OBJECTIVE: To evaluate the results of a new thrombin sealant (Recothrom) for the treatment of arterial pseudoaneurysms (PDAs). METHODS: We reviewed 47 consecutive patients prospectively entered in a dedicated data set who underwent ultrasound-guided percutaneous thrombin injection to treat PDA. End points were PDA recurrence, need for reintervention, and related complications such as limb ischemia or allergic reactions. RESULTS: Twenty-six patients were females (55%) and the median age of the entire group was 71 years (range, 45-87). The mean size of the PDA was 2.3 ± 0.9 cm. The mean injected volume was 2.4 ± 1.4 mL containing 500 ± 320 units. Recurrence of the PDA occurred in 4 (8.5%) patients and was not related to anticoagulation status, body habitus, platelets levels, or use of antiplatelets. All recurred PDAs were successfully sealed with a second (n = 3) and a third injection (n = 1). There was no distal embolization or allergic reactions and no surgical intervention was required. CONCLUSION: The new human recombinant thrombin (Recothrom) is a safer nonimmunogenic option with similar success rates of other fibrin glue sealants.
