We have described a technique for grafting 1 mm internal diameter polytetrafluoroethylene (Gore‐Tex) to the rat femoral artery. By spatulating the ends of the recipient artery and completing the proximal anastomosis before commencing the distal one, gentle and accurate suture placement is assured. At a mean of 40 days post‐operatively (range 3542 days) 16 of 20 Gore‐Tex grafts (80%) were patent compared with 17 of 20 autogenous femoral vein grafts (85%). Examination of the prosthetic grafts by light microscopy and scanning electron microscopy showed incomplete development of a cellular lining and some areas of neo‐intimal hyperplasia. One millimetre Gore‐Tex provides excellent early patency as a microvascular graft in this experimental setting but long term patency is still undetermined.
