If an accident victim had a severed left subclavian artery, which pulse (neck or wrist) would be most affected? Why?

If an accident victim had a severed left subclavian artery, which pulse (neck or wrist) would be most affected? Why?

The wrist.: Blood flow in arteries is away from the heart. The subclavian artery goes into the arm and is past where the vessels to the neck are located. If it is cut then flow to the forearm and wrist may be less. ...Read more

Artery (Definition)

Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more

Anantomy test?: If you hop on the internet you can find the SCA anatomy and follow the SCA to the brachial and then the radial and ulnar and you'll have your answer. But in reality, anyone who severs that artery has a good chance of bleeding out and would probably die if not treated immediately. ..., and in that case ALL of your arteries pulses would be 'affected' ...Read more

I just had an endoscopy and a dialation of my esophagus and an aberrant subclavian artery that was pushing on my esophagus, will I need it done again?

I just had an endoscopy and a dialation of my esophagus and an aberrant subclavian artery that was pushing on my esophagus, will I need it done again?

Not for that reason: As long as your endoscopy showed nothing else going on, you probably do not need another one. However, you need to find out from your doctor whether or not something needs to be done about the aberrant subclavian artery. ...Read more

Subclavian artery: Thx for your help! Would the symptoms of a diverticulum in an aberrant subclavian artery include vertigo, pain in chest, shoulder and throat? ANS: Never heard of a diverticulum in an aberrant subclavian artery. Perhaps you mean a diverticulum caused by the artery. Please clarify. Just an aberrant SC artery could cause pain as could an aneurysm. More details please. ...Read more

I've had a chronic cough for four years and I've just found out I have an aberrant right subclavian artery What can I do? Thanks.

Make sure cause: Of your cough may due to diseases that cause is congenital anomaly (born with it), normally right subclavian arises from right side (from innominate)aberrant a arises from left side, crosses behind trachea & esophagus there by forming a 'vascular ring that may choke and cause difficulty in swelling, may cough, if this is the case need to reposition it to right by vascular surgeon ...Read more

What is the significance of aberrant subclavian artery?

May cause symtoms: Aberrant subclavian artery (right) arises directly from aorta crosses behind esophagus, or in front, or front of trachea, may cause difficulty in swallowing, breathing, or even hoarseness due to compression of recurrent laryngeal nerve, is corrected by transecting at aorta & inserting to rt common carotid artery. ...Read more

Male 31, CT scan showing Abberrant right subclavian Artery, is this harmful? Does it need Surgery?

The vast: Majority are asymptomatic and require no treatment. A very small percentage may cause symptoms related to tracheal/esophageal compression. Aberrant right subclavian artery is an anatomic variation in which the right subclavian artery originates farther along the aortic arch than the normal situation. ...Read more

What exactly does it mean to have an anomalous origin to the right subclavian artery, arising from distal aortic arch?

What exactly does it mean to have an anomalous origin to the right subclavian artery, arising from distal aortic arch?

Anatomy: In the picture you see the aortic arch and the 3 vessels coming off. These are the innominate, left carotid and left subclavian. The proximal aorta is coming from your heart and the distal aorta is heading away to your body. Usually the right subclavian would come off the innominate. Yours, probably due to a developmental quirk, comes distal directly off the aorta. ...Read more

An MRI to test for HCM says There is a tortuous descending aorta. There is an aberrant right subclavian artery which courses posterior to the trachea?

An MRI to test for HCM says There is a tortuous descending aorta. There is an aberrant right subclavian artery which courses posterior to the trachea?

MRI answers nothing: The MRI answers nothing about HCM. The descending aorta being tortuous points to a long history of hypertension, smoking, and/or high cholesterol. The right subclavian normally passes in front of (not behind) the windpipe. This anomaly probably doesn't mean much, u were probably born with it. With HCM, you want to get an idea of how narrow the outflow tract (aortic valve) is, which is not given. ...Read more

MRI =Mild" thickening of heart muscle not HOCM. Tortuous descending aorta. Aberrant right subclavian artery which courses posterior to the trachea.??

MRI =Mild" thickening of heart muscle not HOCM. Tortuous descending aorta. Aberrant right subclavian artery which courses posterior to the trachea.??

Mild thickening's OK: See my comment to your previous post regarding the other findings (tortuous aorta, subclavian artery). The mild thickening of the heart muscle is common, and not necessarily from HCM. It could be the effects of long-standing hypertension. Keeping ur BP low with a -pril or a -sartan (Enalapril, Valsartan, etc.) could even reverse the thickening of the heart. Thanks 4 ur question on HealthTap, & GL! ...Read more

Left subclavian athelsclerotic narrowing in artery can this cause dizziness ect. An what can I do for this?

Maybe.: Sometimes, you can develop a condition called "subclavian steal" where the arm steals blood from the brain causing dizziness. Fixing the narrowing (sometimes with a stent) can stop the arm from stealing blood from the brain. See your physician if you would like more information. ...Read more

Vas surg said blocked subclavian L artery. No bp, & barely a pulse. 1 of 4 arteries to brain has reversed flow to try to get blood to L arm? Stroke?

Vas surg said blocked subclavian L artery. No bp, & barely a pulse. 1 of 4 arteries to brain has reversed flow to try to get blood to L arm? Stroke?

Complicated scenario: Subclavian stenosis & coarctation of the aorta can cause this scenario. You may've been born with a condition & it just progressed. In any case, the situation's VERY complex. There's not enough space here to establish your history, go over ALL of your questions/concerns, & figure out a treatment plan that will reduce complications in the future. You're best off using HealthTap Prime. Good Luck! ...Read more

Why do u feel a much stronger pulse in the left side of your chest? Which artery are there? It is not the heart area im taking about...

Where in chest?: Not sure what answer you are looking for here. The heart is located in the Left chest area, so any artery in that area will have a larger sounding pulse with slightly more intensity simply because of the proximity to the beating heart. Best wishes. ...Read more

Should the pressure in the carotid arteries on the right side be roughly the same as on the left side? Right side pulse is weak. What could cause this

Should the pressure in the carotid arteries on the right side be roughly the same as on the left side? Right side pulse is weak. What could cause this

Arteries: Yes, the pressure or strength of the pulsation in each carotid artery should be the same unless there is a blockage reducing the pressure in the one with a weak pulsation. However this would be unusual in your age bracket. If you have further concerns have your physician examine and advise you. ...Read more

Have a lump about size of a pea next to artery on left side of neck where I can feel pulse. Noticed this for about a few days. Cause of concern?

Watch it: Check it every week or so. If it does not double in size, nor becomes painful, you may leave it alone. An occasional enlarged lymph node in the neck is not uncommon. Make sure to take care of your oral health to ensure it not due to something in your mouth. ...Read more
