A new hybrid graft for open thoracoabdominal aortic aneurysm repair.

The Thoracoflo graft was developed as a new hybrid device for thoracoabdominal aortic aneurysm (TAAA) repair. The aim was to offer strategies to mitigate perioperative mortality/morbidity through a combined endovascular thoracic and open abdominal aortic singlestage operation. The SPIDER technique for graft implantation allows temporary, pulsatile distal perfusion of visceral, renal, and iliac arteries via a side-branch attached to the common iliac artery following the deployment of the stent-supported part of the device. Thoracotomy, radiation, and extracorporeal circulation (ECC) can be avoided, while enabling reimplantation of visceral, renal, and lumbar arteries (1-5).
