A One-year Study Of Endovascular Treatment For Aortoiliac Occlusive Disease

Objective:To study the patency of the aortoiliac occlusive disease in patients with main iliac artery occlusion after endovascular treatment for one year.Methods:A total of 72 affected limbs with aortoiliac occlusive disease who received endoscopic treatment in the Vascular Surgery Department of the First Affiliated Hospital of Guangxi Medical University from 2015 to 2020 were analyzed.According to the two different treatment methods,the patients were divided into group A,percutaneous transluminal angioplasty and group B,percutaneous transluminal angioplasty + stent implantation group.Clinical data(including imaging data,TASC II classification,length of occlusion,ABI,Rutherford grading,etc.)were recorded before surgery,3-7 days after surgery,1month after surgery,3 months after surgery,6 months after surgery,and 12 months after surgery.The postoperative patency rate,ABI and Rutherford degradation of the two endoscopic treatments were analyzed to evaluate the efficacy of the two endoscopic treatments in patients with aortoiliac occlusive disease.Results:According to imaging examination,the patency rates of group A3-7 days after surgery,1 month after surgery,3 months after surgery,6 months after surgery and 12 months after surgery were 100%,94.74%,84.21%,78.95%and 68.42%,respectively.The corresponding patency rates of group B were100%,98.11%,94.34%,92.45% and 90.57%,respectively.It can be considered that the patency change trend of the two groups is significantly different(P(27)0.05),and the patency rate of group B is significantly better than that of group A and is more than 90%,which is an ideal patency rate.The ABI of the affected limb in group A before surgery,3-7 days after surgery,1 month after surgery,3 months after surgery,6 months after surgery and 12 months after surgery were(0.2967±0.2250),(0.9579±0.0580),(0.9406±0.0537),(0.9180±0.0617),and(0.8897±0.0),respectively468),(0.8724±0.0399);The corresponding ABI of group B were(0.2138±0.1391),(0.9772±0.0565),(0.9725±0.0571),(0.9686±0.0564),(0.9587±0.0294)and(9679±0.0450),respectively.There was no significant difference in ABI between the two groups3-7 days after surgery and 1 month after surgery(P(29)0.05),but there were significant differences in ABI between the two groups 3 months after surgery,6months after surgery,and 12 months after surgery(P<0.05).The efficacy of ABI in group B was significantly better than that in group A.Moreover,ABI values of mild lower extremity ischemia were found in group A 6 months and 12 months after surgery.Rutherford degradation of patients in both groups had a change in the component ratio of degradation at each follow-up.There was no significant difference in the composition ratio of Rutherford degradation trend between 1month and 3 months after surgery(P(29)0.05).There was A significant difference in Rutherford degradation trend composition ratio between 6 months and 12 months after surgery(P(27)0.05),and the Rutherford degradation trend of group B was better than that of group A.Conclusion:There was no significant difference in short-term results between stenting and percutaneous transluminal angioplasty in patients with aortoiliac occlusive disease within 3 months,but the effect of stenting was significantly better than percutaneous transluminal angioplasty after 3 months,and stenting could achieve a satisfactory long-term rate.
