Objective: The objective of this presentation is to provide an in-depth analysis of our extensive experience and remarkable achievements in the application of CHIVA treatment for the treatment of various venous diseases in China. We aim to highlight the effectiveness and potential of CHIVA treatment as an innovative and minimally invasive approach.
Methods: We conducted a retrospective analysis of a well-defined cohort of 500 patients who underwent CHIVA treatment at our vein centers between 2012 and 2022. The patients were carefully selected based on specific criteria, including anatomical suitability and disease severity. CHIVA is a minimally invasive approach by recorrecting hemodynamic changes, preserving the venous drainage network in lower extremity. The surgical strategy was based on detailed preoperative Doppler ultrasound hemodynamic assessment and mapping.
Results: Our analysis demonstrated promising outcomes following CHIVA treatment. Of the 500 patients, 90% showed significant improvement in venous symptoms, such as pain, swelling, and ulceration. Doppler ultrasound imaging revealed a complete closure of escape points in 95% of cases. The overall success rate, defined as symptomatic relief and absence of venous reflux, reached 92%. Post-operative recovery was rapid, with patients resuming their daily activities within a few hours. Additionally, long-term follow-up assessments showed sustained improvement in venous disease management, with a low rate of recurrence (5%) and complication (3.6%) over a ten-year period.
Conclusions: Our extensive experience with CHIVA treatment in China demonstrates its effectiveness as a viable treatment option for venous diseases. The high success rates, significant symptom relief, and low complication rates observed in our patient cohort highlight the potential of CHIVA treatment in improving the quality of life for individuals suffering from venous insufficiency. Accurate ultrasound assessment and a deeper understanding of venous hemodynamics appear to be crucial for achieving satisfactory outcomes, CHIVA treatment enables precise blockage of escape points, preservation of the GSV trunk, and a quick return to normal work and daily activities.While challenges related to training and resource availability exist, our findings emphasize the need for further research, international collaboration, and continued advancements in CHIVA techniques to expand its application and benefit a larger patient population.
