Abstract:
Objective:To compare drug-coated balloon (DCB) and standard angioplasty balloon (SAB) in the treatment of postoperative in-stent restenosis (ISR) in patients with arteriosclerosis obliterans (ASO) of the lower extremity.Methods:From Jan 2017 to Dec 2018, 43 ISR patients after percutaneous transluminal angioplasty for ASO of the lower extremity at our hospital were enrolled.Patients were divided into 2 groups with 18 patients treated by DCB and 25 by SAB. The patients were followed up for 6~12 months.Results:There was no significant difference in the incidence of complications between DCB group and SAB group ( P>0.05).Compared with that in SAB group, the plasma level of ET-1 in DCB group was lower while NO was higher at 6, 24 h and 2 weeks after surgery ( P<0.05), there was no significant difference in P-selectin ( P>0.05). The ABI values in both groups increased, and that in DCB group were higher than SAB group at 6 and 12 months after surgery ( P<0.05). The lumen loss in DCB group at 6 and 12 months after surgery was significantly lower ( P<0.05). At 6 and 12 months, the primary patency of target lesions in the DCB group was 100.00% and 88.89%, which was higher than the 72.00% and 52.00% in the SAB group ( P<0.05); the CD-TLR rate in the DCB group was 11.11%, which was lower than 48.00% in the SAB group ( P<0.05). Conclusion:DCB comes with lower postoperative ISR in ASO patients of the lower extremity.
