Comparison of the Clinical Results between Endovascular and Open Bypass Surgery for Treating Iliac Artery Occlusion

ABSTRACT

PURPOSE: This study was constructed to review our experience for the treatment for iliac artery occlusion/stenosis with performing angioplasty/stenting and open bypass surgery. METHODS: We retrospectively evaluated the 86 primary endovascular and open bypass procedures that were done for iliac artery occlusion/stenosis between 2000 and 2005. The data was divided into two groups by the procedure the endo group (31 limbs, 36%), and the bypass group (55 limbs, 65%). RESULTS: The outcomes were defined according to the reported standards of the Society for Vascular Consensus (TASC). The lesion types were significantly more severe in the patients in the bypass group (P=0.000). The initial technical & clinical success rates were 100% in both groups. The cumulative 48-month primary & secondary patency rates were 76.1% and 95.2% in the endo group and 78.0% and 93.8% in the bypass group, respectively. The perioperative complication rates were 6% in the endo group and 9% in the bypass group, respectively. The mean hospital stay was more significantly shorter in the endo group (5.4 days vs. 15.1 days, respectively, p=0.000). CONCLUSION: The treatment of iliac artery lesion with angioplasty/stenting was a safe and effective method in our experience. Selective angioplasty/stenting may be preferable to bypass surgery for treating TASC A and B type iliac artery occlusions.
