At the moment I am inclined to wait. That was also the suggestion from experienced TOS surgeon I believe. His rational is that even by doing the surgery there is no guarantee I wont reclot as the vein is damaged and even without mechanical pressure it can potentially reclot. The other thing is that I have developed a lot of collaterals which are helping the main (subclavian) vein. Even if I reclot I have a backup in these collaterals. By doing the surgery there is a risk of these fine veins being damages so I am back to only the main subclavian. He also predicts around 10% of reclotting if I take myself of blood thinners. At the moment (thank God) Xalerto has been great (no issues, very convenient drug) and I dont think I'll be doing the surgery anytime soon.
