Objectives: Isolated iliac artery aneurysms (IAAs) are rare, but nonetheless life-threatening when ruptured. The endovascular approach has taken over open repairs in time. The reported data is constituted of a retrospective series. We reviewed our 10-year-long experience with elective endovascular treatment of iliac aneurysms.
Methods: Data regarding 22 patients with 24 IAAs treated with endovascular stent grafting between 2005 and 2015 were reviewed.
Results: Twenty-two patients (aged 68.4 ± 9.6 years, range 50-82) with 24 unilateral or bilateral iliac aneurysms were treated. Twenty patients (91%) were male. Two patients with unilateral IAA had prior abdominal aortic aneurysm (AAA) surgical repair. The mean aneurysm diameter was 4.8 ± 2.1 (3.8 to 7.1) mm. Procedural success rate was 100%, only one patient with an iliovenous fistula had periprocedural type II endoleak. Internal iliac artery coil occlusion was applied in 16 of 24 procedures (66%). Thirty-day mortality included one patient (4%).
Conclusion: Endovascular repair is the preferred approach for isolated IAAs. Because of the retrospective nature of data sets, larger cohorts are necessary for better definition of morbidity and mortality rates.
