Superior Mesenteric Artery (SMA) Syndrome – When the Intestine Gets Compressed Between Two Arteries
A Rare Cause of Severe Digestive Problems and Rapid Weight Loss
Persistent vomiting, severe fullness after meals, and unexplained weight loss may sometimes be due to a rare digestive condition called Superior Mesenteric Artery (SMA) Syndrome.
This condition occurs when the third part of the duodenum (part of the small intestine) becomes compressed between two major blood vessels — the aorta and the superior mesenteric artery. The compression blocks the normal passage of food, causing symptoms similar to intestinal obstruction.
At Aayush Multispeciality Hospital, rare gastrointestinal conditions like SMA syndrome are carefully evaluated and treated under the expertise of Dr. Ankur Bhanushali, a highly experienced General and Advanced Laparoscopic Surgeon in Thane known for advanced laparoscopic gastrointestinal surgeries.
What Is Superior Mesenteric Artery (SMA)?
The Superior Mesenteric Artery is a major blood vessel that:
- Supplies blood to the small intestine
- Supplies part of the large intestine
- Branches from the abdominal aorta
Normally, there is a cushion of fat between the artery and the intestine. When this fat pad becomes reduced, the artery compresses the duodenum.
What Causes SMA Syndrome?
SMA syndrome often develops when there is rapid or severe weight loss, which reduces the protective fat layer around the artery.
Common causes include:
- Severe weight loss
- Eating disorders
- Chronic illness
- Major trauma
- Spinal surgery
- Prolonged bed rest
- Severe burns
Young individuals with sudden weight loss are particularly at risk.
Symptoms of SMA Syndrome
Symptoms usually worsen after meals and may include:
✔ Persistent vomiting after eating
✔ Severe fullness after small meals
✔ Upper abdominal pain
✔ Nausea
✔ Rapid weight loss
✔ Loss of appetite
Many patients avoid eating because it worsens their symptoms.
Why Is It Often Misdiagnosed?
Because the symptoms resemble many common digestive conditions, SMA syndrome may be mistaken for:
- Gastritis
- Peptic ulcer disease
- Acid reflux
- Functional dyspepsia
- Intestinal obstruction
Without proper imaging, the condition can remain undiagnosed for a long time.
How Is It Diagnosed?
Diagnosis usually involves imaging tests such as:
- CT scan of the abdomen
- CT angiography
- Upper GI contrast study
- Ultrasound in selected cases
CT scans can measure the angle between the aorta and the superior mesenteric artery, confirming the diagnosis.
Complications If Untreated
If ignored, SMA syndrome can lead to:
- Severe malnutrition
- Chronic dehydration
- Electrolyte imbalance
- Persistent vomiting
- Intestinal obstruction
Timely treatment is essential to restore normal digestion.
Treatment of SMA Syndrome
Treatment depends on the severity of symptoms.
1️⃣ Conservative Treatment
In early cases, treatment may include:
- Nutritional support
- High-calorie diet
- Weight gain programs
- Intravenous fluids
- Small frequent meals
The goal is to restore the protective fat pad around the artery.
2️⃣ Surgical Treatment
If symptoms persist despite conservative treatment, surgery may be required.
The most common surgical procedure is:
Duodenojejunostomy
This surgery bypasses the compressed portion of the intestine, allowing food to pass normally.
