The common iliac aneurysms were treated using a unilateral stent graft (2 balloon expandable, 2 self-expandable) with coil embolization of the internal iliac artery (n = 3), except for 1 aneurysm that ruptured. Coil embolization alone was performed for aneurysms involving only the internal iliac artery (n = 3).
RESULTS
All patients were treated successfully, except for 1 with an initial remnant of type 2 endoleak. There were no perioperative complications. No leakage or complication occurred at the mean follow-up of 14 months (range 2-29 months). One patient with a ruptured aneurysm died of multi-organ failure during the follow-up period. Three aneurysms had decreased in size on follow-up CT.
CONCLUSION
Interventional procedures with stent grafting and coil embolization are safe and effective treatments for isolated iliac artery aneurysms.
