Endovascular Treatment of Ruptured Blister Aneurysm With Flow Diverter Stents in Pregnancy

Pregnancy-related physiological changes may contribute to SAH risk, including increased cardiac output occurring from the beginning of the third trimester, exposure to the pregnancy-related hormones and pregnancy-related hypertensive disorders.2 Pregnancy itself is very uncommon risk factor for dissection, which are most often noticed in the third trimester or postpartum period and exclusively in the extracranial circulation.3,4 Other typical risk factors for craniocervical artery dissection (CAD) are major or minor trauma, cervical manipulation, violent coughing, genetic connective tissue disorder etc, but there are multiple reports suggesting association between recurrent vomiting and CAD in the literature.5 We hypothesize that the recurrent vomiting due hyperemesis gravidarium contributed to the development of arterial dissection in our patient. [...]aneurysmal SAH in the first trimester of pregnancy is unusual. [...]blister aneurysms involving the anterior circulation and it’s treatment with the flow-diverting stent in pregnancy have not been previously reported.
