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

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

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

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

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

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

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

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

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

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

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

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

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

Can you please explain why coronary and carotid are the first arteries to be affected, not subclavian or others?

Symptoms: Because of the sensitivity of what is being perfused, we notice disease in heart, brain and kidney vessels more than others. Atherosclerosis doesn't necessarily affect them earlier however. ...Read more

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

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

Told total subclavian blockage, & one artery of 4 leading to brain has reversed, and is trying to route this blood to make sure arm has blood flow. Vascular surgeon says do nothing??

Told total subclavian blockage, & one artery of 4 leading to brain has reversed, and is trying to route this blood to make sure arm has blood flow. Vascular surgeon says do nothing??

Would prob agree: Subclavian blockages generally don't lead to a lot of pain. The pain you may experience from blockage would be arm fatigue or muscle discomfort in arm when using it. The reversed blood flow is your body compensating for the blockage. If severe could lead to feeling light headed.
Best to treat with antiplatelet (aspirin) possible staton and reduce risk factors. ...Read more

What does 'diffuse severe attenuation of the left vertebral artery" mean on a neck ct scan with contrast? Could it be cause of previous spontaneous arterial brachial clot or subclavian clot?

What does 'diffuse severe attenuation of the left vertebral artery" mean on a neck ct scan with contrast? Could it be cause of previous spontaneous arterial brachial clot or subclavian clot?

Hard to: Say with certainty without access to the images and report, but most commonly this is simply due to a developmental/congenital anatomic variation whereby one vertebral artery is very small. This would not be the cause of a clot elsewhere. ...Read more
