彩超对“胡桃夹”综合征的诊断价值探讨

Diagnostic Value on Nut Cracker Syndrome with Color Doppler Ultrasound

目的:探讨彩超诊断"胡桃夹综合症"的价值。方法:采用平卧位、直立位、蹲位、右侧屈膝位分析10例"胡桃夹"综合征的左肾静脉远端和近端血管内径及流速。结果:平卧位、蹲位、右侧屈膝卧位与直立位比较差异有统计学意义。采用平卧位、蹲位、右侧屈膝卧位可以使左肾静脉远心端内径(b)/近心端内径(a)减小,Va/Vb减小。结论:彩超对观察"胡桃夹"综合征不同体位左肾静脉内径及血流改变具有显著的临床价值。

Objective： To investigate the value of color Methods： To measure the diameter and blood flow velocity Doppler ultrasound in diagnosis of Nut Cracker syndrome. of the distal and proximal left renal vein at supine position, upright position, kneeling-squatting position and dorsal recumbent position. Results： There is significant difference among different positions. Compare with upright position, the ratios of diameter of distal left renal vein diameter/proximal left renal vien and blood flow velocity of distal left renal vein diameter/proximal left renal vien are smaller at supine position, kneeling-squatting position and dorsal recumbent position. Conclusions： Color Doppler ultrasound has significant clinical value for observing changes of diameter and blood flow of left renal vein at different position.
