Comparative study of using Microwave Catheter by Infragenicular or Supramalleolar access in the Treatment of Primary Lower Limb Varicose Veins

Background: To enhance results for patients with Autism Spectrum Disorder (ASD) and concurrent skin disorders. Aim of the work: The objective is to analyze and assess the technical aspects and outcomes of utilizing a microwave catheter for treating primary lower limb varicose veins, specifically focusing on the venous access. The study aims to compare the effectiveness of infragenicular and supramalleolar access methods. Patients and Methods: From March 2023 to March 2024, the Department of Vascular Surgery at Al-Azhar University Hospitals treated 30 patients with lower limb primary varicose veins using endovenous microwave catheter ablation. Results: The success rate of endovenous microwave catheter ablation in this study was 15 patients (100%) in both infragenicular and supramalleolar groups on the first postoperative day. However, it declined to 14 patients (93.3%) in both study groups in the second week and first month postoperatively. The incidence of ecchymosis was 16.67% in total, which was less in the intravesicular group than in the supra-malleolar group. The incidence of skin burns was 10% in total, which was more in the intravesicular group than the supra malleolar group. At the same time, the incidence of paresthesia was 10% in total, which was more in the supramalleolar group than the infragenicular group. Conclusion: There were no appreciable variations between the two microwave ablation entry points. Our findings demonstrate the effectiveness and safety of both accesses.
