| Abstract | Purpose: To investigate if balloon angioplasty with a prolonged inflation time (>3 minutes) can prevent postdilation dissection in femoropopliteal lesions. Methods: A retrospective single-center analysis examined 294 consecutive patients (mean age 74.1±8.7 years; 215 men) with de novo femoropopliteal lesions treated with balloon angioplasty between 2013 and 2018. The patients were classified into 2 groups to compare angiographic dissection patterns: 175 patients treated with balloon angioplasty for 3 minutes (3-minute group) and 119 treated for >3 minutes (>3-minute group). Results: Mean balloon inflation time was 7.8±2.7 minutes in the >3-minute group. Severe dissections (type C or higher) were observed less frequently after balloon dilation in the >3-minute group (22.7% vs 50.9%, p<0.001); therefore, significantly more patients in the >3-minute group had successful endovascular treatment after initial balloon angioplasty (57.1% vs 38.3%, p=0.001). Additional balloon dilation was attempted more frequently in the 3-minute group (30.9% vs 14.3%, p=0.001); as a result, there were more patients in whom additional balloon dilation repaired severe dissection that occurred after the initial dilation (25.1% vs 10.9%, p=0.001). Multivariate analysis revealed that chronic total occlusion (p<0.001) and longer lesion (p<0.001) were independent predictors of severe dissection, and prolonged dilation time was independently related to preventing severe dissection (p<0.001). Among 171 patients undergoing successful balloon angioplasty without stent implantation, the Kaplan-Meier estimates of primary patency within 1 year did not differ significantly according to inflation time. Conclusion: Balloon dilation with prolonged inflation time (>3 minutes) may be effective as an initial strategy to prevent severe dissection in femoropopliteal lesions compared to inflation for 3 minutes. |
