2014年1月27日 · Deep venous thrombosis (DVT) is the formation of a thrombus within the deep venous system and is a recognized complication associated with less than 1% of endovenous ablation procedures. Endovenous heat induced thrombus (EHIT) is and expected result of endovenous ablation of an incompetent superficial vein.

Patients who develop class Ib EHIT (central to the epigastric vein, up to and including the deep vein junction) may be considered for individualized treatment and surveillance. Several authors recommend antiplatelet therapy for such cases of EHIT, noting no cases of thrombus propagation after treatment. 65 , 66 Others support simply observation ...

Propagation of a thrombus from a superficial vein into a deeper vein post endovenous thermal ablation is called endothermal heat-induced thrombosis (EHIT). It is generally considered clinically insignificant if the thrombus does not propagate to the deep venous system.

The American Venous Forum (AVF) and the Society for Vascular Surgery set forth these guidelines for the management of endothermal heat-induced thrombosis (EHIT). The guidelines serve to compile the body of literature on EHIT and to put forth evidence-based recommendations.

Endothermal heat-induced thrombosis (EHIT) refers to the propagation of thrombus into the deep vein contiguous with a superficial vein that has been ablated with endothermal methods 1 including radiofrequency (RFA) and endovenous laser ablation (EVLA). Unlike deep venous thrombosis (DVT), EHIT is a unique entity that has a distinctive ...

2021年1月1日 · Deep vein thrombosis (DVT) after venous thermoablation techniques: rates of endovenous heat-induced thrombosis (EHIT) and classical DVT after radiofrequency and endovenous laser ablation in a single centre

mal-heat induced thrombosis (EHIT), defining it as the propagation of thrombus into the deep vein contiguous with the ablated superficial vein.23 This definition has been widely adopted to describe this clinical entity. From a diagnostic and clinical standpoint, EHIT is an en-tity separate from classic DVT. EHIT, for the most part, has

2019年1月1日 · Endothermal ablation techniques used to treat superficial venous reflux, such as endovenous laser ablation (EVLA) and radiofrequency ablation (RFA), use heat to induce endothelial injury. This results in a combination of thrombosis, fibrosis, subsequent vein contracture, and eventual occlusion of the treated vein.
