study guide 2 Flashcards
Jugular vein can be compressed from transducer pressure from skin. T/F
True
Purpse of superficial vein mapping to determine the veins ability to bypass conduit T/F
true
Purpose of venous reflux testing is see if venous is competent T/F
(if it is incompetent, its true if its competent, its false)
True(afl)
Diffcult to compress during duplex imaging?
Subclavian
Varicose triad, three factors
venous stasis, Hypercoagulability, vein wall injury
Longest vein in the body
Greater saphenous
Most important critical for R/O DVT
Coaptation (vein responce to transducer compression on the skin)
Vein reflux ,time when identifing
Over 1 sec
Superficial fem v, is it deep, superficial
Deep
Vein duplex imaging, it is best to used what plane
Sagittal, long
Risk factors for DVT
Post operative state, previous DVT, cancer malignancy, trauma, pregnancy, high dose estrogen, immobility (long car or plane travels), thrombophilia, bed rest> 4 days
Venous valves are seen in which veins and not in which veins?
not soleal sinuses (afl)
CFV lies in which canal?
From the confluence of the deep femoral vein extends 2-3 cm to the groin crease (scarpa’s canal afl)
Basilic vein is what, deep/ superficial
Superficial
Perforating from GSV in thigh is what, cocketts/ bods/ dods
Dodds
Adequate pressure is applied to compress a vein when
the companion artery is deformed
Pulsatile signal is normal in which veins
Subclavian because closer to heart
Compression technique is not used for what?
Floating thrombosis
What is the lethal complication of acute DVT
pulmonary embolism
Signs and symptoms of DVT
persistent leg pain with acute onset
persistent leg swelling
calf pain/tenderness(not baker cyst afl)
In the presents of incompetent valves, distal aug produces, no blood flow/antegrade
retrograde flow
Identify what is a deep vein
Upper: jugular, brachiocephalic/ innominate, subclavian, axillary, brachial, radial, ulnar
lower: external/internal iliacs, femoral, popliteal, anterior/posterior tibial, peroneal, gastroc
(not external juggulal afl)
Most important diagnostic is how the vein reacts to transducer
The vein should collapse if there is no blood clot
Pop vein and what position it lies with pop artery
Pop vein on top ( anterior to artery afl)
Chronic complication occurs after DVT
valuular incompetence (afl )
Upper extremity DVT is common in patients with
PICS, Catheaters
Which of the following terms describe the anatomical variant in lower extremity
bifid femoral vein
Symptoms related to venous imaging
leg pain leg swelling calf pain tenderness history of dvt sob (afl)
Why is Doppler angle correction not necessary in venous imaging
velocity calculation is not necessary(afl0
In what position should you preform venous imaging
supine, knees slightly flexed, legs below heart level
Doppler exam reveals above baseline flow, this demonstrates what
venous reflex(afl)
