Proximal Anastomosis for the Treatment of Acute Type A Aortic Dissection: An Operative Technical Note
Key result
Proximal graft invagination technique aims to improve hemostasis and valve coaptation in acute type A dissection.
Why the study?
A proximal anastomotic technique is needed to facilitate aortic valve coaptation, reduce suture-line tension, and improve hemostasis in acute type A aortic dissection surgery.
Population
Patients with acute type A aortic dissection undergoing supracoronary ascending aortic replacement
Comparison

Implication
May aid proximal hemostasis in acute type A repair; leaves open comparative validation before wider adoption.
Key Points
- Describe an operative proximal anastomotic technique utilizing an invaginated and everted prosthetic graft cuff for supracoronary ascending aortic replacement in acute type A aortic dissection.
- Invaginating a short segment of prosthetic vascular graft at the level of the sinotubular junction.
- Everting the prosthetic graft segment to generate a reinforced, double-layered proximal anastomotic cuff.
- Facilitates the anatomic restoration of aortic valve leaflet coaptation.
- Reduces mechanical tension across the proximal suture line and enhances intraoperative hemostasis in friable, dissected aortic tissue.
