Abstract: 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.
