Patient, operative, and surgeon factors that influence the effect of superficial venous surgery on disease-specific quality of life.

Abstract

Superficial venous surgery for CEAP 2 disease leads to an improvement in disease-specific quality of life (QoL) in the short term. However, which factors influence the magnitude of this improvement, how surgery affects QoL in patients with CEAP 4 to 6 disease, and whether this improvement is durable are not known. The objective of this study was to identify patient, operative, and surgeon factors that might influence the change in disease-specific QoL in the 2 years after superficial venous surgery. This prospective study was comprised of 203 unselected, consecutive patients with CEAP 2 to 6 disease who underwent saphenous with or without subfascial endoscopic perforator surgery and who completed the Aberdeen Varicose Vein Symptoms Severity Score (AVVSSS) before surgery and at 4 weeks, 6 months, and 2 years after surgery. Univariate and multivariate analyses were performed. At baseline, recurrent and ulcer (CEAP 5 and 6) diseases were associated with a higher (worse) AVVSSS. Surgery was associated with a significant improvement in median (interquartile range [IQR]) AVVSSS: baseline, 17.8 (11.8 to 27.2); 4 weeks, 13.8 (7.9 to 21.3); 6 months, 9.6 (4.2 to 15.8); and 2 years, 8.1 (4.0 to 14.7). One hundred seventy-five patients (86%) at 6 months and 177 patients (87%) at 2 years reported an improvement in AVVSSS. Postoperative AVVSSS at both 6 months and 2 years was most significantly influenced by preoperative score (P <.0001). After adjustment for baseline AVVSSS, the following factors were identified in multivariate analysis as having a significant and independent positive (+) or negative (-) impact on AVVSSS: at 6 months, (-) recurrent disease (P =.009), (-) CEAP 4 disease (P =.026); and at 2 years, (+) long saphenous surgery (P =.02), (-) CEAP 5 disease (P =.030). In this unselected series, saphenous surgery with or without subfascial endoscopic perforator surgery led to an improvement in disease-specific QoL in 87% of patients out to 2 years. Although univariate analysis results suggested that many baseline factors might be associated with outcome, multivariate analysis results suggested that only surgery for recurrent disease and for CEAP 4/5 disease remained as significant negative, and only long saphenous surgery as significant positive, independent prognostic factors. These data provide evidence of the medium-term clinical effectiveness of venous surgery across the full spectrum of CEAP clinical grades, show the importance of multivariate analysis, and reemphasize the importance of minimization of recurrence.
