聚四氟乙烯小管径人工血管(Gore-Tex~R,d=3mm)移植于8例非洲猕猴腹主动脉缺损处4月后,所有服药动物(阿司匹林163mg、潘生丁25mg)的植入人工血管管腔通畅而半数对照动物植入人工血管均告阻塞。组织学检查发现,人工血管植入过程良好并有光滑新内膜形成,但吻合口邻近血管内膜则有不同程度增生。电镜检查发现,新内膜主要由成纤维 After 4 months of transplantation of polytetrafluoroethylene small diameter artificial blood vessels (Gore-Tex ~ R, d = 3mm) into the abdominal aorta defects of 8 African cynomolgus monkeys, all the animals (aspirin 163mg, dipyridamine 25mg) Lumen patency and half control animals were implanted in artificial blood vessels blocked. Histological examination found that the artificial vascular implantation process is good and smooth neointima formation, but the anastomotic adjacent to the vascular intima has varying degrees of proliferation. Electron microscopy revealed that the neointima was mainly composed of fibroblasts
