Brain Aneurysms What is a brain aneurysm? One could define a brain aneurysm as bulging, weak area in the wall of an artery that supplies blood to the brain. Over time, weak areas in the walls bulge out causing the blood vessel walls to become weaker as the aneurysm grows (Simon). In most human beings, a brain aneurysm can go undetected for years even possibly ones entire life. Some people however are not so lucky, in some instances, the aneurysm can rupture or explode, causing a hemorrhagic stroke
The cardiovascular system is the most important system in our body. This system is what keeps us alive. Beating on average 30 billion times a year, our heart is never able to stop and take a break. With every beat of our heart, the cardiovascular system moves blood, gases, nutrients, and hormones throughout the intricate vasculature of our bodies. An adult body contains over 60,000 miles of vessels, which can wrap around the world two and a half times. The vessel branching off of the heart is
Definition An AAA (abdominal aortic aneurysm) is defined as enlargement of at least 3 cm of the abdominal aorta. The majority of abdominal aortic aneurysms begins below the renal arteries and ends above the iliac arteries. The exact cause of (AAAs) is unknown. However, it is thought to be due to a degenerative process of the abdominal aorta caused by atherosclerosis. Artherosclerosis represents a response to vessel wall injury caused by inflammation, genetically regulated defects in collagen
An aneurysm is a disease of the arteries which due to a weak spot on a blood vessel, causes an outward bulging or ballooning of the arterial wall. It contributes to more than 25,000 deaths in the United States each year. The pathology of the disease is not well understood and even today there has yet to be a method of predicting a person’s probability of developing one such circumstance. Most un-ruptured aneurysms are incidentally discovered through CT scan or MRI and it has proven to be just as
The word aneurysm comes from the latin word aneurysma, which means dilation. An aneurysm is an abnormal local dilation in the wall of a blood vessel, usually an artery. It can be caused by a defect, a disease, or an injury. A cerebral aneurysm is an abnormal focal dilation of an artery located in the brain that results from a weakening of the inner muscular layer called the intima of a blood vessel wall (Brisman, 2014). The vessel develops a blister-like dilation that becomes thin and may rupture
Brain aneurysms practically go unnoticed and tend to have few to no symptoms until the rare occasion when the aneurysm ruptures. The bursting aneurysm causes bleeding in the brain and then often leads to a stroke. This is exactly what happened to my great-aunt Judy who survived a brain aneurysm and stroke. Brain aneurysms can also be referred to as cerebral aneurysms or intracranial aneurysms (IA). A brain aneurysm is formed when there is a bulging spot on the wall of an artery that supplies blood
diagnosis, treatment and follow-up of abdominal aortic aneurysms (AAA). It shall discuss the current AAA screening programme being implemented across the United Kingdom to include the use of Ultrasound and Computed Tomography (CT) as imaging modalities in the demonstration of AAAs. Both the advantages and disadvantages of the modalities used during the diagnosis and treatment of AAA will be shown. Irwin and Rippe (2007, p382) define an aneurysm as; “a segment of the aortic lumen whose diameter exceeds
It took me eighteen years to appreciate the profound impact my grandmother had on my life. She was the type of that always had her words of wisdom to pass on to her grandchildren, and the kind heart who donated her time to those who needed it. Being able to grow and learn with such a strong role model I became more like her each day. I started to use her words of wisdom in my daily life, and I remembered the importance of making time for those in need, both friends and strangers. My grandmothers
the post-surgical overall clinical outcome in 603 patients with an ACoA aneurysm. Of these patients, 367 (61%) had an excellent outcome, 107 (18%) had a good outcome, 99 (16%) had a fair/poor outcome, and 30 (5%) died. Of the 264 patients who presented in Hunt and Hess Grades 0–III, 86% had an excellent or good outcome. Fukushima et al.37 reported on the overall clinical outcome post-surgery in 138 patients with an ACoA aneurysm. In 119 cases (86%) the outcome was excellent or good, and 8 (6%) died
Brain Aneurysm Did you know that about 6% of the United States population may be living with an unruptured or a ruptured brain aneurysm? It’s shocking to know that 6% of population Maye be living with an aneurysm not knowing it. About 40 to 50 percent of the 6% have a ruptured brain aneurysm and will survive, but a shocking 20% of the 6% will live having no permanent damage from their ruptured aneurysm. A brain aneurysm is one of the most horrifying diseases. Specifically, a brain aneurysm is a
(Brain Aneurysm Foundation n.d.). In order to allow the blood to flow properly, the artery walls are composed of both a muscular and an elastic layer. Sometimes, a weak spot in the walls of these arteries occur due to disease, birth defects, or injury, particularly in areas where the arteries branch out. The thin spot of the artery wall gradually becomes weaker from the constant pressure of pumping blood, forming a cerebral aneurysm (Brain Aneurysm 2016). The most common form of aneurysm, a saccular
for ethical dilemmas. An ethical dilemma is___________. In Case Study 1, a woman needs a surgery to correct an abdominal aortic aneurysm. The risk of surviving the surgery is 50%, yet the woman is concerned about the potential scar which would result from the surgery and it negatively affecting her career as an erotic dancer. Timeliness is vital because if the aneurysm busts before the surgery can be performed, the patient will die. Despite impending death, the woman still refuses surgery. Her physicians
autonomy states that “you shall not treat a patient without the informed consent of the patient or his or her lawful surrogate, except in narrowly defined emergencies” (Health Care Ethics: Principles and Problems, 2009, p.32). An abdominal aortic aneurysm is a very high-risk diagnosis, but is non-emergent unless the aortic wall ruptures. It may seem that the patient is assuming very illogical and risky behavior, but it is still her right as a patient to deny the surgery if she so chooses. Unfortunately
either been through some of the best times of their lifes, filled with happiness and joy; or they have been through some of the worst times of their lifes, filled with anxiety and sorrow. The worst time in my life was when my brother had a brain aneurysm; I never had seen my family filled with so much fear before. My dad came into my room, turned on the light, and woke up my sister and I. I rose up out of my bed thinking that it was time to start getting ready for school. Then, my dad told
been a very important person throughout my life. My entire childhood was spent with her, but once I started getting older, it has been hard to keep up with each other. During this time of our distant relationship, she experience a ruptured brain aneurysm, and I have never gotten the opportunity to sit down with her and learn more about this. She cannot recall anything that happened after when she was experiencing symptoms up until four to five months post insult, so I also referred to my mom and
An ischemic stroke can occur in two ways. One of the ways in which ischemic stroke can happen is embolic stroke which occurs when a blood clot or plaque fragment forms somewhere in the body and travels to the brain. Once in the brain, the clot travels to the blood vessel small enough to block its passage. After that, the clots stay there and block the blood vessel which causes the stroke. About 15% of embolic strokes occur in people with atrial fibrillation (Ischemic stroke, 2016). In other words
Kawasaki disease was discovered by a Japanese pediatrician named Tomisaku Kawasaki. This disease is a “multisystem vasculitis that results in localized coronary artery elastin breakdown and aneurysm formation,” (Lau). This simply means it is a condition that causes inflammation of blood vessel walls in the body. Kawasaki disease is also referred to as “mucocutaneous lymph node syndrome,” by Black’s Medical Dictionary, (Marcovitch). It is most prevalent in infants and toddlers, “mainly in children
Cerbrovascular Accident ( CVA) It was a very exiting day of my live when I went to BODY World EXHIBIT, August 8,2013. As student studying anatomy and physiology it was very appropriate to realize that the human body Is amazing group of systems working together to maintain our homeostasis. I wanted to get the op- Opportunity to focus since is the first part of body. I learned a lot of information about that center. Our brain is generally programmed to the nerves cells branches that create connections
1) Which of the following is used to distinguish the diagnosis of MI (Myocardial Infarction) from that of Unstable angina? a) Serum levels of Cardiac Biomarkers (Troponin, CK-MB) b) Electrocardiograph (ECG) test c) The presence of S4 Heart sound d) Pain lasts for less than 5 minutes in an MI Rationale The correct answer is A because serum levels of cardiac biomarkers such as troponin and CK-MB are used for the final diagnosis of Myocardial infarction (STEMI, NSTEMI). Electrocardiograph (ECG) testing
means your heart has to work overtime and overall capacity of your cardiovascular system is lowered. When the LDL cholesterol embeds itself in the wall of the artery it than damages the artery then blood pressure expands it which causes an aneurysm. When an aneurysm is too weak there is a high possibility of it bursting, when that happens it leaves the cells in and around that area without oxygen. If that artery is connected to a major vital organ the person will most likely die. When the blood flow
