Objective To investigate the clinical application of No-touch technique in the establishment of wrist standard arteriovenous fistula(SAVF) by cephalic vein separation.

Methods: The clinical data of 95 patients undergoing left or right forearm SAVF surgery to maintain long-term dialysis were analyzed retrospectively.According to the method of vein separation, 50 cases were set as No-touch technique group(group N) and 45 cases were set as traditional technique group(group T).The operation success rate, clinical success rate and complications were compared between the two groups during the follow-up period.

Results: During the follow-up period, the operation success rate in the two groups was 100.0%.The number of forearm edema cases of short-term complications in group T was significantly higher than that in group N(P < 0.01), and there was no significant difference in the number of bleeding, pain and vasospasm cases between the two groups(P>0.05).Kaplan-Meier survival analysis showed that in group N was 84.0%(42/50), which was significantly higher than 60.0%(27/45) in group T at the end of the follow-up period(P < 0.01), and Log-Rank test showed that the clinical sows nate in the clinical success rate in group N was better than group T(P < 0.05).The incidence of type Ⅰ stenosis and dysplasia of internal fistula in group N was lower than that in group T(P < 0.05), and there was no significant difference in the number of other types of stenosis, dysplasia and other cause-induced occlusion between the two groups(P>0.05).

Conclusions: It can significantly reduce the incidence of type Ⅰ stenosis and improve the clinical success rate of operation to apply No-touch technique to separate cephalic vein for SAVF establishment, which is worthy of clinical application.
