I know you're not privy to exactly what's going on with him, but you do know a lot about blood clots.

Yeah, for sure.

So I think the place to start here and the thing we need to define is what's the difference between a superficial blood clot and a deep blood clot? Because originally he was diagnosed with a superficial thrombophlebitis and then that's progressed to a DVT.

Now in the lower extremity veins, we have two sets of veins.

We have a superficial system that sits just below the skin in the subcutaneous tissues, but it does not live between the muscles.

The deep system is a deeper set of veins that lives between the muscles.

The conventional thinking that we typically see is that the deep system is what puts you at risk for those clots to dislodge and that can travel most likely to your lungs.

How safe is he right now, and is he safe right now?
