RESUMO
Objective To evaluate the clinical value of the condition of radial artery for autogenous arteriovenous fistula ostomy by color Doppler ultrasound. Methods The condition of radial artery of 133 end-stage renal disease( ESRD) patients who received autogenous arteri-ovenous fistula ostomy were detected by color Doppler ultrasound,and compared with the postoperative parameters of fistula vascular. Results Among all 133patients,the preoperative radial artery of 95 cases were normal,abnormal in 38 cases. Ostomy surgery performed on 131 cases. Two cases gave up surgery for the poor condition of radial artery,13 cases with fistula failure. The success rate with normal radial artery (95. 8%) was higher than that with the abnormal radial artery(75%). The blood flow parameters of normal radial artery were significantly better than those of the abnormal radial artery,and 4 weeks after operation,the anastomotic blood flow and blood vessel diameter were better than those 1 week before and after surgery. Conclusion Color Doppler ultrasound that can provide preoperative data of radial artery, predict postoperative the state of fistula vascular,and monitor the conditions of postoperative fistula vascular,with better clinical value.
