搭桥、分流手术中分流管端侧交接缝合处的受力分析

本文对搭桥分流术中分流管端侧交接缝合处受力进行了分析，发现分流管向的张力随分流管面积与动脉管面积的比值增大而增大，并且在流量比为０．３时该张力有最小值。夹角的影响不大，但不可忽略。考虑到缝合材料等其它因素，还需建立对缝合线密度等因素的要求。

BIOMECHANICAL ANALYSIS OF SUTURE LINE STRESS IN THE END-TO-SIDE ANASTOMOSIS

The tensile force acting on the suture line connecting a synthetic graft to a host artery in end-to-side anastomosis is shown to increase as the ratio of the graft-artery area,and has minimum value at 0.3 of the ratio of the flow rates.The angle of the end-to-side anastomosis is shown to have little effect on the suture line stress,but can not be negligated.Considering suture material and other factors,sufficient sutures per cm should be established.
