Why the study?
Does the octopod technique (pre-handsewn 8-branch aortic graft) provide efficient and safe reconstruction of visceral and intercostal arteries in patients undergoing open repair of extent II thoraco-abdominal aortic aneurysms?
Does the octopod technique (pre-handsewn 8-branch aortic graft) provide efficient and safe reconstruction of visceral and intercostal arteries in patients undergoing open repair of extent II thoraco-abdominal aortic aneurysms?
The octopod technique using a pre-handsewn 8-branch aortic graft is a feasible and efficient approach for extent II thoraco-abdominal aortic aneurysm repair, showing no early mortality or spinal cord injury in a small initial series.
May support feasibility of octopod technique for extent II TAAA repair; leaves open need for prospective validation before wider use.
Reconstruction of the visceral and intercostal arteries is the most challenging part in the open repair of thoraco-abdominal aortic aneurysm. For efficient and expeditious reconstruction of these branching vessels, a technique of using a pre-handsewn 8-branch aortic graft (octopod technique) has been adopted. The octopod graft was manually constructed using commercially available two 4-branch aortic grafts that were spatially oriented based on the preoperative computed tomographic images and connected each other prior to surgery. This approach was adopted in 12 open repairs of extent II thoraco-abdominal aortic aneurysms from 2015 to 2017, including 8 Marfan patients. Median pump and procedural times were 173 (102-207) min and 437 (343-489) min, respectively. There was no operative mortality or spinal cord injury. The octopod technique for open thoraco-abdominal aortic aneurysm repair showed excellent early results with high procedural efficiency.
