[Local lysis therapy in acute arterial thrombosis].

Acute thrombotic arterial occlusion is a complication of chronic vascular arterial disease. The arteriogram usually reveals a sudden occlusion and the collateral vessels. Treatment with low-dose fibrinolytic therapy is widely accepted. A combination of low-dose fibrinolysis, aspiration embolectomy and angioplasty yields the best primary success rate. In cases of sudden popliteal occlusion and dilating arteriopathy ultrasound sonography should be used to exclude the presence aneurysm which is a contraindication for fibrinolysis. There is a high risk of peripheral embolisation, in the presence of an aneurysm and this may cause severe deterioration of the arterial blood supply.
