摘要：

Objective: Compliance and formation of distal anstomotic intimal hyperplasia (DAIH) were investigated in externally stiffened venous grafts of varying calibers. Methods: 36 femoropopliteal reconstructions were performed in 18 sheep. The autologous venous grafts were inserted into tubes made of Dacron mesh to achieve compliance-mismatch and lumen adaptation Compliance tons measured by echo-tracked ultrasonography and profiles of DAIH were generated from histologic sections harvested after 8.3 months. Main results: The external mesh tube significantly lowered the local compliance of graft and host artery. DAIH appeared extensively in those groups where mesh tube constricted venous grafts met untreated host arteries (p = 0.002). No differences in compliance and DAIH formation were observed when grafts with large and adapted diameters were compared. Conclusions: For prevention of DAIH the distal venous graft diameter is not important, while the local compliance of an autologous vein is a predictive factor for DAIH formation and thus long-term patency.
