Patient characteristics and physician-determined variables affecting saphenofemoral reflux recurrence after ligation and stripping of the great saphenous vein

To identify patient and physician-controlled treatment variables that might predict the persistence or redevelopment of saphenofemoral junction (SFJ) reflux. Thirteen European centers, with substantial lower extremity venous disease practices, examined their experience with SFJ ligation and GSV stripping for primary varicose veins in patients followed for ≥2 years, entering their data into a protocol-driven matrix that stipulated duplex Doppler imaging as an essential component of follow-up examinations and required a complete review of all peri-operative examinations, as well as all operative procedure and anesthesia notes. Matrix entries were centrally audited for consistency and credibility, and queried for correction or clarification before being accepted into the study database. Presence or absence of Doppler-detectable SFJ reflux was the dependent variable and principal outcome measure. Among 1,638 limbs, 315 (19.2%) had SFJ reflux. After adjustment for follow-up length and imputing for missing values, multivariable analysis identified seven significant predictors. Ultrasonic groin mapping (odds ratio [OR], 0.28; 95% confidence interval [CI], 0.20 to 0.40) and 29 kg/m2 (OR, 1.65; 95% CI, 1.12 to 2.43),
