Rupture of a Splenic Artery Aneurysm in the First Trimester of Pregnancy

Background: Rupture of a splenic artery aneurysm during pregnancy is a rare and serious event, occurring mainly during the third trimester. The risk of rupture for an existing splenic artery aneurysm is very high during pregnancy (from 20% to 50%). When it does rupture, the maternal mortality rate is around 75% and the fetal mortality rate 95%. Of 110 cases reported in the literature, only one ruptured during the first trimester. Objectives: The aim of this case report is to make emergency physicians aware of this diagnosis, because only if it is considered can it be managed rapidly and appropriately. Case Report: We report the case of a 6-weeks pregnant patient referred to our institution in hemorrhagic shock who died of a ruptured splenic artery aneurysm shortly after surgery. The initial diagnosis considered was a ruptured ectopic pregnancy. Conclusion: We report this case to increase awareness of splenic artery rupture during pregnancy, even during the first trimester.
