摘要：

A series of 830 mn diode laser assisted longitudinal aortorrhophy with a condition of 400 to 500 J/mm(2) for one cm lenght of anastomosis versus conventional manual anastomoses were performed in 90 Wistar rats. With comparing with normal media process, a histologic examination of aneurysm formation was conducted. The results show that there are two important factors to cause aneurysm formation after laser assisted anastomosis: 1/vessel wall is damaged by laser heating; 2/proliferation of collagen fiber at adventitia is absent when media reconstruction.
