venous insufficiency testing (textbook)

Phlebectomy

Surgical removal of varicose veins

Valsalva maneuver

Maneuver to increase intra-abdominal pressure and test the valve competency in the GSV, CFV, and femoral veins

Vein stripping

Surgically removing the great Saphenous vein

Venous ablation

Procedure to close off and seal incompetent superficial veins

Greater than 1 second

Abnormal reflux times for deep veins

Greater than 0.5 seconds

Abnormal reflux times for great and small Saphenous veins

Greater than 0.35 seconds

Abnormal reflux time for perforating veins

Hunterian

What is the name of the perforating veins located in the upper thigh?

Terminal valve

Incompetence in this valve often leads to the entire GSV being incompetent.

1 second

With the patient standing, what time value is the threshold between normal and abnormal reflux in deep veins

>3.5mm

Perforating veins exceeding this diameter has a high predictive value for being incompetent.

Insufficiency caused by congenital abcense of valves

Which of the following best describes venous insufficiency?

1. Insufficiency caused by chronic outflow obstruction

2. Insufficiency caused by congenital absence of valves

3. Insufficiency resulting from previous deep vein thrombosis

Popliteal

To assess venous reflux, the vasalva maneuver is suitable for all of the following veins EXCEPT:

1. Popliteal

2. Great Saphenous

3. Common Femoral

4. Proximal femoral

Sitting, leg dependent

Perforating veins should be evaluated in which position?

False, in the presence of an incompetent GSV retrograde flow can occur in the CFV during valsalva as it flows into the GSV.

T or F: Reflux flow in the CFV during valsalva always indicates deep vein incompetence

< 20 seconds

What is the abnormal reflux time for a PPG venous insufficiency test?
