Splenic Artery Aneurysm in Pregnancy.

Background: Splenic artery aneurysm (SAA), a rare condition chiefly affecting women, poses significant challenges for management when it occurs during pregnancy. Reports of successful management of SAA before rupture in pregnancy are limited, with several post-rupture cases reported.

Case: We describe the case of a woman with an SAA of 13 × 9 mm near the hilum of the spleen who subsequently became pregnant. Embolization of the splenic artery in the third trimester resulted in occlusion of the aneurysm but was followed three weeks later by a splenic abscess. The patient went on to deliver a healthy baby.

Conclusion: This case illustrates the importance of maintaining awareness of SAA in pregnancy because the condition carries a high risk of rupture and hemorrhage with high rates of fetal and maternal mortality.
