Vascular Services Abdominal Aortic Aneurysm Overview An abdominal aortic aneurysm (AAA) is a bulge in the aorta (the aorta is the main blood vessel coming from the heart that supplies blood to all organs) in your abdomen. In the case of an abdominal aortic aneurysm (AAA), an aneurysm develops in the part of the aorta that extends through the abdomen. The bulge occurs below the renal arteries (kidneys) and may extend into the iliac arteries (legs). Most AAAs occur in association with advanced atherosclerosis, an accumulation of fatty deposits on the vessel wall. Overview Stent-Graft Procedure Scripps Encinitas/La Jolla Program Scripps Clinic/Scripps Green Program Abdominal Aortic Stent-Graft Program The aneurysm may continue to grow larger until, like a balloon, it bursts ("ruptures"). The larger an aneurysm becomes, the easier it grows. Most people may not experience any symptoms of an AAA until it expands or bursts, resulting in massive bleeding. Aneurysm rupture can be a life-threatening event. The goal of all aneurysm operations is to prevent the aorta from rupturing. Traditionally, surgeons have repaired an AAA by replacing the affected portion of the aorta through a large abdominal incision. This “open” procedure requires general anesthesia, an average hospital stay of five to 12 days, and a prolonged recovery period of weeks or even months.

A brain Aneurysm, also called a cerebral or intracranial aneurysm , is a weak bulge in the blood vessel in the brain . The bulge is similar to a bulge in an inner tube or a thin balloon. There are also aneurysms that are not present in the brain. Aneurysms can occur in any blood vessel in the body. They tend to form where the artery divides or branches off. Brian aneurysms can and do grow. If they reach a certain size, usually over one inch, the aneurysm may begin to put pressure on the surrounding brain and cause progressive problems. These are called Giant aneurysms Aneurysms are very uncommon in patients below 20 years of age. They are most common in older patients. Aneurysms are rare in childhood and adolescence. What are the symptoms?

Abdominal aortic aneurysm may be caused by infection, congenital weakening of the connective tissue component of the artery wall, or rarely, from trauma. Abdominal aortic aneurysm can affect anyone, but it is most often seen in men 40 to 70 years old. A common complication is ruptured aortic aneurysm. This is a medical emergency where the aneurysm breaks open, resulting in profuse bleeding into the abdominal cavity. Ruptured aneurysm occurs more frequently in patients with larger (>5cm) aneurysms.

Weighing risks in abdominal aortic aneurysm Best repaired in an elective, not an emergency, procedure Yara Gorski, MD; John J. Ricotta, MD VOL 106 / NO 2 / AUGUST 1999 / POSTGRADUATE MEDICINE CME learning objectives To identify factors involved in the pathogenesis of abdominal aortic aneurysms To understand the relationship between aneurysm size and risk of rupture To recognize cardiovascular disease as the leading cause of death after abdominal aortic aneurysm repair Preview : Surgery is the only effective treatment for an abdominal aortic aneurysm. Unless serious contraindications prohibit it, repair should be undertaken in all patients with a known aneurysm while it is still an elective procedure. Complication and mortality rates increase dramatically when an aneurysm ruptures and surgery becomes an emergency procedure. In this article, the authors discuss what is known about formation and rupture of aneurysms, including patients at risk. In addition, they summarize diagnostic procedures and preoperative, operative, and nonoperative patient care. Gorski Y, Ricotta JJ.

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.

Further Reading What is a cerebral aneurysm? n intracranial aneurysm ("cerebral aneurysm," "brain aneurysm") is a protruding bubble or sac on a brain artery that balloons out over time. Aneurysms have thin, weak walls and have a tendency to rupture causing hemorrhage into and around vital brain structures. How common are aneurysms? The actual incidence is difficult to estimate since not all aneurysms present to medical attention. Autopsy studies indicate a prevalence in the general population of approximately 5%. Only a fraction those aneurysms rupture. What causes aneurysms to form? The etiology of aneurysm formation is debated but is thought to be due to a small area of weakness in the blood vessel wall near a branch point of the blood vessel. A number of factors may contribute to aneurysm formation. These include: congenital predisposition arterial hypertensive disease cigarette smoking complications of blood infections traumatic injury How do patients with aneurysms present to the doctor?

//var DOCUMENTGROUP=''; //var DOCUMENTNAME=''; //var ACTION=''; Heart Information Center Aneurysms (En español) Most people think that an aneurysm means bleeding in the tiny blood vessels of the brain. Actually, aneurysms are a balloon-like bulge in a blood vessel, and they can also affect the larger vessels in your body. (These larger vessels are called arteries.) An aneurysm happens when the pressure of blood passing through part of a weakened blood vessel forces the vessel to bulge outward, forming what you might think of as a thin-skinned blister. Not all aneurysms are life-threatening. But if the bulging stretches the artery too far, this vessel may burst, causing a person to bleed to death. An aneurysm that bleeds into the brain can lead to stroke or death. Where do aneurysms happen in the body? In the arteries that supply blood to the brain. This is called a cerebral aneurysm. In parts of the aorta. The aorta is the large vessel that carries blood from the heart to other parts of the body. Aortic aneurysms can happen in the area below the stomach (abdominal aneurysm) or in the chest (thoracic aneurysm). An abdominal aortic aneurysm (AAA) is usually located below the kidneys.

77. Aneurysm (Aneurism: Aortic, Abdominal And Brain) aneurysm (aneurism) is a bulging out of part of the wall of a blood vessel. An aneurysmforms where the wall has weakened, often due to the buildup of plaque. http://www.heartcenteronline.com/The_Aneurysm_Center.html

The Aneurysm Center Aneurysm (aneurism) is a bulging out of part of the wall of a blood vessel. There are a number of different types of aneurysms including an abdominal aortic aneurysm and a cerebral or brain aneurysm. An aneurysm forms where the wall has weakened, often due to the build-up of plaque. It may also be an inherited condition or a complication of high blood pressure (hypertension). Left untreated, aneurysms may tear or burst (a ruptured aneurysm). An aortic aneurysm is also known as an abdominal aneurysm, thoracic aortic aneurysm or abdominal aortic aneurysm. This condition is characterized by the ballooning out, of part of the wall of the aorta, the main artery carrying oxygen-rich blood from the heart to the rest of the body. If accompanied by an aortic dissection , it is classified as a dissecting aortic aneurism. A condition called polyarteritis nodosa has been associated with abdominal aortic aneurism. Cerebral aneurysms (brain aneurysms or berry aneurysms) are the bulge in the wall of a blood vessel in the brain (one of the cerebral arteries). A cerebral aneurism (brain aneurism) is typically found where the arteries branch at the base of the brain. The cause is unknown, but smoking increases a person's risk of developing this condition, which can lead to a stroke or transient ischemic attack Ventricular aneurysms (ventricular aneurisms) are the bulging or ballooning out of part of the wall of one of the heart's lower chambers (ventricles), usually the left. They also known as a ventricular septal aneurisms, interventricular aneurisms or simply a septal aneurisms.
