Efficacy of chocolate balloon assisted drug-coated balloon angioplasty for the treatment of TASC Ⅱ type C/D femoropopliteal artery lesions / 实用医学杂志

ABSTRACT

Objective To evaluate the efficacy and safety of chocolate balloon assisted drug-coated balloon(DCB)angioplasty for the treatment of TASC Ⅱ type C/D femoropopliteal artery lesions.Methods The clinical data of 58 patients with TASC Ⅱ type C/D femoropopliteal artery lesions treated with chocolate balloon +DCB or plain balloon+DCB at Fuwai Central China Cardiovascular Hospital from January 2021 to October 2022 were retro-spectively analyzed.A total of 27 cases were assigned to the observation group(chocolate balloon + DCB)and 31 cases tothe control group(plain balloon + DCB).The rate of dissection and the clinical outcomes between the two groups were compared.Results The technical success rates of the observation and control groups were 88.9%and 80.6%,respectively.The rates of dissection,flow-limiting dissection,and bailout stenting were significantly lower in the observation group than of the control group(all P<0.05).Postoperative clinical symptoms of patients in both groups improved significantly compared with the preoperative period.The 12-month cumulative primary patency rate of the observation group was significantly higher than that of the control group(P<0.05).There was no significant difference in the 12-month cumulative freedom from clinically driven-target lesion revascularization rate between the two groups(P>0.05).Conclusion Chocolate balloonassisted DCB angioplasty was safe and effective for TASC Ⅱ type C/D femoropopliteal artery lesions.It reduced the rates of dissection and bailout stenting,and had better near-term outcomes than plain balloon + DCB.
