Coil embolization for type IA endoleak after thoracic branched endoprosthesis placement in type B dissection.

Although the use of thoracic branched endoprosthesis to treat thoracic aortic pathologies is increasing, literature regarding the management of associated complications is limited. A large left subclavian artery infundibulum can lead to type IA endoleaks around the base of the graft branch/left subclavian artery due to a decreased seal zone along the greater aortic curvature. Here we present three cases of successful coil embolization to treat type IA endoleak after thoracic branched endoprosthesis.
