Vascular 19 & 20 TEST QUESTIONS Flashcards
Preoperative information important to surgeon planning to use saphenous vein, include all of the following except
How many valves
How often is the GSV a single dominant trunk through the thigh
60%
What makes up the saphenous compartment
saphenous fascia superficially, muscular fascia deeply
Tributaries of the greater saphenous create closed loops within the thigh can create
difficulties for surgeons to pass instruments through
Correct name for posterior arch vein
posterior accessory great saphenous vein
What is the most common source of any fistula formed when you use GSV for in situ bypass
perforators
What are the cranial extensions of the SSV and what all can it terminate into
popliteal v, popliteal fossa, femoral vein, inferior gluteal v and can communicate with the GSV
Intersaphenous vein connects
GSV & SSV
What veins join together to create the axillary vein
basilic and brachial
What all do you do to maximize the resolution in the near field
higher frequency, optimize transmit power and focal zones
What part of venous anatomy does the term “egyptian eye” refer to
the greater saphenous within the saphenous compartment
Which statement concerning venous thrombosis in the GSV is incorrect
pulsatile waveform
Proper preoperative vein mapping can result in all but which one
increase in operative room time
While performing venous mapping using a transverse view, the GSV appears eliptical, what is most likely the cause
too much pressure
T/F. Recanalization is to tie up or close something off
false, that is ligation
T/F. Veins that connect the superficial veins to the deep veins are known as tributaries
False, perforators
T/F. The process of restoring flow is called ligation
False, recanalization
T/F. Varacosities are dilated, tortuous superficial veins
true
T/F/ In situ means within the body
true
During an ultrasound examination, saphenous vein normal backflow before a valve closure usually lasts how long
<500ms
During an ultrasound examination, femoral vein normal backflow before a valve closure usually lasts how long
<1000ms
What is the tributary landmark for thermal ablation treatment
superficial epigastric vein
The saphenofemoral junction is the confluence of which of the two vessels
greater saphenous comes into common femoral
Which statement is not true about the anterior accessory SV
does not coast posterior
What are true of venous valves
leaflets can be seen on b mode, leaflets point in the direction of normal venous drainage, open with muscular contraction and close with relaxation
Treatment for superficial venous disease (4)
stripping/ligation, endovenous thermal ablation, chemical ablation/scierotherapy, phlebectomy (microincision)
Which statement correctly describes spider veins
telangiectasias
Incompetent venous valves allow what
abnormal retrograde flow
Chronic venous valvular insufficiency is an incomplete term because
it fails to differentiate between valvular and obstructive disease
Which of the following statements concerning reverse venous flow is correct
it can cause venous filling
Which of the following statements is incorrect for normal venous spectral doppler
insufficiency with valsalva
Pathologic findings of CVI include all of these
reflux/reverse venous flow, chronic venous obstruction, a pathological combination
An abnormal venous flow pattern is which one
retrograde flow following compressions
Which of the following visual signs is not a symptom of CVI
radiating pain in the posterior aspect of the thigh
Which of the following diagnostic tests is the most useful for definitive diagnosis
ultrasound
Color doppler is used to aid in venous ultrasound suspected CVI by showing what
respiratory phasicity, augmentations with maneuvers, flow direction, flow in small channels, retrograde flow
Venous photoplethysmography uses
infrared light
Fibrous strands within a lumen is most commonly associated with
chronic vein obstruction
T/F. The valve diameter of reticular veins is around <3mm
true
