Objective To compare the improvement of clinical symptoms and patency of stents in patients with left and right non-thrombotic iliac vein compression syndrome (NIVCS) after endovascular stent therapy. Methods The clinical data of patients with NIVCS admitted to the First Affiliated Hospital of Chongqing Medical University from January 2016 to January 2021 were analyzed retrospectively. The venous clinical severity score of the patients’ veins before therapy and on month 12 after therapy was analyzed. At the same time, the patencies of stents on month 1, 3, 6, and 12 after stenting were also analyzed. Results A total of 164 patients with NIVCS were collected, including 144 left NIVCS and 20 right NIVCS. The surgical technique success rate of endovascular stent therapy was 100% (164/164). There was no statistical difference of the venous clinical severity score between the patients with left and right NIVCS on month 12 after therapy (t=1.265, P=0.208), but the venous clinical severity score of left and right NIVCS patients on month 12 after therapy were lower than those before therapy (t=27.534, P<0.001; t=10.047, P<0.001). The accumulative one-stage stent patency rate on month 12 after therapy was 96.5% and 94.7% in the patients with left and right NIVCS, respectively (χ²=0.160, P=0.689). After the stent was fully supported and completely covered the extent of the lesion, the short-term (within 12 months) stent patency rates of the patients with different compression site of the iliac vein, as well as type, diameter, and length of stent placement had no statistical differences (P>0.05). Conclusion From the results of this study, whether left NIVCS or right NIVCS, endovascular stent therapy is safe and effective.
