Segmental microvenous graft to artery.
One hundred and five microvenous grafts were carried out during three periods of time. Forty-five were performed in 1971, 25 were performed in 1975 and 35 were performed in 1979. The rabbits weighed 2 to 2.5 kg and a standard technique was followed by inserting a 1 cm vein graft after creating a defect of 0.5 cm in the femoral artery, taking the graft from the femoral vein on the same side. Exploration was carried out from 1 to 21 weeks at weekly intervals. The patency rate in Series I (1971) was 71 per cent, whereas the patency rate in Series II (1975) was 96 per cent and in Series III (1979) was 100 per cent. The scanning electron microscope showed that in the short term there was no narrowing of the lumen, nor any microaneurysm formation as reported previously by Buchler and Buncke (1979).
