【摘要】：目的探讨慢性肾衰竭患者血管造瘘后盗血综合征的彩色多普勒超声特征。方法对87例慢性肾衰竭血管造瘘患者进行彩色多普勒超声检查,观察瘘口及距瘘口5cm内桡动脉、尺动脉和头静脉血流充盈情况及血流方向,回顾患者前臂中部头静脉血流量。结果 87例患者中,79例(79/87,90.80%)超声示桡动脉远端至瘘口处出现反向血流,其中5例(5/79,6.33%)临床诊断为盗血综合征;5例盗血综合征患者中,3例超声发现桡动脉管腔狭窄。术后1个月时79例反向血流患者前臂中部头静脉平均血流量为(481.24±84.21)ml/min,5例盗血综合征患者血流量分别为900、423、416、461和405ml/min。结论动脉狭窄及头静脉的高血流量可能为慢性肾衰竭血管造瘘患者出现盗血综合征的原因,彩色多普勒超声可为此类患者的临床诊断和治疗提供有价值的参考。
[Abstract]:Objective to investigate the color Doppler ultrasound features of steal syndrome after angiostomy in patients with chronic renal failure. Methods 87 cases of chronic renal failure angiostomy were examined by color Doppler ultrasound. The blood flow of radial artery, ulnar artery and cephalic vein were observed and the blood flow direction of the forearm central cephalic vein was reviewed. Results Seventy-nine out of 87 patients (79 / 87 / 90.80) showed reverse blood flow from distal radial artery to fistula, among which 5 cases (5 / 79 / 6.33) were clinically diagnosed as steal syndrome and 3 out of 5 patients with steal syndrome were found to have stenosis of radial artery lumen by ultrasonography. At one month after operation, the mean blood flow of forearm central cephalic vein in 79 patients with reverse flow was 481.24 卤84.21 ml / min and that in 5 patients with steal syndrome was 900423416461 ml / min and 405 ml / min, respectively. Conclusion artery stenosis and high blood flow of the cephalic vein may be the causes of steal syndrome in patients with chronic renal failure angiostomy. Color Doppler ultrasound can provide valuable reference for the clinical diagnosis and treatment of these patients.
