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).

2021年1月8日 · 4级：股总／腘静脉闭塞性深静脉血栓。 图1. SFJ EHIT分级. 治疗方式. 根据SPJ EHIT分级，选择相应的治疗方式（图2）。 对于A类和B类EHIT不需要治疗，对于C类采取外科手术治疗，D类接受LMWH和华法林联合治疗。 图2. 不同分级治疗选择. 在EHIT最初的术后记录中，血栓进一步蔓延的可能性很低。 大多数患者，血栓通常较稳定，并在10～14天内消退或完全溶解。 在某种程度上，EHIT能与SVT相比，而且治疗方式仍存在争议。 治疗时，可以借助超声辅助 …

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.

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.

2020年9月29日 · We suggest treatment with therapeutic anticoagulation for EHIT III, weekly surveillance, and cessation of treatment after thrombus retraction or resolution to the saphenofemoral (GSV) or saphenopopliteal (SSV) junction.
