Cerebral Aneurysm • 10 out of every 100,000 people get it • 30,000 people per year in the U.S. alone • causes damage to brain tissue is blood spills/kills cells which impacts everyday life and brain/body function • anyone, at any age • more common among adults than children -more common in women than men • common between adults ages 30-60 Causes: Who does it Affect? Treatment Video: • also known as an intracranial or intracerebrum aneurysm • weak or thin spot on blood vessel in the brain (located on the vessels) • balloons/inflates out and fills with blood • can put pressure on a nerve or surrounding brain tissue • birth defects/abnormalities in artery wall • common among connective tissue disorders, polycystic kidney disease, and some circulatory disorders • trauma, injury to the head, high blood pressure, infection, tumors, atherosclerosis, smoking, and drug abuse • after treatment, possibility of paralysis • slow recovery • not able to do previous activity • depends on type, size, and location (along with patient's health status -age, health, etc.) • two treatment options possible 1) Microvascular Clipping- cutting of the flow of blood to the aneurysm 2) Endovascular Embolization- where using a catheter, a coil is wrapped around the aneurysm causing it to have a blood clot and cut blood circulation (may be done more than once) Prognosis By: Ophelia Aoraha
Transcript: By: Nick Barry & Daniel Pageau Other Risks Risks & Benefits M.R.A. could damage blood vessels because it passes through them so, in the heart it is possible to provoke a stroke or heart attack which can lead to death pregnant women should inquire about the risks to their unborn baby Unruptured-Symptoms of an unruptured aneurysm include pain above and behind the eye, dilated pupil, change in vision double vision, numbness, weakness or paralysis on one side of the face, and/or a drooping eyelid. If you experience any of these symptoms you should contact your healthcare professional. A cerebral aneurysm specifically affects the tissue of the brain and tissues of the arteries inside the brain. Due to the fact that the aneurysm is leaking blood inside your brain it causes irritation and pressure inside the skull. This pressure restricts blood flow and causes damage to structures inside the brain. "What Are the Risks of MRI Scans?" Risks of an MRI or MRA Scan? © 2009-2011 P. Griffith Creative, LLC., n.d. Web. 10 Nov. 2013. <http://www.two-views.com/MRI/Risks.html>. References Benefits - eliminate the need for surgery present a very detailed, clear and accurate picture of the blood vessels makes it possible to assess vessels in several specific areas Benefits - The test is not painful and you cannot feel it the procedure can be repeated without problems Because radiation is not used Diagnostic Tests The effects on quality of life due to a ruptured aneurysm are extensive. 30 to 40 percent of ruptures result in death, 25 to 35 percent result in moderate to severe brain damage, and 15 to 30 percent experience only mild difficulties or almost none. The brain damage received from the bleeding aneurysm can leave you with extreme mental and physical deficits, such as loss of vision, paralysis or numbness in a limb, trouble speaking or understanding a language, and seizures. Angiography - a dye test used to analyze the arteries or veins If you have problems with your kidneys, you could develop a severe reaction This reaction can affect tissues throughout the body, e.x. (skin, joints, liver and lungs.) If you have a history of kidney disease M.R.I. and M.R.A. are not suggested M.R.A. Ruptured-Symptoms of a ruptured aneurysm include sudden extremely severe headache, nausea and vomiting, stiff neck, blurred or double vision, sensitivity to light, seizure, a drooping eyelid, loss of consciousness, and/or confusion. Specialized cells Risks - anxiety and claustrophobia can be felt when entering the scanner kidneys could develop a severe reaction after receiving the MRI contrast dye that is used to make blood vessels more visible M.R.A. (magnetic resonance angiography) - produces detailed images of blood vessels (painless and noninvasive,) can show size and shape of an unruptured aneurysm Cerebral Aneurysm Risks & Benefits Angioraphy - Risks - there is a risk to a fetus in the first 12 weeks of a woman’s pregnancy the magnet used may affect pacemakers, artificial limbs, and other medical devices that contain iron foreign metal materials could distort the M.R.A.'s images Angiography "Benefits and Risks of Coronary Angiogram Procedure?"

Causes Connectivity tissue disorder Polytheistic kidney disease Circulatory disorders high blood pressure Atherosclerosis Vascular system disease Cigarette or drug abuse. such as cocaine Brain trauma (mostly caused by accidents) Mycotic Aneurysms ( infection of artery wall) Symptoms Pain behind and above eye Numbness Vision changes (vision may become weaker) Weakness Sensitivity to light Paralysis on one side of the face Dilated Pupil Symptoms Hemorrhage: Free flow of blood from a ruptured aneurysm Symptoms of Hemorrhage Severe headaches Nausea Loss of consciousness Double vision Vomiting Stiff neck Affect on life after treatment Lasting Effect When the doctor detects an aneurysm, you are sent for tests for more details. During the surgery the doctors cut off the aneurysm before it ruptures and leads to brain damage or any other brain problems. If it has already ruptured then going through surgery will only stop the blood from causing anymore damage to the brain, not reverse the damage that has already been done. There may or not be symptoms after the surgery. Diagnostics What diagnostics are needed? Computed Tomography (CT) Magnetic Resonance Imaging (MRI) Cerebra-spinal Fluid Test Computed Tomography (CT) CT This test helps confirm what problems you have within your brain and blood vessels. Provides a more detailed information of the problem detected by an MRI or CT scan. May have allergic reaction to the contrast dye May have blood clot or bleeding where the needle was taken out, which can block blood flow to the leg The catheter may damage an artery or a artery wall, which can result in blockage of blood flow and cause a stroke (rare) What are the benefits? * CT scans can provide a detailed information to diagnose,plan treatment for,and evaluate many conditions in adults and children What are the risks? *From expose to ionize radiation and possible reactions to the intravenous contrast agent,or dye,which may be used to improve visualization can cause life time risks of developing cancer Magnetic resonance imaging (mri) Uses magnetic radio waves to create images that are viewed on the computer The patient lies down on a long table that slides into the magnetic resonance scanner that looks like a tube Radio waves about 10,000 to 30,000 times stronger are then sent through your body The images are then taken because of the magnetic force once the force is turned off the Protons are then returning back to their positions as this happens they send radio waves that the scanner picks up and forms a picture. MRI What are the risks? Allergic reactions What are the benefits? Can detect variety of conditions of the brain such as cysts, tumors, bleeding, swelling, developmental and structural abnormalities, infections, inflammatory conditions,or problems with blood vessels. detect damage to brain cause by injury or stroke detect chronic disease of nervous system provides a clear image from parts of the brain Cerebrospinal fluid test If you have had a hemorrhage , there will most likely be red blood cells in your fluid surrounding your brain and spine. that is called Cerebrospinal Fluid Doctor will recommend a cerebrospinal fluid test if you have symptoms of a ruptured aneurysm, but a CT scan has not shown evidence of bleeding CFT What are the benefits? bacterial or viral meningitis fungal infections bleeding around the brain (subarachnoid hemorrhage) brain and spinal cord damage epilepsy multiple sclerosis Lyme disease Guillain-Barré syndrome What are the Risks? discomfort or pain during the procedure bleeding into the spinal cord headache as a result of CSF leakage infection nerve damage Works Cited Citations Durani, Yamini.

Transcript: Aneurysm may burst and bleed into the brain, causing serious complications, including hemorrhagic stroke, permanent brain damage, or death Presentation Cerebral Aneurysms Surgical clipping. This surgery involves placing a small metal clip around the base of the aneurysm to isolate it from normal blood circulation. This decreases the pressure on the aneurysm and prevents it from rupturing. Embolization a small tube is inserted into the affected artery and positioned near the aneurysm. These procedures are less invasive and are believed to be safer than surgical clipping. But they may not work as well at reducing the risk of a later rupture. How is the condition treated? Who does it affect? -Most aneurysms cause no symptoms and may only be discovered during tests. Unruptured aneurysm will cause problems by pressing on areas of the brain, symptoms may include severe headaches, blurred vision, changes in speech, and neck pain. Presentation -About 10% of patients with a ruptured aneurysm die before receiving medical care. -If untreated, 50% will die within a month -25% of patients sustaining another bleeding episode within a week Etiology -Brain aneurysms develop as a result of thinning, degenerating artery walls -a person may inherit the tendency to form aneurysms, or aneurysms may develop due to hardening of the arteries, and aging. Symptoms for a ruptured aneurysm include a sudden, severe headache, neck pain, nausea, vomiting, sensitivity to light, fainting, and seizures -women are more likely to develop aneurysms -African Americans are more likely than whites to develop an aneurysm -risk is higher in people who have a history of high blood pressure -smoking can greatly increase chances of brain aneurysm rupturing. Dangers? Survival Rate?
Transcript: CEREBRAL ANEURYSM Cause Cerebral aneurysm can be congenital, meaning it is an inborn abnormalety in anartery wall. connective tissue disorders polycystic kidney disease circulatory problems anteriocenous malformations Symptoms Most patients dont show symptoms until they are very large or have bursted. Pain above and behind eye numbness weakness patalysis on one side of face dialated pupils vision change Not all anuerysm burst. Some people with small may be monitored to detect any growths. At some points they can be removed surgically. One of them is Microvascular clipping. The other one is Endovascular embolization. And that's all folks :p I'm done ;D This is common in people with certain genetic diseases. Bleeding in the space between the skull and brain. Fluid dialates pathwys called ventricles. This can swell and press against the brains tissue. Can compress cranial nerves. Can cuase loss of control in a specific part of the brain then can cause loss of speach or muscle movements. What cerebral aneurysm? Izzy Suarez Change in structure and function In memory of Mandy ;D Treatment This is the dialation, building, or ballooing-out of part of the wall of an artery, in the BRAIN! This can occure at any age. It also is more common in women than in men.
Transcript: Cerebral Aneurysm Cerebral aneurysm is when the wall of a brain blood vessel weakens and causing blood to buldge or balloon out of the blood vessel Cerebral Aneurysm only occurs in the brain or in any blood vessel that supplies the brain An anuerysm is no bigger than a few millimetersto a centimeter The maximum size of an aneurysm is 2 centimeters Cerebral Aneurysm is usually common with in women Atheroscierosis [ hardering of arteries] What are the Symptoms of Cerebral Aneurysm? Double vision Loss of vision Severe head aches Eye and neck pain Stiff neck Confusion Eyelid droopling Muscle weakness Numbness Seizers Speech imparliment [ when normal speech is distrupted] What tests do docters use to determine whether a person is diagnosed with Cerebral Aneurysm? •Cerebral angiography or spiral CT scan angiography of the head to reveal the location and size of the aneurysm •Cerebrospinal fluid exam (spinal tap) •CT scan of the head •Electroencephalogram (EEG) •MRI of the head What surgeries are preformed to treat a Cerebral Aneurysm? Coiling Method Coiling is when docters enter a small plastic tube through an artery in the paitnet's leg until it reaches the aneurysm. The tube curls into a tiny ball and blocks the blood from flowing Clipping method Clipping is when docters takes a surgical clip to clip the blood vessel and prevent the aneursym from getting bigger.

Transcript: Cerebral WHEn HOW Jocelyn Philip Diagnostic Studies WHY Aneurysm What is cerebral aneursym? intracranial or intracerebral aneurym weak or thin spot on a blood vessel that balloons out and fills with blood. This can put pressure on a nerve or surrounding brain tissue. The weakness can cause a leak or rupture causing a hemorrhage in the surrounding tissue. intracranial or intracerebral aneurym Types of cerebral aneurysms Types of cerebral aneurysms Clinical Manifestations Most intracranial aneurysm are asymptomatic unless ruptured, and so they can usually be found either incidentally or when patient presents with subarachnoid hemorrhage. Symptomatic patients: Headache (worse headache of all time) Loss of visual acuity Cranial neuropathies (i.e CN 3 palsy) Facial pain, Ischemia due to emboli originating within the aneurysm Clinical Manifestations WHAT WHAT ARE THE dIAGNOSTIC TESTS?

Hemostasis is obtained by injecting a thrombogenic substance (eg, powdered gelatin) or metallic coils into the bleeding vessel. Indications for angiographic embolization include: Aneurysm Arteriovenous fistula Solid organ injury (particularly of the liver) or pelvic fracture with bleeding severe enough to require postresuscitation transfusion Coiling Embolization or Endovascular Coiling Goal of surgical clipping: isolate an aneurysm from the normal circulation without blocking off any small perforating arteries nearby. Under general anesthesia, an opening is made in the skull, called a craniotomy. The brain is gently retracted to locate the aneurysm. A small clip is placed across the base, or neck, of the aneurysm to block the normal blood flow from entering. The clip works like a tiny coil-spring clothespin, in which the blades of the clip remain tightly closed until pressure is applied to open the blades. Clips are made of titanium and remain on the artery permanently Surgical Clipping IDEAS REFERENCES rEFERENCES rEFERENCES: 1.https://www.uptodate.com/contents/unruptured-intracranial-aneurysms?source=search_result&search=cerebral%20aneurysm&selectedTitle=1~144#H1 2. http://neuroangio.org/neuroangio-topics/introductory-brain-angiography/ 3. https://www.merckmanuals.com/professional/injuries-poisoning/abdominal-trauma/overview-of-abdominal-trauma#v6623807 4. http://emedicine.medscape.com/article/337027-overview#a3 - Joyce Meyer "You cannot have a positive life and a negative mind."
