The short-term efficacy of adventitial inversion with graft eversion anastomosis for the reconstruction of the aortic sinus in the root treatment of aortic dissection.

Background: The surgical approaches for a mildly affected aortic sinus (AS) are varied and controversial. Here, the AS was reconstructed using the extended adventitial inversion with graft eversion anastomosis technique before its perioperative and short-term efficacy was compared with that of the vascular grafts that wrap the aortic wall and the right atrial shunt technique, providing a new basis for surgical management strategies. Method: A total of 101 patients with mildly affected AS were enrolled in the clinical trial. The extended adventitial inversion suture and the graft eversion anastomosis technique was performed in group A. Aorta wrapping and the right atrial shunt technique were performed in group B. The primary endpoints were reoperation-related events and fatal events related to the aorta, while the secondary endpoints were the duration of surgery and structural changes in the aortic root. Cardiac ultrasound and aortic computed tomography angiography examinations were performed before surgery, 2 weeks after surgery, and 1 year after surgery. Results: Compared to group B ( Conclusion: Compared with the aorta wrapping and the right atrial shunt technique, the extended adventitial inversion suture and the graft eversion anastomosis technique allow shortening of the operation time and preventing near-term dilation of the STJ, with improved safety and an improved short-term surgical effect.
