Learning Objectives 1. Learn technique for DVT Ultrasound. 2. Understand difference between Emergency/POC and formal DVT Ultrasound. 3. Learn pearls and pitfalls to DVT Ultrasound.
As a Sonographer for over 20 years i just had a few things to add: In Radiology it is common practice to complete your compressions down entire leg. I would say from my experience there are just as many proximal clots as mid thigh clots. Tip for augmentation is to have them flex big toe. That just establishes assumed flow for a longer distance while scanning in pop fossa compared to squeezing the calf. Great presentation
minivanmom I have a slightly swollen area on my upper outer thigh. Should I get an ultrasound for that? None of the ultrasound videos I've watched scan that area so I'm assuming it's considered unimportant and not likely to cause issues. Is that correct?
Hey Dawn, was wondering once someone has a positive acute thrombus how long does it normal take to become chronic? Like 2 weeks or 3 months? Or is there not really a usual time
The general teaching is that you should not augment when a DVT is present, for risk of embolizing that clot proximally. However, there is no case documented that has ever happened. Remember that every time the patient takes a step with a DVT, they are contracting their calf muscles and therefore augmenting. We do not tell patients to stop walking when they have a DVT. On the other hand, augmentation can help us to clearly identify the vessel and offers us secondary evidence that a DVT may be present.

Informative for my fellow sonographers
Very good presentation. Thanks a lot.
Very useful video , great thanks
Once more, many thanks!
great explanation ! thx for posting
Very helpful points!! thanks!
nice done. thx a lot

great!
excellent
Thanks
so do we completely avoid augmenting if a thrombus is found, or you just skip augmentation at the location of the clot?

shouldn't augment IF Dvt is found during compressions

very perfect for anyone, who work in hospital.
