Diagnosis of nutcracker syndrome with color Doppler flow imaging / 医学研究生学报

ABSTRACT

Objective: To investigate the diagnose nutcracker syndrome with color Doppler flow imaging.Methods:Doppler sonographic findings in 47 children with orthostatic proteinuria or idiopathic hematuria and in 23 healthy control subjects were compared.The peak velocity,anteroposterior diameter and anteroposterior diameter ratio(hilar segment/aortomesenteric segment) were measured in the left renal vein.Results: The anteroposterior diameter ratio of the 2 segments were 4.13?2.34 in the patient group and 2.16?0.56 in the control.The anteroposterior diameter and the peak velocity in the aortomesenteric segment were(0.16?0.07)cm/s and(83.3?37.2)cm/s in the patient group and(0.24?0.09)cm/s and(43.1?10.8)cm/s in the control,with significant difference in between(P
