| 摘 要： | 通过在体测定狗股动脉非吻合、正常吻合及张力吻合后不同时相点吻合口段的压力与直径相应的数据 ,计算出动脉非吻合、正常及张力吻合后的顺应性 ,顺应性与平均血压曲线用幂函数 C=bem Pa进行拟合 ,建立顺应性与平均血压的关系。结果表明 :在各时相点 ,吻合组的顺应性低于非吻合组 ,张力吻合组吻合口段动脉的顺应性低于正常吻合组 ,术后 14 d降低最显著。反映出动脉张力吻合术后近期吻合口段的可扩张能力较正常吻合动脉及正常动脉有明显减弱。张力吻合对吻合口段动脉的功能有较大影响

| Abstract: | The data of arterial pressure and diameter were measured in vivo before and after normal anastomosis and tensional anastomosis in canine femoral arteries at different time intervals. The arterial compliance was calculated, and the exponential form C=be mPa was employed to fit the compliance (C) average pressure (P a) curve. The relationship between compliance and average pressure was determined. The results showed that the compliance of arteries decreased after anastomosis, and the compliance of arteries after tensional anastomosis was lower than that of normal anastomosis at different time intervals. It was decreased most markedly at 14 days after tensional anastomosis. This indicated that the distensibility of tensional anastomotic artery was decreased more markedly than that of normal anastomotic artery. The function of artery was evidently affected by tensional anastomosis. |
