A prospective observational cohort study of concomitant versus sequential phlebectomy for tributary varicosities following axial mechanochemical ablation

IntroductionEndovenous mechanochemical ablation (MOCA) is an increasingly popular non-thermal non-tumescent technique used to treat axial reflux in patients with superficial venous incompetence. However, the optimal management of varicose tributaries following this technique is unknown and may impact on patient outcomes. This study compares MOCA with concomitant phlebectomy (MOCAP) versus ablation with sequential phlebectomy if required (MOCAS).MethodsPatients with symptomatic Comprehensive Classification System for Chronic Venous Disorders (CEAP C2–C6) unilateral axial reflux were studied. Patient choice determined whether concomitant treatment of varicosities was carried out. The primary outcome was the Aberdeen Varicose Veins Questionnaire (AVVQ) at one year. Secondary outcomes included: Venous Clinical Severity Scores (VCSS), EuroQol 5-Domain quality of life scores, complications, procedure duration, procedural and post-operative pain scores and need for secondary procedures. Outcomes were assessed at...
