The organ arteries (visceral vessels) supply the internal organs, e.g. the kidneys, the intestine and the liver, with oxygen-rich blood. Various risk factors, such as smoking, elevated blood lipid levels or hereditary predisposition, can lead to the narrowing (stenosis) or widening (aneurysms) of the organ arteries. With an increased narrowing (stenosis) of the vessels, there is a risk that the affected organs can no longer be adequately supplied with blood. What then follows ranges from organ damage up to the loss of the organ with fatal consequences. The rare enlargement (aneurysms) of organ arteries can lead to the bursting of the affected vessel with the risk of life-threatening internal bleeding.
The diagnosis of organ artery disease is carried out primarily through ultrasound or computerized tomography, either due to particular symptoms or, as often in the case of vasodilations, incidental findings.
