The patency rates of arterial grafts preserved by immersion in 70% alcohol and arterial grafts preserved by ficin digestion and dialdehyde tanning were compared with the patency rate of fresh autogenous vein grafts in 5-mm defects in the femoral arteries of 50 rats. The overall patency rate for the fresh vein grafts was 90%. The patency rate at 2 weeks for the alcohol-preserved arterial grafts was 40%; the patency rate for the dialdehyde-tanned arterial grafts at 2 weeks was 30%. The difference between the rates for the fresh vein grafts and the alcohol-preserved and dialdehyde-tanned grafts was statistically significant (P less than 0.01 and P less than 0.001, respectively). At 2 months there was no statistically significant difference in the rates between the autogenous vein grafts and the preserved arterial grafts, probably because of recanalization of grafts that had occluded primarily. From the data, it is concluded that fresh autogenous vein grafts are still superior to preserved arterial grafts in microvascular surgery.
将50只大鼠股动脉5毫米缺损处用70%酒精浸泡保存的动脉移植物、用 ficin消化和双醛鞣制保存的动脉移植物的通畅率与新鲜自体静脉移植物的通畅率进行比较。新鲜静脉移植物的总体通畅率为90%。酒精保存的动脉移植物在2周时的通畅率为40%；双醛鞣制的动脉移植物在2周时的通畅率为30%。新鲜静脉移植物与酒精保存及双醛鞣制移植物的通畅率差异具有统计学意义（分别为P<0.01和P<0.001）。在2个月时，自体静脉移植物与保存的动脉移植物的通畅率无统计学显著差异，这可能是由于最初闭塞的移植物再通所致。从这些数据可以得出结论，在微血管手术中，新鲜自体静脉移植物仍优于保存的动脉移植物。
