Introduction:

Severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) is a virus that can cause respiratory infections and pose a risk to patients’ lives. While it primarily affects the airways, it can also lead to extrapulmonary clinical manifestations, such as hypercoagulable states, resulting in conditions like cerebrovascular disease, acute myocardial infarction, and, in rare cases, Budd-Chiari syndrome.

Clinical case:

This case involves a patient who was admitted to the emergency room with dyspnea on moderate exertion, progressive functional class deterioration, lower extremity edema, cough, fever, and weakness. The patient had a history of coronavirus disease 2019 (COVID-19) infection one month prior. Abdominal CT scan revealed subacute Budd-Chiari syndrome involving the middle sub-hepatic vein, along with right ventricle thrombosis, and a positive test for SARS-CoV-2.

Conclusions:

Budd-Chiari syndrome has multiple causes, primarily associated with hypercoagulable states or the presence of neoplasms that disrupt liver function or obstruct hepatic venous drainage. However, the understanding of the relationship between COVID-19 hypercoagulability and Budd-Chiari syndrome is still limited. Further research is needed to explore the heterogeneity of its pathogenesis in the context of the SARS-CoV-2 pandemic.
