EHIT: any thrombus detected by ultrasound within 4 weeks of endovenous thermal ablation originating from the treated vein and protruding into a deep vein. Non-EHIT DVT: a DVT occurring in a venous segment not contiguous with the thermally ablated vein.

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).

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).

2020年9月29日 · 2 – Weak Benefits and risks are more closely matched and are more dependent on specific clinical scenarios

The venous clinical severity score for baseline, 1st, 6th, and 12th months, great saphenous vein occlusion at the 1st, 6th, and 12th months, and ulcer rates for the 1st, 2nd, 3rd, 4th, and 5th ...

The 4Ts Score is a clinical scoring system to differentiate patients with HIT from those with other causes of thrombocytopenia.

2013年4月1日 · Endovenous radiofrequency ablation has become an accepted mode of treatment for superficial venous reflux. In this study, we evaluated the incidence of endovenous heat-induced thrombosis (EHIT), its progression, and risk factors that may contribute to its formation.

The Caprini score system, which uses several VTE risk factors, has been studied in patients undergoing thermal vein ablation to assess its EHIT development predictability. 61 In a series of 519 vein ablations, this system was found to aid in identifying patients who are at higher risk for development of EHIT. 55 A mean Caprini score of 6.9 ± 2 ...
