Abstract:
Objective To investigate the effect of vascular inner diameter and artery flow velocity on the flow of internal arteriovenous fistula. Methods Sixty-two patients received the operation of internal fistula were enrolled. According to the inner diameter (Group A: d ≤ 1.5 mm, Group B: 1.5 mm < d ≤ 2.0 mm, Group C: 2.0 mm < d ≤ 3.0 mm, Group D: d > 3.0 mm), the patients were divided into four groups in terms of artery flow velocity (Group a: v ≤ 20 cm/s, Group b:20 cm/s < v≤50 cm/s, Group c:50 cm/s < v ≤ 100 cm/s, Group d:v > 100 cm/s), the differences of fistula and dialysis flow for two months were analyzed among various groups. Results Compared with Group B/b, patients in Group A/a had higher risk of operation failure, with lowered inner fistula flow and dialysis flow. In terms of inner venous diameter , there were significant differences between Group B and C. Conclusions It is not recommended to carry out the inner vascular fistula operation. Followed with the thickening and increasing of inner artery diameter and artery flow , the inner fistula flow and the dialysis flow increase. The inner venous diameter has no significant impact on the inner fistula flow.
