Causes Of Bruit
Doc heard a Bruit In left CAROITED artery. Ultrasound came back complete normal. What is causing the bruit?
Bruit refers to a sound, heard via a stethoscope, of blood when it flows through a narrowed opening. As blood flows through a narrow diameter within a vessel, the velocity of flow increases and also becomes more turbulent. The importance of this sound is that, if your doctor hears it, it can signify underlying atherosclerosis--i.e. Build-up ...Read more
Can past vad - vertebral arterty dissection cause stenosis or a bruit in the carotid artery? Or any other stress to local arteries? What is the path?
Not usually: A bad trauma can cause dissection of vertebral and carotid arteries at the same time but rare. Carotid bruit can indicate a stenosis which is usually atherosclerosis. Fibromuscular dysplasia can cause narrowing. Fmd is usually in women. Fmd can affect the vertebral arteries and the carotid arteries. Fmd can cause dissection in vertebral and carotid arteries. ...Read moreSee 1 more doctor answer
Not usually: A bruit is just the sound of turbulent blood flow, like the rapids of a river. These tend to be found at places of narrowing or plaque buildup. The symptoms tend to be related to low perfusion or plaque breaking off. Not all bruits are harmful; not all narrowing has bruit. Ultrasound and/or ct/mri can help diagnose. ...Read moreSee 1 more doctor answer
Yes: A bruit is basically the turbulence in an artery caused by a blockage. A good analogy would be when a nice wide silently flowing river narrows and gets very turbulent and loud like a rapid. If the humming you hear is pulsatile / cyclical then it could very well be coming from your carotid arteries. A simple carotid ultrasound can help evaluate the arteries to rule out any narrowing. ...Read moreSee 1 more doctor answer
Misunderstanding: A cardiac murmur is a noise that can be detected when the examiner listens with his/her ears - usually through a stethoscope. It's caused by turbulence of blood flow through a valve or a chamber. When a murmur is detected outside the heart, it's called a "bruit". Thus, there is no such thing as a "cardiac bruit". Some bruits are quite normal - for instance, they're often found in pregnancy. ...Read moreSee 2 more doctor answers
Can a bruit in corotid artery be caused by a psychosomatic response, for example due to stress or anxiety?
Medical management: A "bruit" is noise transmitted from turbulent flow. The most common cause of a bruit is atherosclerosis either in the chest arteries or neck arteries. A fair number of healthy people can have a benign bruit due to turbulent flow. A few tests - carotid ultrasound, ankle brachial index can establish if there is atherosclerosis. If you do have atherosclerosis, medical management, no smoking is key. ...Read more
