Stroke and pregnancy.

Strategies for stroke prevention should take into account the competing risks to mother and fetus. Treatment of acute stroke in pregnant women is still controversial, but not strictly contraindicated. Several case reports have documented successful reperfusion, in addition to satisfactory maternal and fetal outcomes. Aspirin and warfarin are safe in the second and third trimesters. There are no trials of anticoagulation or antiplatelet therapies of stroke prevention in pregnancy.
