Antegrade is including cross procedures, TASC: Trans-Atlantic Inter-Society Consensus, PACSS: The peripheral artery calcification scoring system, Kockelkoren Score; <7 intimal dominant, ≥7 non-intimal dominant plaque formation. SFA: Superficial femoral artery, CTO: Chronic total occlusion Statistical significance was defined as p < 0.05. Continuous variables are presented as mean ± standard deviation
