Are venous doppler studies used in the evaluation of venous stasis ulcers?
Doppler studies are done to exclude the presence of deep vein clots and to look for venous reflux disease, axial or perforator types. Duplex ultrasound is considered the test of choice for detailed evaluation of chronic venous reflux (insufficiency) - it combines color Doppler flow imaging with B mode and pulsed Doppler. It is very well documented that Duplex scanning is the most reliable, cost effective and quick method to identify venous insufficiency and obstructive venous disease.
Most recent studies have documented that the superficial and perforating veins are involved in most patients with venous stasis ulcers and those with recalcitrant and recurrent ulceration after inadequate conservative treatment.
