Abstract
BackgroundLower 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. MethodsWe 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). ResultsIn 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 <4, all parameters showed similar improvements in the two groups, except for the disappearance of varicose veins. However, in patients with a CEAP clinical class of ≥4, the combination therapy significantly improved their QoL. The Venous Clinical Severity Score reduction was 4.64 ± 1.72 in group 1 and 11.89 ± 1.82 in group 2 (P < .01). Pain, scored using the visual analog scale, demonstrated a decrease from 4.41 to 2.52 (P < .05) in group 1 and 4.71 to 0.53 (P < .01) in group 2. The relief rate of stasis dermatitis in groups 1 and 2 was 26.9% and 90.5%, respectively (P < .05), and the venous ulceration healing rate was 16.7% and 87.5%, respectively (P < .05). ConclusionsThe 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.
