Question | Answer |
---|---|
anastomosis: | junction of two vessels |
aneurysm: | a localized sac or dilation of an artery formed ata weak point in the vessel wall |
angioplasty: | an invasive procedure that uses a balloon-tippedcatheter to dilate a stenotic area of a blood vessel |
ankle-brachial index (ABI) or ankle-arm index (AAI): | ratioof the ankle systolic pressure to the arm systolic pressure;an objective measurement of arterial disease that providesquantification of the degree of stenosis |
arteriosclerosis: | diffuse process whereby the muscle fibersand the endothelial lining of the walls of small arteriesand arterioles thicken |
atherosclerosis: | inflammatory process involving the accumulationof lipids, calcium, blood components, carbohydrates,and fibrous tissue on the intimal layer of a largeor medium-sized artery |
bruit: | sound produced by turbulent blood flow through anirregular, tortuous, stenotic, or dilated vessel |
dissection: | separation of the weakened elastic andfibromuscular elements in the medial layer of an artery |
duplex ultrasonography: | combines B-mode gray-scaleimaging of tissue, organs, and blood vessels with capabilitiesof estimating velocity changes by use of a pulsedDoppler |
intermittent claudication: | a muscular, cramplike pain inthe extremities consistently reproduced with the samedegree of exercise or activity and relieved by rest |
ischemia: | deficient blood supply |
rest pain: | persistent pain in the foot or digits when thepatient is resting, indicating a severe degree of arterialinsufficiency |
rubor: | reddish blue discoloration of the extremities; indicativeof severe peripheral arterial damage in vessels thatremain dilated and unable to constrict |
stenosis: | narrowing or constriction of a vessel |
