What is sclerotheraphy? - ANSWERS-The injection of a sclerosing
solution, an irratant, into the vessel, resulting in its closure
-larger veins may be treated with this but foam sclerotheraphy is more
successful.
What is foam sclerotheraphy? - ANSWERS-A solution is injected as a
foam instead of a liquid.
Advantages of foam sclerotheraphy? - ANSWERS-1. Better
visualization while it spreads through targeted veins
2. Ability to use smaller amounts of solution
3. Better contact inside the veins due to the foam medium (it stays
longer and is not diluted by mixing with blood inside vein.)
What is surface laser treatment? - ANSWERS--Uses a precise amount of
light that is pulsed through a special hand piece in order to target the
vein or reddened skin area
-The absorbed light causes thermocoagulation of the treated blood vessel
What are reticular veins? - ANSWERS-1-3mm in diameter vein, dilated,
purple or bluish colored

What are primary varicose veins? - ANSWERS-Dilated, torturous
superficial veins that may be hereditary (result of congenital absence of
one or more valves.)
-increased venous pressure that causes primary varicose vein s is
unrelated to obstruction of deep venous system
What are secondary varicose veins? - ANSWERS-Caused by obstructive
conditions of the deep venous system, such as previous DVT, or
pregnancy; obesity May also be considered.
Why would you use a vena caval interruption device? - ANSWERS-In
patients with acute DVT who cannot be anticoagulated to prevent PE.
-main purpose is to catch thrombus that may break loose from deep vein
and embolize to heart and lungs
How is interruption device inserted? - ANSWERS-Using fluroscopy,
device is placed in IVC via the jugular or femoral vein
Where is IVC placed in body? - ANSWERS-Just below renal veins

Why would a iliofemoral venous thrombectomy be performed? -
ANSWERS-In a patient with impending limb loss (due to phlegmasia
cerulea dolens) if thrombolytic therapy does not dissolve the clot
Chronic venous insufficiency (CVI) occurs when? - ANSWERS-The
distal veins cannot maintain unidirectional blood flow proximally due to
valvular incompetence.
Primary cause of venous insufficiency is? - ANSWERS-Superficial
and/or deep venous reflux, (resulting in chronic ambulatory venous
hypertension)
What is portal hypertension? - ANSWERS-Elevated pressure in portal
vein, resulting from obstruction(increased resistance) of blood flow
Portal vein is formed by what two veins? - ANSWERS-1. Superior
mesenteric vein
2. Splenic vein
What is a transjugular intrahepatic portosystemic shunt (TIPS or
TIPSS)? - ANSWERS-Is a percutaneous procedure to create a
