Vascular disorders & peripheral circulation Flashcards
anastomosis
junction of two vessels
aneurysm
a localized sac or dilation of an artery formed at a weak point in the vessel wall
angioplasty
an invasive procedure that uses a balloon-tipped catheter to dilate a stenotic area of a blood vessel
ankle-brachial index (ABI)
ratio of the ankle systolic pressure to the brachial systolic pressure; an objective measurement of arterial disease that provides quantification of the degree of stenosis
arteriosclerosis
diffuse process whereby the muscle fibers and the endothelial lining of the walls of small arteries and arterioles thicken
atherectomy
an invasive procedure that uses a cutting device or laser to remove or reduce plaque in an artery
atherosclerosis
inflammatory process involving the accumulation of lipids, calcium, blood components, carbohydrates, and fibrous tissue on the intimal layer of a large or medium-sized artery
bruit
sound produced by turbulent blood flow through an irregular, tortuous, stenotic, or dilated vessel
dissection
separation of the weakened elastic and fibromuscular elements in the medial layer of an artery
duplex ultrasonography
combines B-mode grayscale imaging of tissue, organs, and blood vessels with capabilities of estimating velocity changes by the use of a pulsed Doppler
intermittent claudication
a muscular, cramp-like pain or fatigue in the extremities consistently reproduced with the same degree of exercise or activity and relieved by rest
ischemia
deficient blood supply
rest pain
persistent pain in the foot or digits when the patient is resting, indicating a severe degree of arterial insufficiency
rubor
reddish-blue discoloration of the extremities; indicative of severe peripheral arterial damage in vessels that remain dilated and unable to constrict
stenosis
narrowing or construction of a vessel
