Superior Mesenteric Artery Syndrome: Symptoms, Causes, and Treatment

Superior Mesenteric Artery Syndrome (SMAS) occurs when the duodenum is compressed between the superior mesenteric artery and the aorta, leading to gastrointestinal issues. It's significant as it can cause severe symptoms like abdominal pain, vomiting, and weight loss. Although rare, SMAS prevalence is estimated at around 0.01%-0.3%. If you or someone you know experiences persistent abdominal discomfort or unexplained weight loss, consulting a healthcare provider is crucial for timely diagnosis and management.

Causes of Superior Mesenteric Artery Syndrome

Main Factors Contributing to Superior Mesenteric Artery Syndrome:

• Abnormal angle between the aorta and superior mesenteric artery.
• Rapid weight loss leading to reduced fat pad around the artery.
• Severe scoliosis which compresses the artery.
• Prolonged bed rest causing weakening of abdominal muscles.

Symptoms of Superior Mesenteric Artery Syndrome

Recognizing the symptoms of Superior Mesenteric Artery Syndrome (SMAS) is crucial as early detection can significantly improve outcomes. Being aware of the signs can prompt timely medical intervention, preventing complications and improving quality of life.

Common symptoms of Superior Mesenteric Artery Syndrome include:

• Severe abdominal pain after eating
• Nausea and vomiting
• Weight loss
• Abdominal bloating
• Early satiety (feeling full quickly)
• Malabsorption of nutrients

Diagnosis of Superior Mesenteric Artery Syndrome

Accurate diagnosis of Superior Mesenteric Artery Syndrome is crucial as it can mimic other gastrointestinal conditions, leading to misdiagnosis and delayed treatment. The diagnostic process typically involves a combination of medical history review, physical examination, and imaging tests. Imaging studies play a key role in confirming the diagnosis. Common diagnostic methods include:

• Barium swallow studies
• CT scans
• Upper gastrointestinal endoscopy
