Abstract:

Objective To investigate the impact of angiography-guided puncture on the initial success rates of arteriovenous fistula （AVF） punctures in hemodialysis patients and provide clinical evidence to enhance surgical outcomes. Methods A total of 98 hemodialysis patients who underwent AVF puncture at our hospital from September 2024 to August 2025 were randomly divided into the control group and the experimental group （49 cases in each group） using the randomized digital table method. The control group received conventional puncture techniques combined with health education， whereas the experimental group underwent angiography-guided puncture. A comparative analysis was carried out on the single-puncture success rates， complication incidence， pain scores， and dialysis adequacy between the two groups. Results The experimental group attained a single-puncture success rate of 95.92%， which was significantly higher than the 79.59% success rate of the control group （P < 0.05）. The total complication rate （including hematoma， oozing， and infection） in the experimental group was 10.20%， notably lower than the 30.61% rate of the control group （P < 0.05）. The average visual analog scores （VAS） in the experimental group were （2.1 ± 0.8） points， significantly lower than the （3.8 ± 1.2） points of the control group （P < 0.05）. The urea clearance index （Kt/V） in the experimental group reached （1.45 ± 0.15）， considerably higher than the （1.32 ± 0.18） index of the control group （P < 0.05）. Conclusion Angiography-guided puncture exhibits remarkable advantages in enhancing the initial success rates of AVF puncture， minimizing complications， relieving patient pain， and improving dialysis adequacy， rendering it suitable for extensive clinical application.
