[Endovascular and open reconstructive treatment of arterial occlusive disease of the lower extremity in the critical ischemia stage].

Arterial revascularization is mandatory in the vast majority of patients with critical ischemia in the leg. Open surgical and percutaneous catheter procedures (angioplasty, local thrombolysis, clot extraction) can each be applied alone or in combination to avoid major amputation. Given the low invasiveness and morbidity of percutaneous techniques, they should be the method of first choice, provided suitable occlusion morphology is available. If catheter therapy is not successful, surgery can be performed. Five-year patency after surgery for femoropopliteal obstructions is approximately 60% and 40% after catheter therapy. Iliac revascularization shows higher patency rates for both procedures. Percutaneous catheter techniques can be an alterative to vascular surgery, but more importantly both can be used as complementary procedures in the same patient, provided there ist good cooperation between the vascular surgeon and the person during the interventional angiology.
