[MO-89] Comparison of acute results caused by stepwise or conventional balloon angioplasty for the endovascular treatment to the femoro-popliteal artery.
Background: The endovascular treatment to femoro-popliteal lesions has been developing with novel techniques and devices. Currently, drug coated balloon (DCB) can be available in japan. Therefore it is important how the balloon angioplasty should be performed for vessel preparation before DCB. However, the optimal balloon angioplasty to the femoro-popliteal artery remains unclear. The aim of this study is to compare acute results caused by stepwise or conventional balloon angioplasty.
Methods: Patients with femoro-popliteal lesion treated by stepwise balloon angioplasty (S-BA) or conventional balloon angioplasty (C-BA) were analyzes. Provisional stenting rate and dissection type as acute result were compared between stepwise and conventional balloon angioplasty.
Results: Between 1st January 2018 and 31th October 2018, S-BA was performed in 92 patients (aged 74.8±7.7 years) and C-BA was performed in 38 patients (aged 75.2±8.3 years) in our hospital. In patient characteristics, the diabetes rates was 53.2% and hemodialysis rates was 43.5% in S-BA group and each was 42.1%, 44.7% in C-BA group (p=0.25, 0.90, respectively). In lesion characteristics, there was significant difference between the two groups regarding the rate of type C or D lesions for TASCⅡ(52.1% in S-BA group and 28.9% in C-BA group, p=0.01). Despite the adverse situation for S-BA group, the acute results showed relatively good; provisional stenting rate was 7.6% in S-BA group and 13.2% in C-BA group (p=0.38), and severe dissection patterns, defined as type C or higher, were 27.2% in S-BA group and 31.6% in C-BA group (p=0.62).
Conclusions: Stepwise balloon angioplasty can be feasible to obtain minimum vessel dissection and maximum acute gain in femoro-popliteal arterial lesion.
