OBJECTIVES
Aneurysm formation in Human Umbilical Vein Grafts has been reported to be as high as 65% after 5 years. One of the causes might be the structure of the Biograft-wall and in 1985 a new method of processing the graft was begun. In Groningen this new improved Biograft has been used since late 1986.
DESIGN
Duplex scanning was used to examine the frequency of aneurysm formation in the new improved Biograft.
MATERIALS
Sixty-nine patent Biografts have been examined in a period up to 6 years after implantation.
MAIN RESULTS
Aneurysms were found in only 17% of grafts although the frequency increased with time. Dilatation was common but may be due to a more elastic graft.
CONCLUSION
These findings justify the continued use of the new Biograft as a substitute for arterial femoropopliteal reconstructions.
目的
据报道，人脐静脉移植物中动脉瘤形成在5年后高达65%。原因之一可能是生物移植物壁的结构，1985年开始了一种新的移植物处理方法。自1986年末起，在格罗宁根使用了这种新改良的生物移植物。
设计
采用双功扫描检查新改良生物移植物中动脉瘤形成的频率。
材料
在植入后长达6年的时间里，对69个通畅的生物移植物进行了检查。
主要结果
仅在17%的移植物中发现动脉瘤，尽管其频率随时间增加。扩张很常见，但可能是由于移植物更具弹性。
结论
这些发现证明继续使用新生物移植物替代股腘动脉重建是合理的。
