It may occur as the result of carotid artery stenosis [1] (though some disagree); [2] however, most carotid bruits, particularly those found in younger or asymptomatic patients, are not related to any disease and are termed "innocent carotid bruits". [3] Many carotid bruits are discovered incidentally in an otherwise asymptomatic patient. The ...
On the right side it starts from the brachiocephalic artery (a branch of the aorta), and on the left side the artery comes directly off the aortic arch. At the throat it forks into the internal carotid artery and the external carotid artery. The internal carotid artery supplies the brain, and the
This is a shortened version of the seventh chapter of the ICD-9: Diseases of the Circulatory System. It covers ICD codes 259 to 282. The full chapter can be found on pages 215 to 258 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
Bruit, also called vascular murmur, [3] is the abnormal sound generated by turbulent flow of blood in an artery due to either an area of partial obstruction or a localized high rate of blood flow through an unobstructed artery.
A right bundle branch block (RBBB) is a heart block in the right bundle branch of the electrical conduction system. [1] During a right bundle branch block, the right ventricle is not directly activated by impulses traveling through the right bundle branch. However, the left bundle branch still normally activates the left ventricle.
Venous hum is a benign auscultatory phenomenon caused by the normal flow of blood through the jugular veins. [1] At rest, 20% of cardiac output flows to the brain via the internal carotid and vertebral arteries; this drains via the internal jugular veins.
IVCD can be caused by abnormalities in the structures of bundle of His, Purkinje fibers or ventricular myocardium. [ 5 ] [ 6 ] Nonspecific intraventricular conduction delay (NICD) is a delay with widened QRS complex but without a specific intraventricular block present.
Seen in an MRI as two individual arteries at this hairpin, a carotid artery dolichoectasia can progress so far as to produce a second hairpin turn and appear as three individual arteries on an MRI. In the case of a dolichoectasia of the Internal Carotid Artery (ICD), the pathogenesis is primarily related to compression of the optic nerves at ...
