An isolated spontaneous dissecting celiac artery aneurysm with successful endovascular treatment using stenting and coil embolization.

Isolated spontaneous dissecting celiac artery aneurysm (DCAA) is a rare event. We report the case of a 50-year-old Japanese man with sudden post-prandial epigastric pain. He was diagnosed as having an isolated DCAA based on the results of contrast-enhanced multi-slice computed tomography (CT). Initially, we gave him conservative therapy, but the aneurysm grew and then we performed endovascular treatment. The DCAA did not cause a rupture, and there were rich collateral channels between the superior mesenteric artery and the common hepatic artery. However, the neck of the aneurysm was too broad to indwell coils, and it was thought that coils might drop out from the aneurysm. We chose endovascular therapy with a self-expanding stent and coil embolization, and the aneurysm was extinguished. He was successfully treated and has recovered favorably. To our knowledge, few cases of a DCAA treated with both a self-expanding stent and coil embolization have been reported and this strategy may be one of the endovascular treatment options for a DCAA. More data accumulation of this method and investigation of long-term treatment effect are required in the future. <Learning objective: A dissecting celiac artery aneurysm is a rare event. Conservative, endovascular, and surgical therapies have been described, but no optimum treatment exists. For the present patient, we chose endovascular therapy with a stent and coil embolization, and he was successfully treated. To our knowledge, few cases of this condition treated with both stenting and coiling have been reported. We suggest that this strategy be one of the endovascular treatment options for this condition.>.
