Superior mesenteric artery aneurysm

A superior mesenteric artery aneurysm is a rare vascular condition characterized by the abnormal dilation of the superior mesenteric artery (SMA), which is a major artery that supplies blood to the intestines.

This condition is considered a type of splanchnic artery aneurysm, and it predominantly affects the abdomen region.

The superior mesenteric artery branches off from the abdominal aorta and supplies oxygen-rich blood to the majority of the small intestine, as well as parts of the large intestine and pancreas.

An aneurysm in this artery can pose significant risks, including the potential for rupture, which can lead to life-threatening internal bleeding and compromised blood flow to the intestines.

Symptoms of an SMA aneurysm may be non-specific or absent until complications arise, making early detection challenging.

When symptoms do occur, they may include abdominal pain, nausea, vomiting, and signs of gastrointestinal bleeding.

Advanced imaging techniques, such as CT angiography or MRI, are vital for accurate diagnosis and assessment.

Treatment for a superior mesenteric artery aneurysm often depends on the size and risk of rupture.

Options may include surgical repair or endovascular interventions to prevent complications.

Continuous monitoring and follow-up care are essential to manage this condition effectively.
