title: Giant celiac artery aneurysm: Treatment by transcatheter coil embolization.
abstract: Celiac artery aneurysms (CAA) are one of the rarest forms of visceral artery aneurysms. Most patients are a symptomatic at the time of diagnosis and aneurysms are detected incidentally during diagnostic imaging for other diseases. We present the case of a 42-year-old man who had an asymptomatic giant CAA detected incidentally by an abdominal ultrasound investigating an abdominal pain. A contrast enhanced computed tomography angiogram (CTA) revealed a large CAA measuring 7.1 cm × 4.3 cm with extensive collaterals from the superior mesenteric artery (SMA). The aneurysm sac was mostly filled with thrombus with the celiac artery branches occluded. Pre-procedural angiography and transcatheter embolization procedures were performed at the same session. Endovascular exclusion was performed by transcatheter coil embolization and packing of the aneurysm sack. Technical success was achieved by the absence of flow in the aneurysm, and preservation of the native circulation on angiograms obtained just after the transcatheter coil embolization procedure. One week postembolization, a CTA confirmed thrombosis of the aneurysm. The patient returned for a follow-up CTA 3, 6, 12 and 48 months after embolization. The aneurysm was thrombosed and the patient remained a symptomatic. The surgical mode of treatment of CAA is increasingly being replaced by endovascular embolization because of the lower morbidity and mortality and high success rate. The accepted endovascular approach is by coil embolization of the aneurysmal lumen, the proximal and distal aneurysmal neck, or both.
