“…The results showed that EMA resulted in lower ecchymosis complications but higher skin burn and paralysis complications than EVLA, although the operation time and length of hospital stay had no significant difference. Yang et al reported that EMA had a shorter procedure time, lower incidence of induration and ecchymosis, and lower local recurrence below the knee compared with EVLA 14. From the current studies, the evidence on whether EMA is not inferior to EVLA is still insufficient.…”

“…A retrospective study from Mao et al reported the short-term (6 months) occlusion rate of EMA and EVLA, where EMA was a little higher than EVLA 13. Yang et al performed a cohort study comparing the efficiency of EMA with EVLA, and found that EMA displayed a similar occlusion rate and lower complications compared with EVLA 14. A limitation of this study is that it is not a randomised trial, which may cause some selective bias 14…”

IntroductionEndovenous microwave ablation (EMA) is a relatively novel thermal ablation treatment for great saphenous vein (GSV) varicosis, and its efficacy and safety are rarely reported. This study aims to explore whether EMA can be comparable to endovenous laser ablation (EVLA), which is a widely used thermal ablation treatment in clinical practice.Methods and analysisThis is a multicentre, randomised controlled non-inferiority trial to compare the efficacy and safety of EMA and EVLA in patients with GSV varicosis. We will recruit 180 patients in 6 centres and randomly assign them into treatment group (EMA group) and control group (EVLA group) in a 1:1 ratio. The patients will return to the hospitals at 7 days, 3 months, 6 months and 12 months, and will be called at 1 month after the treatment for follow-up visits. The primary outcome is the occlusion rate of GSV immediately, at 6 months, and at 12 months after the treatment. The secondary outcomes are Venous Clinical Severity Score (VCSS), Aberdeen Varicose Vein Questionnaire (AVVQ) Score, operation time and instrument performance evaluation.Ethics and disseminationThis protocol has been approved by the Clinical Trial Ethics Committee of Beijing Hospital (2020BJYYEC-126–02), Peking Union Medical College Hospital (KS2020393), Beijing Tsinghua Changgung Hospital (No.20279-2-02), Beijing Luhe Hospital.Capital Medical University (2020-LHYW-030–01), the First Hospital of Hebei Medical University (No.2020249), and the First Affiliated Hospital of Xi’an Jiaotong University (XJTU1AF2021LSY-12). The trial results will be published in peer-reviewed journals.Trial registration numberNCT04726124.

“…This leads to vein occlusion and abolishes the superficial reflux. EMA was shown to be efficacious with 97% vein occlusion rate, with no recurrence (Wang et al, 2020). Complications of Endovenous ablation included the following: deep vein thrombosis, pulmonary embolism, pain syndrome, abscess, seroma, hyperpigmentation, and burn of the skin (Mao and Zhang, 2019).…”

Background: Lower limbs varicose veins are common in the adult population, The CEAP classification is a conventional way of staging varicose vein disease.Traditional treatment is surgery, which involves disconnection of sapheno-femoral and/or sapheno-opopliteal junctions with or without stripping of the superficial axial vein. the endovenous ablation is now the most widely used procedure and approximately occlusion rate of 95%. the Endovenous ablation techniques is Endovenous Microwave Ablation (EMA) which works by generating radio-frequency energy. It generates radiofrequency energy with the MICROTAZE OT-110 M machine. Aim: The aim of this study is using endovenous microwave ablation as a new technique in treatment of lower limb varicose veins according to the results, advantages, disadvantages and complications. Subjects and Methods: This study was conducted on 30 patients with varicose veins of lower limbs. It was conducted in the department of vascular surgery, Al- Azhar University Hospitals – Cairo (Al-Hussein and and said-Galal Hospitals). After taking a written consent, patients were subjected to Clinical evaluation and Duplex Ultrasound. Results: over weighted and patients with 30-50 years were the most. A statistically significant improvement was observed in AVVQ at different follow-up intervals.

Purpose: To improve the current microwave ablation catheter from causing injury by the over-temperature of catheter during the therapy. A new microwave ablation catheter with water-cooling circulation system and temperature-monitoring system was designed. Its effectiveness was verified in an ex vivo study. Materials and Methods: According to the theory that the heat can be transferred by convection between different mediums to balance the temperature. Designing water-cooling circulation system and temperature-monitoring system based on the microwave ablation catheter. Comparing the temperature of the catheters with or without water-cooling circulation system and comparing the range of ablation tissues by testing on the pork to verify its effectiveness. Results: The temperature of the MWAC without water-cooling circulation system would increase as using times increased. It would be over 45℃ after using the instrument for 3 times continuously, and the range of ablation tissues extends with injury. The temperature of the microwave ablation catheter with water-cooling circulation system would not be over 45℃ after using it for 50 times continuously, and it would not cause injury. Conclusion: The new microwave ablation catheter with water-cooling circulation system and temperature-monitoring system can constantly monitor the temperature and lower the temperature while using the instrument to prevent the patients’ native issue and medical staffs from burning, it can control the ablation range more efficiently and safer.
