[Intra-arterial thrombolysis in peripheral bypass and arterial occlusions. Preparation and practical procedure].

The aim of this article is to describe our technique for performing intra-arterial thrombolysis. This way of treating arterial and graft occlusions demands close cooperation between interventional radiologist and vascular surgeon. The intra-arterial thrombolysis is preceded by clinical examination, haematological tests, angiography and information to the patient. The main indications are pain at rest and serious claudication due to acute or subacute occlusion of grafts or native arteries to the lower extremities. The most important contraindications are conditions predisposing to bleeding. The most common adjunct percutaneous treatment is balloon angioplasty. Surveillance is compulsory in order to discover complications at an early stage.
