Abstract
Cerebral arteriovenous malformation (AVM) in pregnancy is a complex situation and there is no agreement on its hemorrhage risk and treatment. Although studies on bleeding risk of cerebral AVMs in pregnancy are very few and there are different results between them, pregnancy will increase the hemorrhagic risk of AVM, and ruptured cerebral AVM in pregnancy should be treated actively. After intracranial hemorrhage, cerebral angiography should be performed for pregnant women shielded correctly. Cerebral angiography could clearly demonstrate the characteristics of cerebral AVM. The results from the literature show that the radiation dose of endovascular and stereotactic radiotherapy for cerebral AVM in pregnancy is below the safety value and is safe. Unruptured AVM in pregnancy, if there is no bleeding factor, such as no coexisting aneurysm, smooth venous drainage, no venous ectasia, or high risk of treatment, should be observed conservatively.
