Abstract
Intraluminal ringed graft were utilized for surgical treatment of the 4 cases of dissecting aneurysms; typeI, type IIId, typeI with aortic insufficiency grade 4, type IIIa. All were male, and the age range was 35 to 62 years with an average age of 52. Each operation was undergone from immediafely after the onset to four and a half months after the onset. Follow-up has been from 6 to 15 months with a mean of 10 months, and all patients are alive. Aortic cross-clamp time ranged from 50 to 122 minutes with a mean of 72 minutes. The case which underwent concomitant plasty of the left coronary orifice and aortic valve replacement required 122 minutes' aortic cross-clamping. The true lumen diameters were measured by means of angiogram, CT, UCG, but their values were all larger than the actually utilized graft diameters.
