Abstract

We encountered a case of complex isolated spontaneous celiac artery dissection with a patent false lumen with both entry and re-entry and extensive aneurysmal degeneration of the splenic artery. The dissection entry was wide and was located at the origin of the celiac artery. The false lumen extended to the distal part of the splenic artery, obstructed the true lumen, and was connected to the true lumen at the splenic hilum via the re-entry. Treatment was successful by stent-graft placement for the occlusion of the entry and embolization of the re-entry with microcoils via the false lumen of the splenic artery.

Keywords: embolization; isolated spontaneous celiac artery dissection; stent-graft placement.
