Mesenteric Artery Stenosis

What is Mesenteric Artery Stenosis?

Mesenteric artery stenosis is the narrowing of the arteries supplying blood to the intestines. In most cases the stenosis is caused by atherosclerosis or hardening of the arteries, the same process that is responsible for most strokes and heart attacks.

Narrowing of the mesenteric arteries can lead to unexplained weight loss and abdominal pain after eating. One or more of the following imaging tests may be used to determine the location and the extent of the arterial narrowing (stenosis):

What Treatment Options are Available?

Asymptomatic patients with mesenteric artery stenosis may be treated with lifestyle modifications like smoking cessation, regular exercise and management of related conditions such as diabetes, high blood pressure and high cholesterol. However, in many cases, a procedure may be recommended to relieve the narrowing in the artery and restore blood flow to the involved organ. The arterial stenosis can often be treated using minimally invasive procedures such as angioplasty and stenting. If the stenosis is not amenable to angioplasty, arterial bypass surgery may necessary in order to restore blood flow.
