An aneurysm occurs when a portion of the artery widens, due to a weakness in the blood vessel wall. Symptoms differ, depending on where the aneurysm occurs. Doctors perform physical exams and diagnostic tests to determine whether an aneurysm exists. In many cases, surgery can correct the problem when the aneurysm has not ruptured. If the aneurysm has ruptured, the probability of death is high, according to MedlinePlus. Knowing the symptoms helps identify problems.
Brain Aneurysm
MedlinePlus reports that approximately 5 percent of the population has some sort of brain aneurysm. Certain medical conditions, such as polycystic kidney disease and a family history of cerebral aneurysms increase risks.
Typically no symptoms exist with brain aneurysms; however, a ruptured aneurysm causes bleeding in the brain and can lead to severe headache, vision disturbances, eye or neck pain. Prompt medical treatment is necessary to prevent further bleeding and to control symptoms. Mayo Clinic.com notes that about half of these cases are fatal.
Aortic Aneurysm
An aortic aneurysm occurs in the aorta, the body's major blood vessel running from the heart through the chest and abdomen. Small, slow-growing aortic aneurysms do not rupture or produce symptoms. However, aortic aneurysms that grow rapidly are more likely to rupture and cause symptoms like pulsating in the naval, pain in the abdomen, chest or back.
Mayo Clinic.com reports that while aneurysms can arise any place along the aorta, most occur in the abdomen. Occasional screenings are recommended for those with risk factors.
Shock
Shock is a severe symptom that occurs when the organs do not get enough oxygen or blood. This can develop with an aneurysm.
A person who is in shock may become pale or grey. His pupils dilate and he becomes nauseated, which may cause him to vomit. Confusion, anxiety and loss of consciousness can also occur. Changes in heart rate and breathing are other signs. Mayo Clinic.com advises calling 911 or a local emergency number if these symptoms arise.
