Summary
Isolated superior mesenteric artery dissection (ISMAD) is rare. This case highlights blunt abdominal trauma as a potential, previously unreported cause of ISMAD, leading to intestinal ischemia.
Area of Science:
- Vascular Surgery
- Gastroenterology
- Trauma Surgery
Background:
- Isolated superior mesenteric artery dissection (ISMAD) is an uncommon condition.
- ISMAD can present with varied symptoms, from asymptomatic cases to acute intestinal ischemia.
- Known risk factors include hypertension, atherosclerosis, abnormal elastic fibers, and pregnancy.
Observation:
- A 46-year-old male presented after a motor vehicle collision with no initial abdominal symptoms.
- On the fourth day, he developed severe abdominal pain and vomiting.
- A contrast-enhanced CT scan confirmed ISMAD with associated intestinal ischemia and necrosis.
Findings:
- Blunt abdominal trauma, a novel risk factor, is implicated in this case of ISMAD.
- The patient required emergency surgery due to the severity of the condition.
Implications:
- This case expands the known etiology of ISMAD to include blunt force trauma.
- Awareness of trauma as a potential cause is crucial for timely diagnosis and management of ISMAD.
- Further research may be warranted to explore the mechanisms linking trauma to arterial dissection.
