A Comparative Analysis Of Endovascular Stenting And Traditional Bypass Surgery In The Treatment Of Aorta-iliac Occlusive Disease

ObjectivesTo evaluate the clinical effect of endovascular stenting and main - double femoral artery bypass surgery in the treatment of aorta-iliac occlusive disease, and the indications, complications, patency rate and technical points are also discussed.MethodsFrom April 2011 and October 2013, there were 105 patients with aortoiliac occlusive disease accepted treatment in our department totally.34 patients(41 limbs) were choosen from these patients. Clinical features include claudication in 17, resting pain 7 and ulcer/gangrene 10 patients, respectively. According to two procedures which were divided into two groups,We summarized preoperative condition, indications, contraindications and operative method of the patients. The postoperative complications and patency rate were also observed.ResultsAll patients with a total of 34 cases were followed up,29 male(85.29%) and 5 female(14.71%). with a mean age (range:81-48 years),34 patients had completed follow-up of 3-12 months(mean 10.4±3.7 months). Early complication rate was 11.8% in the stent group occurs, bypass group was 23.5%, without a meaningful different(P>0.05). Stent group before and after surgery ABI values were 0.25 ± 0.21 and 0.51 ± 0.25, with a meaningful different (P<0.05). Before and after bypass surgery group ABI values were 0.34 ±0.19 and 0.57 ± 0.22, with a meaningful different (P<0.05). Stent patency rate was 12 months 88.2%, the bypass group was 82.4%, The patency rate of these two group have a meaningful different(P<0.05).ConclusionsEndovascular stenting has merits like less invasion,less bleeding,faster recovery, low complication rate,etc. this was an ideal surgical for the treatment of aortailiac occlusive disease. However, there was literature that, after recanalization rates and long term patency of endovascular stenting was much lower than the main - double femoral artery bypass surgery. Yet the patency rate of two surgical methods should be further observed because of limited case number and follow-up time.
