Since 2009, thoracic aortic stent graft treatment (TEVAR) using a less invasive catheter has been available in Japan for thoracic aortic aneurysms created in the descending aorta. However, how to preserve some of the celiac arteries in the descending aorta is an important issue. If the arcade from the superior mesenteric artery can be preserved, the hepatic artery and splenic artery can be preserved by embolizing only the origin of the celiac artery. Here, we report a case in which the origin of the celiac artery was completely embolized with hydrogelcoated coil in balloon assisted coil embolization (BACE) with thoracic endovascular aortic aneurysm repair.
