Median arcuate ligament syndrome: A rare case report from Nepal.

INTRODUCTION

Median arcuate ligament syndrome (MALS) is a rare condition caused by the compression of the celiac trunk by the median arcuate ligament, leading to a typical symptom triad: postprandial abdominal pain, weight loss, nausea, and vomiting.

CASE PRESENTATION

A 41-year-old female patient presented to our center with mild postprandial abdominal pain over the epigastric region, and bloating sensation. Ultrasonography of the abdomen showed multiple stones in the gall bladder lumen, and the computed tomography scan showed median arcuate ligament impingement along the proximal aspect of the celiac trunk causing moderate narrowing with post-stenotic dilation. Laparoscopic release of the median arcuate ligament with laparoscopic cholecystectomy was performed.

DISCUSSION

The diagnosis of Median Arcuate Ligament Syndrome is based on the classical post-prandial symptoms and abdominal imaging technologies like Doppler ultrasonography, computed tomography angiography, or magnetic resonance angiography. Exclusion of other intestinal disorders should be considered before making the diagnosis. Celiac artery decompression through different means is the principle of treatment of this condition.

CONCLUSION

The diagnosis of median arcuate ligament syndrome should be considered in patients with postprandial abdominal pain that does not have an established etiology. Celiac artery decompression by releasing the median arcuate ligament is the treatment.
