Coil embolization of persistent false lumen after type A dissection repair.

A 44-year-old man with a type A dissection repair 5 years earlier presented with progressive enlargement of the residual arch and thoracic aorta. Flow into the false lumen from the distal aortic suture line was evident on contrast-enhanced computed tomography. Through a redo hemisternotomy, the false lumen was accessed directly. An Amplatzer plug was deployed within the narrowed neck of the false lumen proximal to the enlarged false lumen within descending aorta. Interlocking coils were deployed proximal to the Amplatzer plug, resulting in thrombosis of the false lumen.
