Superior mesenteric artery (SMA) aneurysms are rare but prone to rupture. This case highlights successful management of a rapidly progressing SMA aneurysm, emphasizing diagnostic and treatment strategies.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Gastroenterology

Background:

  • Superior mesenteric artery (SMA) aneurysms are uncommon, representing 8% of visceral artery aneurysms.
  • These aneurysms carry a high risk of rupture, regardless of size, posing significant management challenges.
  • A notable proportion (50-60%) of SMA aneurysms are mycotic, influencing surgical approach selection.

Observation:

  • The study presents a case of a superior mesenteric artery aneurysm identified during impending rupture.
  • The patient underwent successful treatment for the condition.

Findings:

  • Successful management of a superior mesenteric artery aneurysm diagnosed at the point of imminent rupture.
  • Discussion of the etiology, presentation, diagnosis, and management strategies for SMA aneurysms.

Implications:

  • Highlights the critical need for prompt diagnosis and intervention in cases of suspected SMA aneurysm.
  • Informs surgical decision-making, particularly for mycotic aneurysms.
  • Contributes to understanding the rare but dangerous nature of visceral artery aneurysms.
