Characters and influential factors of vascular remolding after native arteriovenous fistula / 中华肾脏病杂志

ABSTRACT

Objective To finding out the characters of vascular remolding after the establishment of native arteriovenous fistula on the wrist,and exploring the influential factors.Methods Doppler ultrasound was used to monitor the diameter of cephalic vein,brachial artery,radial artery and ulnar artery at the time before the surgery and one day,one week,two weeks,four weeks and eight weeks after the surgery respectively.The tendency of the diameter change was analyzed.Results Twenty eight patients completed the whole monitor session,in which eleven were female.The average age of those patients was (53.68 ± 2.61) years old.Twelve of them were diabetic nephropathy.The diameters of all vessel were increased more rapidly at the first day than any other days after surgery(all P ＜ 0.01).The patients were divided into two groups depending on whether diabetic nephropathy.No significant difference was found between the two groups on the tendency of diameter change in cephalic vein and brachial artery (all P ＞ 0.05).However,the tendency of diameter change in radial artery and ulnar artery was statistically significant difference between the two groups (all P ＜ 0.05).Conclusions Cephalic vein,brachial artery,radial artery and ulnar artery are all apparently dilated on the first day after the surgery.The vascular dilation and diameter increasing become much slower after the period,the diameter tend to be stable.The primary diseases may affect the tendency of the diameter change in radial artery as well as ulnar artery.
