Aorta (Definition)

The aorta is the largest artery in the body, leaving directly from the left ventricle of the heart to supply blood to the entire body. It is made of elastic tissue layers called "intima" and is subject to damage by high blood pressure, smoking, cholesterol, ...Read more

What is the pathophysiology of abdominal aortic aneurysm?

What is the pathophysiology of abdominal aortic aneurysm?

Inflammatory process: The exact mechanism for AAA formation is not known. There are several etiologies/theories. The most widely accepted is that aaas form due to an inflammatory process in the wall of the aorta associated with atherosclerosis. Inflammatory cells are thought to degrade structural proteins (such as elastin) in the wall of the aorta, weakening it and allowing for aneurysm formation. ...Read more

What is the largest abdominal aortic aneurysm repaired?

Largest AAA repaired: You shouldn't think about it as, " is it too big to repair?" many anatomic details as well as a person's overall medical condition go into the decision as to if an aneurysm can be repaired. Its overall size is not a main consideration (though if its still small, they can usually be watched without repair). ...Read more

What is the post-operative care of abdominal aortic aneurysm?

What is the post-operative care of abdominal aortic aneurysm?

Depends: There is a big difference between an open repair and an endovascular repair. Open repairs require aggressive cardio-pulmonary resuscitation post-op. Depending on the extent of the repair patients are often kept intubated the first night. Endovascular procedures are typically less of a physiological burden on the body and patients are extubated the same day and typically go home the next day. ...Read more

What are the symptoms of an abdominal aortic aneurysm?

Usually none: Most of AAA have no symptoms and discovered by routine physical exams, screening ultrasound or incidental finding on ct scans. If symptomatic then usually pain in upper to mid abdomen sometimes radiating to the back or just back pain , rupture with severe pain and shock , sometimes present as clots traveling to the legs with acute pain or blue toes. Rare type is infected or inflammatory /fever. ...Read more

What is the presumed cause of most aneurysms of the abdominal aorta?

What is the presumed cause of most aneurysms of the abdominal aorta?

Several theories: Most common belief is that aneurysms develop due to some inherent weakness in the artery's muscular layer due to an imbalance of collagen metabolism or genetic collagen abnormalities. The only independent risk of aneurysm growth is high blood pressure and smoking. ...Read more

Why coarctation of aorta in infantile, cause passes of the blood from pulmonary artery to the aorta through pda?

Why coarctation of aorta in infantile, cause passes of the blood from pulmonary artery to the aorta through pda?

Plumbing!: Blood must get to the body, else the fetus would not survive. The same is true once the baby is born. In utero, blood flows from pulm artery (pa) to aorta (ao) normally. Once born, the blood continues to flow this way so that blood can get to the body. When the PDA closes, the child becomes very sick. ...Read more

What is coarctation of the aorta?

What is coarctation of the aorta?

Narrowing of alrta: Coarctation is a narrowing of the main vessel (aorta). It leads to hypertension and increased work for the heart. Untreated it leads to stroke coronary disease and death. Therapeutic options are surgery or catheter therapy. ...Read more

What are the causes coarctation of the aorta?

What are the causes coarctation of the aorta?

Narrowing: Coarctation usually occurs near the site of the pda. The PDA is a normal channel in the fetal circulation which helps blood bypass the lungs (since fetuses don't breathe). When the baby is born, the PDA constricts and closes. In some patients, the aorta also become constricted and leads to coarctation. ...Read more

What complications can accompany the coarctation of the aorta?

Several: Aortic coarctation is associated with hypertension (high blood pressure). This can develop even years later, after successful surgical correction, due to a diffuse dysfunction of cells lining artery walls. This can also affect coronary arteries (causing atherosclerosis), and the adjacent (non-coarcted) aorta, with risk of aneurysm formation or dissection of the aorta wall. ...Read more

In x-ray findings, the Dr. said that there were extensive artherosclerotic, changes in the visualized abdominal aorta. What does this mean?

Calcium: There is calcium in the wall of the aorta +/- iliac arteries. This is arteriosclerosis or "hardening" of the arteries. This may not need treatment. ( other than not smoking, keeping BP and cholesterol under control). A vascular surgeon can tell you if additional testing or treatment is necessary. ...Read more

Is it a problem if you have a beating abdominal aorta?

Aorta: Blood flows through the aorta as it is pumped around the body by the heart. If you don't have 'beating' or blood flow in the aorta, you have serious trouble. If the aorta gets stretched out and enlarged, that is a problem called aneurysm. ...Read more

The diameter of my abdominal aorta periodically ranges from 28 to 40 mm. What is the reason?

The diameter of my abdominal aorta periodically ranges from 28 to 40 mm. What is the reason?

Aortic measurements: The typical abdominal aorta measures about 20-25 mm and is uniform in diameter along its entire course. Parts of the aorta, however, can enlarge and become an aneurysm. Aortic aneurysms are defined as a segment that is at least 50% larger than the normal segments of the aorta, so typically anything 30 mm and above. You likely have an aortic aneurysm and should consult with a vascular surgeon. ...Read more

If you have 14mm abdominal aorta as a 23 yo, you will have thinner walls than if you had 2cm healthy aorta and so a weaker aorta. More prone to burst?

If you have 14mm abdominal aorta as a 23 yo, you will have thinner walls than if you had 2cm healthy aorta and so a weaker aorta. More prone to burst?

Just the opposite: Aortic aneurysms have a higher risk of rupture with increasing diameter. Generally they are treated expectantly with observation and antihypertensives if necessary until they become symptomatic (with pain or showering emboli distally), or enlarge greater than 5 cm. The two methods of fixing them are with a traditional operation or more recently, stent placement. ...Read more

If X-ray shows abdominal aorta (enlarged) does that mean plaque problem?

It might: Typically an enlarged aorta is due to an anuerysm. The anueysm may or may not contain cholesterol plaque. Aortic aneurysms are repaired once they reach a certain size due to the risk of rupture. People with aortic anuerysms should follow up routinely with a vascular specialist for ongoing management of the condition (cardiologist or vascular surgeon). ...Read more

Is an abdominal aorta of 14 mm in diameter really small? I read that 2, 5 CM was normal?

Not necessarily.: There is a significant difference is the average size of the female abdominal aorta versus the male aorta. The average size of the female is about 1.8-2.5 cm, and the average size of the male aorta is higher. If the distal vessels, going to the legs are of normal size and caliber, and the patient is female-there is no concern. If male, then a better look at the walls of the aorta, is needed. ...Read more

Because my abdominal aorta is so small (14mm), does it have to stretch much more than a bigger one?

Because my abdominal aorta is so small (14mm), does it have to stretch much more than a bigger one?

Not necessarily: We don't know YOUR size - your aorta may be proportionate to your body surface area. Regardless, if you're perfusing your lower extremities sufficiently (easily determined by measuring the BP in your legs and comparing it to your arms), then the size or "stretch" is irrelevant. ...Read more
