Aneurysms usually do not cause any symptoms until they become very large or rupture. Aneurysms in the abdominal aorta are often found coincidentally when the individual undergoes a medical test or procedure for some other reason.
Chest pain and back pain are the 2 most common symptoms of large aneurysms.
Almost any unusual sensation or feeling in the upper chest or back, however, may be due to an aneurysm of the aorta.
Chest pain is usually the first sign of aortic dissection. Many people describe a tearing or ripping pain in the chest when the aorta enlarges to a critical size and ruptures/dissects. Besides pain, increased sweating, a fast heart rate, rapid breathing, dizziness, and shock may occur.
Some people describe the following symptoms of an aortic aneurysm:
A pulsating bulge or a strong pulse in the abdomen
Feeling of fullness after minimal food intake
Nausea
Vomiting
Where the aorta widens into a bulge, blood clots (thrombi) are more likely to form. If a piece of a blood clot breaks off, it travels through the circulatory system until it lodges somewhere. The clot can cut off blood flow to any area of the body. Symptoms depend on which part of the body is deprived of blood.
In the most serious cases, the broken off fragments can cause stroke or heart attack. The fragments can also cause one or more vital body organs, such as the lungs, liver, or kidneys, to stop functioning properly.
In less serious cases, it might cause numbness, weakness, tingling, pallor, or coldness in an arm or leg, loss of sensation, light-headedness, or localized pain.
Any of these symptoms can also occur with dissection of the aorta. The pain in the chest or pain may be particularly severe, and may mimic a heart attack.
In ruptured aneurysm or dissection, internal bleeding will occur. If you have any of these symptoms along with the other symptoms of aortic aneurysm, you could be in danger and must seek emergency medical care right away. Other symptoms include the following:
Light-headedness
Confusion
Weakness
Shortness of breath
Rapid heart beat
Sweating
Numbness or tingling
Loss of consciousness (fainting)
This is a medical emergency. If the bleeding is uncontrolled, your blood pressure will drop dangerously low. Your organs will not receive enough blood to function normally. This is called circulatory collapse, or just "shock."
This is a life-threatening condition.
You lose consciousness if your brain does not receive enough blood.
Your other organs may start to fail.
Your heart can stop beating. This is called cardiac arrest and is often fatal.
Circulatory System
Circulatory System, or cardiovascular system, in humans, the combined function of the heart, blood, and blood vessels to transport oxygen and nutrients to organs and tissues throughout the body and carry away waste products. Among its vital functions, the circulatory system increases the flow of blood to meet increased energy demands during exercise and regulates body temperature.
