简要总结
Interventional strategies aim to restore tissue perfusion. However, despite the simple reopening of a narrowed artery they affect endothelial function, perpetuating dysfunctional vascular homeostasis. PTA and atherectomy might alter the endothelial function but the mechanisms are incompletely understood. The primary goal of atherectomy is vessel preparation and improving compliance, which could aid in preserving vessel functions. Aim of this study is to determine safety, efficacy, patency and vessel functions in the femoropopliteal artery following atherectomy and DCB.
