Effectiveness of iliac vein stenting combined with high ligation/endovenous laser treatment of the great saphenous veins in patients with Clinical, Etiology, Anatomy, Pathophysiology class 4 to 6 chronic venous disease.

Abstract Background Lower limb chronic venous disease (CVD), resulting from iliac vein compression syndrome (IVCS), manifests as a series of symptoms ranging from varicose veins to venous ulcerations. Stent implantation has been considered an effective treatment method; however, the management of CVD has rarely been reported. In the present study, we evaluated the treatment and outcomes of patients with CVD. Methods We performed a retrospective cohort study of patients with severe iliac vein stenosis with lower limb CVD. The patients were divided into two groups: group 1 had received stenting alone (n = 42), and group 2 had received stenting and high ligation/endovenous laser treatment (n = 29). We evaluated the clinical outcomes using the Venous Clinical Severity Score and visual analog scale, and assessed the quality of life (QoL) using the Chronic Venous Disease QoL questionnaire at a median follow-up point of 15 months (range, 6-25 months). Results In our cohort, the prevalence rate of nonthrombotic IVCS (NIVCS) was 11.7% (98 of 838 patients). The technical success rate was 100%, without severe complications. During the study period, three group 1 patients and two group 2 patients were lost to follow-up. The overall patency rate in the patients with NIVCS during a mean follow-up period of 15.0 months (range, 6-25 months) was 94.4%. For patients with a Clinical, Etiology, Anatomy, Pathophysiology (CEAP) clinical class of  Conclusions The prevalence of NIVCS should not be overlooked. The proposed combination treatment is an effective therapeutic strategy for patients with NIVCS and advanced CVD (CEAP clinical class, ≥4) during short-term follow-up.
