Endothermal Heat Induced Thrombosis

Abstract

AbstractEndothermal heat induced thrombosis (EHIT) is a post-procedural entity following endothermal superficial venous ablation that refers to the propagation of thrombus into the adjacent deep vein lumen. It is identified most commonly during the post-procedural surveillance venous duplex ultrasound. EHIT is recognized as a unique post-procedural entity, distinct in clinical behavior from a deep vein thrombosis. The definition, classification systems, pathophysiology, risk factors, treatment, and prevention are all discussed. The understanding of EHIT has advanced considerably, but additional data are required to understand its impact on quality of life and the cost-effectiveness of surveillance.
