Aorta: Aortic Aneurysm Menu

Aorta Anatomy

Your Aorta

The aorta is the largest artery in the body and is the blood vessel that carries oxygen-rich blood away from the heart to all parts of the body.

The section of the aorta that runs through the chest is called the thoracic aorta and, as the aorta moves down through the abdomen it is called the abdominal aorta.

What Is An Aortic Aneurysm?

An aortic aneurysm is an abnormal enlargement or bulging of the wall of the aorta. An aneurysm can occur anywhere in the vascular tree. The bulge or ballooning may be defined as a:

  • Fusiform: Uniform in shape, appearing equally along an extended section and edges of the aorta.
  • Saccular aneurysm: Small, lop-sided blister on one side of the aorta that forms in a weakened area of the aorta wall.

An aneurysm can develop anywhere along the aorta:

  • Aneurysms that occur in the section of the aorta that runs through the abdomen (abdominal aorta) are called abdominal aortic aneurysms.
  • Aortic aneurysms that occur in the chest area are called thoracic aortic aneurysms and can involve the aortic root, ascending aorta, aortic arch or descending aorta.
  • Aneurysms that involve the aorta as it flows thru both the abdomen and chest are called thoracoabdominal aortic aneurysms.

Abdominal aortic aneurysms and thoracic aneurysm are not the only type of aneurysm. Aneurysms can develop in other blood vessels:

  • Popliteal: an aneurysm in the artery behind the knee
  • Renal: an aneurysm in the kidney; a very rare condition
  • Visceral: an aneurysm in an internal organ and/or intestines

What are the Symptoms of Aortic Aneurysm?

Symptoms of a thoracic aortic aneurysm (affecting upper part of aorta in chest):

  • Pain in the jaw, neck, upper back or chest
  • Coughing, hoarseness or difficulty breathing
  • Learn more about thoracic aortic aneurysm

Symptoms of an abdominal aortic aneurysm (affecting lower part of aorta in abdomen):

  • Pulsating enlargement or tender mass felt by a physician when performing a physical examination
  • Pain in the back, abdomen, or groin not relieved with position change or pain medication
  • Learn more about abdominal aortic aneurysm

Early diagnosis of an aneurysm is critical to managing the condition and reducing the risk of rupture. If you have these symptoms, call your doctor right away.

An aneurysm is the enlargement of an artery caused by weakness in the arterial wall. Often there are no symptoms, but a ruptured aneurysm can lead to fatal complications.

An aneurysm refers to a weakening of an artery wall that creates a bulge, or distention, of the artery.

Most aneurysms do not show symptoms and are not dangerous. However, at their most severe stage, some can rupture, leading to life-threatening internal bleeding.

The Centers for Disease Control and Prevention (CDC) advise that aortic aneurysms contribute to over 25,000 deaths in the United States (U.S.) each year.

Around 30,000 brain aneurysms rupture in the U.S. each year. An estimated 40 percent of these cases cause death within 24 hours.

Fast facts on aneurysms

  • Aneurysms affect a variety of arteries. The most significant aneurysms affect the arteries supplying the brain and the heart. An aortic aneurysm affects the body’s main artery.
  • The rupture of an aneurysm causes internal bleeding.
  • The risk of an aneurysm developing and rupturing varies between individuals. Smoking and high blood pressure are major risk factors for the development of an aneurysm.
  • Some types of aneurysm may need surgical treatment to prevent rupture. Doctors will only operate on others if they are life-threatening.

Types

Aneurysm rupture
The rupture of an aneurysm can be fatal.

Aneurysms are classified by their location in the body. The arteries of the brain and heart are the two most common sites of a serious aneurysm.

The bulge can take two main shapes:

  • Fusiform aneurysms bulge all sides of a blood vessel
  • Saccular aneurysms bulge only on one side

The risk of rupture depends on the size of the bulge.

Aortic aneurysm

The aorta is the large artery that begins at the left ventricle of the heart and passes through the chest and abdominal cavities. The normal diameter of the aorta is between 2 and 3 centimeters (cm) but can bulge to beyond 5 cm with an aneurysm.

The most common aneurysm of the aorta is an abdominal aortic aneurysm (AAA). This occurs in the part of the aorta that runs through the abdomen. Without surgery, the annual survival rate for an AAA of over 6 cm is 20 percent .

AAA can rapidly become fatal, but those that survive the transfer to a hospital have a 50 percent chance of overall survival.

Less commonly, a thoracic aortic aneurysm (TAA) can affect the part of the aorta running through the chest. TAA has a survival rate of 56 percent without treatment and 85 percent following surgery. It is a rare condition, as only 25 percent of aortic aneurysms occur in the chest.

Cerebral aneurysm

Aneurysms of the arteries that supply the brain with blood are known as intracranial aneurysms. Due to their appearance, they are also known as “berry” aneurysms.

A ruptured aneurysm of the brain can be fatal within 24 hours. Forty percent of brain aneurysms are fatal, and around 66 percent of those who survive will experience a resulting neurological impairment or disability.

Ruptured cerebral aneurysms are the most common cause of a type of stroke known as subarachnoid hemorrhage (SAH).

Peripheral aneurysm

An aneurysm can also occur in a peripheral artery. Types of peripheral aneurysm include :

  • Popliteal aneurysm: This happens behind the knee. It is the most common peripheral aneurysm.
  • Splenic artery aneurysm: This type of aneurysm occurs near the spleen.
  • Mesenteric artery aneurysm: This affects the artery that transports blood to the intestines.
  • Femoral artery aneurysm: The femoral artery is in the groin.
  • Carotid artery aneurysm: This occurs in the neck.
  • Visceral aneurysm: This is a bulge of the arteries that supply blood to the bowel or kidneys.

Peripheral aneurysms are less likely to rupture than aortic aneurysms.

Treatment

Not all cases of unruptured aneurysm need active treatment. When an aneurysm ruptures, however, emergency surgery is needed.

Aortic aneurysm treatment options

The doctor may monitor an unruptured aortic aneurysm, if no symptoms are evident. Medications and preventive measures may form part of conservative management, or they may accompany active surgical treatment.

A ruptured aneurysm needs emergency surgery. Without immediate repair, patients have a low chance of survival.

The decision to operate on an unruptured aneurysm in the aorta depends on a number of factors related to the individual patient and features of the aneurysm.

These include:

  • the age, general health, coexisting conditions and personal choice of the patient
  • the size of the aneurysm relative to its location in the thorax or abdomen, and the aneurysm’s rate of growth
  • the presence of chronic abdominal pain or risk of thromboembolism, as these may also necessitate surgery

A large or rapidly growing aortic aneurysm is more likely to need surgery. There are two options for surgery:

  • open surgery to fit a synthetic or stent graft
  • endovascular stent-graft surgery.

In endovascular surgery, the surgeon accesses the blood vessels through a small incision near the hip. Stent-graft surgery inserts an endovascular graft through this incision using a catheter. The graft is then positioned in the aorta to seal off the aneurysm.

In an open AAA repair, a large incision is made in the abdomen to expose the aorta. A graft can then be applied to repair the aneurysm.

Endovascular surgery for the repair of aortic aneurysms carries the following risks:

  • bleeding around the graft
  • bleeding before or after the procedure
  • blockage of the stent
  • nerve damage, resulting in weakness, pain or numbness in the leg
  • kidney failure
  • reduced blood supply to the legs, kidneys or other organs
  • erectile dysfunction
  • unsuccessful surgery that then needs further open surgery
  • slippage of the stent

Some of these complications, such as bleeding around the graft, will lead to further surgery.

Cerebral aneurysm treatment options

Cerebral aneurysm
A ruptured intracerebral aneurysm will usually need emergency surgery.

In the case of a brain aneurysm, the surgeon will normally operate only if there is a high risk of rupture. The potential risk of brain damage resulting from surgical complications is too great.

As for AAA, the likelihood of a rupture depends on the size and location of the aneurysm.

Instead of surgery, patients receive guidance on how to monitor and manage the risk factors for a ruptured brain aneurysm, for example, monitoring blood pressure .

If a ruptured cranial aneurysm results in a subarachnoid hemorrhage, surgery is likely. This is considered a medical emergency.

This procedure would aim to close off the ruptured artery in the hope of preventing another bleed.

Symptoms

Most aneurysms are clinically silent. Symptoms do not usually occur unless an aneurysm ruptures.

However, an unruptured aneurysm may still obstruct circulation to other tissues. They can also form blood clots that may go on to obstruct smaller blood vessels. This is a condition known as thromboembolism. It can lead to ischemic stroke or other serious complications.

Aneurysm severe pain
Aneurysms are generally symptomless, but their complications can cause severe chest pain.

Rapidly growing abdominal aneurysms are sometimes associated with symptoms. Some people with abdominal aneurysms report abdominal pain, lower back pain , or a pulsating sensation in the abdomen.

Similarly, thoracic aneurysms can affect nearby nerves and other blood vessels, potentially causing swallowing and breathing difficulties, and pain in the jaw, chest, and upper back.

Symptoms can also relate to the cause of an aneurysm rather than the aneurysm itself. For example, in the case of an aneurysm caused by vasculitis, or blood vessel inflammation , a person may experience fever , malaise, or weight loss.

Complications

The first signs of a previously undetected aneurysm could be complications upon rupture. Symptoms tend to result from a rupture rather than the aneurysm alone.

Most people living with an aneurysm do not experience any complications. However, in addition to thromboembolism and rupture of the aorta, complications can include:

  • Severe chest or back pain: Severe chest or back pain may arise following the rupture of an aortic aneurysm in the chest.
  • Angina: Certain types of aneurysm can lead to angina , another type of chest pain. Angina can lead to myocardial ischemia and heart attack .
  • A sudden extreme headache: If a brain aneurysm leads to SAH, the main symptom is a sudden, severe headache .

Any rupture of an aneurysm may cause pain, low blood pressure, a rapid heart rate, and lightheadedness. Most people with an aneurysm will not experience any complications.

Causes

An aneurysm can happen in any part of the body. Blood pressure can more easily distend a weakened arterial wall.

Further research is necessary to confirm why an artery wall weakens to cause an aneurysm. Some aneurysms, though less common, are present from birth as an arterial defect.

Aortic dissection

Aortic dissection is one identifiable cause of an aortic aneurysm. The arterial wall has three layers. Blood can burst through a tear in the weakened wall of the artery, splitting these layers. It can then fill the cavity surrounding the heart.

If the tear occurs on the innermost layer of the arterial wall, blood channels into and weakens the wall, increasing the risk of rupture.

People with aortic dissection often describe abrupt and excruciating chest pain. This pain can travel as the dissection progresses along the aorta. It may, for example, radiate to the back.

Dissection leads to compression. Compression prevents blood from returning to the heart. This is also known as a pericardial tamponade.

Risk factors

There are some lifestyle choices and physical characteristics that can increase the chance of an aneurysm.

  • smoking tobacco
  • hypertension , or high blood pressure
  • poor diet
  • inactive lifestyle
  • obesity

Smoking is by far the most common risk factor, especially in cases of AAA. Tobacco use has been shown not only to increase cardiovascular disease and the risk of an aneurysm but also increase the risk of rupture once an aneurysm has taken effect.

Diagnosis

Aneurysms often remain undetected. Screening aims to identify people who need monitoring or treatment.

The US Preventive Services Task Force (USPSTF) recommends ultrasound screening for signs of AAA for all men aged 65 to 75 years who have smoked 100 cigarettes or more in their lives.

The taskforce does not recommend routine screening for women, whether they have smoked or not, as women have a lower risk of AAA.

If symptoms appear, an MRI scan can identify an aneurysm that has not yet ruptured. CT scans are usually preferred for ruptured aneurysms, especially if there is a risk of bleeding on the brain.

In cases of a severe or ruptured aneurysm in the brain or heart that needs emergency surgery, an angiogram can identify the exact area in need of repair. A catheter is inserted into a blood vessel in the thigh, under local anesthetic, and the catheter is then threaded through to the relevant part of the body.

The doctor applies a dye, helping to identify the area of the heart or brain that needs treatment.

Outlook

A person can live with an unruptured aneurysm and not notice it. However, if it bursts, it can be life-threatening.

It can lead to :

  • hemorrhagic stroke
  • hydrocephalus
  • coma
  • vasospasm
  • long- or short-term brain damage

Vasospasm is the main cause of disability or death following a burst aneurysm.

Factors affecting the chance of making a full recovery include the type and extent of the aneurysm, the overall health of the person before it ruptured, and how quickly they receive treatment.

Around 40 percent of cases of ruptured aneurysm will be fatal within the first 24 hours. In up to 25 percent of people, complications will be fatal within 6 months.

Prevention

Preventing an aneurysm is not always possible, as some are congenital, meaning they are present from birth.

However, some lifestyle choices can affect the risk:

Smoking is a risk factor for both aortic aneurysms and the rupture of an aneurysm anywhere in the body. Quitting smoking can reduce the risk of a severe aneurysm.

Managing blood pressure can also minimize the risk of an aneurysm. Healthful blood pressure can be achieved through dietary measures, regular exercise, and medications.

Obesity can put extra pressure on the heart, so taking these steps is important for reducing stress on the artery walls.

A healthful diet can also reduce cholesterol and decrease the risk of atherosclerosis . Fusiform aneurysms are often linked to atherosclerosis.

Anyone diagnosed with an aneurysm and prescribed a conservative treatment plan can work with a healthcare practitioner to address any risk factors.
