Aortic arch banding procedure for proximal type I endoleak after thoracic endovascular aneurysm repair with the chimney technique

An aortic arch banding procedure was performed on an 82-year-old man for treatment of proximal type I endoleaks 2 days after he had undergone emergency thoracic endovascular aortic repair with the chimney technique for a ruptured aortic arch aneurysm. Contrast-enhanced computed tomography after the second procedure demonstrated significant shrinkage of the aneurysmal sac as well as a complete disappearance of the endoleaks. The basic concept of this technique is to treat the type IA endoleak, including possible gutter endoleaks, by creating a new proximal seal zone distal to the chimney graft using a banding technique.
