Percutaneous repair of abdominal aortic pseudoaneurysm by catheter-based delivery of thrombin.

Purpose: To present a case in which thrombin was injected percutaneously to treat an aortic pseudoaneurysm.

Case Report: A 63-year-old man developed a large pseudoaneurysm in the abdominal aorta after surgical fenestration and patch aortoplasty for acute type B aortic dissection with malperfusion syndrome. Transcatheter delivery of 1500 units of thrombin resulted in complete thrombosis of the pseudoaneurysm sac. No complications occurred. Twelve months after the procedure, the pseudoaneurysm was completely resolved on computed tomography.

Conclusion: Thrombin continues to prove its safety and efficacy for the treatment of pseudoaneurysms at numerous anatomical sites, including the abdominal aorta.
