Technical Considerations and Clinical Outcomes in the Endovascular Management of Celiac Arterial Aneurysms

This retrospective case series details a single-center experience of 8 patients (mean age, 54.4 years) with celiac artery aneurysms (CAAs) who underwent 1 parent vessel-sparing, 5 partial parent vessel-sparing, and 2 non-parent vessel-sparing procedures. Technical success was achieved in 6 of 8 (75%) patients. Both technical failures arose from type II endoleaks, which spontaneously resolved, resulting in clinical success of all cases. In-stent restenosis requiring reintervention complicated 3 of 5 (60%) partial parent vessel-sparing techniques, with 2 of 3 developing complete thrombosis. Two Society of Interventional Radiology grade C complications were recorded, none of which resulted in permanent sequelae. The endovascular management of CAAs is safe and amenable to various techniques.
