A study to compare disease-specific quality of life with clinical anatomical and hemodynamic assessments in patients with varicose veins.

The wide variety of outcome measures to evaluate patients with varicose veins poses significant difficulties when comparing clinical trials. In addition, the relationship between different outcome measures is poorly understood. The aim of this study was to compare anatomical, hemodynamic, and clinical outcomes with disease-specific quality-of-life tools in patients undergoing treatment for varicose veins. Patients undergoing treatment for symptomatic veins in a single unit were studied. Assessments included duplex ultrasonography, digital photoplethysmography, evaluation of Venous Clinical Severity Scores and CEAP scores, generic (Short Form 12 [SF12]) and disease-specific (Aberdeen Varicose Vein Questionnaire [AVVQ], and Specific Quality-of-life and Outcome Response-Venous [SQOR-V]) questionnaires. Patients were reviewed at 6 weeks when hemodynamic, clinical, and quality-of-life assessments were repeated. The relationships between these outcomes were assessed. The AVVQ showed a strong positive correlation with the SQOR-V (Spearman coefficient 0.702; P < .001) and weaker, but significant correlations with the SF12 physical and mental component scores and the Venous Clinical Severity Score (VCSS) (P < .001, P = .019, and P < .001, respectively, Spearman correlation). No correlations were observed between the AVVQ and photoplethysmography results (Spearman coefficient -0.042; P = .606), and weak correlations were observed with the AVVQ and anatomical reflux. At 6 weeks, functional, clinical, and hemodynamic measurements were all responsive to changes following interventions; however, correlations observed between changes in disease-specific quality-of-life and generic, clinical, and hemodynamic outcomes were weak. Both the AVVQ and SQOR-V questionnaire are sensitive and responsive disease-specific questionnaires, which correlate with generic and clinical outcomes to some extent. Anatomical and hemodynamic measurements correlated poorly with functional outcomes both preoperatively and following interventions.

Prospective randomized trial comparing endovenous laser ablation and surgery for treatment of primary great saphenous varicose veins with a 2-year follow-up.

Endovenous laser therapy (EVLT) for ablation of the great saphenous vein (GSV) is thought to minimize postoperative morbidity compared with high ligation and stripping (HL/S). Only a few randomized trials have reported early results. This prospective randomized trial compared EVLT (980 nm) and HL/S results at 1 and 2 years after the intervention. Patients with symptomatic varicose veins due to GSV insufficiency were randomized to HL/S (100 limbs) or EVLT (104 limbs). Four EVLT procedures failed primarily and were excluded. Phlebectomy and ligature of incompetent perforators were performed whenever indicated in both groups. Patients were re-examined clinically and by duplex ultrasound imaging preoperatively and at 12 days and at 1 and 2 years after treatment. Closure rate, complication rate, time to return to normal activity, the Aberdeen Varicose Vein Symptom Severity Score (AVVSS), the Varicose Venous Clinical Severity Score (VVCSS), and the Medical Outcome Study Short Form-36 scores were also recorded. There were no differences in patient demographics, CEAP class, Widmer class, or severity scores between the groups. Simultaneous interventions did not differ between the groups. Similar times for the return to normal activity and scores for postoperative pain were reported. No major complications after treatment were recorded. HL/S limbs had significantly more postoperative hematomas than EVLT limbs, and EVLT patients reported more bruising. Follow-up at 1 year was 100% for HL/S and 99% for EVLT. Two GSVs in the EVLT group reopened and three partially reopened. No open GSVs occurred in HL/S limbs. Ninety-eight percent of the limbs in both groups were free of symptoms. VCSS, AVVSS, and Short Form-36 scores did not reveal any group differences. At 2 years, no differences compared with 1-year results were observed, except that two more GSVs in the EVLT group were partially reopened. Abolition of GSV reflux and improvement in quality of life was similar after HL/S and EVLT. After EVLT, however, two GSVs were found completely reopened and five were partially reopened, which was significantly higher than after HL/S. A prolonged follow-up is ongoing.

Comparison of disease-specific quality of life tools in patients with chronic venous disease.

This work was presented as a poster in the American Venous Forum 25th Annual Meeting; 28 February 2013; Phoenix, Arizona, USA. Quality of life (QoL) is an important outcome measure in the treatment for chronic venous disease. The Aberdeen Varicose Vein Questionnaire (AVVQ) and the ChronIc Venous Insufficiency quality of life Questionnaire (CIVIQ-14) are two validated disease-specific QoL questionnaires in current use. The aim of this study is to evaluate the relationship between the AVVQ and the CIVIQ-14 to enable better comparison between studies and to compare these disease-specific QoL tools with generic QoL and clinician-driven tools. Adults attending our institution for management of their varicose veins completed the AVVQ, CIVIQ-14 and EuroQol-5D (EQ-5D). Clinical data, CEAP classification and the Venous Clinical Severity Score (VCSS) were collected. The relationship between the AVVQ and CIVIQ-14 scores was analysed using Spearman's correlation. The AVVQ and CIVIQ-14 scores were also analysed with a generic QoL tool (EQ-5D) and a clinician-driven tool, the VCSS. One hundred patients, mean age 57.5 (44 males; 56 females), participated in the study. The median AVVQ score was 21.9 (range 0-74) and the median CIVIQ-14 score was 30 (range 0-89). A strong correlation was demonstrated between the AVVQ and CIVIQ-14 scores (r = 0.8; p < 0.0001). Strong correlation was maintained for patients with C1-3 disease (r = 0.7; p < 0.0001) and C4-6 disease (r = 0.8; p < 0.0001). The VCSS correlated strongly with the AVVQ and CIVIQ-14 scores (r = 0.7; p < 0.0001 and r = 0.7; p < 0.0001, respectively). Both the AVVQ and CIVIQ-14 scores correlated well with the EQ-5D score (r = -0.5; p < 0.0001 and r = -0.7; p < 0.0001, respectively). This study demonstrates that there is good correlation between two widely used varicose vein specific QoL tools (AVVQ and CIVIQ-14) across the whole spectrum of disease severity. Strong correlation exists between these disease-specific QoL tools and generic and clinician-driven tools. Our findings confirm valid comparisons between studies using either disease-specific QoL tool.
