  1. What are the four normal characteristics of veins?
    1. Spontaneity

  2. What is the meaning of spontaneity?
    picking up venous flow without help from maneuvers.
  3. What is the normal spontaneity of veins?
    veins should have spontaneity
  4. If the tibial and peroneal veins do not have spontaneity can that be still be considered normal?

    response to cardiac cycle

    should stop.

    If not its reflux

    • 2.) Sclerotherapy
    • 3.) New valves
    • 4.) Compression stockings
    • 5.) Una boot and medication
    • 6.) RFA ablation
    • 7.) ELVS ablation
  19. What happens with sclerotherapy?
    inject saline solution into the reticular (spider) veins

    Clotting occurs

    Wrap in bandage and put compression stockings on.
  20. What is used to help heal venous ulcers?

    • 1.) Check for reflux on a tilt table.
    • 2.) Check for DVT
    • 3.) Find out how bad the reflux is = severity
    • 4.) Measure vein size (diameter)
    • 5.) Map the vein and any tributaries or perforators coming from the vein
    • 6.) May need to find most optimal access point to enter the vein
    • 7.) Note any aneurysmal areas or largest diameter size that is not throughout
  24. What is the term used for branches of the main vein appearing to go above the layer of fascia?
  25. What is the term used for branches of the main vein appearing to go below the layer of fascia?
  26. Why is it important to measure the correct diameter of the vein to be ablated?
    need to know the size of catheter to be used.
  27. What must a sonographer do when a patient is on a tilt table?


    What can help with this?
    Check on patient. Patient can pass out.

    Blood pooling in legs and repeatively doing valsalva stops blood flow from returning to hear.

    Have patient take deep breaths and more feet/toes to help return blood.
  28. What name of vein changes when it becomes varicosed?

    What name does it change to?
    Posterior thigh circumflex vein

    Giacomini vein
  29. What specific perforators become the most problematic?

    Posterior tibial perforators

    B/C in gaitor zone and increase in hydrostatic pressure.
  30. What do perforators do?
    connect superficial veins to deep veins
  31. After an ablation of GSV, what should you check in the follow up? (3)
    1.) make sure there is still flow within the superficial epigastric vein.

    2.) check for DVT

    3.) check if ablation was successful
  32. How long most the reflux be to be considered:

    Normal =
    Mild to Moderate =
    Moderate =
    Severe =
    Normal = < 0.5 seconds

    Mild to Moderate = 0.5 to 1 second

    Moderate = 1 to 2 seconds

    Severe = > 2 seconds
  33. What is another test that a sonographer could use to test for valve competence?
    Never do?
    What be normal?
    What would be abnormal?
    • PPG testing
    • Place PPG sensor above the medial malleolus 10 cm. Empty calf by heal toe raises.
    • Never over varicosities
    • Normal = >= 20 secs.
    • Abnormal = < 20 seconds = valves not competent.
  34. What is a test that can be done to test if reflux is in the superficial vs. the deep system?
    Compress of the superficial system by inflating a cuff 20 mmHg or use an tourniquet.

    What else?(4)

    • 1.) congential
    • 2.) can be totally absent or hypoplastic (they are there but non-functioning, underdeveloped.)

    Arterial/ Venous malformations in cerebral vessels like an A-V fistulas.

    Is it congenital?

    • 1.) White leg (milk leg)

    Alba dolens
  40. What can cause Alba dolens?
    Arterial spasms that occur secondary to extensive acute iliofemoral vein thrombosis.

    So clot pushes on arteries and causes them to spasm
  41. What is the main explaination for Phlegmasias?
    Blood can't get out because DVT occlusion


    Blood can't get in because clots pushing on arteries.
  42. What are the 3 main symptoms of Cerulea dolens?

  45. What is it called when there is slow sluggish flow which will eventually clot?
    Roleau Formation
  46. What is Ascending Venography used for?

    How is it done?
    Evaluate for DVT or congential abnormalitites or chronic venous obstruction

    Inject contrast into dorsal vein in the foot.

    Incompetency in venous valves
  48. What are 4 limitations to venography?

    when the clot is above the knee
  52. Draw the venous spectral for lower extremity.
    Increase in flow with expiration.

    Decrease in flow with inhalation.
  53. Draw the venous spectral for upper extremity.
    Increase in flow with inspiration.

    Decrease in flow with expiration.
