Abstract

Introduction: Digestive arterial aneurysms are rare. The splenic artery aneurysm (SA) is the most common visceral artery aneurysm (60% of
cases). The origin of SA from the superior mesenteric artery (SMA) is an exceptional anatomical variation. The rupture of this aneurysm leads to
death in 10 to 25% of cases.
Observation: This is a 40-year-old adult presenting with abdominal pain associated with fever. An abdominal ultrasound shows a vascular mass
projecting into the celiac region. CT angiography shows an aneurysm of SA. The patient is operated on and benefits from selective ligation and
resection of the aneurysm with preservation of the spleen. The nascent SA of the SMA has been respected. The immediate postoperative course
was simple. The abdominal pain stopped. The patient was placed under medical supervision externally.
Conclusion: These arterial aneurysms should be followed regularly and should be treated by conventional surgery or better by endovascular
procedure when the technical means are available.

Keywords:
