Patency of Branch Vessels Reimplanted During Thoracoabdominal Aortic Replacement: Implications for the Surgical Technique
Kim and colleagues retrospectively analyzed long-term patency of reimplanted branch vessels following thoracoabdominal aortic aneurysm repair in 168 patients. Patency rates were high for visceral branches. For segmental arteries, patency rates depended on reimplantation technique and were worst for graft interpositions.
