case_images: Fig. 1 (A) Preoperative enhanced CT showed a 2.4-cm dissected SMA aneurysm (arrow). (B) Three-dimensional CT. CT: computed tomography; SMA: superior mesenteric artery.

case_images: Computed tomography (CT) revealed an SMA aneurysm that had rapidly enlarged from 11 to 24 mm in 1 year (Fig. 1).
case_images: Fig. 2 (A) Pre-implantation of stent-graft angiography showed SMA aneurysm (arrows). (B) Completion angiography showed exclusion of the aneurysm preservation of the middle colic artery as well as the distal branches of the SMA with no endoleak (arrows). SMA: superior mesenteric artery.

case_images: The post-stenting angiogram of the SMA demonstrated preservation of the distal branches of the SMA with no endoleak (Figs. 2A and 2B).
case_images: Fig. 3 (A) Postoperative CT showed exclusion of the aneurysm, patent stent-graft, and preservation of the middle colic artery as well as the distal branches of the SMA with no endoleak. (B) Postoperative echo at 3-year follow-up showed patent stent-graft of SMA. CT: computed tomography; SMA: superior mesenteric artery.

case_images: At the time of this writing, the patient had remained free of symptoms for 3 years after the procedure, and follow-up CT (Fig. 3A) and ultrasound (Fig. 3B) confirmed successful exclusion of the aneurysm with no endoleak.
