EHIT refers to the postprocedural propagation of thrombus after an endothermal ablation (eg, RFA or EVLA). The definition for EHIT is based on a specific relationship between the superficial vein that is being treated and the contiguous deep vein.

Compared with performing RFA alone, concurrent performance of stab phlebectomy and sclerotherapy with RFA on the left side was found to be associated with possible increased risk for EHIT...

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 ...

We sought to identify characteristics that may put patients at higher risk for development of EHIT after radiofrequency ablation (RFA) for the treatment of symptomatic superficial venous insufficiency.

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.

Treatment guidelines are tailored to the AVF EHIT class (ie, I, II, III, IV). Reference is made to the use of surveillance, antiplatelet therapy, and anticoagulants as deemed indicated, and the recommendations incorporate the use of the novel direct oral anticoagulants. Last, EHIT management as it relates to the great and small saphenous veins is

Objective: We aimed to determine the incidence of and associated risk factors for endovenous heat-induced thrombosis (EHIT) after endovenous radiofrequency ablation (RFA). Methods: We retrospectively reviewed the medical records of 82 patients with 97 great saphenous veins undergoing RFA from 2012 to 2014.

2013年8月1日 · We evaluated our experience with segmental radiofrequency ablation (RFA) of the small saphenous vein (SSV), a less common procedure than great saphenous vein ablation, and developed a classification system and algorithm for endovenous heat-induced thrombus (EHIT), based on modifications of our prior algorithm of EHIT following great saphenous ...

但RFA可增加静脉血栓的形成,并且延伸至深静脉导致深静脉血栓形成(deep vein thrombosis, DVT),这种情况称为静脉内热诱导血栓形成(endovenous heat-induced thrombosis,EHIT),根据血栓进入股静脉的wenku.baidu.com出程度,将EHIT分为4级[3]。

2023年12月4日 · 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 ...
