Chronischer verschluss der A. femoralis superficialis: Stellenwert der angioplastie, ballonangioplastie und stentangioplastie

Infrainguinal bypass procedures and percutaneous transluminal angioplasties (PTA) have been used to treat patients with symptomatic obstructions of the femoropopliteal artery. PTA is often the primary procedure to avoid the higher rate of morbidity associated with operation. However, long-term durability of balloon dilatation or endovascular stenting have been questioned, despite favorable primary success rates for endovascular recanalization (>90%). Clinical presentation (claudication or critical limb ischemia), quality of primary PTA result and quality of distal runoff, risk factors, comorbidity, and medication are contributing factors to long-term success. After endovascular recanalization, 2- to 3-year patency rates of 50-70% can be achieved. Additional stent implantation is helpful for removing immediate post-PTA residual stenoses. The wide range of clinical results reported in the literature can be attributed mainly to the method of patient selection.
