目的：研究左肾静脉走向，探讨左侧精索静脉曲张栓塞治疗最佳路径。方法：对４５例下腔静脉、左肾静脉及左侧精索静脉（ＳＶ）造影的患者，测量左肾静脉与下腔静脉之间的夹角，ＳＶ在肾静脉内口与下腔静脉侧缘的距离，并对经皮右锁骨下静脉穿刺上腔入路行ＳＶ栓塞与经股静脉穿刺下腔入路进行比较。结果：左肾静脉与下腔静脉之间的夹角为４７°～８６°，ＳＶ于左肾静脉内开口与下腔静脉侧缘的最小距离为２５～６２ｍｍ。上腔路径组平均手术时间２０ｍｉｎ，曝光时间５ｍｉｎ；下腔路径组平均手术时间１１０ｍｉｎ，曝光时间４６ｍｉｎ。结论：从上腔静脉入路栓塞ＳＶ的平均时间明显缩短，说明从上腔静脉入路为最佳
Objective: To study the left renal vein to explore the best path of left varicocele embolization. Methods: In 45 patients with inferior vena cava, left renal vein and left spermatic vein (SV) imaging, the angle between the left renal vein and the inferior vena cava was measured. SV was measured between the internal veins of the renal vein and the inferior vena cava Edge distance, and the percutaneous right subclavian vein puncture on the superior vena cava SV embolization and transvenous puncture inferior vena cava were compared. Results: The angle between left renal vein and inferior vena cava was 47 ° ~ 86 °. The minimum SV distance between the opening of left renal vein and lateral margin of inferior vena cava was 25 ~ 62mm. The average operation time of the superior vena cava group was 20 minutes and the exposure time was 5 minutes. The mean operative time of the inferior vena cava group was 110 minutes and the exposure time was 46 minutes. CONCLUSIONS: The mean time to SV embolization from the superior vena cava was significantly shorter, indicating that the superior vena cava approach is the best
