Rationale

The integration of the Kavallieros (2026) meta-analysis provides the most current evidence regarding recurrence patterns (REVAS) following superficial venous interventions. This addition enhances the 'Long-term outcomes' section by moving beyond simple recurrence rates to acknowledge the qualitative patterns of recurrence identified in recent high-level evidence. Abbreviations for EVLA and RFA were expanded to meet the required formatting standards.

**Long-term outcomes:**

Endothermal ablation techniquestechniques, (EVLAincluding endovenous laser ablation (EVLA) and RFA)radiofrequency ablation (RFA), demonstrate durable anatomic closure rates of 85–95% at 3–5 years. Success rates depend on device selection, energy delivery parameters, operator experience, and vein diameter. Contemporary meta-analyses and randomized trials confirm sustained clinical improvement with low recurrence ratesrates, although specific patterns of recurrent varicose veins after surgery (REVAS) vary depending on the primary intervention modality [@vandenbos2009, @brittenden2014].@brittenden2014, @kavallieros2026].
