I was told that the venogram is complementary to the ultrasound you've had. The surgeon had already determined the need for surgery w/the ultrasound but he wanted it to see the condition of my compressed vein. I didn't get to look at the ultrasound pix yet but it may also be very convincing. I recall that you had very large numbers on your ultrasound so you may not need a venogram. Is it to convince you? Dr Sanders guideline for the scalene block was that it would be an indication of how I would likely FEEL after successful surgery & recovery.

At any rate I felt it was good for me to have a 2nd opinion so I'd feel comfortable going fwd with surgery. Having an experienced Dr like Sanders review my tests & records, give me an exam, the scalene block, test me for pec-minor syndrome, and evaluate my TOS was well worth the trip.
