Urokinase lysis for acute left subclavian artery thrombosis after placement of infusion catheter: report of two cases

Abstract

We present two cases of acute subclavian and/or axillary arterial occlusion after transaxillary catheterization with an implantable port for hepatic arterial infusion chemotherapy. They were successfully treated with thrombolytic therapy using intraarterial administration of urokinase without removal of the infusion catheter system. We consider that this treatment is suitable for managing acute thrombosis of the conduit artery after catheterization for hepatic arterial infusion chemotherapy.
