Flashcards in Arterial Test Deck (50)
A bypass graft evaluation begins with patient history, surgical record, and type of graft. (T/F)
A femoral-femoral graft is also called a jump graft. (T/F)
The purpose of this procedure is done to provide access for dialysis. (T/F)
The superficial cephalic and basilic veins are evaluated (mapping) as part of a preop workup for hemodialysis access placement. pg. 209
Radial artery to cephalic vein fistula is the most common. (T/F)
The goal of lower extremity arterial testing is to evaluate for arterial disease. (T/F)
Indirect physiological testing includes: PVR, segmental pressures, waveform analysis, and exercise stress. (T/F)
Palpations of pulses with a rating system from 0-3. (T/F)
Four cuff method is better at differentiating inflow from femoral artery diease. (T/F)
Systolic pressure in the arm is used to calculate the ABI, which pressure (lower or higher) of the brachials will you use to calculate ABI?
An ABI of 1.4 is highly suggestive of calcified arterial disease. (T/F)
Blood pressure cuffs should have a width how much greater compared to the limbs?
What is the important criteria during an imaging arterial system?
Early diastolic reverse flow
What plane should you do arterial imaging in?
What angle is good for a Doppler study?
How long does it take to compress a psuedoaneursym?
20-30 min (30-60min)
What would the arm pressures be if there is evidence of a subclavian steal?
20 mmHg difference
If a patient is complaining of an intermittent claudication, their ABI should be ___.
What does claudication feel like?
pain and discomfort while walking
Where does the SFA lie in reference to the profunda?
Anterior to the profunda
What are the branches off the popliteal artery?
Do segmental pressures typically overestimate or underestimate?
A normal toe pressure is ___ mmHg or greater.
For what reason do PVR's usually have greater amplitudes than the thigh?
What disease is suggested when ankle pressures fall after exercise and return back to normal in 5 minutes?
single segment occlusive disease
What might the ankle systolic pressure be if the patient has ischemic lesions?
50mmHg or less
What is the protocol for a graft?
Prox flow –native vessel
DST flow –native vessel
What type of graft is in-situ?
uses the GSV and all the vein valves are removed then the proximal and distal ends are connected to the artery.
-fem-pop and sometimes fem-tibial
What is a reverse vein graft?
the GSV is removed and turned upside down without removal of valves then sewn back in.
A follow up surveillance of grafts allow the surgeon early detection of ___.
aneurysms, psudoaneurysms, perigraft abscess, defects, stenosis, occlusion
