Purpose: To evaluate the early and midterm results of the endovascular treatment of patients that had an isolated iliac artery aneurysm (IIAA).
Materials and Methods: From February 2004 to April 2009, 15 patients (9 men, 6 women) with IIAA underwent endovascular treatment such as stent graft insertion or embolization. Computed tomography angiography (CTA) was performed for the diagnosis of an aneurysm and for a follow-up after treatment. The medial records and CTAs were retrospectively reviewed for analysis of the symptoms, past history of disease, combined disease, anatomical morphology of aneurysm, and complications.
Results: The mean aneurysm diameter was 36.9 mm (range: 20 mm - 80 mm). The aneurysm sites included the common iliac in 8 patients, internal iliac in 5 patients, and a combined common and internal iliac in 2 patients. Tubular stent grafts or bifurcated aorto-iliac stent grafts were used singly or mixed. The internal iliac arteries of 11 patients were embolized by microcoils or by Amplatz vascular plugs or by both methods. The technical success achieved for embolization was 93.3% (n=14). The mean follow-up period was 125.5 days (range: 7 - 701 days). The stent graft patency rate was 100%. On follow- up CTA, 1 patient experienced a type I endoleak, whereas 1 patient experienced a type II endoleak.
Conclusion: The endovascular treatment of IIAA shows positive early and mid-term results. The procedure is a safe, minimally invasive, and has a low complication rate.
