study guide test 3 Flashcards
- Bypass graft evaluation begins with pt hx and surgical record with type of graft. T OR F
True
- A fem to fem graft is also referred to as a jump graft T/F
True
- Purpose of this procedure is to prevent access for dialysis for Hemodialysis fistula and graft? t/f
True
- Radial artery to cephalic v fistula is most common
true
- Goal of physiological testing in lower extremities is to determine if there’s evidence of arterial disease?
True
- Indirect phys. Test methods include BPR, leg pressures, waveform, and exercise stress test t/f
True
- Palp of pulses document from 0-3
True
- Four cuff method is reported to be better at differentiating disease from iliac arterial disease
true
- Systolic pressure in arm are used to calculate AFI, would you used lowest arm pressure of the two
false
- ABI of higher than 1.4 is highly suggested of calcified arterial disease t/f
True
- Blood pressure cult width should no be greater or less than (percent)
20 %
- Characteristic of norm Doppler waveform
Triphasic, dicrotic notch
- What the most important criteria for arterial Doppler imaging
spectral doppler wave form
- Most pt describe clottication as what? Cramping or pain
cramping
- Pt complain of intermittent claudication, ABI to begin with?
.59
- Doppler angle if imagining arteries
60 degrees
- Compression therapy of pseudoanuersym
applying pressure at the neck of the pseudoanuersym
- Plane should you look at artery when you’re doing Doppler?
long/sag
- Profundata artery location in reference to fem artery?
posterior/lateral
- Branches of pop are what
Anterior tibial and tibial peoneal trunk
- Segmental pressure of lower extremity, under or overestimate disease
underestimate
- Toe pressure is norm if it is how many mm of mercury
50 mmHg
- Calf PVR norm have greater waveform why? Sequential changes, hint
sequential changes and cuff artifact
- Ankle pressure that fall after exercise of return to baseline in 5 mins they suggest what kind of disease?
single-segment occlusive disease
- Non diabetic pt, ischemic skin lesion won’t heal if the pressure is below how many mm of mercury
30 mmHg
- When imaging graft, what is your protocol
(might be an except question)
NOT evaluate the velocity decreases, obstruction, or flow channel changes.
- Following procedure use GSF v for arterial conduit
in situ vein bypass
- GSV is removed, upside and sewn back in is what procedure
Reverse vein graft
- Structure used to mechanical how artery open
Stent.. Balloon-deployed stent or self expanding stent
- Less invasive method for AAA
Placing a stent graft through a catheter into the aneurysm
- Complication of stenting:
Leaking, infection, embolization
- Arterial obstruction is common in subclavian artery but uncommon in what vessels
The axillary, brachial, radial, and ulnar arteries less likely to be involved.
- Autoimmune that will affect subclavian a
takayasu and giant cell arteritis
- Bueger’s disease has another name
Thromboangiitis obliterans
- Small emboli that include vessels of hand and digits
Thromboemboli
- Prolong muscle vasospasm brought on by cold exposure can be caused by ulceration n nicotine
Raynaud’s
- Two names for raynaud’s
Primary Raynaud’s(Disease) and Secondary Raynaud’s(Syndrome)
- High incidence of raynodes
70-90% of cases occur in females
- Intermittent pain numb or weakness of arm, what disease are we looking for
Thoracic Outlet Syndrome (TOS)
- PPG, best position for pad on toes
It’s placed on the pad of the Great toe
- What do we do to test for Raynaud’s
Record pre-submersion PVRs or PPGs on symptomatic digits
Submerge hand(s) in ice water for 1-2min (or less if patient cannot tolerate)
Obtain post submersion readings on symptomatic digits
Obtain tracings at 2 or 3 min intervals thereafter
If PVR amplitude returns to baseline levels within 5 min, it’s normal
If waveform continues to be low after 10min or longer, it confirms Raynaud’s
- Test for radial hand perfusion
The Allen test
- One type of graft that is inpenetratable?
Vecta
- Standard recovery time for standard cold immersion…? 2 or 5 mins
5 minutes
- Arterial leg anatomy
p. 171
- arterial arm anatomy
p. 257
- Different situations: norm, ischemia, ao fem,multilevel disease
