Percutaneous Thrombin Injection of a Pulmonary Artery Pseudoaneurysm Refractory to Coil Embolization

A 57-year-old white man with a hypermetabolic right upper-lobe mass underwent treatment with wedge resection. During the immediate postoperative period, a right middle-lobe pulmonary artery pseudoaneurysm developed. After unsuccessful transcatheter coil embolization, fluoroscopically and sonographically guided percutaneous thrombin injection was performed, with complete thrombosis of the pseudoaneurysm.
