摘要
探讨左肾静脉受压综合症的患儿精索静脉曲张发生率及其程度。应用彩色多普勒超声检测42例已诊断为左肾静脉受压综合症的男性患儿其不同体位时左右精索静脉的内径变化,并与左肾静脉扩张段内径(A)和受压段内径(B)比值、扩张段流速(Va)和受压段流速(Vb)比值进行比较。结果:42例患儿中平卧位和站立位无1例伴发右侧精索静脉曲张;平卧位时患儿临床型左侧精索静脉曲张占5%,亚临床型左侧精索静脉曲张占12%;站立位时临床型左侧精索静脉曲张达7%,亚临床型达21%,且随A/B比值、Va/Vb比值的增大而增加。可见左肾静脉受压时可伴发左侧精索静脉曲张,平卧位发生率为19%,站立位为28%。彩色多普勒超声是其首选的检查方法。
Frequency and degree of varicocele of spermatic veins in patients with Nut-Cracker Syndrome （NCS） are evalusted with color Doppler ultrasound. Changes in internal diameter of the spermatic veins of 42 NCS patients were detected using color Doppler sonography in different positions, and compared with the internal diameters and velocities of dilated part （A, Va） and restricted part （B, Vb） of left renal vein （LRV）. None of the patients had varicocele of right spermatic veins in supine and standing positions. In supine position, 5% of the patients had clinical varicocele and 12% had sub-clinical varicocele. In standing position, 7% had clinical varicocele and 21% had sub-clinical varicocele. Larger ratios of A/B and Va/Vb in the left renal veins indicate more serious varicocele of left spermatic veins, and varicocele of left spermatic veins may be concomitant with nut-cracker syndrome. The rate of incidence in all NCS cases is 17% in supine position and 28% in standing position, respectively. Color Doppler ultrasound can be used as the first method for detecting varicocele of left spermatic veins in NCS cases.
