Arterial Pathology, Patient History, and Physical Exam Flashcards
(71 cards)
most common arterial pathology
atherosclerosis obliterans (ASO)
what is ASO?
thickening, hardening, and loss of elasticity of the arterial wall with deposition of plaque (between intima and media)
patients with symptomatic ASO will likely have disease in multiple locations such as (4)
carotid bifurcation
aorta iliac system
CFA bifurcation
distal SFA
treatment of ASO (3)
- control factors - smoking, exercise, weight, diet
- pharmacological - control BP, diabetes, hyperlipidemia
- surgical/intervetional
most common symptom of peripheral arterial disease (PAD)
claudication
most feared consequence of PAD
severe limb ischemia and amputation
thrombosis gradual progression is better tolerated through (2)
collateralization
compensatory mechanisms
acute occlusion/thrombosis can occur in less severe lesions, resulting in ___
sudden occlusion with minimal collateralization
most frequent cause of embolism
thrombus or plaque
___ may be a medical emergency if collateralization and compensatory mechanisms are insufficient to sustain tissue or organ function
acute arterial occlusion
6 P’s associated with acute arterial occlusion
- pain
- pallor
- pulselessness
- paresthesia
- paralysis
- polar/poikiloderma
aneurysm is a dilatation of an artery ___ times the diameter of the adjacent artery
1 ½ times
aneurysms are classified by (3)
morphology
location
type
most common location for aneurysms
infrarenal abdominal aorta
other locations for possible aneurysms (4)
thoracic aorta
Pop A
CFA
renal artery
~50% of patients with a ___ aneurysm will have an aortic aneurysm
popliteal
3 causes of aneurysms
atherosclerotic disease - most common
congenital
infection (mycotic)
most frequent aneurysm complication
AAA =
peripheral arterial aneurysm =
AAA - rupture
peripheral arterial aneurysm - embolization
non-atherosclerotic diseases (5)
- arterial dissection
- dissecting aneurysm
- coarction of the aorta
- fibromuscular dysplasia
- arteritis
arterial dissection is ___
an intimal wall tear that fills with blood
arterial dissection divides the vessel into
true and false lumen with different flow characteristics
arterial dissections often occur in the ___
thoracic aorta
3 causes of arterial dissection
spontaneous
trauma
hypertension
4 complications of arterial dissection
stenosis
occlusion
thrombosis
death
