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. ...Read more

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. ...Read more

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

How can you measure aorta size?

How can you measure aorta size?

Ultrasound, but...: The two primary ways we measure the aorta is by ultrasound or ct scanning. Each modality has its pros and cons. While ultrasound is the preferred screening and first-line method of aortic imaging, one caveat to keep in mind is that it does tend to overestimate the size of the abdominal aorta and it is not practical for imaging of the thoracic aorta. Ct is more accurate though not cost-effective. ...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
