目的：研究左肾静脉解剖走向，探讨左侧精索静脉曲张栓塞治疗最佳路径。材料与方法：对30例下腔静脉、左肾静脉及左侧精索静脉（SV）造影作回顾性分析，测量左肾静脉与下腔静脉之间的夹角，SV在肾静脉内开口与下院静脉侧缘的距离，并对经皮右锁骨下静脉穿刺上腔静脉入路行SV栓塞与经股静脉穿刺下腔静脉入路进行比较。结果：左肾静脉与下院静脉之间夹角为47°～86°，经上腔静脉入路栓塞SV的平均时间为20min，曝光时间为5min；下腔静脉入路手术平均时间110min，曝光时间为46min。结论：从上腔静脉入路栓塞SV的平均时间明显缩短，成功率高，说明从上腔静脉入路为最佳。
Objective: To study the anatomic trend of the left renal vein and to explore the optimal path of left varicocele embolization. Materials and Methods: Thirty cases of inferior vena cava, left renal vein and left spermatic vein (SV) were retrospectively analyzed. The angle between the left renal vein and the inferior vena cava was measured. The opening of SV in the renal vein Lower limb venous lateral margin distance, and percutaneous right subclavian vein puncture superior vena cava SV embolization through the femoral vein puncture inferior vena cava for comparison. Results: The angle between left renal vein and lower ventricle vein was 47 ° ~ 86 °. The average time for SV embolization via superior vena cava was 20 minutes and the exposure time was 5 minutes. The average time of inferior vena cava venous approach was 110 minutes. The exposure time For 46min. CONCLUSION: The mean time to SV embolization from the superior vena cava is significantly shortened and the success rate is high, which shows that the superior vena cava approach is the best.
