Background: Arteriovenous (AV) shunt creation is the preferred vascular access for patients undergoing long-term hemodialysis. The success of AV shunt procedures is influenced by various patient-related and procedural factors. Understanding these predictors is important to improve clinical outcomes and optimize surgical planning.
Objective: This study aimed to identify predictive factors affecting the success of radial arteriovenous shunt creation at Sardjito Hospital, Yogyakarta.
Methods: This study employed an observational analytic design with a retrospective approach. Medical records of patients who underwent radial AV shunt surgery at Sardjito Hospital were analyzed. Variables evaluated included patient age, sex, diabetes mellitus status, hypertension, surgeon experience, preoperative ultrasound examination, and postoperative management. The outcome variable was the success of the AV shunt procedure. Statistical analysis included bivariate and multivariate analyses to identify independent predictors of AV shunt success.
Results: The success rate of radial AV shunt creation at Sardjito Hospital was 80.9%, indicating that the procedure was performed effectively both in surgical technique and perioperative management. Patient age was not significantly associated with AV shunt success. However, patient sex showed a significant relationship with procedural success, with male patients demonstrating a higher likelihood of successful outcomes compared to female patients. Diabetes mellitus and hypertension were not significantly associated with AV shunt success. Surgeon experience emerged as the most influential predictive factor, with more experienced surgeons significantly increasing the probability of successful AV shunt creation. Preoperative ultrasound examination and postoperative management did not show statistically significant associations with AV shunt success, although they remain clinically important in surgical planning and patient safety. Multivariate analysis demonstrated that patient sex and surgeon experience were independent predictors of radial AV shunt success.
Conclusion: The success rate of radial AV shunt procedures at Sardjito Hospital is high. Patient sex and surgeon experience are independent predictors of procedural success, while age, diabetes mellitus, hypertension, preoperative ultrasound, and postoperative management were not statistically significant predictors. Emphasis on surgical expertise and appropriate patient selection may further improve clinical outcomes.
