CHF and Pulm HTN  are two primary reasons veins would be pulsatile in the lower extremities

Pulsatility from a cardiac origin would be bilateral in "normal" limbs.
CHF and Pulm HTN  are two primary reasons veins would be pulsatile.
Other cardiac pathologies could affect venous hemodynamics as well but these would be the most general ie: CHF or pulm htn secondary to severe valvular pathology.
 
If it is unilateral then there may be several explanations:  Ask yourself a few questions when and if that is noted:
1. Has the pt had any recent interventional procedures? 
2. Has AV Fistula been ruled out?
3. Has Pseudoaneurysm ruled out?
 
4. Is there proximal obstruction or extrinsic compression in the contralateral limb that is preventing the veins on that side from otherwise appearing pulsatile? 
 
flownetters: what can you add?

Does anyone have a reference that explains how one can find pulsatility in one lower extremity (CFV and GSV) and not the other? Is it clinically significant if found in only one limb of a bilateral exam?  Thanks for the brain power!
