title: Local intra-arterial streptokinase therapy for acute peripheral arterial occlusions. Should thrombolytic therapy replace embolectomy?
abstract: Locally administered low-dose streptokinase was used in 13 patients with acute arterial occlusions. Systemic fibrinolytic effects were noted in each of 11 patients in whom some effective thrombolysis was demonstrated. In the two patients with no angiographically demonstrable thrombolysis, a systemic lytic effect was absent. Bleeding complications were frequent (31%). Three patients required amputations and one patient died. The systemic lytic effects of streptokinase appear to be necessary for complete clot lysis. Locally administered streptokinase appears to have no significant benefit compared to high-dose systemic administration. Occlusions accessible to balloon embolectomy should probably be treated surgically, reserving fibrinolytic therapy for inaccessible lesions. More research is needed to clarify the specific indications, as well as to determine optimal methods of administration and dosage.
