Obviously the SCD is a DVT prophylaxis and traditionally the presence of an acute DVT is a contra-indication for its use. Certainly the age of the thrombus would make a difference. Older thrombus (hypoechoic with little change in echogenicity with external compression) are generally attached to the vein wall reducing the risk of embolization. 

However, today DVT is commonly treated in the outpatient setting, with little change in patient activity, except leg elevation when sitting or laying down. The increase in venous velocity during walking is significantly higher than the velocities achieved with the SCD. 

An emboli from a  isolated short segment calf vein thrombus below the confluence of the tibial or peroneal veins or the tibial - peroneal confluence is small and most likely would not produce any symptoms. As the thrombus approaches the confluences they tend to also increase in length increasing the likelihood of symptoms and fatalities.

Also, it could be argued that continued use of the SCD in short segment isolated acute calf vein thrombosis may enhance recanalization.

Unfortunately, just like the treatment of calf vein thrombosis there is no right answer. As with the treatment of DVT an individualized plan based on patients risk factors, diagnostic results, and physical condition is probably the most appropriate.

Sorry I couldn't give you a black & white answer.

Subject: SCD's on a patient with calf clot


I am currently not working as a vascular tech but I'm in the hospital and there 
is a patient on our floor who was diagnosed with a calf clot 2 days ago, the 
report does not indicate if it is acute or chronic but when I was working with 
the vascular dr's I know they typically did not take the SCD's off patients with 
calf clots. The PT was asking questions about it because our dr d/c the SCD's 
thinking it would cause the clot to propogate into a PE. 

Please let me know your thoughts. 
Thank you !
