Objective To modify the method for aortic end strengthening in acute type A aortic dissection operation, and investigate its clinical efficacy. Methods We modified the method for aortic end strengthening in acute aortic dissection operation based on ‘Sandwich method’ in the department of thoracic and cardiovascular surgery of West China Hospital. From January 2006 to December 2008, twentyeight patients with acute type A aortic dissection underwent modified aortic end strengthening operation. We made adventitia turn over and enfold to strengthen the aortic end in 10 cases, and placed stripshaped felt or pericardium belts between dissection (between adventitia and intima)and inner intima and strengthened the aortic end by suture in 18 cases. The hemorrhage of anastomotic stoma and the postoperative early prognosis were observed. Results No bleeding complication was found in all the cases. Two cases died, one died of severe low cardiac output syndrome and another died of multiple organ failure. No nervous system complication was found except that 2 cases had delayed revival. No sternum and surgical incision related complication was found. The rest 26 cases were cured and discharged. Conclusion The modified method for aortic end strengthening can not only strengthen the aortic end but also make people be able to find the petechia of anastomotic stoma clearly, then stitch hemostasia could be done effectively. The method is easy to implement and effective, it should be extend in clinic.
