REPLACEMENT OF PROSTHETIC VASCULAR GRAFT TO SEVERELY DAMAGED AORTIC LESIONS
6. Experiences in dissecting aneurysm of the aorta (type Ⅲb) with a special reference to reinforcement technique of the anastomoses

Surgical repair of dissecting aneurysm of the aorta is said difficult due to the nature of fragile and torn aortic wall which is likely to lead to anastomotic insufficiency. The dissecting process may be confined to the thoracic aorta distally (type Illa) and the lesion can be repaired by total replacement of the graft. But the process often extends into the abdominal aorta (type IIIb) and in these circumstances total replacement is not feasible. Partial replacement of the fusiform like dilatation of the aorta is usually performed. At that time anastomotic technique should be meticulous. The authors usually apply reinforcement technique including internal pledget and external sheet support, wrapping with a fine mesh and prevention of dilatation with Dacron tube collar. The technique is shown in the film presentation.
