Moniz sign
Moniz Sign is a clinical sign in medicine that indicates the presence of an abdominal aortic aneurysm. It is named after the Portuguese neurologist António Egas Moniz.
Definition[edit | edit source]
The Moniz Sign is defined as the presence of a pulsatile mass in the abdomen that is not transmitted through the aorta. This sign is often associated with an abdominal aortic aneurysm, a condition characterized by an enlargement of the aorta, the main blood vessel that delivers oxygenated blood to the circulatory system, in the abdomen.
Clinical Significance[edit | edit source]
The presence of Moniz Sign can be a crucial indicator of an abdominal aortic aneurysm. This condition can lead to life-threatening complications if not detected and treated promptly. The sign can be detected during a physical examination, where the healthcare provider may feel a pulsating mass in the abdomen.
History[edit | edit source]
The Moniz Sign is named after António Egas Moniz, a Portuguese neurologist and the winner of the Nobel Prize in Physiology or Medicine in 1949. Moniz is also known for his work in the development of cerebral angiography and prefrontal leucotomy.
