Blood tends to clot easily |
Hyper coagulable |
|
|
Venus stasis. Blood pools in the veins |
Hemodynamic changes |
|
|
Trauma or injury |
Vein wall injury |
|
|
Skeletal muscle contractions squeeze the veins to help flow against gravity of the heart |
Major factor |
|
|
During respiratory inspiration the Venus transiently increases because of a decrease in the right the opposite occurs during expiration |
Respiration |
|
|
Minor factor |
Hydrostatic pressure |
|
|
P TV, ATV, and peroneal are the main _ veins |
Calf |
|
|
The for moral vein or originates at the adductor which is also called what |
Hunters Canal |
|
|
_ have a phasic low velocity Doppler signal’s |
Veins |
|
|
_ Have triphasic high velocity Doppler signal |
Arteries |
|
|
Jugular, subclavian, auxiliary, brachial, radial, ulnar |
Deep veins in UEV |
|
|
Superficial veins |
Cephalic, basilic, medial cubital vein |
|
|
What are you have to do in order to augment the jugular |
Make the patients sniff |
|
|
Flow is present without augmentation |
Spontaneous flow |
|
|
Blood flow changes with respiration |
Respiratory phasicity |
|
|
Blood flow velocity increases with distal limb compression |
Augmentation |
|
|
Vein lumen partially filled, vein is filled with intraluminal echoes, absence of color or Doppler signal |
Abnormal venous Doppler interpretation |
|
|
What is the lab test that can be used to detect possible thrombus formation |
D – dimer |
|
|
Why is D dimer not completely correct |
The D dimer cannot specify where thrombus was formed things can cause elevated D dimer besides DVT. D dimer test has not been standardized |
|
|
What is the purpose of vein mapping |
To determine if the vein is suitable as a bypass conduit |
|
|
Lower extremity superficial veins are commonly used for what |
Bypass graft or lower extremity bypass |
|
|
How large does the vessel need to be in order for a doctor to use |
2 to 2.5 mm or larger |
|
|
What is venous reflux testing |
When the valves become damaged they will not close properly these incompetent bowels can cause chronic venous insufficiency |
|
|
What is it called when there is a common fluid collection seen in the popliteal fossa |
Baker’s cyst |
|
|
What is very sluggish flow seen as a heterogeneous internal echo within the vessel |
Rouleau formation |
|
|
What does rouleau mean |
Roll |
|
|
What can be the cause of pulsatile venous flow |
Congestive heart failure, this flow can be hard to image augmentation |
