TERMS Flashcards
the strong outer covering of the arterial vessle, composed of CT as well as collagen and elastic fibers. stretching occurs from increased pressure
tunica adventitia
the middle layer of the arterial vessel composed of SM and elastic fibers. The layer is thicker in the arteries than the veins
tunica media
the inner layer of the arterial vessel composed of an elastic membrane lining and smooth endothelium covered by elastic tissues
tunica intima
abnormal dilatation of an artery
aneurysms
paroxysmal bilateral digital arterial vasospasm, related to sympathetic response either primary or secondary
raynauds
symmetric, persistent cyanosis of distal extremities (feet/hands/digits)
acrocyanosis
etiology unk. sympathetic mediated constriction of arterioles with concurrent atony of the venioles
livedo reticularis
plaque builds up in the arteries and results in narrowing of the artery
atherosclerosis
hardening of the arteries
arteriosclerosis
inflammatory condition of medium and small sized arteries and veins leading to thrombotic occlusion and potentially necrosis of acral segments of extremities
thromboangiitis obliterans (buergers disease)
affects small arteries of the foot and may still have DP and PT pulses?
blue toe syndrome
encompasses the vascular diseases caused by atherosclerosis and thromboembolic pathophysiologic processes that alter normal structure
PAD
functional impairment that happens during ambulation and relieved by rest
ABI: 0.7
intermittent claudication
pain in the forefoot, extends farther up the leg, mainly associated with positional elevation
ABI: 0.4-0.5
rest pain
condition where ischemic pain, non healing ulcers or tissue loss in one or both legs remains for 2 or more weeks, and the condition is objectively attributable to proven arterial occlussive disease
critical limb ischemia
