Dr. Qiang Zhang is a vascular surgeon with more than three decades of clinical experience in the treatment of venous disease. His work focuses on the hemodynamic understanding of varicose veins and the development of vein-preserving treatment strategies, including the CHIVA method. Over the course of his career, Dr. Zhang and his team have treated more than 100,000 patients with varicose veins, contributing extensive clinical experience to the field of venous medicine. Dr. Zhang is the founder of Dr. Smile Medical Group, a network of vein centers dedicated to the treatment of chronic venous disease. Through clinical practice and physician education, the organization promotes approaches that aim to preserve the physiological function of the venous system while addressing venous insufficiency.
