AB  - Stroke  is  relatively  uncommon  in  women  of  childbearing  age.  The  occurrence  of  stroke  during  pregnancy  has  the  potential  for  catastrophic  maternal  and  fetal  complications.  Stroke  is  defined  as  an  acute  neurological  insult  resulting  from  obstruction  or  rupture  within  the  cerebral  vascular  system  not  caused  by  tumor  or  trauma.  Stroke,  also  known  as  cerebrovascular  accident  (CVA),  is  based  on  a  hemorrhagic  or  ischemic  etiology.  Hemorrhagic  stroke  includes  intracerebral  hemorrhage  (ICH)  and  subarachnoid  hemorrhage  (SAH).  Commonly,  hemorrhagic  strokes  are  the  result  of  a  structural  disruption  of  cerebral  vasculature  and  are  associated  with  malignant  or  uncontrolled  hypertension,  arteriovenous  malformation  (AVM)  rupture,  or  cerebral  aneurysm  rupture.  Ischemic  CVA  develops  after  hypoperfusion  or  disruption  of  cerebral  blood  flow  and  leads  to  focal  vascular  obstruction.  Most  ischemic  strokes  result  from  arterial  occlusion.  Less  frequently,  ischemic  events  are  secondary  to  venous  thrombosis,  paradoxical  embolus,  or  cardioembolism.  Systemic  hypoperfusion  from  peripartum  cardiomyopathy,  arterial  hypotension,  cardiac  arrhythmias,  and  cervical  artery  dissection  of  carotid  or  vertebral  arteries  may  also  lead  to  reduced  cerebral  perfusion  and  precipitate  an  ischemic  etiology.1  Transient  ischemic  attacks  are  temporary  disruptions  in  blood  flow  with  symptoms  lasting  less  than  24  hours  but  portend  an  increased  lifetime  risk  of  CVA.2
