Long-term results after endoprosthesis replacement and stenting operations of the iliac arteries after hybrid interventions

Due to constantly evolving endovascular technologies over the last two decades there have been significant changes in diagnosis and treatment of lower extremity arterial atherosclerosis. The introduction of stent-grafts was the next step in the development of transluminal surgery. The aim of this study was to compare the immediate results and postponed resultin patients undergoing stent or endoprosthesis replacement in iliac arteries. In Clinical Hospital № 119 FMBA of Russia was done 274 hybrid operation from 2007 to 2013, which consisted of endovascular intervention in the iliac arteries (endoprosthesis or stent) and the open surgical reconstruction of the distal arteries in patients with atherosclerotic lesions. Patients were divided into two groups. The first group (54 ) consisted of patients who were implanted prosthesis, a second (220 ) - uncoated stent. A good immediate results (100% in the arthroplasty and 99% in the stenting group) has been reached in both groups. Long-term results were followed up for six years in 54% of patients. Among the late complications of the most common in the stenting group marked in was stent restenosis. Any cases of restenosis was not revealed in the arthroplasty group. The trend towards better long-term patency in group arthroplasty compared with stenting group marked the second year of observation, and significantly better results were obtained from the fourth year. Thus, the intraluminal stent graft, in contrast to the uncoated stent can potentially prevent restonosis.
