Area of Science:

  • Vascular Surgery
  • Abdominal Imaging
  • Gastroenterology

Background:

  • Isolated spontaneous superior mesenteric artery dissection (ISMAD) is an exceedingly rare vascular emergency.
  • ISMAD presents with nonspecific abdominal pain, often delaying diagnosis and treatment.
  • Prompt recognition and management are crucial to prevent fatal complications.

Observation:

  • A 51-year-old male presented with severe epigastric pain.
  • Computed tomography (CT) scan revealed superior mesenteric artery dissection.
  • The patient had no predisposing factors for arterial dissection.

Findings:

  • The patient was successfully treated with a conservative management strategy.
  • Conservative treatment included bowel rest, beta-blockers, and anticoagulation.

  • This approach effectively managed the dissection without surgical intervention.

    • Implications:

    • Highlights the importance of considering ISMAD in patients with unexplained abdominal pain.
    • Demonstrates the efficacy of conservative management for select ISMAD cases.
    • Emphasizes the need for timely diagnosis via advanced imaging like CT angiography.
