[Current status of fibrinolysis--a literature review of 25 years of fibrinolytic treatment].

: Thrombolytic therapy is an effective, rapid method in treatment of massive lung embolism and major deep venous thrombosis extending to the caval vein. Besides resolution of the thrombus and improving hemodynamics, it prevents evolution to chronic pulmonary hypertension or postphlebitic syndrome. To have a beneficial effect in the early course of acute myocardial infarction, thrombolytic therapy should be instored within about three hours after the onset of pain; a real brief time limit. Intracoronary or systemic fibrinolysis later than the three hours period does not improve cardiac wall motion and hemodynamics and cannot assure infarct size reduction in spite of reestablished coronary flow. In peripheral arterial disease, fibrinolytic therapy of thrombosed grafts or vessels facilitates detection and unmasking of the underlying anatomical lesion permitting definite therapy (graft revision, percutaneous transluminal angioplasty). Selective intraarterial infusion has given encouraging results. Thrombolysis is a reasonably safe therapeutic method, on the condition of respecting all contraindications and avoiding unnecessary punctions. Allergy and hyperthermia are mostly benign and responsive to medical treatment. Cost-effectiveness renders streptokinase the most applicated thrombolytic agent.
