The laparoscopic approach in the median arcuate ligament syndrome: report of a case.

A malposition of the median arcuate ligament (MAL) is a rare entity causing the celiac axis compression syndrome (CACS), first described by Harjola in 1963. The presence of anomalous fibrous diaphragmatic bands of the diaphragm compresses the celiac axis, especially during the expiration. In this report we present the fourth case in literature that was ever successfully treated by laparoscopy. A 38-year-old male presented with a history of intermittent epigastric pain, 15 kg weight loss caused by inappetence and frequent diarrhoea, over a 5-year period. The clinical examination revealed only a loud systolic bruit in the epigastrium, with loss of intensity during deep inspiration. Suspecting CACS, a spiral CT angiography was requested. The CT demonstrated the MAL crossing anteriorly to the celiac artery (CA) and the sagittal and the tridimensional reconstructions demonstrated the CA narrowing due to compression, while the superior mesenteric artery (SMA) was normal. The MAL was laparoscopically divided, releasing the celiac axis. The surgical time was 130 minutes, without significant blood losses. At 3-months follow-up, the CT-scan demonstrated no evidence of CACS with complete recovery.
