Analysis of mid-term outcomes of iliofemoral artery complex lesions treated with hybrid technique

Objective To analyze the mid-term outcomes of hybrid surgery for iliofemoral artery complex lesions. Methods We conducted a retrospective analysis of the clinical data on 16 patients with iliofemoral artery complex lesions who underwent hybrid technique treatment from September 2013 to December 2014. We evaluated the mid-term clinical efficacy in accordance with international standards. Results Technical and hemodynamic success rate were 100%. Mean ankle-brachial index increased from 0.42±0.15 to 0.85±0.11 (P<0.001). With a mean follow-up period of 19 months (ranged from 13 to 28 months), no severe perioperative complications and death were recorded. One case with dry gangrene of first toe of right foot was treated with toe amputation surgery, for the remaining cases, skin temperature improved obviously, intermittent claudication and rest pain disappeared or improved significantly after procedure and the foot ulcer healed. Eighteen months primary patency and primary-assisted patency rates were 83.2% and 91.4%, respectively. Conclusion Hybrid procedure for complex iliofemoral lesions can effectively avoid cross-joints stenting and preserve the deep femoral artery. It can also improve the chances and efficiency of opening occlusion, better solve the inflow and outflow tract hemodynamics problems and improve the long-term patency rate.
