Abstract:
Objective To study the success experience of native arteriovenous fistula (AVF) operation,and provide a new reference range of blood vessel diameter for evaluating the success rate of AVF operation before surgery.Methods To proceed AVF operation to patients with 5 phase of chronic kidney disease,before surgery,patients should receive the vascular ultrasound and cardiac ultrasound to record the diameter of radio artery and cephalic vein along with the radio artery blood flow.Patients were divided into two groups:observation group(cephalic vein diameter< 2 mm)and control group(cephalic vein diameter > 2.0 mm). All those indexes examined before were re-examined 1 month after surgery. Except vessel diameter, the AVF blood flow velocity was also recorded. The range of the mature period was measured, along with the blood flow of each AVF 1 month after its initial use. The blood vessel diameter before surgery,the mature period of AVF and the blood flow on the machine of dialysis 1 month after the initial use were measured to evaluate the operation results of each group. Results In the observation group, 23 of the 25 patients showed the optimistic results. Unfortunately, 1 of the 2 pessimistic results showed the absence of vascular murmur,and the other one died of natural death before its initial use.The mature period of AVF for hemodialysis was(47.29 ± 2.45)d,significantly longer than that of control group (36.00 ± 1.29) d, and there was statistical difference (P<0.01). The blood flow of observation group showed no significant difference compared to that of control group (P > 0.05). Conclusions The patients with cephalic vein diameter<2.0 mm before operation needs a long mature period,but the blood flow after dialysis is not affected,and a good success rate is obtained.
