- Abstract
- We report a young woman who survived multiple cerebral infarctions related to an amniotic fluid embolism (AFE) during labor. To our knowledge, an embolic stroke due to the coexistence of an AFE and patent foramen ovale (PFO) has not been reported. We describe the patient's clinical and radiological features and discuss the stroke mechanism in relation to our AFE hypothesis. A 32-year-old woman presented to the emergency room after experiencing convulsions during labor (blood pressure, 64/28 mmHg; oxygen saturation, 67%). She was in a stupor, and her response to painful stimuli on the right side was weaker than on the left side. Acute stroke was considered as a possible cause. Additionally, an APE was suspected due to cardiopulmonary arrest during labor. Brain MRI revealed multiple territory embolic infarctions. The transcranial Doppler with bubble study demonstrated a right-to-left shunt during the Valsalva maneuver. A transesophageal echocardiogram revealed a PFO with a right-to-left shunt. The elevated intrathoracic pressure during labor may have caused blood to flow backward through the heart, shunting blood from the right side to the left through the PFO. In cases such as this, an amniotic fluid embolus may travel directly from the venous to the arterial circulation via the PFO, leading to multiple cerebral infarctions. (C) 2014 Elsevier Ltd.
