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
Yes: The recurrence rates after endarterectomy depend in a number of factors such as smoking, patch use for angioplasty and on going problems with managing the risk factors of peripheral vascular disease. Women may also be more likely to have recurrent disease. ...Read moreSee 2 more doctor answers
Chronic radial artery occlusion. Pain in hand arterial doppler shows interosseos artery enlarged. Ulnar artery responsbile for profusion. Advice?
Depends: When blood flow is sufficiently reduced by a greater than 70% blockage of an artery or arteries, to the point of permanent damage or weaknening of the heart muscle, or when a plaque ruptures and a blood clot repeatedly forms with resulting blockage of blood flow, then an artery needs to be stented, or bypassed. ...Read more
Middle LAD & circumflex artery are 100% blocked. Blockages, while severe, short in length.Both arteries receive collateral. Can angioplasty/stent help?
Carotid surgery: Carotid surgery should be done when risk of not doing so higher. Stroke risk lowest for asymptomatic stenosis, higher in those with TIAs and yet higher with prior stroke. Risk of MI can be higher than stroke risk. Slight risk of bleeding, real but low risk cranial nerve injury, low risk of surgically significant carotid renarrowing. Generally stroke risk lower for surgery, MI risk lower for stent. ...Read moreSee 1 more doctor answer
2 things: Carotid artery stenosis means narrowing of the artery. Stroke is death or damage to brain due to circulatory issues. Many strokes (approx 1/3rd) are due to carotid artery disease. Although frequently connected, they are not the same. Many strokes occur without carotid stenosis. Many carotids are completely occluded (slowly) without resultant strokes. ...Read moreSee 3 more doctor answers
Elderly Hypertensive: Carotid stenosis usually occurs secondary to longstanding atherosclerosis. Risk factors include high blood pressure, diabetes, and coronary artery disease. It takes time for atherosclerotic plaques to develop, so most patients with carotid artery stenosis are older adults. ...Read moreSee 1 more doctor answer
The third artery: Normally the main coronary blood vessel has two branches--the left anterior descending artery and left circumflex, but some people have a third branch termed intermediate artery or ramus-coronary artery--see picture. The incidence is some where between 10-30%. This can cause some confusion in ekg interpretation if this vessel is blocked/causing a heart attack. Consult doc. Good luck. ...Read moreSee 1 more doctor answer
Basilar artery: Basilar artery is formed by the confluence of the vertebral arteries. Vertebral arteries are branches off the subclavian arteries. They supply the posterior aspect of brain and flow into the circle of willis. Vertebral occlusions can occur due to atherosclerotic disease and dissection from trauma. ...Read more
Artery blockage: Carotid artery stenosis means that the carotid arteries have blockage, usually in the form of atherosclerosis. This can cause stroke. The more severe the blockage, the greater the risk in the absence of neurological symptoms, most cases can be handled with medicine and close periodic follow up by a vascular surgeon. However, if the blockage is more than 80%, surgery will reduce the stroke risk. ...Read more
Have relatively short 100% blockage in mid LAD &100% posterolateral branch of circumflex artery (both relatively small targets).Will stent help or ris?
stent: There are technical factors in deciding whether stenting is possible and physiologic predictions of whether successful stenting will yield benefit. Your doctors including interventional cardiologist are best to advise you regarding your specific situation. ...Read moreSee 1 more doctor answer
MRI vertebrobasilar hypoplasia right side theres robust flow void anastomosing the basilar artery w cavernous portion of internal carotid artery/mean?
Normal variant: The arteries at the base of the brain can course in several different patterns but ultimately get the job done, that is, supply brain tissue. Your pattern is like your fingerprint. Some more unusual patterns have an increased association with aneurysms, but this would have likely been described if present and vertebro basilar hypoplasia, as in the picture, is pretty common. ...Read more
