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

Aneurysm is a weakness in a blood vessel in the brain that balloons and fills with blood. Aneurysm is a rare case to come across‚ that only fewer than 200‚000 US cases per year. Roughly about 13‚000 death occur each year in the US from aortic aneurysms. Most common sites aneurysm occurs is the brain‚ aorta‚ legs and spleen. Causes of aneurysm has no exact cause‚ certain factors has contributed to the condition. For example‚ damage tissues in the arteries‚ and arteries can be harmed by blockage

tear occurs. Boom! The balloon disintegrates. An aneurysm goes through a similar series of events‚ but with a more tramatic effect. Unfortunately‚ the cause of an aneurysm is not as simple as a single breath‚ but so complex that the root cause is to this point still hidden. Most of the information relating to aneurysms and their causes is focused on how pre-existing medical conditions and lifestyle choices exacerbate an aneurysm. In my eyes‚ aneurysms are an ever

just distal to the left subclavian artery. However‚ the constriction may be proximal to the left subclavian artery or rarely in the abdominal aorta. Aortic coarctation presenting during adult life‚ most frequently represents cases of recoarctation‚ following previous transcatheter or surgical therapy‚ or missed cases of native coarctation. Aortic coarctation may be recognized in the adult‚ usually because of systemic arterial hypertension and discrepant upper and lower extremity pulses. Patient

Aneurysms were first described by the 16th century anatomist and physician Vesalius‚ who believed they were simply a widening of the vessel (Collin et al 2009). An abdominal aneurysm (AAA) is a condition in which the abdominal aorta (a large blood vessel that supplies blood to the abdominal‚ pelvis and the lower limbs) becomes large and ballooning leading to the development of several symptoms. The condition more often occurs in males compared to females. It occurs more frequently in above the age

REVIEW OF LITERATURE Intracranial Aneurysm The normal functioning of brain requires continuous supply of oxygen and othernutrients. Brain which consists of more than 86.1± 8.1 billion neurons have a highmetabolic rate compared to other cells found elsewhere in the body(Azevedoet al.‚ 2009).The physiological demands for these cells are served by the densest vascularnetworks in the human body which receives 15% of cardiac output and 20% ofoxygen utilized by the body (Kumar et al.‚ 2003).

Over the years aneurysms have become more and more common than they used to be. An estimated of six million people go on in the world with an uncultured aneurysm. Every 8 out of 100‚000 people will have a ruptured aneurysm‚ and will most likely die from them. Aneurysms are small but very dangerous‚ and are more common in women than in men. They are also hereditary‚ and most people never even have a symptom when they have them until it is too late. It is also possible for the aneurysm to come back

Aortic Valve Stenosis Aortic Valve Stenosis is the narrowing or obstruction of the heart ’s aortic valve. The aorta is a large artery that originates in the left ventricle (lower chamber) of the heart. The narrowing and obstruction of the aortic valve prevents it from opening properly and blocks the flow of blood from the left ventricle to the aorta and onward towards the rest of the body. Aortic valve stenosis occurs in approximately 5 out of every 10‚000 people.1 It occurs more commonly

Aortic Dissection An aortic dissection is a tear in your aorta. The aorta is the main blood vessel that carries blood out of your heart to supply the rest of your body. It comes out of your heart and curves around‚ then goes down through your chest (thoracic aorta) and into your belly (abdominal aorta). The wall of the aorta has inner and outer layers. Aortic dissection occurs most often in the thoracic aorta. This is more likely to happen if the inner layer of the aorta has a weak spot or gets
