An aortic aneurysm is an abnormal bulge that occurs in the wall of the major blood vessel (aorta) that carries blood from your heart to your body. Aortic aneurysms can occur anywhere in your aorta and may be tube-shaped (fusiform) or round (saccular). Aortic aneurysms include: Abdominal aortic aneurysm. An abdominal aortic aneurysm occurs along. May 21, · back or flank pain, severe or worsening abdominal pain, a pulsating abdominal mass, or. feeling a pulse near the bellybutton.
An aortic aneurysm occurs when a weak spot in the wall of your aorta begins to bulge left. This can occur anywhere in your how to stop bleeding on baby finger. What are the symptoms of aortic aneurysm abdominal an aneurysm increases the risk of an aortic dissection — a tear in the lining of the aorta, shown in the image on the right.
An aortic aneurysm is an abnormal bulge that occurs in the wall of the major blood vessel aorta that carries blood from your ade to your body. Aortic aneurysms can occur anywhere in your aorta and may be tube-shaped fusiform or round saccular.
In some cases, an individual may have an abdominal aortic aneurysm and a thoracic aortic aneurysm. Having an aortic aneurysm increases your risk of developing an aortic dissection.
An aortic dissection occurs when a tear develops in the inner layer of the wall of the aorta. This causes one or more of the layers of the wall of the aorta to separate, which weakens the wall of the aorta.
Having an aortic aneurysm also eymptoms your risk that the aneurysm can burst rupture.

Pain is the most common symptom of an abdominal aortic aneurysm. The pain associated with an abdominal aortic aneurysm may be located in the abdomen, chest, lower back, or groin area. The pain may be severe or dull. Sudden, severe pain in the back or abdomen may mean the aneurysm is . Nov 20, · Back pain from an abdominal aortic aneurysm is felt in the lower part of the back, below the diaphragm. Aug 18, · Pain is the most common symptom when the aneurysm expands or ruptures. It often begins in the central abdomen and radiates to the back or flank. Other symptoms can occur depending upon where the aneurysm is located in the aorta and whether nearby structures are affected.
Please understand that our phone lines must be clear for urgent medical care needs. When this changes, we will update this website. Our vaccine supply remains limited. An aneurysm is a weak section of an artery wall. Pressure from inside the artery causes the weakened area to bulge out beyond the normal width of the blood vessel. An abdominal aortic aneurysm is an aneurysm in the lower part of the aorta, the large artery that runs through the torso. Older, long-term smokers are at especially high risk for abdominal aortic aneurysm.
Symptoms, when they do occur, include pain in the back or near the naval. An extremely sharp and severe pain may indicate rupture, requiring emergency medical treatment. Smaller, slow-growing aortic aneurysms may be treated with watchful waiting, lifestyle changes and medication. Large or fast-growing aortic aneurysms may require surgery. The aorta is the largest blood vessel in the body. It delivers oxygenated blood from the heart to the rest of the body.
An aortic aneurysm is a bulging, weakened area in the wall of the aorta. Over time, the blood vessel balloons and is at risk for bursting rupture or separating dissection. This can cause life threatening bleeding and potentially death. Aneurysms occur most often in the portion of the aorta that runs through the abdomen abdominal aortic aneurysm. An abdominal aortic aneurysm is also called AAA or triple A. A thoracic aortic aneurysm refers to the part of the aorta that runs through the chest.
Once formed, an aneurysm will gradually increase in size and get progressively weaker. Treatment for an abdominal aneurysm may include surgical repair or removal of the aneurysm, or inserting a metal mesh coil stent to support the blood vessel and prevent rupture. The more common shape is fusiform , which balloons out on all sides of the aorta. A saccular shape is a bulge in just one spot on the aorta. Sometimes this is called a pseudoaneurysm. It usually means the inner layer of the artery wall is torn, which can be caused by an injury or ulcer in the artery.
Many things can cause the breakdown of the aortic wall tissues and lead to an abdominal aortic aneurysm. The exact cause isn't fully known. But, atherosclerosis is thought to play an important role. Atherosclerosis is a buildup of plaque, which is a deposit of fatty substances, cholesterol, cellular waste products, calcium, and fibrin in the inner lining of an artery.
Risk factors for atherosclerosis include:. High cholesterol. High blood pressure. Connective tissue disorders such as Marfan syndrome , Ehlers-Danlos syndrome, Turner's syndrome, and polycystic kidney disease. About 3 out of 4 abdominal aortic aneurysms don't cause symptoms.
Since abdominal aneurysm may not have symptoms, it's called the "silent killer" because it may rupture before being diagnosed. Pain is the most common symptom of an abdominal aortic aneurysm.
The pain associated with an abdominal aortic aneurysm may be located in the abdomen, chest, lower back, or groin area. The pain may be severe or dull. Sudden, severe pain in the back or abdomen may mean the aneurysm is about to rupture.
This is a life-threatening medical emergency. Abdominal aortic aneurysms may also cause a pulsing sensation, similar to a heartbeat, in the abdomen. The symptoms of an abdominal aortic aneurysm may look like other medical conditions or problems. Always see your doctor for a diagnosis. This test uses X-rays and computer technology to make horizontal, or axial, images often called slices of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs.
CT scans are more detailed than standard X-rays. Magnetic resonance imaging MRI. This test uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body. Echocardiogram also called echo. This test evaluates the structure and function of the heart by using sound waves recorded on an electronic sensor that make a moving picture of the heart and heart valves, as well as the structures within the chest, such as the lungs and the area around the lungs and the chest organs.
Transesophageal echocardiogram TEE. This test uses echocardiography to check for aneurysm, the condition of heart valves, or presence of a tear of the lining of the aorta. TEE is done by inserting a probe with a transducer on the end down the throat.
Chest X-ray. This test uses invisible electromagnetic energy beams to make images of internal tissues, bones, and organs onto film. Arteriogram angiogram. This is an X-ray image of the blood vessels that is used to assess conditions such as aneurysm, narrowing of the blood vessel, or blockages. A dye contrast will be injected through a thin, flexible tube placed in an artery. The dye makes the blood vessels visible on an X-ray.
These tests are done to check the size and rate of growth of the aneurysm. Managing risk factors. Steps, such as quitting smoking, controlling blood sugar if you have diabetes, losing weight if overweight, and eating a healthy diet may help control the progression of the aneurysm. Used to control factors such as high cholesterol or high blood pressure. Abdominal aortic aneurysm open repair. A large incision is made in the abdomen to let the surgeon see and repair the abdominal aorta aneurysm.
A mesh, metal coil-like tube called a stent or graft may be used. This graft is sewn to the aorta, connecting one end of the aorta at the site of the aneurysm to the other end. The open repair is the surgical standard for an abdominal aortic aneurysm. Endovascular aneurysm repair EVAR. EVAR requires only small incisions in the groin. Using X-ray guidance and specially-designed instruments, the surgeon can repair the aneurysm by inserting the stent or graft inside the aorta. The graft material may cover the stent.
The stent helps hold the graft open and in place. A small aneurysm or one that doesn't cause symptoms may not require surgery until it reaches a certain size or is rapidly increasing in size over a short period of time.
Your doctor may recommend "watchful waiting. Surgery may be necessary if the aneurysm is large or fast growing, increasing chances of rupture.
Women with large aneurysms are more likely than men to suffer a rupture. For suprarenal above the kidneys AAA, only open surgery is available in the U. However, AAA at or below the kidneys may be treated by open or endovascular surgery. Not all patients can tolerate the risk of open surgery, so endovascular repair is a great option. Unfortunately, not all patients have the anatomy to qualify for endovascular repair. Consult your vascular surgeon about which technique is best for you.
Open aneurysm repair : A large incision is made in the abdomen to repair the aneurysm. Another incision is made in the aorta for the length of the aneurysm. A cylinder called a graft is used for the repair.
Grafts are made of polyester fabric or polytetrafluoroethylene PTFE, nontextile synthetic graft. This graft is sewn to the aorta, from just above the aneurysm site to just below it.
The artery walls are then sewn over the graft. Using X-ray guidance, a stent graft is inserted into the femoral artery and sent to the site of the aneurysm. A stent is a thin metal mesh framework shaped into a long tube, while the graft, a fabric covering the mesh, is made of a polyester fabric called PTFE. The stent holds the graft open and in place.
It may be more easily tolerated by high-risk patients. However, the graft can sometimes slip out of place and may later need to be fixed. Fenestrated stent graft : When the aneurysm is juxtarenal at the kidneys or involves the arteries of the kidneys, the prior standard treatment has been open surgery.
In , the FDA approved a fenestrated stent graft, now available in a few vascular surgery programs, including Johns Hopkins. An aortic dissection starts with a tear in the inner layer of the aortic wall of the thoracic aorta. The aortic wall is made up of 3 layers of tissue. When a tear occurs in the innermost layer of the aortic wall, blood is then channeled into the wall of the aorta separating the layers of tissues. This generates a weakening in the aortic wall with a potential for rupture.
