Thanks for keeping us up to date jlrob6. With the extra information you've provided, I can see there is a bit of a road ahead for you. Be mindful that your CT results need clarifying as they are taken at rest. To clarify the CT result, I would recommend you ask for some Venography and a Doppler ultrasound, the later identifies the type of blockage on the vein, I expect you are referring to the subclavian.

Let us know how you go.
