摘　　要：Utilizing a reliable, reproducible arterial inversiongraft thrombosis model, comparison of intraarterial VSwith intravenous heparin delivery in maintaining micro-vascular patency has been finished, concentrated on thestudy of the effective mechanism of heparin. Vesselpatency, complication rate and representative electromi-croscopy section of the AIG were studied. Patency inthe intraarterial group is 90% (26/29) as compared to50% (12/26) in the intravenous delivery group(P【0.05).Scanning electromicroscopy showed a significant absenceof dense fibrin deposition and decrease in the numberof aggregated platelets in the intra-arterial perfusedAIG. The results of the present study indicate that thesmall dose of heparin through the artery is still effectivein maintaining the vessel pateney. Furthermore, in alarge, carefully controlled series, the complication ratewas low.Utilizing a reliable, reproducible arterial inversiongraft thrombosis model, comparison of intraarterial VSwith intravenous heparin delivery in maintaining micro-vascular patency has been finished, concentrated on thestudy of the effective mechanism of heparin.
