Objective 

This study presents technical aspects, midterm results and complications using iliac bifurcation devices (IBD) and determine its feasibility and safety in patients with aortoiliac or common iliac artery aneurysms (CIAA), including those with bilateral disease. METHODS: Since 2006, 47 IBD were implanted in 37 patients and followed for a mean ±SD of 11,6 ± 7,5 months (range 2 to 31).Treated CIAA were unilateral in 27 patients and bilateral in 10. Two patients with bilateral CIAA did not have simultaneous aortic aneurysm and one had an anastomotic pseudoaneurysm. Two patients underwent combined thoracoabdominal aneurysm treatment with branched endografts and one underwent combined juxta-renal aneurysm repair with a fenestrated device. Eleven (23,4%) CIAA received the Helical Iliac Side Branch device and the remaining 36 (76,6%) received the Zenith Bifurcated Iliac Sidebranch.

Results 

Technical success was 97,3% of 47 intended to treat CIAA (migration failure in one patient). There were no deaths and no conversions to open repair. During follow-up five (10,6%) hypogastric branch occlusions occurred in five patients, all within the first 12 months, and one patient developed persistent buttock claudication. Two unilateral occlusions occurred in patiens with bilateral repair, sparring the contralateral CIA. No endoleak, modular side branch disconnection or late iliac rupture were observed. Cumulative patency was 74% up to 31 months.

Conclusions 

Bilateral CIAA treatment with IBD should be considered standard treatment for bilateral disease.The use of IBD to preserve pelvic circulation is safe and feasible for most patients CIAA, including those with concomitant Abdominal or Thoracoabdominal Aortic Aneurysms.
