COVID-19, thrombosis and pregnancy

Increased thromboembolic events have been seen in patients hospitalised with COVID-19 pneumonia, especially those with acute respiratory distress syndrome requiring intensive care support. The coronavirus pandemic has had varied effects on pregnant women globally. Concerns about the potential for thromboembolic events in the prothrombotic period of pregnancy and puerperium when combined with COVID-19 infection, and the impact this may have on maternal and infant morbidity and mortality has led to the development of expert-led guidance providing increased use of thromboprophylaxis in this group. We discuss the impact of SARS-CoV-2 on national and international guidance to prevent thromboembolic events in pregnant women.
