How Much Artery Blockage Causes Pvd Pain
Everyone's different: The pain of pad is from tissue (muscles, skin, nerves, etc) not getting enough blood. An elite athlete might have symptoms from a single 50% plaque. A sedentary person might not notice a complete blockage or multiple partial blockages. Rest pain is usually from severe plaques at multiple levels. In general, the body compensates for artery plaques for a long time before pain occurs. ...Read moreSee 2 more doctor answers
Arteries are a type of blood vessels. We can divide blood vessels into 2 categories. Arteries are high pressure vessels which deliver (red) oxygen + blood out into the body. Veins on the other hand or low pressure vessels which return (dark) oxygent - blood from the body ...Read more
90%: Is the usual amount of blockage that produces "claudication." it varies quite a bit, though; some people don't notice anything until they have 100% blockage, others start to notice problems at 50%. The more you ask of your legs, the earlier you'll notice it. ...Read more

How much blockage in artery or arteries can cause a heart attack. Also does blockage come from plaque and clot.
Blockage is 100%: to suffer an injury the artery must get closed off for a period of time. Talks about percent stenosis (narrowing) reflect how much of the native artery remains open for flow, that number also gives an estimate about how possible it would be for a small clot to come along and plug up that vessel. The usual way the "door slams shut" is when a clot floats in and finishes making a blockage. ...Read more
Blocked artery?: Can't make sense of this. Blockage of an artery can cause pain in the distribution of that artery, but there is no artery common to the fingers AND the knee calf except the aorta - blockage there would be catastrophic. Acute blockage causes ischemia (sudden pain as tissue dies) and chronic blockage produces pain (claudication) which increases with activity. ...Read more
Could it happen that a fall causes a plaque build up in an artery to break off and cause a complete blockage?
See a retina special: Yes. Lack of blood flow due to a retinal artery occlusion can cause severe loss of vision from damage to the retina. A central retinal artery occlusion is worse than a branch retinal artery occlusion. There are no good treatments, but a systemic workup looking for an embolic source is required (carotid ultrasound, echocardiogram). A rarer cause is giant cell arteritis. ...Read moreSee 2 more doctor answers
