Pregnancy-related strokes are often arterial occlusions, predominantly occurring in the third trimester or postpartum. While all infarction patients survived, some hemorrhage cases were fatal.

Area of Science:

  • Neurology
  • Obstetrics
  • Vascular Medicine

Background:

  • Stroke during pregnancy and the postpartum period is a rare but serious complication.
  • Characterizing these events is crucial for timely diagnosis and management.

Purpose of the Study:

  • To characterize stroke subtypes associated with pregnancy and the puerperium.
  • To analyze the timing, etiology, risk factors, and outcomes of these strokes.

Main Methods:

  • Retrospective analysis of 34 patients with stroke during pregnancy or within 6 weeks postpartum.
  • Stroke classification into ischemic (arterial/venous) and hemorrhagic (subarachnoid/intracerebral).
  • Diagnostic imaging included CT, MRI, and cerebral angiography.

Main Results:

Related Experiment Videos

  • 21 infarctions (13 arterial, 8 venous) and 13 hemorrhages (7 subarachnoid, 6 intracerebral) were identified.
  • Arterial occlusions mostly occurred in the third trimester/puerperium; venous occlusions were predominantly postpartum.
  • Etiologies included cardiac emboli, coagulopathies, carotid artery dissection, ruptured aneurysms, arteriovenous malformations, and disseminated intravascular coagulation.

Conclusions:

  • Arterial occlusions represent the majority of pregnancy-associated strokes.
  • These events most frequently present during the third trimester and the puerperium.
  • Outcomes varied, with all infarction patients surviving but some hemorrhage patients dying.
