Aneurysm

on any of those medications that they're not familiar with. to talk about a arterial aneurysms or aneurysms. We’re going to look at the aneurysms of central arteries, an aneurysm is an outpouching or dilation of the arterial wall and it is a common problem that involves the aorta. over time the dilated aortic wall

To begin with, the word aneurysm derives from the Latin word “aneurysma.” In Latin “aneurysma” means dilation and dilation means that act of expanding. From this, it is easier to figure out what an aneurysm really is. The definition of the English word aneurysm means, blood-filled dilation of a blood vessel. There are several different types of aneurysm, but this report will only cover a cerebral one. Intracranial aneurysms are classified as dissecting, saccular, and fusiform. There are many causes

Ruptured Saccular Intracranial Aneurysm associated with Arteriovenous Malformation Introduction An arteriovenous malformation (AVM) is an abnormal collection of blood vessels in which arterial blood flows directly into the draining vein without the normal interposed capillaries. AVM are tangled anastomosis of blood vessels of varying calibre in which arteriovenous shunting occurs in a central nidus in which the area towards in which multiple feeding arteries converge and from which enlarged vein

Introduction Despite considerable advances in surgical treatment, the ruptured human abdominal aortic aneurysm (AAA) is still associated with a mortality rate of 65–85% [1, 2] . A diameter is currently the only reliable determinant of the imminent rupture of an AAA and patients exceeding 5.5 cm generally undergo surgical or endovascular intervention [2, 3] . However, the outcome of rupture is poor with less than half of the patients being delivered to the hospital alive [1, 4] . It is well known

the most needed skill for a surgeon, a brain surgeon to be exact. Focusing on the central nervous system I can fix the abnormalities and diseases of the brain. One of the highest pressure surgeries neurosurgeons perform are the clipping of aneurysms. Aneurysms are a ballooning and weak area in the wall of an artery that supplies blood to the brain. They can burst at any moment and cause a subarachnoid hemorrhage, which is bleeding under the layer of brain coverings called the arachnoid. This can

for providing oxygen to the entire body. An aortic aneurysm occurs when an artery wall of the aorta weakens. The weakening then causes the wall of the aorta to expand and bulge out (United States National Library of Medicine, 2014). Dilation of at least one and a half times the normal diameter of the aorta is qualification for an aneurysm (Novaro, 2014). Nearly 50,000 deaths in the United States annually can be attributed to a thoracic aortic aneurysm (McLarty, A. J., Bishawi, M., Yelika, S. B., Shroyer

Mycotic aneurysm is a focal dilation of an infected arterial wall. This uncommon disease follows an aggressive and unpredictable clinical course with significant mortality, and presents unique diagnostic and therapeutic challenges. This review discusses the pathogenesis, diagnosis, and therapeutic management of mycotic aneurysms. Historical Perspective Virchow first described a saccular outpoutching along an arterial wall corresponding to an embolic source in 1847 [1]. Mycotic aneurysms were initially

less common aneurysm would be the thoracic aortic aneurysm, which is affected on the part of the aorta that is running through the chest. Studies show that Thoracic aortic aneurysm has an annual survival rate of 50 percent without treatment and 85 percent when it is done with surgery. The next type of aneurysm is known as a cerebral aneurysm, which is an aneurysm of the arteries that supply blood to the brain with blood known as intracranial aneurysms. When a brain has a ruptured aneurysm it can be

will discuss how an abdominal aortic aneurysm occurs, who are at risk of developing one, how the body responds as well as the clinical presentations of the signs and symptoms. It will also give an explanation of how the clinical presentations relates to the pathogenesis of abdominal aortic aneurysms as well as how it affects homeostatic mechanisms. Before those subjects it is necessary to understand what an abdominal aortic aneurysm is. An abdominal aortic aneurysm is an augmented area of the lower

Abdominal Aortic Aneurysms The abdominal aorta supplies oxygenated blood to the abdomen, pelvis and legs. An abdominal aortic aneurysm arises when a weakened area of the arterial wall within the abdomen becomes very large and begins to distend outward; therefore, creating an increased susceptibility to rupture under high pressure (Eagleton, 2012). The majority or abdominal aortic aneurysms are located inferior to the kidneys and in order to be considered an abdominal aortic aneurysm, the local dilation
