Objective To explore the value of Caprini thrombosis risk assessment scale for the prediction of thrombosis events and primary patency rate within 6 months after arteriovenous graft (AVG) surgery in hemodialysis patients. Method A retrospective study was conducted on patients with end-stage renal disease and subjected to AVG surgery from October 2017 to January 2023. General information, surgical data and postoperative patency within 6 months were collected. Patients were divided by professional nurses into group A (low risk patients), group B (medium risk patients), and group C (high and extremely high risk patients) based on the Caprini score during hospitalization. General and intraoperative data were compared among the three groups. Kaplan-Meier survival curve was used to analyze the patency rate within 6 months after surgery in the three groups of patients. COX model was used to analyze the related risk factors. Result A total of 52 patients were recruited in this study, including 30 males and 22 females and with the average age of 54.75±12.68 years old. Age(Z=5.836, P=0.005),D-dimer (Z=4.009, P=0.024),hospitalization day(Z=4.432,P=0.017) and follow-up period (Z=7.155, P=0.002) were statistically different but patency rate within 6 months after the surgery (χ2=1.851, P=0.396) had no difference among the three groups. COX regression demonstrated that age (OR=1.015, 95% CI: 0.943～1.092, P=0.695), hospitalization day (OR=0.970, 95% CI: 0.743～1.265, P=0.820), D-dimer (OR=1.029, 95% CI: 0.594～1.782, P=0.920), and Caprini score (OR=1.969, 95% CI: 0.270～14.367, P=0.504) were not related to postoperative primary patency rate. Conclusion The Caprini thrombosis risk assessment scale may lack the objective clinical evidence for evaluating thrombosis events in patients with end-stage renal disease after AVG surgery.
