ABSTRACT

The coronavirus disease 2019 (COVID-19) pandemic has placed an immense burden on healthcare systems worldwide. There is intensive research targeted at better understanding of the virus pathogenicity, development of effective treatment strategies and vaccines against COVID-19. It is increasingly being recognised that the pathogenicity of COVID-19 extends beyond the respiratory system. In severe cases, there can be widespread activation of the immune system, vascular injury and a resultant pro-thrombotic state. Severe COVID-19 is widely regarded as a risk factor for venous thromboembolism. Interim European and American guidelines have been created to guide anticoagulation strategies in COVID-19 patients. However, it is unclear if these guidelines can be extrapolated directly to Asians, in whom there are differences in the baseline risk of thrombosis and bleeding. Our review article aimed to summarise the current understanding of arteriovenous thromboembolic complications in COVID-19 and discuss management strategies for prevention and treatment of thrombotic events in Asian COVID-19 patients.

ABSTRACT

OBJECTIVE: Identify clinical and radiographic features of venous infarct as a presenting feature of COVID-19 in the young. BACKGROUND: SARS-CoV-2 infection causes hypercoagulability and inflammation leading to venous thrombotic events (VTE). Although elderly patients with comorbidities are at higher risk, COVID-19 may also cause VTE in a broader patient population without these risks. Neurologic complications and manifestations of COVID-19, including neuropathies, seizures, strokes and encephalopathy usually occur in severe established cases of COVID-19 infection who primarily present with respiratory distress. CASE DESCRIPTION: Case report of a 29-year-old woman, with no significant past medical history or comorbidities, presenting with new onset seizures. Further questioning revealed a one-week history of headaches, low-grade fever, mild cough and shortness of breath, diagnosed as COVID-19. Imaging revealed a left temporoparietal hemorrhagic venous infarction with left transverse and sigmoid sinus thrombosis treated with full dose anticoagulation and antiepileptics. CONCLUSION: Although elderly patients with comorbidities are considered highest risk for COVID-19 neurologic complications, usually when systemic symptoms are severe, this case report emphasizes that young individuals are at risk for VTE with neurologic complications even when systemic symptoms are mild, likely induced by COVID-19 associated hypercoagulable state.
