Abstract
Objective/Background: The objective was to identify predictors to develop and validate a prognostic model of recanalization of the great saphenous vein (GSV) in patients treated with endovenous radiofrequency ablation (RFA).Methods: This prospective study was carried to compare postoperative duplex results and risk factors associated with recanalization of the GSV after treatment with radiofrequency ablation at 1 year follow up. Candidate predictors were selected based on the available data. Patient characteristics (e.g., age, clinical class, and BMI, gender), patient risk factors ( smoking , hypertension , diabetes), DUS features (diameter of the GSV and presence of SFJ reflux) were considered as important predictors of recanalization.The primary outcome measure was recanalization of the GSV after follow up of at least 1 year. Recanalization was defined as an open section of the treated vein >5 cm in length. Secondary outcome was changed QOL at 1 year follow up compared with baseline QOL.Results: At 1 year, 10 GSVs were recanalized (10%). Recanalization increased with the increase in BMI, smoking and increased vein diameter. Hypertension, diabetes Mellitus , age and gender had no impact on recanalization. Conclusion: There are several important prognostic factors for GSV recanalization and change of HRQoL after EVTA.
