Exam 2 - Venous Doppler

Normal Venous Doppler Flow

Spontaneous

Respirophasic

Unidirectional

Augments with distal compression

Ceases with Valsalva maneuver

Pulsatile Venous Flow

Bidirectional pattern

Indicative of elevated right heart pressure

Upper Extremity Venous Protocol

Internal jugular

Brachiocephalic

Subclavian

Axillary

Brachial

Cephalic - prox/mid/dist

Basilic - prox/mid/dist

Radial

Ulnar

Normal Upper Extremity Venous Doppler Flow

Respirophasic

Cardiac Pulsatility

Diminished phasicity

Jugular Vein Valve

Basilic Vein

Terminates into the axillary vein in upper arm

Courses medially and superficially without a companion artery

Usually largest vein in upper arm region

Median Cubital Vein

Connects cephalic and basilic veins

Resides in the antecubital fossa

Common site of venipuncture - therefore thrombus

Lower Extremity Venous Doppler Protocol

External iliac

Common femoral

Profunda

Femoral - prox/mid/dist

Popliteal

Posterior tibial

Peroneal

Great saphenous - at junction

Normal Lower Extremity Venous Doppler Flow

Respirophasic

Spontaneous

Non-pulsatile

Augmentation Response

Valsalva Response
