Transcript: Death toll exceeds prostate cancer and approaches breast cancer More people die from bursting aortas than from AIDS and brain cancer combined. An aneurysm can occur in any part of the body. They tend to most commonly occur on the wall of the aorta - the large trunk artery that carries blood from the left ventricle of the heart to branch arteries. The aorta goes down through the chest and into the abdomen, where it divides into the iliac arteries (two branches). There are two main types of aneurysms: A throbbing sensation in the abdomen Back pain Abdominal pain - this pain frequently spreads towards the back If the aneurysm continues to grow and presses on the spine or chest organs the patient may experience: Coughing Loss of voice Breathing difficulties Problems swallowing NEUROLOGICAL FUNCTION LOSS ANEURYSM HISTORY Albert Einstein was operated on by Rudolf Nissen with use of this technique in 1949, and survived five years after the operation. Endovascular aneurysm repair was first performed in the late 1980s and has been widely adopted in the subsequent decades. ANEURYSM? FUN FACT LONG TERM EFFECTS . Even though the majority of aneurysms never burst, when they do, the survival rate is only 10%. Most people never reach the hospital alive. On the other hand when a large aortic aneurysm is detected and operated on, the survival rate exceeds 95%. The first historical records about aneurysms are from Ancient Rome in the 2nd century AD, when Greek surgeon Antyllus tried to treat the aneurysm with proximal and distal ligature, central incision and removal of thrombotic material from the aneurysm. However, attempts to treat the aneurysms surgically were unsuccessful until 1923. In that year, Rudolph Matas (who also proposed the concept of endoaneurysmorrhaphy), performed the first successful aortic ligation on a human. Other methods that were successful in treating the aneurysm included wrapping the aorta with polyethene cellophane, which induced fibrosis and restricted the growth of the aneurysm. SURVIVAL RATE SYMPTOMS this is when bleeding occurs in the subarachnoid space---between the brain and the surrounding tissue Aortic aneurysm - occurs in the aorta. Can be abdominal, or thoracic (higher up). Cerebral aneurysm - occurs in an artery in the brain. An aneurysm occurs when part of a blood vessel (artery) or cardiac chamber swells, - either the blood vessel is damaged or there is a weakness in the wall of the blood vessel. As blood pressure builds up it balloons out at its weakest point. The swelling can be quite small or very large - when large it tends to extend along the blood vessel. As the aneurysm grows there is a greater risk of rupture - this can lead to severe hemorrhage, and other complications, including sudden death.

Transcript: An aneurysm is an abnormal widening or ballooning of a part of an artery because of weakness in the wall of the blood vessel. •The major artery from the heart (the aorta) •The brain (cerebral aneurysm) •In the leg behind the knee (popliteal artery aneurysm) •Intestine (mesenteric artery aneurysm) •An artery in the spleen (splenic artery aneurysm) <div style='position: relative; float: left; text-align: center;'><a href=''><img alt='Abdominal Aneurysm' src=''/><br/>Abdominal Aneurysm</a></div> Surgery is normally recommended. The type of surgery and the urgency of surgery depends on your symptoms and the size and type of aneurysm. Some patients may need endovascular stent repair. A stent is a tiny tube used to prop open a vessel or reinforce it's wall. . This procedure can be done without a major cut, so you recover quickly. However, not all patients with aneurysms are candidates for stenting. It is not known exactly what causes aneurysms. Some aneurysms are present at birth (congenital). Defects in some of the parts of the artery wall may be responsible. Your health care provider will perform a physical exam if you are experiencing symptoms similar to that of aneurysms. Tests used to diagnose an aneurysm are a CT Scan and an Ultrasound. PREVENTION: WHAT IT IS: SYMPTOMS: ANEURYSM COMPLICATIONS: TREATMENT: CAUSES: LOCATIONS: COMMON TESTING: Control of high blood pressure may help prevent some aneurysms. Following a healthy diet, getting regular exercise, and keeping your cholesterol at a healthy level may also help prevent aneurysms and their complications. Smokers are at a higher risk than most for getting aneurysms. The main complications of aneurysm are: •Compression of nearby structures such as nerves. This may lead to weakness and numbness. (most common with aneurysms that occur in the artery behind the knee) •Infection, which can lead to body-wide illness and rupture •Rupture, which causes massive bleeding that could lead to death. Massive bleeding is commonly seen with abdominal aortic aneurysms, mesenteric artery aneurysms, and splenic artery aneurysms. Rupture of brain aneurysms can cause stroke, disability, and death. The symptoms depend on the region of the aneurysm. If the aneurysm occurs close to the body's surface, pain and swelling with a throbbing mass is often seen. Aneurysms within the body or brain often show no symptoms. If an aneurysm ruptures, then pain, low blood pressure, a rapid heart rate, and lightheadedness may occur. The risk of death after a rupture is high. High blood pressure, high cholesterol, and cigarette smoking may increase your risk of certain types of aneurysms. High blood pressure is thought to play a role in abdominal aortic aneurysms. Atherosclerotic disease (cholesterol buildup in arteries) may also lead to the formation of some aneurysms. Pregnancy is often linked to the formation and rupture of splenic artery aneurysms.


Transcript: Red blood cells (Erythrocytes, RBC) White blood cells (Leukocytes, WBC) Plasma Platelets The blood moves through the heart to the pulmonary pathways by diastole and systole as well as the skeletal muscles of the body. Diastole is when the blood is when the ventricles or atria relax and fill with blood. Systole is when the ventricles and atria contract, ejecting blood and closing valves preventing back flow. Heart When an aortic aneurysm happens the heart is trying to push blood towards the body and filter the blood but the artery has burst and can not transport blood, ultimately internally bleeding out. Movements Movement Erythrosytes contain hemoglobin and transport oxygen from the lungs to the body cells, they make up around 44% of the blood. Leukosytes are there to protect the body from disease and fight the body of viruses, they make up around 1% of the body's blood.

Aimee & Jessica RBC & WBC Platelets are the clotting portion of blood. Platelets are broke open by rough surfaces causing them to convert firbinogen to firbin, then forming a net to catch RBCs and causing them to clot, the oxygen starts the clotting. Platelets make up around 1% of blood. Plasma is what holds everything together in the blood, holding the RBCs, WBCs, and as well as platelets. Plasma makes up around 55% of blood. Aneurysm Blood


Transcript: What happens when you get an aneurysm treatment? A brain aneurysm happens when one of your arteries hardens. the symptoms a sudden severe headache that is different from past headaches,neck pain,nausea and vomiting ,sensitivity to light fainting or loss of consciousness, seizures, numbness or weakness of one side of the face,a dilated pupil, and change in vision. The things that cause aneurysms are smoking,drug abuse,high blood pressure,and trauma. The people who are likely to get an aneurysms are people who have had a brain aneurysm are most likely to get another one,women are more likely to develop a brain aneurysm,african Americans are more likely,and people who smoke. What are treatments for an aneurysm? Aneurysm You will risk damaging the blood vessel,causing lots of bleeding damaging nearby brain tissue, and causing the surrounding blood vessels to go into spasm also in the process depriving the brain tissue of blood supply and causing you to get a stroke. By:Imari Brown Science 7H 2/28/13 What cause aneurysm? Who are likely to get one? What is an aneurysm? There are two treatments for an aneurysm.The treatments are called Clipping and Coiling.Clipping is one of the treatments for an aneurysm. Clipping is a neurosurgeon can operate on the brain by cutting open the skull and identifying the damaged blood vessel, then putting a clip across the aneurysm. Coiling is a neurosurgeon or interventional radiologist can thread and a tube through the arteries with an angiogram then identify the aneurysm and fill it with coils of platinum wire or with latex.
