A Novel Technique for Thoracic Endovascular Graft Explantation.

Thoracic endovascular aortic repair (TEVAR) explantation remains a challenge due to endovascular graft ingrowth into the aortic wall with time. Surgical access into the aortic arch can be difficult either via sternotomy or thoracotomy, and proximal barbs become engaged firmly into the aortic wall. Explantation often requires extensive thoracic aortic resection, sometimes from the distal aortic arch to the abdominal aorta, followed by reconstruction, risking injury to surrounding neurovascular structures and even death.
