abstract	Those who are infected with Severe Acute Respiratory Syndrome‐related CoronaVirus‐2 are theoretically at increased risk of venous thromboembolism during self‐isolation if they have reduced mobility or are dehydrated. Should patients develop coronavirus disease (COVID‐19) pneumonia requiring hospital admission for treatment of hypoxia, the risk for thromboembolic complications increases greatly. These thromboembolic events are the result of at least two distinct mechanisms – microvascular thrombosis in the pulmonary system (immunothrombosis) and hospital‐associated venous thromboembolism. Since pregnancy is a prothrombotic state, there is concern regarding the potentially increased risk of thrombotic complications among pregnant women with COVID‐19. To date, however, pregnant women do not appear to have a substantially increased risk of thrombotic complications related to COVID‐19. Nevertheless, several organizations have vigilantly issued pregnancy‐specific guidelines for thromboprophylaxis in COVID‐19. Discrepancies between these guidelines reflect the altruistic wish to protect patients and lack of high‐quality evidence available to inform clinical practice. Low molecular weight heparin (LMWH) is the drug of choice for thromboprophylaxis in pregnant women with COVID‐19. However, its utility in non‐pregnant patients is only established against venous thromboembolism, as LMWH may have little or no effect on immunothrombosis. Decisions about initiation and duration of prophylactic anticoagulation in the context of pregnancy and COVID‐19 must take into consideration disease severity, outpatient vs inpatient status, temporal relation between disease occurrence and timing of childbirth, and the underlying prothrombotic risk conferred by additional comorbidities. There is currently no evidence to recommend the use of intermediate or therapeutic doses of LMWH in thromboprophylaxis, which may increase bleeding risk without reducing thrombotic risk in pregnant patients with COVID‐19. Likewise, there is no evidence to comment on the role of low‐dose aspirin in thromboprophylaxis or of anti‐cytokine and antiviral agents in preventing immunothrombosis. These unanswered questions are being studied within the context of clinical trials.
