Description
Fadhel Nabil Hamidani and colleagues report the late embolization of a patent foramen ovale closure device, retrieved without surgery. Their 2026 case paper follows a 68-year-old woman who underwent closure after ischemic stroke. Device embolization is rare and usually early, but at three-month follow-up the device could not be seen on transthoracic or transesophageal echocardiography, and CT angiography located it in the distal abdominal aorta.
Retrieval used a percutaneous snare technique through right femoral arterial access, with stepwise sheath upsizing to 16-French. An initial snare captured one disc but could not retract it, while a second snare system secured engagement and withdrawal, finished with biopsy forceps. Retrieval was complicated by an infrarenal aortic dissection managed conservatively. Three weeks later the patient had a recurrent ischemic stroke and underwent repeat closure with a larger device without further complications. The case shows late embolization can still be handled percutaneously.
