Introduction: Stroke is one of the main agents of mortality in advanced societies. Brain ischemia is a destructive phenomenon for pregnant women; because this phenomenon can lead to death or long-term disability and affect the family as well as the not born child. It is important to note that patterns of stroke affecting pregnant women differ from the non-pregnant female population at childbearing age.
Methods: This review study, conducted in 2020, includes articles were from Pub med, Scopus, Web of Science, and Google Scholar databases. Articles that did not have sufficient information about sub-types of stroke were excluded from the study.
Results: Hemorrhagic strokes and ischemic strokes are the most common types of stroke in pregnant women. Among the ischemic strokes, the highest was arterial occlusions, and then venous occlusions. The most common cause of arterial occlusions was cerebral vasoconstriction syndrome. Major causes of hemorrhage were aneurysm, then arterial-venous malformation, pregnancy-induced hypertension, and HELLP syndrome [hemolysis, the H in the acronym, elevated liver enzymes (EL), and low platelet count (LP)]. Hemorrhagic stroke revealed a much weaker forecast and with less abundance than ischemic stroke. Hyper-coagulable, pre-eclampsia, and thrombo-embolic diseases with elevated pro-thrombotic biomarkers and increased cerebrovascular disease were less frequent than the other two diseases.
Conclusion: There are different types of stroke-related to pregnancy. Ischemic stroke is the most common type of stroke among pregnant women. The existence of cerebrovascular diseases and cerebral vasoconstriction play an important role in Ischemic stroke and hemorrhage stroke.
