76. Peripheral vascular disease Flashcards
8 basic pathologies
- Atherosclerosis
- Aneurysms
- Emboli
- Thrombosis
- Inflammation
- Trauma
- Vasospasms
- AV fistulae
5 Ps of arterial occlusion
Pain Pallor Pulseless Parathesia Paralysis
main management different for emboli vs thombus
- emboli
- fogarty cath - Thrombus
- limb threatening - cath
- otherwise medical
2 types of pain in artertial insufficiency
- pain at rest
- worse with elevation, better with standing - intermittent claudication
Bueger sign
pallor on elevation
rubor on dependency
Grading of ABI
Should be 90%
o Mild 70-90
o Mod 50-70
o Severe < 50
Test for radial artery
Allen test
5 ways to determine if emboli vs thrombus
- identifiable source?
- Hx of claudication
- other limb findings consistent with occlusive disease
- demarcation of ischemia
- arteriography
Skin findings ofter associated with inflammatory cause
o Palpable purura
o Macules
o Papules
o Vesicles
- Non invasive mgmt
- heparin
2. low dose fibrinolytics
what is Arteriosclerosis obliterans
presentation of chronic atherosclerosis
- venous ulcers
- skin chnages
what is Buerger’s disease (Thromboangitis Obliterans)
- Idiopathic inflammatory occlusive disorder of small and medium vessel of hands and feet
- Men, 20-40, smokers
- May have associated venous thrombosis
5 criteria to Dx Buerger’s disease (Thromboangitis Obliterans)
o Smoking o Before 50yo o Infrapopliteal arterial occlusion o Upper limb involvement or phlebitis migrans o No other atherosclerotic risk factors
mgmt of Buerger’s disease (Thromboangitis Obliterans)
stop smoking
what is Atheroembolism (blue toes)
Microemboli
o Cholesterol, Ca, hemorrhagic debris
MGMT of Atheroembolism (blue toes)
- Find and remove proximal source
- Angio is most accurate method
- Look for aortic aneurysm
- Stomatic lesions of arteries
Most common locations of aneurysms
popliteal
- upper extremity rare
MGMT of aneurysms
Asymptomatic
o Elective surgical excision
Life threatening
o Cath removal
2 visceral locations of aneurysms
- splenic
2. hepatic
4 main types of infected aneurysms
- Mycotic
- infections af atherosclerotic vessels
- infection of existing aneurysm
- Post traaumatic false aneurysm
5 Dx criteria needed for raynauds
Precipitated by cold or emotion Bilateral Gangrene absent No disease that may have Sx the same At least 2 years
3 causes of raynaud phenomena
- SLE
- SCleroderma
- RA
3 types of throacic outlet syndromes
1. Arterial Rare but most serious 2. Venous Men 20-35 3. Nerve Sx begn 20-50 yo More women
location of outlet syndrome
where crosses the 1st rib
4 anatomic abnormalities that can cause
1. Cervical rib Complete 2. Scalene muscle syndrome 3. Subclavius muscle hypertrophy 4. Hyperabduction syndrome Only when arms hyper abducted
Test of thoracic outlet syndrome
Elevated arm stress test (EAST) most reliable
Arms abducted to 90, elbows flexed to 90
Open and close fists slowly for 3 minutes
Describe Sx
Early heaviness, fatigue and pain
o Look at hands for changes in skin color
o Test triceps muscle strength (c7)
