Therapeutic Alternatives for Subacute Peripheral Arterial Occlusion Comparison by Outcome, Length of Stay, and Hospital Charges

Thrombolytic therapy using streptokinase or urokinase has been shown to be a viable alternative to surgical thrombectomy in patients with subacute peripheral arterial occlusion. Urokinase is associated with higher success and lower complication rates than streptokinase, but the cost of urokinase is at least seven times higher. To address questions of utility and effectiveness in the treatment of subacute peripheral arterial occlusions, the authors designed a retrospective study of patients treated either by surgical thrombectomy (n = 70), thrombolysis with streptokinase (n = 19), or thrombolysis with urokinase (n = 22). Outcome of therapy, length of hospital stay, and total hospital charges in the three groups were examined. Treatment successes in the three groups, defined as complete clearing of the occluded segment with patency maintained for 60 days, were 76% for thrombectomy, 32% for streptokinase, and 64% for urokinase. Total duration of hospitalization was 21.1, 21.3, and 11.5 days (P
