O018 Determining the relationships between venous reflux patterns, clinical severity, and health-related quality of life

Abstract

Abstract Introduction Various classification systems have been created to describe the anatomical distribution of venous reflux, including the VEIN-TERM and Clinical-Etiology-Anatomy-Pathophysiology (CEAP) classification. It is still unclear whether different reflux patterns correlate with health-related quality of life (HRQoL) and clinical severity. Methods Some 507 chronic venous disease patients and 105 asymptomatic controls underwent duplex ultrasound assessment. Patients were stratified according to VEIN-TERM and the CEAP classification systems. The Aberdeen Varicose Vein Questionnaire (AVVQ) score was used to compare HRQoL and the Venous Clinical Severity Score (VCSS) was used to compare clinical severity between groups. Results Patients were significantly older than controls (p<0.00001). All VEIN-TERM reflux patterns had significantly greater VCSS than no reflux (p<0.001). Superficial axial and combined axial reflux were associated with significantly greater VCSS than superficial segmental reflux (p<0.001, p=0.042 respectively). All VEIN-TERM reflux types had significantly worse AVVQ scores than no reflux (p<0.03). However, there were no significant differences in AVVQ scores across all VEIN-TERM reflux patterns. Most CEAP reflux patterns had increased VCSS and worse AVVQ scores when compared to no reflux (all p<0.05), except for deep reflux, and deep and perforator reflux only. The deep, superficial and perforator reflux group had significantly higher VCSS (p=0.013) and AVVQ (p<0.001) versus the superficial reflux only group. Conclusion When compared to no reflux, both classification systems show associations of any reflux pattern with worse VCSS and AVVQ scores. Combined reflux patterns were associated with the greatest clinical severity and worst HRQoL scores.
