Doctor insights on:
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
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
Just need to understand one last thing then ill be gone: my unusually small abdominal aorta 14mm)must stretch more than a normal and it cant be good?

How flexible is the aorta? If I would hold it in my hand how long would I be able to stretch it from side to side before it rupture? Any theory?
Good question: You could go to a butcher and buy a pig aorta and give it a try. There may have been research in this area, look up aortic compliance ...Read more
The smaller the aorta the less it has to stretch to accommodate the pressure thereby more wall stress? Talking about healthy aorta not aneurysm.

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
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
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

The main artery: 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, and inherited risk factors. ...Read more
Surgery sometimes: That would depend on where is the tear and how much it compromises flow to vital organs. If the tear is within the first few inches of the aorta taking off from the heart, emergent surgery is needed. If the tear is further downstream and does not compromise flow to vital organs then it may be treated with medications for pain/high blood pressure and watchful waiting. ...Read more

Not normal: It is not normal to have a hole in the aorta. If a hole is present, it would lead to internal bleeding. Occasionally, abnormal connections between aorta and other structures or blood vessels could be seen which may be contained and/or tolerated. Further detail is needed to answer this question. ...Read more
