Aortic dissection is a rare but fatal condition, and early diagnosis and treatment are critical. Acute aortic dissection, if left untreated, increases mortality by about 1% per hour within 48 hours of onset, and 70% of patients die within the first week. The Stanford classification divides aortic dissection into type A and type B, with type A involving the ascending aorta and type B not. The primary goals of the Stanford Type A ascending aortic dissection emergency surgical intervention are to prevent aortic rupture, treat aortic insufficiency, and save lives by directing blood flow to the branching vessels of the dissection. Optimal treatment of type A acute aortic dissection remains a formidable challenge for cardiovascular surgeons. Despite these advances, the mortality rate for routine aortic dissection remains between 10% and 27%. Today, open surgery is still important in terms of treatment and has achieved satisfactory results.
In the surgical treatment of aortic dissection, many patients currently use dacron graft insertion and anastomotic line dissection techniques. In the English literature, intercalation techniques typically use Teflon strips and bioglue to stop bleeding and form tighter woven sutures. In the surgical treatment of ascending aorta dissection, we used Teflon and polyester graft strips as surgical materials to establish a stronger anastomotic suture and help the anastomotic hemostasis. Mortality and morbidity were compared for patients grouped according to these two different materials. Evaluate the results.
