A murmur formed by the abdominal vessels: 1. There is a narrowing of the abdominal vessels. 2. entrapment. 3. aneurysm. 4. increased pressure in the abdominal vessels. Murmurs are difficult to detect and identify by auscultation. Experienced physicians can hear the abnormality, but are unable to distinguish what kind of disease it is. Most of the murmurs are only systolic wind-like murmurs, and the specific diagnosis needs to rely on angiography or abdominal CT to make a clear diagnosis. Various vascular diseases do not require treatment if they are asymptomatic, but should be treated aggressively if they produce ischemia in the lower tissues and organs. In case of large clips or aneurysms, rupture and hemorrhage are very difficult to save, and larger aneurysms may compress the tissues in the upper periphery to produce pain, which is manifested as limited epigastric pain, and bleeding from aneurysms may enter the gastrointestinal tract, which may cause vomiting of blood, black stools, or enter the abdominal cavity to cause acute abdominal syndrome, and surgery should be the main treatment for higher risk factors.
