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 = bemPa was employed to fit the compliance (C)- average pressure (Pa) 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.
