Abstract
La Enfermedad Tromboembólica Venosa es una patología caracterizada por la formación inapropiada de coágulos en el sistema venoso. Si bien habitualmente afecta a las arterias pulmonares y los miembros inferiores, puede darse también en sitios poco frecuentes, como el territorio esplácnico o el sistema venoso cerebral. Se conoce en estos casos como Trombosis en Sitios Inusuales (TUS), y su incidencia exacta no es conocida. La infección por COVID-19 también se ha asociado con la enfermedad tromboembólica venosa, aunque su incidencia y el riesgo de recurrencia reales no están del todo claros. El diagnóstico de la enfermedad tromboembólica venosa se basa principalmente en la sospecha clínica. En algunos casos, un test de dímero D puede ayudar a identificar pacientes con alta probabilidad de enfermedad tromboembólica venosa, habitualmente en conjunto con una escala clínica pre-test. Sin embargo, el uso del dímero-D en TUS no está bien definido, y no se han establecido puntos de corte para cada subtipo de TUS. Su utilidad también ha sido cuestionada en la enfermedad tromboembólica venosa asociada a COVID-19, dada la coagulopatía que puede aparecer en estos pacientes...
Venous thromboembolism (VTE) is a condition characterized by the inappropriate formation of blood clots within the venous system. While it commonly affects the pulmonary arteries and the lower limbs, it can also occur in unusual sites such as the splanchnic veins or the cerebral venous system, known as thrombosis in unusual sites (TUS). The exact incidence of TUS is not well defined.COVID-19 infection has also been associated with VTE, although the true incidence and recurrence risk remain unclear. Diagnosis of VTE primarily relies on clinical suspicion. In some cases, a D-dimer test may be performed to assist in identifying patients with a higher likelihood of VTE, typically in conjunction with a clinical pretest score. Nevertheless, the use of D-dimer levels in TUS is not widespread, and specific cut-off levels have not been established for each type of TUS. Its usefulness has also been questioned in COVID-19 patients due to the coagulopathy that can develop in severe cases...
