Progress And Future Challenges
Postoperative paraplegia and paraparesis have been the scourge of thoracoabdominal aortic repair since the inception of the procedure. However, with evolving surgical strategies, identification of predictors, and use of various adjuncts over the years, the incidence of spinal cord injury after thoracic/thoracoabdominal aortic repair has declined. Embracing a multimodality approach offers a good insight into combating this grave complication
How Is An Aaa Diagnosed
Doctors commonly find AAAs by chance during a routine exam. They also find them when testing for other issues, including pain in your abdomen. Doctors recommend an AAA screening for men ages 65 to 75 who have ever smoked.
If your doctor finds or thinks you have an AAA, they may order tests. Common tests include:
- Ultrasound or echocardiogram These use sound waves to create pictures of the inside of your body.
- Computed tomography scan The doctor uses X-rays to take pictures of your organs. Dye may be injected into your veins so your doctor can see them clearly.
- Magnetic resonance imaging This test uses magnets and radio waves to create pictures of your organs.
- Angiography This test uses dye and X-rays to look at the inside of your arteries. This can help your doctor see how much damage or blockage there is in your blood vessels.
If your doctor finds or thinks you might have an AAA, he or she might refer to you a specialist for treatment.
Watch Out 5 Warning Signs And Symptoms That Might Indicate Aortic Aneurysm
An aortic aneurysm is an abnormal enlargement or bulging of the wall of the aorta which is a major blood vessel that carries blood from heart to body. Aortic aneurysms include:
- Abdominal aortic aneurysm: occurs along the part of the aorta that passes through the abdomen.
- Thoracic aortic aneurysm: occurs along the part of the aorta that passes through the chest cavity.
If a ruptured aortic aneurysm could not be accurately diagnosed and effectively treated in time, it can cause life-threatening internal bleeding which leads to the increased chances of sudden death. Therefore, the notification of warning signs and symptoms of aortic aneurysm remains essentially important.
5 warning signs and symptoms that aortic aneurysm might be suspected include:
1) Chest tenderness or chest pain, dizziness or light-headedness, back pain, coughing up blood and loss of consciousness due to the ruptures.2) Sudden or intense abdominal pain, pulsating enlargement or tender mass in an abdomen caused by a bulge of aortic wall in the abdominal areas.3) Breathing difficulties such as shortness of breath related to the compression of the trachea caused by a bulge of aortic wall in the chest cavity.4) Swallowing difficulties caused by extrinsic compression of the esophagus due to the wall enlargement of thoracic aorta.5) Hoarseness from the compression of recurrent laryngeal nerve which supplies all intrinsic muscles of the larynx .

What Are The Symptoms Of Abdominal Aortic Aneurysms
About 3 out of 4 abdominal aortic aneurysms dont cause symptoms. An aneurysm may be found by X-ray, computed tomography scan, or magnetic resonance imaging that was done for other reasons. Since abdominal aneurysm may not have symptoms, its 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.

Although screening recommendations for brain aneurysms can vary depending in large part on your health insurance provider, having two close relatives who experienced a brain aneurysm rupture may signal a family predisposition, so screening is recommended for first-degree relatives of anyone who has had a brain aneurysm, says George P. Teitelbaum, MD, an interventional neuroradiologist at the Pacific Neuroscience Institute in Santa Monica, California.

Signs An Abdominal Aortic Aneurysm Has Burst
There are two major complications of abdominal aneurysm: rupture and dissection of the aorta. The first, whose incidence increases with the size of the aneurysm, refers to a breakage of the arterial wall resulting from pressure on the weak area. Dissection occurs when the layers of the arterial wall are torn. Blood then flows between the layers, forcing them apart.
This inhibits regular blood flow and may cause the aortic wall to burst. If your aortic wall bursts or breaks, you may suddenly feel extremely weak and dizzy, and possibly even lose consciousness.
Along with this comes intense and persistent abdominal pain that may radiate to your lower back or legs. Other symptoms include shortness of breath, sweatiness, rapid pulse and low blood pressure.

What Are The Types Of Aortic Aneurysm
A thoracic aortic aneurysm happens in the chest. Men and women are equally likely to get thoracic aortic aneurysms, which become more common with increasing age.4
Thoracic aortic aneurysms are usually caused by high blood pressure or sudden injury. Sometimes people with inherited connective tissue disorders, such as and Ehlers-Danlos syndrome, get thoracic aortic aneurysms.
Signs and symptoms of thoracic aortic aneurysm can include the following:
- Sharp, sudden pain in the chest or upper back
- Shortness of breath
- Trouble breathing or swallowing
An abdominal aortic aneurysm happens below the chest. Abdominal aortic aneurysms happen more often than thoracic aortic aneurysms.
Abdominal aortic aneurysms are more common in men and among people age 65 and older. Abdominal aortic aneurysms are more common among white people than among black people.5
Abdominal aortic aneurysms are usually caused by atherosclerosis , but infection or injury can also cause them.6
Abdominal aortic aneurysms often dont have any symptoms. If an individual does have symptoms, they can include the following:
- Throbbing or deep pain in the back or side
- Pain in the buttocks, groin, or legs

What Are The Complications Of An Aneurysm
If an aneurysm ruptures, it causes internal bleeding. Depending on the location of the aneurysm, a rupture can be very dangerous or life-threatening. An aneurysm in your neck can cause a blood clot that travels to your brain. If the clot cuts off blood flow to your brain, it causes a stroke. When a brain aneurysm ruptures, it causes a subarachnoid hemorrhage. Some people call this type of stroke a brain bleed. Typically people have what they call the worst headache of their life and then develop other symptoms like limb weakness, headache and trouble speaking.

What Can Parents Do
Kids often dont show signs of an aortic aneurysm. There are several things you can do to protect your child from having an emergency:
- Take your child to all well-child checkups.
- If doctors are watching your child for an aneurysm, go to all follow-up visits and testing.
- If your child needs medicine, give it as prescribed. Renew prescriptions before they run out. Ask the pharmacist or your doctor if youre not sure how to give a medicine.
- Tell your doctor if other people in your family have aneurysms.
- If your child has a genetic condition that causes aneurysms, ask about getting other family members tested. This can reveal an aneurysm before it causes problems.
- If your child had an aneurysm repaired, theres still a chance of having another one. Follow your doctors instructions about setting up regular ultrasounds, MRIs, or CT scans.
Diagnosing An Abdominal Aortic Aneurysm
AAAs that havent ruptured are most often diagnosed when a doctor is scanning or examining your abdomen for another reason.

About Abdominal Aortic Aneurysms
An abdominal aortic aneurysm is a swelling of the aorta the main blood vessel that leads away from the heart, down through the abdomen to the rest of the body.
The abdominal aorta is the largest blood vessel in the body and is usually around 2cm wide roughly the width of a garden hose. However, it can swell to over 5.5cm what doctors class as a large AAA.
Large aneurysms are rare, but can be very serious. If a large aneurysm bursts, it causes huge internal bleeding and is usually fatal.
The bulging occurs when the wall of the aorta weakens. Although what causes this weakness is unclear, smoking and high blood pressure are thought to increase the risk of an aneurysm.
AAAs are most common in men aged over 65. A rupture accounts for more than 1 in 50 of all deaths in this group.
This is why all men are invited for a screening test when they turn 65. The test involves a simple ultrasound scan, which takes around 10-15 minutes.

Techniques To Limit Ischemia
A number of techniques exist for maintaining perfusion to the viscera and spinal cord during open thoracoabdominal aortic aneurysm repair, including left heart bypass, balloon perfusion catheter placement in the visceral arteries, selective spinal drainage and cold crystalloid renal perfusion. There is limited evidence supporting these techniques.
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 blood vessels that carry oxygenated blood from your heart to other parts of your body. If an area in an artery wall weakens, the force of blood pumping through can result in a bulge or aneurysm.
Aneurysms usually arent painful. You might not know you have one unless it ruptures or bursts. If it does, it can be very dangerous or even fatal.

Postoperative And Rehabilitation Care
After repair, it is essential that the patient discontinue smoking, eat a healthy diet, and maintain a healthy weight. Physical and/or occupational therapy may be necessary. Obtaining computed tomography five years following the open repair management to exclude the late aortic dilation or pseudoaneurysm is recommended.
What Causes An Abdominal Aortic Aneurysm To Form
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:
-
Genetic factors
-
Connective tissue disorders such as , Ehlers-Danlos syndrome, Turner’s syndrome, and polycystic kidney disease
-
Congenital defects such as bicuspid aortic valve or coarctation of the aorta
-
Inflammation of the temporal arteries and other arteries in the head and neck
-
Infection such as syphilis, salmonella, or staphylococcus

How Can I Prevent Abdominal Aortic Aneurysms
Sometimes you cant prevent AAA, especially if you have a family history of the condition. But you can talk to your doctor right away if you experience any symptoms. Early detection and the right treatment may prevent the aneurysm from getting larger or rupturing.
You can also control many of the risk factors by:
- Stopping smoking.
- Exercising and eating a healthy diet.
- Managing your weight, blood pressure and cholesterol.
- Avoiding drinking too much alcohol.
Screening For Abdominal Aortic Aneurysm
Being male and smoking significantly increase the risk of abdominal aortic aneurysm. Screening recommendations vary, but in general:
- Men ages 65 to 75 who have ever smoked cigarettes should have a one-time screening using abdominal ultrasound.
- For men ages 65 to 75 who have never smoked, a doctor will decide on the need for an abdominal ultrasound based on other risk factors, such as a family history of aneurysm.
There isn’t enough evidence to determine whether women ages 65 to 75 who ever smoked cigarettes or have a family history of abdominal aortic aneurysm would benefit from abdominal aortic aneurysm screening. Ask your doctor if you need to have an ultrasound screening based on your risk factors. Women who have never smoked generally don’t need to be screened for the condition.

How Signs And Symptoms Can Look Different In Men And Women
Since research has historically looked at the symptoms men experience, aneurysms in women can be difficult to identify because their symptoms may not be so-called classic and they may not have the same symptoms men do, according to Kimberly Brown, MD, MPH, an emergency physician in Memphis. I think it has put women at a disadvantage, she says.
For example, women with abdominal aortic aneurysms may have vague abdominal pain and those with brain aneurysms may have a dull, persistent headache.
What Is Aortic Dissection
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. Aortic dissection can be a life-threatening emergency. The most commonly reported symptom of an aortic dissection is sudden, severe, constant chest or upper back pain, sometimes described as “ripping” or “tearing.” The pain may move from one place to another.
When a diagnosis of aortic dissection is confirmed, immediate surgery or stenting is usually done.

What Is Aortic Aneurysm
An aortic aneurysm is a balloon-like bulge in the aorta, the large artery that carries blood from the heart through the chest and torso.
Aortic aneurysms can dissect or rupture:
- The force of blood pumping can split the layers of the artery wall, allowing blood to leak in between them. This process is called a dissection.
- The aneurysm can burst completely, causing bleeding inside the body. This is called a rupture.
- Dissections and ruptures are the cause of most deaths from aortic aneurysms.

What Are The Different Types Of Aneurysms
An aneurysm can form in any of the arteries in your body. Aneurysms can occur in your heart, abdomen, brain or legs. The location determines the type of aneurysm.
Aortic aneurysms are by far the most common. They form in your aorta, your bodys largest artery. Your aorta carries blood out of your heart. Aneurysms that develop in arteries other than your aorta are called peripheral aneurysms.
Types of aneurysms include:
- Abdominal aortic aneurysm : Abdominal aortic aneurysms may form where your aorta carries blood into your abdomen .
- Cerebral aneurysms: Also called brain aneurysms, these aneurysms affect an artery in your brain. A saccular 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. Thoracic aortic aneurysms form in the upper part of your aorta, in your chest.
- Carotid aneurysm:Carotid artery aneurysms form in your carotid arteries. These blood vessels bring blood to your brain, neck and face. Carotid aneurysms are rare.
- 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.
