Abstract:
Objective:To investigate the influence of plain old balloon angioplasty (POBA) and drug-coated balloon (DCB) dilatation on clinical efficacy and safety in patients with lower extremity arteriosclerosis obliterans.Methods:Seventy patients with lower extremity arteriosclerosis obliterans from February 2016 to February 2018 in Central Hospital of Yuncheng City, Shanxi Province were chosen. The patients were divided into control group (35 patients) with POBA dilatation and observation group (35 patients) with POBA and DCB dilatation by random sampling method. The target vessel patency rate, target lesion revascularization rate, minimum lumen diameter and ankle brachial index (ABI) level before and after surgery, Rutherford classification in follow-up after surgery, late lumen loss after surgery and perioperative complications incidence of 2 groups were compared.Results:The target vessel patency rate 6 and 12 months after surgery in observation group was significantly higher than that in control group: 85.71% (30/35) vs. 62.86% (22/35) and 80.00% (28/35) vs. 48.57% (17/35), and there was statistical difference ( P<0.05). The target lesion revascularization rate in observation group was significantly lower than that in control group: 8.57% (3/35) vs. 28.57% (10/35), and there was statistical difference ( P<0.05). The minimum lumen diameter 6 and 12 months after surgery in observation group was significantly more than that in control group and before surgery: (3.20 ± 0.66) mm vs. (1.53 ± 0.38) and (0.45 ± 0.09) mm, (2.97 ± 0.60) mm vs. (1.40 ± 0.35) and (0.45 ± 0.09) mm, and there was statistical difference ( P<0.05). The ABI 6 and 12 months after surgery in observation group was significantly higher than that in control group and before surgery: 0.86 ± 0.17 vs. 0.63 ± 0.09 and 0.24 ± 0.06, 0.82 ± 0.14 vs. 0.60 ± 0.08 and 0.24 ± 0.06, and there was statistical difference ( P<0.05). The proportion of late lumen loss and Rutherford classification >3 12 months after surgery in observation group were significantly less than those in control group: (0.42 ± 0.10) mm vs. (1.59 ± 0.32) mm and 17.14% (6/35) vs. 57.14%(20/35), and there were statistical differences ( P<0.05). The perioperative complications incidence in observation group was significantly lower than that in control group ( P<0.05). Conclusions:Compared with POBA dilatation, DCB dilatation in the treatment of patients with lower extremity arteriosclerosis obliterans possesses better clinical efficacy and safety.
