The smaller aorta the more it has to stretch to accomodate the pressure? Thereby more wall stress? Need to understand my smaller aorta (14mm) better!

RUTheJollyGreenGiant: No, actually it's the other way around. The bigger it gets the less pressure is necessary to stretch it further. It's called the Law of LaPlace (the guy who figured it out-he reduced it to a mathematical formula).It's a bit more complicated than that, having to do with tissue elasticity, your size, etc. As for your aorta, don't worry too much, as long as you are otherwise healthy and not 8 ft tall.

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

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.

Can 5 weeks of pulmonary hypertension (as well as a few other diagnoses) lead to moderate anoxic brain injury? A patient in his early 50's receives diagnosis of mssa- causing pulmonary hypertension, chf, aortic valve regurgitation, a stretched mitral valv

Can 5 weeks of pulmonary hypertension (as well as a few other diagnoses) lead to moderate anoxic brain injury? A patient in his early 50's receives diagnosis of mssa- causing pulmonary hypertension, chf, aortic valve regurgitation, a stretched mitral valv

Endocarditis: Anoxic brain injury can occur after cardiac arrest. The heart disease you mention could lead to cardiac arrest but you did not mention this in your history. I am concerned about endocarditis, infection of the heart valve, with history of mssa bacteremia. Read more

What is a herniated aorta?

What is a herniated aorta?

No such thing: A hernia is an abnormal protrusion of an organ through a defect -- this really can't happen with the aorta. An enlarged aorta may (incorrectly) be called a "hernia", but more appropriately that would be ectasia or an aneurysm. Read more

What is slight unfolding of aorta?

What is slight unfolding of aorta?

Xray: This is a chest xray appearance of a widening of the normal aortic arch curve in the superior thorax. It does not necessarily have pathologic import though it is often seen in older patients and those with hypertension and atherosclerotic disease. Read more

What does a pinched aorta feel like?

Doesn't happen: Aortas don't get pinched. They can become aneurysmal, rupture, leak, become stenotic (develop "blockage"), tear, become infected, inflamed - but not pinched. Read more

What is the normal psi of your aorta?

What is the normal psi of your aorta?

2-3.5 PSI: Pressure in the aorta is measured in mm of mercury, or mmhg. To convert to psi, divide normal aortic pressure of 100-180 mmhg by 10 to get cmhg, then use any simple conversion chart or app. It works out to 1.9 to 3.5 psi. Curious as to why you would want to know this though? Read more

What does uncoiling of the aorta mean?

Aorta: The term uncoiling of the aorta refers to an appearance on the chest xray which looks like the aorta has untwisted and elongated as if it is an unwound coil of a spring. Read more

What is atheroselerotic disease of aorta?

Cholesterol plaques: Atherosclerosis literally means "hardening of the arteries" which is caused by plaques or buildup of cholesterol along with immune cells and scar tissue inside the walls of blood vessels. This can occur in any blood vessel in the body, including the aorta, which is the large artery that delivers blood out to the body from the heart. Read more

What does atheromatous aorta mean medically?

Cholesterol plaque: It means the aorta has some cholesterol plaques on it. When noted on a x-ray or ct scan, this typically means that some calcified plaques are present on the films. Usually this is managed through cholesterol medication. Read more

Could I survive a knife stab through the aorta?

Could I survive a knife stab through the aorta?

Through the: Actual aorta - very unlikely. If you are having
thoughts about killing yourself, get seen at the nearest emergency room now. Have a friend or relative drive you or call 911 for emergency services for transport. You can call the national suicide hotlines 24/7 at 1-800-suicide (1-800-784-2433) or 1-800-273 – talk (1-800-273-8255) for support. Read more

Please tell me what does atheromatous aorta mean?

ATHEROMATOUS AORTA: This means there are atheromatous changes seen on an imaging study which shows these changes in the aorta. It means the patient has atherosclerotic vascular disease. Read more
