Clinical study of improved arteriovenous anastomosis and cephalic vein dilation on maturation of small vascular fistula
Objective To investigate the effect of improved arteriovenous anastomosis and cephalic vein dilation on the maturation of small intravascular fistula in end-stage renal failure hemodialysis patients.Methods A total of 43 mainte-nance hemodialysis patients with small forearm vessels admitted to the Department of Nephrology,Lianzhou People's Hospi-tal from January 2014 to April 2022 were selected as the research objects,and they were divided into observation group(n=21)and control group(n=22)by random number table method.The observation group was treated with improved arteri-ovenous anastomosis and cephalic vein dilation to establish internal fistula,while the control group was treated with tradi-tional internal fistula surgery.The diameter of cephalic vein,radial artery flow velocity,blood flow of internal fistula,the time of first use of internal fistula,the success rate of operation,the maturity rate of internal fistula,and the patency rate of 1 month and 1 year after operation were compared between the two groups.Results The diameter of cephalic vein in the ob-servation group was larger than that in the control group,the flow velocity of radial artery and the flow rate of internal fistula were higher than those in the control group,and the time of first use of internal fistula was shorter than that in the control group,and the differences were statistically significant(P＜0.05).The success rate of fistula operation,maturity rate,patency rate of 1 month and 1 year after operation in the observation group were higher than those in the control group,and the dif-ferences were statistically significant(P＜0.05).Conclusion The improved surgical method of arteriovenous anastomosis and cephalic vein expansion is beneficial to improve the success rate,maturity rate and patency rate of forearm small vascu-lar internal fistula surgery,which is worthy of clinical application.
