Abstract
Introduction: Chronic venous disease management has significantly advanced with minimally invasive techniques like endovenous thermal ablation. High-intensity focused ultrasound (HIFU) is a non-invasive alternative thermal ablation method enabling targeted vein closure without percutaneous access. This study evaluates the efficacy of HIFU treatment, combined with the CHIVA strategy, in occluding leak points in patients with superficial venous reflux.
Methods: This retrospective study included patients treated for chronic venous disease using the SONOVEIN® device from March 2020 to February 2024. Inclusion criteria were symptomatic patients (CEAP ≥ C2) with ultrasound-confirmed truncal reflux. Patients under 18 years, with <12 months life expectancy or isolated venous flow obstruction were excluded. Treatments followed CHIVA principles, targeting leak points and proximal vein segments for occlusion. Primary endpoints were leak point occlusion rates and procedural safety. In this study, primary efficacy was defined as vein closure with one treatment, while secondary efficacy was defined as the need for more.
Results: A total of 204 limbs in 183 patients (131 females, 52 males; mean age 55.2 years) underwent HIFU treatment. Primary leak point occlusion rate at 1 week, 1, 6, 12 and 24 months were 85.1 %, 91.8%, 93.7%, 94.3% and 95.5% respectively. Secondary closure rates at 1 week, 1, 6, 12 and 24 months were 89.6 %, 95.4%, 95.0%, 95.4% and 95.7% respectively. Overall primary and secondary cumulative closure rates at 24 months were 88.1% (95% confidence interval (CI) 77.7-98.4%), and 92.1% (95% CI 83.3-100%) respectively. No major complications were observed.
Conclusion: High-intensity focused ultrasound achieves high leak point occlusion rates when applied under CHIVA principles, supporting its role as an effective and safe non-invasive alternative for chronic venous disease treatment. The technique minimizes risks associated with thermal ablation, such as skin burns and nerve damage while addressing limitations of conventional methods. These results highlight high-intensity focused ultrasound potential as a disruptive technology in venous disease management. Further studies should assess its long-term efficacy and safety.
期刊介绍:
Journal of Vascular Surgery: Venous and Lymphatic Disorders is one of a series of specialist journals launched by the Journal of Vascular Surgery. It aims to be the premier international Journal of medical, endovascular and surgical management of venous and lymphatic disorders. It publishes high quality clinical, research, case reports, techniques, and practice manuscripts related to all aspects of venous and lymphatic disorders, including malformations and wound care, with an emphasis on the practicing clinician. The journal seeks to provide novel and timely information to vascular surgeons, interventionalists, phlebologists, wound care specialists, and allied health professionals who treat patients presenting with vascular and lymphatic disorders. As the official publication of The Society for Vascular Surgery and the American Venous Forum, the Journal will publish, after peer review, selected papers presented at the annual meeting of these organizations and affiliated vascular societies, as well as original articles from members and non-members.
