  • Title: Thrombolytic therapy in peripheral arterial occlusive disease: mechanisms of action and drugs available.
    Author: Comerota AJ, Cohen GS.
    Journal: Can J Surg; 1993 Aug; 36(4):342-8. PubMed ID: 8370015.
    Abstract:
    Catheter-directed thrombolytic therapy has become an important part of the treatment of patients with acute arterial and graft occlusion. The underlying pharmacologic principle is the activation of plasminogen, bound to fibrin within the thrombus. Guide-wire passage reliably predicts success of catheter-directed thrombolysis. The underlying disease process leading to thrombosis should be accurately identified and promptly corrected to reduce the probability of recurrent occlusion. Streptokinase (SK), urokinase (UK) and recombinant tissue plasminogen activator (rt-PA) are the three agents used to treat peripheral arterial occlusive disease. The evolution from SK to UK and rt-PA and improvements in techniques and delivery systems have led to improved success rates and lower complication rates. Patient selection, basic technical considerations and overall results are discussed here. The currently available thrombolytic agents, as well as those being developed, are reviewed to provide background information for current and future applications.
