Objective the aim of this study was to assess the results of mechanochemical endovenous ablation either in the primary or recurrent saphenous vein insufficiency, including only patients with veno-venous shunt type III. Methods retrospective analysis of a prospective study of patients with symptomatic chronic venous insufficiency who underwent ClariVein® technique. A total of 134 saphenous veins were included between August 2017 and August 2018. Follow-up was performed by Duplex ultrasound at 1, 6 and 12 months. Primary endpoints were technical and anatomical success. Secondary endpoints were the need for further treatment of varicose collateral veins by sclerotherapy, outcomes regarding recurrent insufficiency and clinical success. Results A total of 111 great saphenous veins and 23 small saphenous veins were treated with a technical success of 95.6%. The overall anatomical success rates at 1, 6 and 12 month were 96.2%, 88.8% and 84.4%, respectively, without differences between primary and recurrent insufficiency. Deferred sclerotherapy over varicose collaterals was carried out in 28% of the patients with anatomical success. Clinical improvement was achieved in 87.3%. Conclusions MOCA technique has proven to be an effective technique, although additional treatment over varicose collaterals could be necessary in up to one-third. Atrophy of the saphenous vein and the lack of persistent varicose collateral veins during follow-up seem to be indicators of successful therapy.
provided excellent results in occlusion rates, associated with very low rate of adverse events. The reason of our study is to demonstrate the safety and efficacy of VCS outside of a conventional operating room. Methods: A prospective, multi-investigator, randomized study was conducted in two different centers. Between May 2016 and February 2018, a total of 103 saphenous veins were treated in the 83 patients recruited. The patients were divided into two groups (group A, patients who underwent surgery in a conventional surgical room and group B patients operated on in our minor ambulatory surgical room), with the objective of identifying differences in stress level and satisfaction with the procedure performed. In both groups of patients two specialists follow the same surgical protocol, without the application of sedation, regional or general anesthesia. After the procedure, the patient rated pain during the procedure in the limb using a 10-point numerical pain rating scale (NRS), likewise he was asked to score from 0 to 3 previous stress sensation previous and after surgery. All patients revisited the clinic for evaluation 10 days, 1 month, and 3 months post procedural. Results: All treated veins (89 GSV, 9 SSV and 5 ASV) had complete closure by duplex ultrasound during the followup period. Of all the patients who underwent surgery, only 14 (17%) required coadjutant treatment with aetoxisclerol of their residual collateral varices. No phlebotomies were performed. Adverse events (phlebitis like), in the treatment area were occur in 22% of saphenous veins treated. In the Pain Rating Scale (NRS) questionnaire, group B had less pain perception 2.3 AE 1, 2 (0-8). In relation to the sensation of stress previous and after surgery, the 82% of patiens of group B had an initial score between 0-1 in comparison with 44% of group A, this score equalizes in the postoperative with 90% in both groups. Conclusion: This study shows that the use of CVCS is safe and effective in the treatment of CVI outside of a convencional operating room, maintaining the same high occlusion and low adverse events rates with the advantage of reducing the sensation of stress of the patient prior to the procedure. However, there are still many undefined variables and more studies should be done.
