Pt positioning for lower extremities |
Supine or reverse Trendelenburg for venous filling |
|
|
Pt positioning for upper extremities $$ |
Supine or fowlers position 60 degrees upright Pledge position |
|
|
What's the fourth pair of veins in the calf that are paired with an artery? $$$ |
The gastrocnemius veins |
|
|
Soleal veins $$ |
Non paired thick walled vein reservoirs within the soleal muscle. No valves, drain into deep system |
|
|
Why are acutely thrombosed veins dilated? |
Veins are elastic. As the lumen is obstructed , pressure increases, and veins dilate to compensate |
|
|
Normal flow is spontaneous, continuous flow may be an indication of. . .#$$$ |
An obstruction proximal to the sample site |
|
|
What abdominal/ pelvic veins exhibit pulsatile flow? |
IVC, hepatic, renal, veins draining into the ivc |
|
|
What abdominal/ pelvic veins exhibit continuous flow? $$$ |
Portal, splenic, and mesenteric veins |
|
|
Where is pulsatile flow abnormal?$$$ |
Lower extremities, indicative of venous hypertension often secondary to right heart failure |
|
|
Extrinsic compression |
Pressure exerted on vein due to overlying or adjacent structure |
|
|
Superficial system abnormal reflux $$$$$ |
Retrograde flow >0.5 sec |
|
|
Deep system reflux$$$ |
Retrograde flow > 1.0 seconds |
|
|
What position should reflux studies be performed in? |
Pt should be standing. If not it should be mentioned in report and considered in interpretation. |
|
|
When is valsalva acceptable in reflux studies?$$$ |
Only acceptable in proximal segments |
|
|
Primary flow patterns in abdominal veins$$$ |
Pulsatile or continuous flow |
