It is a four-tiered classification: I, junction; II, <50% lumen; III, >50% lumen; IV, occlusive deep venous thrombosis. [BEST PRACTICE] Some possible but inconsistent predictors or risk factors for EHIT include large GSV diameter, previous history …

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 ...

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.

It is a four-tiered classication: I, junction; II, <50% lumen; III, 50% lumen; IV, occlusive deep venous thrombosis. Guideline 2.1: Risk factors for EHIT. Some possible but inconsistent predictors or risk factors for EHIT include large GSV diameter, previous history of venous throm-boembolic disease, and male sex.

2021年1月1日 · Recommendations codify the use of duplex ultrasound for the diagnosis of EHIT. Risk factor assessments and methods of prevention including mechanical prophylaxis, chemical prophylaxis, and ablation distance are discussed. Treatment guidelines are tailored to the AVF EHIT class (ie, I, II, III, IV).

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.

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.

2020年9月28日 · 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...

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.

EHIT after EVLA occurs frequently and mainly consists of low-risk level 3, 4, and 5 deep vein thrombosis. The risk of pulmonary embolism is low and the EHIT typically resolves after 1 week. It can be treated with a short course of antiplatelet or …
