Implication

Retrospective study shows severe arterial dissection worsens long-term patency after balloon angioplasty, highlighting risks in complex lesions.

Key Points

To evaluate angiographic dissection patterns following balloon angioplasty in superficial femoral artery lesions, determine their impact on clinical outcomes, and identify predictors of severe dissection.
Retrospective multicenter analysis of 621 patients (mean age 72.8±9.5 years; 414 men) with 748 symptomatic de novo superficial femoral artery lesions undergoing endovascular therapy.
Vessel dissection was classified into 7 grades (none, types A–F) using a modified coronary scale, defining types C–F as severe; 555 lesions received bailout nitinol stents and 193 were treated with balloon angioplasty alone.
Two-year follow-up evaluated primary patency and clinically driven target lesion revascularization in the 193 lesions managed with balloon angioplasty alone.
Severe dissection (types C–F) occurred in 42% of all lesions (314/748), including type C (5%), type D (24%), type E (9%), and type F (4%), while no dissection occurred in 16% and mild dissection (types A–B) in 42%.
In lesions treated with angioplasty alone, severe dissection significantly reduced 2-year primary patency and increased clinically driven target lesion revascularization compared with nonsevere dissection (both p<0.001).
Multivariate analysis identified reference vessel diameter <5 mm (p=0.001), lesion length >15 cm (p=0.001), and chronic total occlusion (p<0.001) as independent predictors of severe dissection.
