Abstract
|
|
|
In clinical microvascular surgery, vascular grafts 1-2 mm in diameter are often required to bridge arterial defects. Autogenous vein grafts have played a major role, but these have the disadvantages of being difficult and time-consuming to obtain, of presenting problms to flow because of the valves of the vein, and often of being unobtainable because proper diameter or sufficient length is not always available. A synthetic vascular prosthesis 2mm in diameter or less would be of great value.
This article represents the experimental results of peripheral vascular reconstruction with Goretex tubes -(expanded polytetrafluoroethylene), which have the inside diameter of 1.5mm with a wall thickness of 0.2mm and the length of 5mm.
The following results are obtained.
1)The grafts 2 days after implantation show the patency rate of 90%.
2)The grafts 7 days after implantation show the patency rate of 50%.
