title: A new vascular ring connector in surgery for aortic dissection.
abstract: OBJECTIVE
  To improve the surgical results of aortic dissection, we used a novel vascular ring connector for anastomosis.
  
  
  METHODS
  The vascular ring connector is a titanic ring used as a stent in the vascular graft to achieve a quick, blood-sealed, and sutureless anastomosis. From November 2007 to December 2008, 19 consecutive patients (age range 36-77 years; 16 male and 3 female) with aortic dissection underwent open surgery. All patients received aortic reconstruction with vascular grafts (including 5 cases of arch replacement). The combined procedures were 5 Bentall and 4 coronary artery bypass graft operations.
  
  
  RESULTS
  There were no significant blood leaks from the anastomotic sites. The time required for each anastomosis was 1 to 2 minutes. All patients were discharged uneventfully and are still doing well after a follow-up period of 1 to 12 months.
  
  
  CONCLUSIONS
  The vascular ring connector may improve the early surgical results of aortic dissection by reducing both the time for anastomosis and the risk of bleeding and may be an alternative technique for aortic reconstruction. Its usefulness in the routine treatment of aortic dissection warrants further evaluation.
