Association of Preoperative Mean Arterial Pressure With the Primary Failure of Brescia-Cimino Arteriovenous Fistula Within the First 7 Days Following Surgery in Hemodialysis Patients.

This retrospective study included 1051 patients with end-stage kidney disease and Brescia-Cimino arteriovenous fistula (AVF) (excluding pre-dialysis patients), and aimed to investigate the role of blood pressure in AVF primary failure. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured twice daily for 3 days before surgery. The success (N = 1010) and failure (N = 41) groups were based on AVF primary failure within 7 days of surgery. The cephalic vein was larger and the preoperative mean arterial pressure (MAP) was higher in the success group compared with the failure group (P < 0.05). Cephalic vein diameter and preoperative MAP independently predicted AVF primary failure within 7 days after surgery. In conclusion, small cephalic vein diameter and low preoperative MAP were associated with AVF primary failure within 7 days of surgery.
