目的 探讨Venovo髂股静脉支架用于血液透析患者左无名静脉病变的有效性和安全性。 方法 回顾性分析上海中医药大学附属龙华医院2023年3月─2024年5月收治的10例植入Venovo髂股静脉支架治疗左无名静脉病变患者的临床资料。 结果 10例患者手术前胸部CT显示左无名静脉最狭窄处平均直径为(3.09±2.31)mm[(0～5.9)mm]，静脉造影证实3例左无名静脉闭塞；5例无名静脉汇入上腔静脉处狭窄，2例无名静脉水平段狭窄。植入支架后显示支架最狭窄处平均直径(10.80±1.00)mm[(9.89～12.68)mm]。平均随访时间(7.76±4.4)月，6个月初级通畅率为100%，所有患者临床症状均未复发。 结论 Venovo髂股静脉支架具有良好的支撑力和柔顺性，可纠正解剖压迫引起的左无名静脉病变，其远期效果有待进一步观察。
Objective To investigate the efficacy and safety of Venovo venous stent for the treatment of left innominate vein stenosis in hemodialysis patients. Method Clinical data of the 10 patients treated with implanted Venovo venous stent for left innominate vein stenosis in Longhua Hospital of Shanghai University of TCM from March 2023 to May 2024 were retrospectively analyzed. Results Preoperative chest CT of the 10 patients showed that the average diameter of the narrowest part of the left innominate vein was 3.09±2.31 (0～5.9) mm. Venography confirmed that the left innominate vein was occluded in 3 cases; the innominate vein was narrowed at the confluence of the superior vena cava in 5 cases, and the horizontal segment of the innominate vein was narrowed in 2 cases. After stent implantation, a mean diameter of 10.80±1.0 (9.89～12.68) mm was found at the narrowest part of the stent. The follow-up period was 1～15 months, with a mean of 7.76±4.4 months. The primary patency rate at 6 months was 100%. None of the patients showed relapse of the clinical symptoms. Conclusion Venovo venous stent as a better supporter with a proper flexibility successfully corrected left innominate vein lesions from anatomical compression. However, further observation is required for its long-term effect.
