On January 4, 2025, the Guangdong–Hong Kong–Macao Greater Bay Area CHIVA Academic Salon on varicose vein treatment was held at the Shenzhen CHIVA Center of Dr. Smile Medical Group. Vascular surgeons from Hong Kong and mainland China gathered in Shenzhen to exchange ideas on the hemodynamic concept and its clinical application in the treatment of venous diseases.
The meeting was chaired by Dr. Qiang Zhang, founder of Dr. Smile Medical Group. In his opening remarks, Dr. Zhang noted that as hemodynamic concepts continue to gain attention in the management of chronic venous insufficiency, more physicians are beginning to focus on preserving venous function and reconstructing physiological venous drainage pathways. Academic exchanges across regions, he said, play an important role in deepening understanding and promoting clinical application of these concepts.
The salon featured the participation of a consultant vascular surgeon from Queen Elizabeth Hospital Hong Kong, as well as physicians from several cities in mainland China. Participants engaged in discussions on the diagnosis and evaluation of chronic venous insufficiency, hemodynamic analysis, and clinical experiences related to CHIVA (Conservative and Hemodynamic treatment of Venous Insufficiency).
During the event, Dr. Deng Jianping of the Shenzhen CHIVA Center conducted a live case demonstration. Through real-time ultrasound evaluation and procedural explanation, he illustrated the role of hemodynamic assessment in preoperative decision-making within the CHIVA approach. The demonstration prompted active discussion among participants on identifying reflux pathways, determining shunt points, and designing individualized treatment strategies.
CHIVA is a vein-preserving treatment strategy based on hemodynamic assessment. Unlike traditional approaches that focus on vein removal or ablation, CHIVA emphasizes analyzing venous reflux patterns and reconstructing physiological drainage pathways, thereby improving venous function while preserving the venous structure. In recent years, this concept has attracted growing interest in the international field of venous disease management.
As one of the most dynamic regions for medical collaboration, the Guangdong–Hong Kong–Macao Greater Bay Area provides an important platform for cross-regional academic exchange. The salon not only facilitated professional interaction between physicians from Hong Kong and mainland China, but also created opportunities to further promote hemodynamic concepts in the treatment of venous diseases.
Dr. Smile Medical Group stated that it will continue to support academic exchanges and training programs related to the CHIVA concept through case discussions, clinical demonstrations, and educational events, contributing to the ongoing development of venous disease management.
The academic salon concluded successfully after extensive discussions. Participants agreed that such clinically focused exchanges are valuable in advancing the understanding and application of hemodynamic principles in venous disease treatment.
