    Sammanfattning : Introduction: Thromboembolic complications affect a large proportion of patients with critical COVID-19, and it may be associated with an increased risk of death. It has been hypothesized that both the virus of SARS-CoV-2 itself and the inflammation caused by the infection puts patients in a pro-coagulative state. LÄS MER
