The case of a 60-year-old woman with a ruptured splenic artery aneurysm is presented. She arrived at our hospital with severe abdominal pain and in shock. After resuscitation, angiography revealed a splenic artery aneurysm measuring 5cm×3cm at the distal portion of the splenic artery and perihepatosplenic fluid collection. Her vital signs were stable, so we attempted TAE for the ruptured splenic artery aneurysm. First of all, we occluded the root of the splenic artery using a balloon catheter. Next, we allowed the microcatheter to pass through the balloon catheter and the aneurysm, and we implanted 16 microcoils from the distal to the proximal side of the splenic artery aneurysm. Complete TAE of the splenic artery aneurysm was confirmed by post TAE angiography. This TAE using a balloon catheter and a microcatheter for ruptured splenic artery aneurysm was considered to be safe and effective.
