title: Percutaneous injection therapy for a peripheral pulmonary artery pseudoaneurysm after failed transcatheter coil embolization.
abstract: Coil embolization to occlude the feeding artery of a pseudoaneurysm is an effective treatment to control hemoptysis. However, a feeding artery of the pseudoaneurysm may not be identified at pulmonary angiography, resulting in a failure to obtain embolization. We describe here two cases of a Rasmussen aneurysm that was successfully treated with percutaneous injection of thrombin (case 1) and N-butyl cyanoacrylate (case 2) under ultrasonographic and fluoroscopic guidance after failed transcatheter coil embolization.
