PURPOSE: To evaluate the use of percutaneous transcatheter thrombolysis in the treatment of thrombosis due to radial artery cannulation. METHODS AND RESULTS: Seven patients (4 women; age range 41-62 years) with symptomatic cannulation-induced thrombosis and failure to improve after systemic anticoagulation underwent 8 catheter-directed thrombolytic infusions at our institution over a 3-year period. Access was either antegrade through the brachial artery or retrograde through the femoral artery. Thrombolytic infusions with urokinase began 2 to 12 days (average 6) after removal of the radial artery catheter. The thrombolytic infusion was successful in 5 of 7 patients based on angiographic flow restoration with <20% residual thrombus and significant clinical improvement in the ischemia. CONCLUSIONS: When systemic anticoagulation has failed, percutaneous catheter-directed thrombolytic infusion appears to be effective in the treatment of most patients with severe ischemic hand symptoms due to thrombosis after radial artery cannulation.
