Superior Mesenteric Artery Syndrome with Abdominal Compartment Syndrome

Abstract EN

Superior Mesenteric Artery (SMA) syndrome is a condition in which the duodenum becomes compressed between the SMA and the aorta, resulting in bowel obstruction which subsequently compresses surrounding structures.

Pressure on the inferior vena cava (IVC) and aorta decreases cardiac output which compromises distal blood flow, resulting in abdominal compartment syndrome with ischemia and renal failure.

A 15-year-old male with SMA syndrome presented with 12 hours of pain, a distended, rigid abdomen, mottled skin below the waist, and decreased motor and sensory function in the lower extremities.

Exploratory laparotomy revealed ischemic small bowel and stomach with abdominal compartment syndrome.

Despite decompression, the patient arrested from hyperkalemia following reperfusion.
