I have bilateral arterial and venous TOS. What diagnostic tests and imaging studies have you had done (e.g., ultrasound, CT, arteriogram, venogram, etc.)? When you say vascular, is it the arterial or venous form? I will be getting partial rib resections on both sides in the coming months, and I've done endless research on this, as it is such serious surgery. I'm kind of surprised, if you have vascular TOS, that no rib surgery is involved, but if you could share any more details about the surgery, it would be interesting to me to hear about them.
