Aneurysm meaning

Aneurysms can happen to anyone at any age, and most of the time, they have no symptoms or warning signs. Most people would agree that’s a scary possibility. But the fact is knowing the causes of aneurysms can help you prevent them and get prompt treatment should one affect you in the future. “An aneurysm is some sort of bulging of a blood vessel within the body,” says Arteries are a type of blood vessel that carry oxygen-rich blood from the heart to other parts of the body. The thick walls of the arteries are meant to hold up under normal blood pressure, but when the walls weaken or become damaged, an aneurysm can develop. Aneurysms have two shapes: ( Saccular Aneurysm The most common type, this is also known as the “berry” aneurysm because of the berry-like sac that develops on the “y” section of the artery, as well as the neck and stem that forms. Fusiform Aneurysm This type of aneurysm is less common and has an equal “outpouching” of the artery wall on all sides without a stem. It’s also the type of aneurysm that has a lower risk of rupture. Your doctor may recommend surgery for an aneurysm that has ruptured or is at risk of rupturing. While you might be uneasy about the thought of surgery, the survival rate of surgery is far greater than leaving a potentially fatal aneurysm in your body. For example, there’s an estimated 90 percent survival rate for aortic (heart) aneurysm surgery. Many aneurysms can go undetected for years because they don’t cause noticeable symptoms....

What is endovascular coiling? Healthcare providers use endovascular coiling, also called endovascular embolization, to block blood flow into an aneurysm. An aneurysm is a weakened area in the wall of an artery. If an aneurysm ruptures, it can cause life-threatening bleeding and brain damage. Preventing blood flow into an aneurysm helps to keep it from rupturing. For endovascular coiling, healthcare providers use a catheter, a long, thin tube inserted into a groin artery. The catheter is advanced into the affected brain artery where the coil is deployed. X-rays help guide the catheter into the artery. The coils are made of soft platinum metal, and are shaped like a spring. These coils are very small and thin, ranging in size from about twice the width of a human hair to less than one hair's width. Healthcare providers also use coiling to treat a condition called arteriovenous malformation, or AVM. An AVM is an abnormal connection between an artery and a vein. It may happen in the brain, spinal cord, or elsewhere in the body. Why might I need endovascular coiling? Healthcare providers most commonly use coiling to treat a cerebral aneurysm at risk for rupturing. In some cases, they may use it to repair a ruptured aneurysm. There may be other reasons for your healthcare provider to recommend a coiling procedure. What are the risks of endovascular coiling? If you are pregnant or think you may be pregnant, you should tell your healthcare provider. There is a risk for allergic re...

What Is a Brain Aneurysm? A That area of the blood vessel gets worn out from constant flow of Saccular aneurysms are the most common type of brain aneurysm. They bulge out in a dome shape. They’re connected to the artery by a narrow “neck.” Fusiform aneurysms aren’t as common as saccular aneurysms. They don’t pouch out in a dome shape. Instead, they make a widened spot in the blood vessel. Although brain aneurysms sound alarming, most don’t cause symptoms or health problems. You can enjoy a long life without ever realizing that you have one. But in rare cases, aneurysms can grow big, leak, or explode. Brain Aneurysm Symptoms The type of symptoms you have from a brain aneurysm depend on whether it ruptures or not. Ruptured brain aneurysm symptoms You need emergency care if you suddenly get an intensely painful headache, lose consciousness, or have any of these other symptoms of an aneurysm rupture: • Intense • Loss of consciousness • • Drowsiness • Loss of balance in things like walking and normal coordination • • Dilated pupils • Sensitivity to light • Sudden blurred or • Drooping eyelid • Confusion or trouble with mental awareness • Although brain aneurysms usually don’t show symptoms, they can press on the brain and nerves as they get bigger. Unruptured brain aneurysm symptoms See a doctor at once if you’re having a new headache or pain above or behind your eye. Call 911. Other symptoms of an unruptured aneurysm are: • Dilated pupils • Blurred or double vision • Drooping...

Detecting an Your best strategy is to: • Know if you are at risk • Be familiar with the symptoms of an aneurysm • Take preventive steps Although most aneurysms have no symptoms, you may see: • Sudden and severe • An unusual pulsing sensation, pain, or a lump anywhere Some symptoms can be a sign of a specific type of aneurysm: • Pain in the • A pain in the chest, hoarseness, persistent • A throbbing sensation or lump directly behind the • A severe When to Call Your Doctor If you think you may have an aneurysm, make the call right away. Many are serious and require a medical evaluation. An aneurysm that ruptures could be life-threatening.

An aneurysm is a bulge in the wall of an artery. Aneurysms form when there’s a weak area in the artery wall. Untreated aneurysms can burst open, leading to internal bleeding. They can also cause blood clots that block the flow of blood in your artery. Depending on the location of the aneurysm, a rupture or clot can be life-threatening. Overview What is an aneurysm? An aneurysm is a weak or expanded part of an artery, like a bulge in a balloon. Your arteries are large Aneurysms usually aren’t painful. You might not know you have one unless it ruptures or bursts. If it does, it can be very dangerous or even fatal. What are the different types of aneurysms? An aneurysm can form in any of the arteries in your body. Aneurysms can occur in your Types of aneurysms include: • Abdominal aortic aneurysm (AAA): • Cerebral aneurysms: Also called brain aneurysms, these aneurysms affect an artery in your brain. A saccular (or berry) aneurysm is the most common type of cerebral aneurysm. It forms as a sac of blood attached to an artery. It looks like a round berry attached to the artery. • Thoracic aortic aneurysm: These aneurysms are less common than AAAs. • Carotid aneurysm: • Popliteal aneurysm: These develop in the artery that runs behind your knees. • Mesenteric artery aneurysm: This type of aneurysm forms in the artery that brings blood to your intestine. • Splenic artery aneurysm: These aneurysms develop in an artery in your spleen. How common are aneurysms? Unruptured brain aneur...

Abdominal aortic aneurysm An abdominal aortic aneurysm (AAA) occurs when the large blood vessel (the aorta) that supplies blood to the abdomen, pelvis and legs becomes weakened, enlarged or balloons outward. This type of aneurysm occurs most often in older men who have at least one or more risk factor, including emphysema, family history, The rupture of an abdominal aortic aneurysm is a medical emergency, and only about 20% of patients survive. Call 911 and seek immediate medical attention if you or someone you know has extreme pain in the belly or back that doesn't go away. Cerebral aneurysm Cerebral aneurysms, which affect about 3-5% of the U.S. population, occur when the wall of ablood vessel in the brain becomes weakened and bulges or balloons out. The three types of cerebral aneurysms are: berry (saccular), fusiform and mycotic. The most common, "berry aneurysm," occurs more often in adults. It can range in size from a few millimeters to more than two centimeters. A family history of aneurysms may increase your risk. Conditions that injure or weaken the walls of the blood vessel, including atherosclerosis, trauma or infection, may also cause cerebral aneurysms. Other risk factors include polycystic kidney disease, narrowing of the aorta and Like other types of aneurysms, cerebral aneurysms may not have any symptoms. But symptoms may include: • Severe headache • Pain above and behind the eye • Numbness • Weakness • Paralysis on one side of the face • A dilated pupil in...

What is an aneurysm? An aneurysm is a bulging, weakened area in the wall of a blood vessel resulting in an abnormal widening or ballooning greater than 50% of the vessel's normal diameter (width). An aneurysm may occur in any blood vessel, but is most often seen in an artery rather than a vein. An aneurysm may be located in many areas of the body, such as blood vessels of the brain ( The shape of an aneurysm is described as being fusiform or saccular, which helps to identify a true aneurysm. The more common fusiform-shaped aneurysm bulges or balloons out on all sides of the blood vessel. A saccular-shaped aneurysm bulges or balloons out only on one side. A pseudoaneurysm, or false aneurysm, is not an enlargement of any of the layers of the blood vessel wall. A false aneurysm may be the result of a prior surgery or trauma. Sometimes, a tear can occur on the inside layer of the vessel. As a result, blood fills in between the layers of the blood vessel wall creating a pseudoaneurysm. A dissecting aneurysm is an aneurysm that occurs with a tear in the artery wall that separates the 3 layers of the wall, rather than ballooning out the entire wall. Because an aneurysm may continue to increase in size, along with progressive weakening of the artery wall, surgical intervention may be needed. Preventing rupture of an aneurysm is 1 of the goals of therapy. The larger an aneurysm becomes, the greater the risk for rupture (bursting). With rupture, life-threatening hemorrhage (uncontro...
