Endovascular management for isolated iliac artery aneurysm / 中国普通外科杂志

ABSTRACT

Objective To evaluate endovascular management for isolated iliac artery aneurysm (IIAA). Methods From May 1997 to Jan 2006, 15 IIAA cases underwent endovascular treatment, including 12 true aneurysms and 3 psudoaneurysms. There were 9 common iliac artery aneurysms (CIAA), 3 internal iliac artery aneurysms (IIAA) , and 3 external iliac artery aneurysms (EIAA). The average diameter was (5. 97?1. 49) cm (3. 5-9. 0 cm). IIAA was treated with metallic coils and CIAA/EIAA by stent-grafts. Results Unilateral internal iliac artery was preserved in 14 cases, and bilateral internal arteries were preserved in one case. Postoperative endoleak was found in 2 cases. There was no other major complications nor mortality. One case suffered buttock claudication because of internal iliac artery exclusion. The operation time was 1. 9?1. 1 h, blood loss was 126. 7?70. 1 ml. Patients were up and about after 2. 1?1. 1 d, hospital stay was 5.5?4.7 d. Conclusions Endovascular treatment is safe and effective for isolated iliac artery aneurysm. Internal iliac artery preservation and prevention of endoleak is of great importance.
