Hepatic artery aneurysm

A hepatic artery aneurysm is a rare but potentially life-threatening condition characterized by an abnormal dilation of the hepatic artery, which supplies oxygen-rich blood to the liver.

This condition involves the weakening of the arterial wall, leading to a balloon-like bulge.

While hepatic artery aneurysms are uncommon, they represent the second most common type of visceral artery aneurysm, following splenic artery aneurysms.

The liver is a vital organ, and its blood supply is essential for processing nutrients, detoxifying harmful substances, and producing proteins necessary for blood clotting.

A rupture of a hepatic artery aneurysm can lead to severe internal bleeding and requires immediate medical intervention.

Etiologies of hepatic artery aneurysms include atherosclerosis, infection, trauma, and connective tissue disorders.

Symptoms can vary; some patients may be asymptomatic, while others might experience abdominal pain, jaundice, or gastrointestinal bleeding.

Diagnosis is often made via imaging studies such as ultrasound, CT angiography, or MRI, which can provide details about the size and exact location of the aneurysm.

Treatment options depend on the size and risk of rupture and may include surgical repair or endovascular techniques such as stenting or embolization.

Early detection and management are crucial to prevent complications, and ongoing monitoring may be necessary for smaller aneurysms that are not immediately treated.

Patients with risk factors for vascular disease should be particularly vigilant and seek regular medical evaluations.
