claudication
pain in the muscle during exercise that subsides with rest; due to inadequate blood supply
ischemic rest pain
more severe symptoms
... [Show More] of diminished blood flow; occur when limb not dependent; BP decreased (sleeping)
acute arterial occlusion
A sudden blockage of arterial blood flow that occurs because of a thrombus, embolus, tumor, direct trauma to an artery.
Symptoms include 6Ps : pallor, pain, pulselessness, paresthesia, paralysis, and polar
Primary Raynauds
Less severe
Ischemia due to digital arterial spasm
Common in young women
May be hereditary, bilateral; hx of symptoms for 2 years w/o progression/ evidence of cause
Benign condition with excellent prognosis
Secondary Raynauds
Worst form
Also known as obstructive raynauds syndrome
Normal vasoconstriction responses of arterioles superimposed on a fixed artery obstruction.
Ischemia constantly present**
May be the first manifestation of Buergers disease.
Buerger's disease
Occurs in men < 40years, associated with heavy smoking, patients present with occlusions of distal arteries = rest pain & ischemic ulcers
pallor
result of deficient blood supply; skin pale.
Rubor
suggests dilated vessels or vessels dilated secondary to reactive hyperemia; skin is reddened
Cyanosis
blue discoloration of the skin caused by a lack of adequate oxygen in the blood
Arterial Lesions/Ulcers
Ulcerations located: tibial area,foot, toes
Deep and more regular shaped
Quite painful as compared to venous ulcers
Can lead to gangrene: death of tissue due to deficient or absent blood supply
capillary filling
An increase in what time can denotes decreased arterial perfusion
what type of elevation/dependency changes occur with arterial disease?
Cadaveric pallor (white) during elevation
Ruborous red discoloration with dependency (dependent rubor)
what pulses can be palpable in body?
Aorta, femoral, popliteal, DPA, PTA
NOT your Peroneal artery!!!
A fistula, post-stenotic turbulence, or a patent dialysis access site
A palpable thrill or vibrations over a pulse can indicate what?
Coarctation of Aorta
1.Congenital anomaly; congenital narrowing or stricture of thoracic aorta
2.Clinical findings: HTN due to ↓Kidney perfusion, manifests as LE ischemia (↓ pulses and/or segmental pressures)
Arteritis
1.Affects the tibial and peroneal arteries, as well as more distal arterioles and nutrient vessels.
2.Inflammation of arterial wall leads to thrombosis of vessel [Show Less]
