Current status of endothermal heat induced thrombosis

There remain many questions regarding the pathophysiology and risk factors for endothermal heat induced thrombosis formation. Moreover, there are a paucity of data on the timing of its occurrence, and there has been no consensus regarding for its treatment. The purpose of this review was to summarize the current knowledge on the pathophysiology, risk factors and treatment strategies for endothermal heat induced thrombosis. The PubMed database was searched from 2001 to present for endothermal heat induced thrombosis, EHIT, deep vein thrombosis, chronic venous insufficiency, varicose veins, endovenous laser and radiofrequency ablation (treatment). All relevant articles identified by the authors mentioning endothermal heat induced thrombosis were included in this review. A multitude of risk factors, several pathophysiological hypotheses and different treatment strategies are described in the literature. Endothermal heat induced thrombosis is marginally understood. There remains a theoretical risk for significant venous thromboembolic complications. With the new uniform classification of EHIT (American Venous Forum), healthcare providers should continue to investigate the nature of this event.
