Median Arcuate Ligament Syndrome - Signs and Symptoms

Signs and Symptoms

Patients with MALS reportedly experience abdominal pain, particularly in the epigastrium, which may be associated with eating and which may result in anorexia and weight loss. Other signs are persistent nausea, lassitude (especially after a heavy meal) and exercise intolerance. Exercise or certain postures can aggravate the symptoms. Occasionally, physical examination reveals an abdominal bruit in the mid-epigastrium.

Complications of MALS result from chronic compression of the celiac artery. They include gastroparesis and aneurysm of the pancreaticoduodenal arteries.

Famous quotes containing the words signs and/or symptoms:

    Wherever I look, I see signs of the commandment to honor one’s parents and nowhere of a commandment that calls for the respect of a child.
    Alice Miller (20th century)

    There is one great fact, characteristic of this our nineteenth century, a fact which no party dares deny. On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant with its contrary.
    Karl Marx (1818–1883)
