Some common locations for aneurysms include: Aorta (the major artery from the heart) see abdominal aortic aneurysm and thoracic aortic aneurysm Brain ( cerebral aneurysm Leg (popliteal artery aneurysm) Intestine (mesenteric artery aneurysm) Splenic artery aneurysm Causes, incidence, and risk factors Return to top Aneurysms are either congenital (present before birth) or acquired. It is not clear exactly what causes aneurysms. Defects in some of the components of the artery wall may be responsible. In certain cases (abdominal aortic aneurysms), high blood pressure is thought to be a contributing factor. Atherosclerotic disease (cholesterol buildup in arteries) may contribute to the formation of certain types of aneurysms. Pregnancy is often associated with the formation and rupture of aneurysms of the splenic artery (an artery leading to the spleen).

(AP Photo/Julie Jacobson) NEW YORK - Neil Young was treated for a brain aneurysm this week and remains hospitalized, although doctors expect a full recovery, his publicist said Friday. The 59-year-old rocker underwent a procedure to treat it Tuesday night at a New York hospital, where he was expected to remain for a few more days, publicist Bob Merlis told The Associated Press. Dr. Pierre Gobin, who performed the procedure with another doctor, said: "Mr. Young had a dangerous brain aneurysm and was treated successfully by the minimally invasive neuroradiology team here. He is now resting comfortably ... but we strongly recommend that he not travel for several days." Grammys "I'm really disappointed that I won't be able to make it to Winnipeg for the Junos as I had hoped. I grew up there and was really looking forward to the show as well as spending some time with my old friends and family," Young said. "Thanks to my doctors, I'm feeling a lot better now so I hope I can get a rain check."

F amilial I ntracranial A neurysm (FIA) Study WHAT IS THE FIA STUDY? The Familial Intracranial Aneurysm Study, also known as the FIA study, is a collaborative research effort of neurologists and neurosurgeons throughout the United States Canada Australia and New Zealand . The goal of this study is to identify genes that may be important in the development of intracranial aneurysms. This study is sponsored by the National Institutes of Neurologic Diseases and Stroke and will involve 475 families with multiple affected family members throughout North America Australia and New Zealand WHAT ARE INTRACRANIAL ANEURYSMS: Intracranial aneurysms are “blisters” which form within the arteries at the base of the brain. A rupture of an aneurysm may lead to subarachnoid hemorrhage. (SAH) Symptoms of SAH include sudden: Severe headache Loss of consciousness Pain in neck, back, eye or face Nausea and vomiting Photophobia (Sensitivity to light) Phonophobia (Sensitivity to sound) The mortality rates of patients suffering from a SAH is 40 – 44%, with many survivors suffering major disability. Most of the deaths from SAH are due to rapid and massive brain injury from the initial bleeding, which is not correctable by medical and surgical intervention. Thus prevention of aneurysm formation is of paramount importance.

Aneurysm Aneurysm: a sac formed by localized dilatation of an artery or vein Thoracic aortic aneurysm: In this disorder, the ascending, transverse, or descending part of the aorta widens abnormally. A dissecting aneurysm indicates a hemorrhagic separation in the aortic wall, usually within the medial layer. A saccular aneurysm describes an outpouching of the arterial wall, with a narrow neck. A fusiform aneurysm is a spindle shaped enlargement encompassing the entire aortic circumference. Thoracic aortic aneurysms are most common in men between ages 50 and 70. Some aneurysms progress to serious and eventually lethal complications. Cause: Usually this disorder occurs a s a consequence of atherosclerosis. Other possible causes include infection of the aortic arch and descending segments, congenital defects, trauma, and syphilis. Intimal tear in the ascending aorta as well as hypertension can initiate a dissecting aneurysm. Symptoms: Pain In a dissecting aneurysm, pain usually occurs suddenly, with a tearing or ripping sensation in the thorax or anterior chest. Pain may extend to the neck, shoulder, lower back, or abdomen but rarely reaches the jaw and arms. Temporary loss of consciousness (syncope) Pallor Sweating Shortness of breath Tachycardia Cyanosis Leg weakness Transient paralysis Effects of saccular or fusiform aneurysms varies according to the aneurysm's size and location and degree of compression, distortion, or erosion of surrounding structures.

The 59-year-old musician was treated Tuesday at a New York hospital and remains hospitalized. Neil Young, seen here at the U.S. Rock and Roll Hall of Fame ceremony in March, will not attend the Junos because of illness. (AP Photo) Doctors expect a full recovery, his publicist Bob Merlis told Associated Press. Young had been expected to perform Sunday at the Juno Awards in Winnipeg, the awards ceremony for the Canadian music industry. "I'm really disappointed that I won't be able to make it to Winnipeg for the Junos as I had hoped. I grew up there and was really looking forward to the show as well as spending some time with my old friends and family," Young said. "Thanks to my doctors, I'm feeling a lot better now so I hope I can get a rain check." Dr. Pierre Gobin, who performed the procedure on Young with another doctor, said the brain aneurysm was dangerous, but treated successfully with a "minimally invasive" neuroradiology procedure.

About Normal vessel wall for comparison with Aneurysm Click on Image to Enlarge it Normal vessel wall for comparison with Aneurysm High power view of normal artery wall showing slightly thickened intima, internal elastic lamina ( arrow) and well organized muscularis. Cerebral arteries have a thinner media and adventitia than arteries elsewhere in the body and no external elastic lamina. (Description By:Margaret Grunnet,M.D. ) (Image Contrib. by:Margaret Grunnet,M.D. UCHC ) Aneurysm Etiology The berry aneurysm is a small, saclike structure at the branchpoints of arteries with a wall which does not contain a media or internal elastic lamina and therefore can easily rupture during periods of hypertension or stress. Most commonly ruptures when the patient is 40-60 yrs. May also rupture intracerebrally. Pathogenesis Aneurysms are thought to be due to congenital absence of the media and internal elastic lamina with ballooning as the blood pulsates through the vessels over the years.

T99-46 Sharon Snider: 301-827-6242 September 28, 1999 Consumer Inquiries: 888-INFO-FDA FDA APPROVES TWO NEW DEVICES FOR ANEURYSM REPAIR FDA has approved two new devices for treating aortic aneurysms in the abdomen without major open abdominal surgery. Aortic aneurysms are weak bulging spots on the aorta, the largest blood vessel in the body. If an aneurysm enlarges and ruptures, it usually causes fatal internal bleeding. Currently, major open abdominal surgery is required to implant a graft and prevent the bulge from rupturing. The two new devices, called endovascular grafts, allow these aneurysms to be treated using minimally invasive procedures.
