Ictus isquémico por oclusión de la arteria basilar en una paciente puérpera con infección por SARS-CoV-2

INTRODUCTION. Infection by coronavirus type 2, which is the cause of severe acute respiratory syndrome (SARS-CoV-2), gives rise to thromboembolic complications, including acute cerebrovascular disease. Due to the hypercoagulable state that accompanies pregnancy, the thrombotic risk in these patients may be particularly significant. CASE REPORT. We report the case of a 41-year-old woman, 34+1 weeks pregnant, diagnosed with bilateral interstitial pneumonia, caused by coronavirus disease 2019 (COVID-19). The patient presented with severe respiratory failure, and so the decision was made to perform an emergency caesarean section and she was transferred to the intensive care unit. During her stay in hospital, the patient suffered a sudden episode of decreased level of consciousness, and magnetic resonance angiography revealed thrombosis in the left vertebral artery and in the basilar artery, with the presence of acute ischaemic infarction in both cerebellar hemispheres and bilateral involvement of the brainstem. CONCLUSION. Severe SARS-CoV-2 disease results in a prothrombotic state that correlates with the prognosis of the disease. The last trimester of pregnancy and the puerperium are known prothrombotic risk factors. Recommendations for anticoagulation management in pregnant patients with COVID-19 are based on limited evidence. This is the first case to be published in Spain involving cerebral arterial thrombosis in a pregnant patient with SARS-CoV-2 infection.
