How to: Ultrasound assessment of proximal DVT - 2 March 2023

Scanning proximal DVT can be tricky!
However as with anything ultrasound, the key to evaluating is taking a systematic approach. In this Coaching Corner Suean takes you through a systematic 5 step method that guides you from groin to calf. By applying this approach, in combination with the 3Ps, you'll be scanning with ease in no time flat.
PLUS - reference was made to research on the coincidence of cellulitis and DVT. Access the article referred to here:

The yellowing on cable jackets is bleach-free disinfectant. There's several different chemical cocktails available so it's hard to pinpoint which ones do it or not.
