Effect of different surgical methods in the treatment of arteriovenous fistula on cardiac function in hemodialysis patients

Objective:To investigate the effects of different surgical methods in the treatment of arteriovenous fistula on cardiac function in hemodialysis patients.Methods:Sixty uremic patients were treated with end-to-end arteriovenous fistula anastomosis(30 cases) and end-to-side arteriovenous fistula anastomosis(30 cases).The arteriovenous fistula and heart function in all patients were observed,and the effects of different surgical methods on cardiac function were evaluated.Results:The postoperative average blood flow and diameter in end-to-side anastomosis group were higher than those in end-to-end anastomosis group(P<0.01).After 1 year of operation,the cardiac index significantly increased,and the ejection fraction significantly decreased in end-to-side anastomosis group,and the differences of the cardiac index and ejection fraction between two groups were statistically significant(P<0.01).The difference of the incidence rate of the fistula failure between two groups was not statistically significant(P>0.05).Conclusions:The end-to-side anastomosis in the treatment of arteriovenous fistula in hemodialysis patients can ensure the blood flow,does not increase the heart load,which is worthy of promotion.
