What is the diagnosis and treatment of aortic aneurysm?
The goal of abdominal aortic aneurysm treatment is to prevent an aneurysm from rupturing. Treatment may involve careful monitoring or surgery. Which treatment you have depends on the size of the aortic aneurysm and how fast it's growing. Medical monitoring. A doctor might recommend this option, also called watchful waiting, if the abdominal aortic aneurysm is small and isn't causing symptoms.
What are the signs and symptoms of aortic dissection?
- fainting,
- dizziness, or
- abdominal pain radiating to the flank or back in the case of a dissection in the abdominal part of the aorta.
How serious is aortic dissection?
Aortic dissection is life threatening. The condition can be managed with surgery if it is done before the aorta ruptures. Less than one half of people with a ruptured aorta survive. Those who survive will need lifelong, aggressive treatment of high blood pressure.
What causes a dissecting aneurysm of the aorta?
What causes aortic dissection? Certain conditions make a tear in the wall of the aorta more likely. High blood pressure over a long period of time may weaken the wall of the aorta, making it more likely to tear. People who already have an enlarged aorta (aortic aneurysm) are also at increased risk of aortic dissection.Some people are born with a condition that causes a weakened wall of the aorta.
What is the most common cause of aortic aneurysm?
Thoracic aortic aneurysms are usually caused by high blood pressure or sudden injury. Sometimes people with inherited connective tissue disorders, such as Marfan syndrome and Ehlers-Danlos syndrome, get thoracic aortic aneurysms.
What is the most common cause of dissecting abdominal aortic aneurysm?
Abdominal aortic aneurysm risk factors include: Tobacco use. Smoking is the strongest risk factor for aortic aneurysms. Smoking can weaken the walls of the aorta, increasing the risk of aortic aneurysm and aneurysm rupture.
How do you get an aortic dissection?
It's believed that most aortic dissections are caused by an underlying vulnerability that may be inherited. In others, the stress to the aortic wall from constant high blood pressure can weaken the aorta wall in susceptible people, resulting in a tear and dissection.
Are there warning signs before aortic dissection?
Aortic dissection may not always present with symptoms that suggest an acute cardiovascular event. Classical acute aortic dissection has been described as presenting with sudden, severe chest, back, or abdominal pain that is characterised as ripping or tearing in nature.

Can you prevent aortic dissection?
You can reduce your risk of aortic dissection by making lifestyle changes that include monitoring and controlling your blood pressure, maintaining a healthy weight, quitting smoking, and wearing a seatbelt while in a car. Learn more about how these lifestyle changes can help you prevent aortic dissection.
Can aortic dissection be sudden?
Aortic Dissection Symptoms Symptoms usually begin suddenly and may include severe chest or back pain that may be felt as sharp or stabbing or as a tearing. Sometimes, the pain moves to the neck, jaw, shoulder, arm, or abdomen. Acute aortic dissection can be life-threatening and requires immediate treatment.
Is death by aortic aneurysm painful?
Symptoms of an AAA A ruptured aneurysm can cause massive internal bleeding, which is usually fatal. Around 8 out of 10 people with a rupture either die before they reach hospital or don't survive surgery. The most common symptom of a ruptured aortic aneurysm is sudden and severe pain in the abdomen.
Does aortic dissection run in families?
About 20 percent of people with thoracic aortic aneurysm and dissection have a genetic predisposition to it, meaning it runs in the family. This type is known as familial thoracic aneurysm and dissection. Many people don't know they have a genetic predisposition to thoracic aortic aneurysm and dissection.
What is the life expectancy of someone who has had an aortic dissection?

Signs and symptoms that a thoracic aortic aneurysm has ruptured or dissected include: Sharp, sudden pain in the upper back that spreads downward. Pain in the chest, jaw, neck or arms. Difficulty breathing.
What is the most common site for a dissecting aneurysm?
The most common location of an aneurysm is the aorta, which carries oxygenated blood from the heart to the body. The thoracic aorta is the short segment of the aorta in the chest cavity.
Where is aortic dissection most common?
The most common site of dissection is the first few centimeters of the ascending aorta, with 90% occurring within 10 cm of the aortic valve. The second most common site is just distal to the left subclavian artery. Between 5% and 10% of dissections do not have an obvious intimal tear.
What is the most common type of aortic dissection?
Type A Aortic Dissection Type A is the most common type of aortic dissection and is more likely to be acute than chronic. This makes it more dangerous than type B dissections because it is more likely to cause the aorta to rupture, leading to a potentially fatal heart condition.
What is the most common abdominal aortic aneurysm?
Infrarenal abdominal aortic aneurysms are the most common aneurysms of the aorta. Screening ultrasound has helped detect AAA and allows for surveillance in asymptomatic patients with a diameter < 5 cm.
What is the name of the aneurysm that occurs along the aorta?
Aortic aneurysms include: Abdominal aortic aneurysm. An abdominal aortic aneurysm occurs along the part of the aorta that passes through the abdomen. Thoracic aortic aneurysm. A thoracic aortic aneurysm occurs along the part of the aorta that passes through the chest cavity.
What is the term for a weak spot in the wall of the aorta?
Aortic dissection and aortic aneurysm. Aortic dissection and aortic aneurysm. An aortic aneurysm occurs when a weak spot in the wall of your aorta begins to bulge (left). This can occur anywhere in your aorta.
Where is the aortic aneurysm located?
Aortic aneurysms can occur anywhere in the aorta and may be tube-shaped (fusiform) or round (saccular).
Can an aortic aneurysm burst?
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 increases your risk that the aneurysm can burst (rupture).
What is Stanford type A aortic dissection?
Stanford Type A Aortic Dissection: This type of dissection occurs in the first part of the aorta, closer to the heart, and can be immediately life-threatening. It usually requires emergency open chest surgery to repair or replace the first segment of the aorta where the tear started (ascending aorta +/- the arch and/or aortic valve). This is a more common type of dissection than Type B, and the dissection of the aorta usually extends through the entire length of the aorta.
What is an aortic rupture?
An aortic rupture is a complete tear through all three layers of the aorta — like a rip or a hole — in the wall of the aorta. Blood bursts through the hole into the surrounding body cavity.
Why does the aorta wall weaken in some people and not others?
In others, the stress to the aortic wall from constant high blood pressure can weaken the aorta wall in susceptible people, resulting in a tear and dissection.
Why does the aorta bulge?
Over time, the stress of blood flow between aortic layers can cause the weakened area of the aorta to bulge like a balloon, stretching the aorta into what is called an aneurysm – with the risk for late rupture and associated death. Many patients may require future surgeries to repair late developing aneurysms.
How do you know if your aorta is tearing apart?
When dissection first occurs and the layers of the aorta are forced apart, it usually feels like a severe, sharp, tearing pain in your chest and back. It feels like your aorta is ripping apart. Other symptoms include. Shortness of breath. Fainting or dizziness.
How long can aortic dissection surgery be delayed?
In some Type B aortic dissection cases, medication alone may be used to treat the dissection initially. Surgery may be able to be delayed for months to years depending on the severity of the tear and extent of dissection.
Why does aortic dissection happen?
Aortic dissection happens because there is an underlying, slow breakdown of the cells that make up the walls of your aorta. The breakdown has likely been going on silently for many years before the weakened area of the aortic wall finally gives way, resulting in a tear, which leads to the aortic dissection.
What is the section of the aorta that runs through the abdomen called?
Aneurysms that occur in the section of the aorta that runs through the abdomen (abdominal aorta) are called abdominal aortic aneurysms.
How to tell if you have an abdominal aortic aneurysm?

How to find aneurysms?
Aneurysms can be detected by physical exam, on a basic chest or stomach x-ray, or by using ultrasound. The size and location can be found through echocardiography or radiological imaging, such as arteriography, magnetic resonance imaging (MRI), and computed tomography (CAT or CT) scanning. See Diagnostic Tests & Procedures.
Why do my arteries bulge?
Atherosclerosis (a build-up of plaque in the arteries), high blood pressure, and smoking increase your risk. Deep wounds, injuries, or infections can also cause blood vessels to bulge. In some cases, an aneurysm may be a congenital condition, meaning you are born with it.

Can you die from an aortic aneurysm?
You can die if an aneurysm causes this main artery to burst and it is not treated in time. An aortic aneurysm may be located in your chest (thoracic aneurysm), but most are located below the kidneys in the lower stomach area (abdominal aneurysms).
What is the pathogenesis of an aortic aneurysm?
The pathogenesis is believed to involve compromised intercostal and lumbar arteries, which supply the spinal cord. For the most part the lesions of the spinal cord in reports of these cases have been characterized by selective necrosis of the gray matter, involving the thoracolumbar cord (Thompson, 1956; Lindsay and Hurst, 1967 ). In the case described by Kepes (1965), there was selective necrosis of the gray matter akin to what has been described experimentally with transient occlusion of the abdominal aorta ( Fig. 29.6) ( De Girolami and Zivin, 1982 ).
What is dissecting aortic hematoma?
Whereas aortic dissection has been used synonymously with dissecting aortic aneurysm , dissecting aortic hematoma is also appropriate to describe this condition. Pathologic examination of dissecting aortic hematomas after surgery or at autopsy may be unable to distinguish whether the abnormalities in the media and intima are primary or secondary. Hematomas within the aortic wall are thought to arise from tears in the intima or disruption of the vasa vasorum within the media. Connective tissue disorders affect the integrity of the media of blood vessels and therefore predispose them to rupture of the vasa vasorum. However, they can also weaken vessel walls, which subsequently stretch, tearing the intimal lining. Atherosclerosis and systemic hypertension are thought to be the most common causes of aortic dissection initiated by intimal tears.
What causes hemoptysis in pulmonary artery?
Aneurysms of the pulmonary artery remain rare causes of hemoptysis. 118 Mycotic aneurysms are commonly caused by Mycobacterium tuberculosis, syphilis, S. aureus, and streptococcal species. Poststenotic dilation may occur in congenital pulmonary artery strictures. Structural vascular abnormalities such as Marfan syndrome can also affect the pulmonary arteries.
How does aortic dissection affect the spinal cord?
The effects of the dissecting process depend not only on the extent of the dissection but also on the proximity to critical vessels supplying regions of the spinal cord that have poor collateral circulation. When aortic dissection causes symptoms of focal ischemia, blockage of the ostia of the aortic branches is the presumed mechanism. Ischemia of the spinal cord causes predominantly lower motor neuron signs because the gray matter needs more oxygen than the white matter does. Animal experiments have shown that the overall oxygen needs of the spinal cord are about two fifths that of cerebral tissue. Indeed, during aortic surgery, the spinal cord blood supply can be occluded for up to 30 minutes without causing postoperative neurologic deficits. This phenomenon may partly explain how extensive aortic dissections can cause either no symptoms or only transient ones.
What are the complications of pulmonary arteriovenous malformations?
Pulmonary arteriovenous malformations (PAVMs) present with progressive hypoxemia, paradoxical emboli, or bleeding complica tions including hemoptysis or hemothorax. 124 Although the majority of these lesions are likely congenital telangiectasias that have enlarged over years, 125 acquired arteriovenous malformations (AVMs) have been noted after chest surgery and trauma and have been associated with actinomycosis, schistosomiasis, cirrhosis, and metastatic carcinoma. 126 The hereditary Osler-Weber-Rendu disease (OWR) is associated with hemorrhagic telangiectasias in many organ systems. Approximately 15% of OWR patients have pulmonary arteriovenous aneurysms, 127 and up to 36% of patients with a single PAVM and 57% of patients with multiple PAVMs have OWR. 128 Bronchial artery telangiectasias with bleeding 129 have also been described, although the pathogenic relationship to pulmonary artery telangiectasias remains speculative. Treatment of PAVMs, particularly if hemoptysis has developed, is to embolically obliterate the lesion. 130 This should be done by an experienced operator because paradoxical emboli to the systemic arterial circulation are more than a theoretical concern.
What are the rare vascular-to-airway fistulas?
Some of the rare vascular-to-airway fistulas that have been described include (1) carotid artery to trachea in a patient with occult laryngeal cancer 111; (2) various abdominal arterial supplies to pulmonary sequestrations 112; (3) syphilitic aneurysms of the ascending aorta and other thoracic arteries to pulmonary parenchyma 113; (4) coronary artery bypass grafts to pulmonary parenchyma 114; (5) splenopulmonary shunt in portal hypertension following splenectomy 115; (6) left ventricular pseudoaneurysms 116 to pulmonary parenchyma; and (7) vena caval-bronchial fistulas. 117 Two of the more common bronchovascular communications, aortobronchial fistulas and pulmonary artery aneurysms, deserve comment.
What causes lower motor neuron signs?
When aortic dissection causes symptoms of focal ischemia, blockage of the ostia of the aortic branches is the presumed mechanism. Ischemia of the spinal cord causes predominantly lower motor neuron signs because the gray matter needs more oxygen than the white matter does.
What is the aorta?
The aorta is the largest blood vessel in the body. It is an artery and carries blood from the heart and descends through the chest and the tummy (abdomen). Many arteries come off the aorta to supply blood to all parts of the body. At about the level of the hips, the aorta divides into two arteries, one going to each leg.
What causes aortic dissection?
Certain conditions make a tear in the wall of the aorta more likely. High blood pressure over a long period of time may weaken the wall of the aorta, making it more likely to tear. People who already have an enlarged aorta ( aortic aneurysm) are also at increased risk of aortic dissection.
What symptoms does aortic dissection cause?
Aortic dissection may cause severe chest pain and shortness of breath. The symptoms may be very similar to those of a heart attack. The chest pain starts suddenly and is often described as a tearing, ripping or shearing feeling. The pain often spreads to the neck or down the back.
How is aortic dissection diagnosed?
Initial investigations to diagnose aortic dissection and rule out a heart attack may include:
What is the outlook (prognosis)?
Aortic dissection is often fatal if the blood-filled channel within the wall of the aorta ruptures through to the outside aortic wall (this is called aortic rupture). However, early diagnosis and treatment of aortic dissection can greatly improve survival.
Can aortic dissection be prevented?
The most effective ways to prevent aortic dissection are to take regular medicine to control blood pressure if you are found to have high blood pressure. You can also reduce your risk by reducing the risk of damage to your heart and arteries. This can be achieved by eating a healthy diet, taking regular exercise, keeping to an ideal body weight and avoiding smoking.
What is a dissection of the aorta?
An aortic dissection is a serious condition in which the inner layer of the aorta tears. Blood then surges through the tear, causing the inner and middle layers of the aorta to separate (dissect).
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.
What are the risk factors for aortic aneurysm?
Diseases and unhealthy behaviors that damage your heart and blood vessels also increase your risk for aortic aneurysm. Smoking is the most important behavior related to aortic aneurysm.
How are aortic aneurysms treated?
The two main treatments for aortic aneurysms are medicines and surgery. Medicines can lower blood pressure and reduce risk for an aortic aneurysm. Surgery can repair or replace the affected section of the aorta.
