A case of a patient who underwent transcatheter arterial embolization for unruptured splenic aneurysm during pregnancy.

Here, we report the case of a 30-year-old female patient who underwent coil embolization for unruptured splenic artery aneurysm without any complication at 26 weeks of pregnancy with reduction in fetal radiation exposure. The patient did not suffer from rupture of splenic artery aneurysm during or after procedure. Pregnancy is a risk factor of splenic artery aneurysm rupture with a high mortality rate. Transcatheter arterial embolization at 26 weeks of pregnancy might be a better treatment alternative for a pregnant patient with splenic artery aneurysm with respect to the endurance of fetal radiation exposure to prevent aneurysm rupture.
