Abstract
Maternal ischemic stroke and cerebral venous sinus thrombosis (CVST) are dreaded complications of pregnancy and major contributors to maternal disability and mortality. This chapter summarizes the incidence and risk factors for maternal arterial ischemic stroke (AIS) and CVST and discusses the pathophysiology of maternal AIS and CVST. The diagnosis, treatment, and secondary preventive strategies for maternal stroke are also reviewed. Special populations at high risk of maternal stroke, including women with moyamoya disease, sickle cell disease, HIV, thrombophilia, and genetic cerebrovascular disorders, are highlighted.

Abstract
Patent foramen ovale (PFO)-related stroke is increasingly recognized as an important etiology of ischemic embolic stroke-accounting for up to 50% of strokes previously considered 'cryptogenic' or with an unknown mechanism. As a 'back door to the brain,' PFO can allow venous clots to enter arterial circulation via interatrial right-to-left shunting, potentially resulting in ischemic stroke. We observe that clinically, PFO-related stroke affects women of childbearing age, and that pregnancy-owing to major changes in hemocoagulative, hormonal, and cardiovascular parameters-can enhance stroke risks. However, no systematic study has been performed and little is known regarding complications, pregnancy outcomes and treatment for PFO-related stroke during pregnancy. To identify and characterize the complications and clinical outcomes related to PFOs during pregnancy, we performed a literature review and analysis from all reported cases of pregnancy with PFO-related complications in the medical literature from 1970 to 2015. We find that during pregnancy and post-partum, PFO is associated with complications affecting multiple organs, including the brain, heart and lung. The three principal complications reported are stroke, pulmonary emboli and myocardial infarction. In contrast to other pregnancy-related stroke etiologies, which peak during later pregnancy and postpartum, PFO-related stroke peaks during early pregnancy (first and second trimester-60%), and most patients had good neurological outcome (77%). In patients with PFO with recurrent stroke during pregnancy, additional key factors include high-risk PFO morphology (atrial septal aneurysm), larger right-to-left shunt, multiple gestation and concurrent hypercoagulability. Compared to strokes of other etiologies during pregnancy, most PFO stroke patients experienced uneventful delivery (93%) of healthy babies with a good clinical outcome. We conclude with recommended clinical treatment strategies for pregnant patients with PFO suggested by the data from these cases, and the clinical experience of our Cardio-Neurology Clinic.

Abstract
BACKGROUND Idiopathic facial (Bell's) palsy occurring during pregnancy or post partum is a rare disease. Reports regarding incidence, prognosis and associated risk factors are still inconsistent. MATERIAL AND METHODS We performed a retrospective analysis of patients presenting with idiopathic facial palsy who had been treated in cooperation between obstetric and otorhinolaryngological departments (tertiary referral centers). The time of onset of paralysis, grading according to House and Brackman, treatment modalities and results were analyzed for the years 1999-2010. RESULTS The incidence of Bell's palsy in pregnancy was 56 in 100,000 live births. Preeclampsia was reported in one case only. Therapy included prednisolone, methylprednisolone and/or pentoxifylline (up to 2005). All results were favorable (House-Brackman 1-2). CONCLUSION The incidence of Bell's palsy in pregnancy within our cohort is not increased with regard to the international reports. Early treatment with corticosteroids in consultation with the treating obstetrician is indicated in both pregnant and post-partum patients to achieve optimal results.
