Abstract:
Objective To investigate the clinical and imaging features of right-side non-thrombotic iliac vein compression syndrome(NIVCS),and to evaluate the efficacy of endovascular treatment.Methods The clinical data and imaging materials of lower extremity venography from January 2019 to February 2024 in Affiliated Nanjing Gaochun People's Hospital,Jiangsu University were retrospectively analyzed.The patients with clinically diagnosed right-side NIVCS who received endovascular treatment were selected for this study.The clinical features and imaging findings,technical success rate,postoperative clinical improvement,and stent patency rate were analyzed.Results The median follow-up time was 30.2 months(3-58 months).A total of 24 patients with right-side NIVCS(aged 42-73 years)were enrolled in this study.Of the 24 patients,22(91.7％)were male and only 2(8.3％)were female,the proportion of male was significantly higher than that of female(P＜0.001).According to Clinical Etiologic Anatomic Pathophysiologic(CEAP)grading,14 patients were of grade C3,9 patients were of grade C,and one patient was of grade C.Imaging examination showed that the most frequent site of compression was the proximal end of the external iliac vein(15/24,62.5％),the second frequent site of compression was the proximal part of the common iliac vein bifurcation(5/24,20.8％).The most common external pressure structure was the internal and external iliac arteries(14/24,58.3％),the second common external pressure structure was external iliac artery and sacrum(5/24,20.8％).The technical success rate was 100％,and only one stent was implanted in each patient(diameter of 12-14 mm and length of 80-90 mm).The most commonly used stent was the Smart control(19/24,79.2％).During follow-up period,the remission rate of edema was 85.7％(18/21),the ulcer healing rate was 100％(1/1),and all stents remained patent.Conclusion Right-side NIVCS is more commonly seen in male patients.Because the compression site is usually located at the distal end of iliac vein,thus,the implanted stent may rarely affect blood flow in the contralateral iliac vein.Therefore,endovascular treatment is a safe and effective method for right-side NIVCS.
