Abstract:
Objective To explore the diagnostic value of brachial artery vascular ultrasound inspection for autologous arteriovenous fistula (AVF) complications.
Methods Retrospective analysis of ultrasound imaging data was applied to 106 patients with chronic kidney disease undergoing AVF in the Ultrasonic Department of Drum Tower Hospital Affiliated to Medical School of Nanjing University from March 2016 to June 2020. Patients were divided into non-complication group (n=57) and common complication group (n=49) according to ultrasound examination results. The latter was further divided into cephalic venous thrombosis group (n=8), cephalic venous stenosis group (n=31) and cephalic venous aneurysm-like dilatation group (n=21), according to the type of complications, 10 patients had two or more complications. The diameter, peak systolic velocity (PSV), end-diastolic velocity (EDV), resistance index (RI), time-averaged mean velocity (TAMV), pulsatility index (PI), and blood flow of brachial artery were measured by ultrasound. The parameters of brachial artery were compared between groups, and the diagnostic value for cephalic vein stenosis was analyzed by receiver operating characteristic(ROC)curve.
Results The PSV[(149.42±41.95)cm/s], EDV[(71.75±23.62)cm/s], TAMV[(59.25±19.79)cm/s], blood flow [(898.26±357.09)ml/min] of brachial artery in non-complication group were higher than those of common complication group[(128.91±40.42)cm/s, (56.19±29.98)cm/s, (46.82±23.69)cm/s, 659.00(291.50, 934.50)ml/min], with significant differences (t=2.55, 2.98, 2.94, Z=-2.60, all P<0.05). PI[1.38(1.13, 1.61)] in non-complication group was lower than that of the common complication group [1.52(1.11, 2.40)], with significant difference (Z=2.13, P<0.05). The areas under the ROC curve of brachial artery diameter, PSV, EDV, RI, PI, TAMV and blood flow for the diagnosis of cephalic venous stenosis were 0.71, 0.73, 0.76, 0.70, 0.68, 0.75, 0.81. Specificities were 68.42%, 75.44%, 91.23%, 89.47%, 92.98%, 92.98%, 91.23%, while sensibilities were 67.74%, 64.52%, 54.84%, 48.39%, 51.61%, 54.84%, 61.29% (all P<0.01).
Conclusion Ultrasound monitoring of brachial artery vascular parameters has certain diagnostic value for AVF complications, and the brachial artery flow has the greatest diagnostic value for cephalic venous stenosis.
