Peripheral Arterial Disease Flashcards
Lower extremity arterial blockage is most often a result of ____
atherosclerosis
What two atherosclerotic risk factors are most often associated w/ lower extremity occlusive disease?
Smoking
Diabetes
Claudication presents with: (3)
Cramp
Ache
Fatigue
T/F: Calf cramps at rest are suggestive of arterial ischemia.
False. NOT suggestive
Ischemic pain at rest is typically seen ____
distally in foot across the metatarsal heads
Ankle-brachial indices less than 0.4 may be associated w/ ___ (2).
Rest pain
Tissue loss
T/F: Pulse volume recordings are not affected by calcification of vessels, as in diabetics.
True
T/F:Ankle-arm index is not affected by calcification of vessels, as in diabetics.
False
Neurogenic claudication often occurs with ____
Standing alone
NOT true in arterial claudication
T/F: imaging studies are necessary to diagnose arterial occlusive disease.
False. Diagnosis by history, PE, supplemented by arterial pressure studies.
Imaging studies used when determining intervention.
Most important intervention for lower extremity occlusive disease is ____
atherosclerotic risk factor modification
T/F: Claudication is generally benign and the decision to intervene is based on anatomy.
False. Based on degree of impairment of individual.
Most common site of aortic aneurysms
infrarenal aorta
Most common site of peripheral arterial aneurysms
popliteal
What imaging modality is used to screen for aneurysms?
Ultrasound
T/F: Popliteal aneurysms are highly likely to rupture.
False. Almost never rupture
BUT can cause ischemia b/c of thrombosis and embolism
Aortic aneurysms are surgically treated with ___.
prosthetic graft
Peripheral aneurysms are surgically treated with ___.
bypass/ligation
Feasibility of stent graft repair of aneurysms is dependent on ____
suitable anatomy
Clinical presentation of carotid bifurcation disease/carotid occlusive disease include all EXCEPT: A. Dizziness/syncope B. Contralateral extremity C. Lower facial weakness D. Sensory changes E. Aphasia F. Ipsilateral monocular vision loss
A. Almost never dizziness/syncope
Carotid bifurcation disease diagnosed least expensively and least invasively by ____
Duplex scanning
When determining the degree of stenosis on arteriographic studies, ____ should be used as denominator for stenosis determination.
distal internal carotid
T/F: Carotid endarterectomy (CEA) is more effective treatment for symptomatic carotid occlusive disease patients than asymptomatic.
True
T/F: Carotid stenting has 2x the risk of peri-procedural stroke than carotid endarterectomy.
True. Treatment for carotid occlusive disease
