Embolization of the left internal spermatic vein using spring-coils was performed in 20 patients with varicocele following pressure measurement of the left renal vein and inferior vena cava. During the follow-up of 16-24 months, there was no recurrence in 16 patients with pressure difference less than 3 mmHg; however, there were two recurrences in 4 patients with pressure difference greater than 4 mmHg and opacified adrenal or ureteral veins on venography. We conclude that a significant pressure difference between left renal vein and inferior vena cava, and opacification of adrenal or ureteral veins on left renal venography may be poor prognostic signs of recurrence of varicocele following embolization.
对20例精索静脉曲张患者在测量左肾静脉和下腔静脉压力后，使用弹簧圈栓塞左精索内静脉。在16至24个月的随访中，压力差小于3 mmHg的16例患者无复发；然而，压力差大于4 mmHg且静脉造影显示肾上腺或输尿管静脉显影的4例患者中有2例复发。我们得出结论，左肾静脉与下腔静脉之间存在显著压力差，以及左肾静脉造影显示肾上腺或输尿管静脉显影，可能是精索静脉曲张栓塞术后复发的不良预后征象。
