Abstract
Objective: To evaluate the efficacy and outcomes of patients who underwent microwave ablation (MWA) to treat the lower limb's truncal varicose veins (VVs).
Patients and Methods: The study included all adult patients with truncal VVs of clinical, aetiological, anatomical, and pathological (CEAP) classification (C 2-6) who underwent MWA of the great saphenous vein (GSV) and /or short saphenous vein (SSV) with vein diameter 5.5-15mm and reflux time > 0.5 sec.
Results: The study included 20 patients with a mean age of 33 ± 10.4 years. The majority of patients (70%) were females. A history of prolonged standing was the most common risk factor (70%). The mean diameter of GSV was 9.2. ± 0.08 mm. According to the CEAP classification, C2 was the most common presentation. The mean time of the procedure was 56.9 ± 3.3 minutes, while the mean time to ambulation was 3.9 ± 0.3 hours. Technical success was achieved in all patients. There was a significant improvement in VAS score from 3.4 preoperatively to 2.4 at 24 hours postoperatively, P = <0.001. Complete occlusion was noticed in all patients undergoing a duplex ultrasound examination one month postoperatively. Over the 1-year follow-up period, there was a highly significant reduction in the Aberdeen Varicose Vein Questionnaire (AVVQ) score (7.6 vs 33.9, P =< 0.001). Patients with venous ulcers showed complete ulcer healing within 3 months. The occlusion rates at 3,6 and 12 months were 95.0%, 90.0%, and 85.0%, respectively.
Conclusion: MWA is a safe and effective minimally invasive treatment for truncal VVs. MWA offers advantages like short operation times, minimal postoperative pain sensation, and fast recovery.
