Cerebral infarction due to acute embolism in the large artery during pregnancy is a rare but severe condition threatening both the mother's and child's life. Physicians lack diagnostic and therapeutic guidance to manage this particular situation due to the paucity of published cases. Furthermore, the pathogeny is poorly known, rendering preventive strategies difficult. We describe the case of a young woman presenting cryptogenic acute cerebral infarction during the first trimester of pregnancy who was successfully treated with combined reperfusion therapy. We reviewed the literature to collect data about pathogeny and management. A 28-year-old pregnant woman was diagnosed with acute cerebral infarction due to left middle cerebral artery occlusion at 9 weeks of gestation. Endovascular thrombectomy combined with intravenous thrombolysis allowed cerebral reperfusion leading to a decrease in the National Institute of Health Stroke Score from 13 to 1 at 24 hours. Comprehensive etiological investigation was negative. Anticoagulation therapy with low-molecular-weight heparin was administered as preventive treatment during the pregnancy and postpartum. Neither the mother nor the child experienced any complications: the baby was born by normal vaginal delivery and the outcome was good at 1 year. We identified 21 other cases of patients treated with reperfusion therapies, four of which consisted of endovascular thrombectomy, and only one a combined strategy. Pregnant women with acute cerebral infarction due to arterial occlusion can benefit from combined reperfusion therapy. More cases should be collected to assess treatment in these patients, to understand pathogeny, and propose the best preventive strategy.
