22mm dilated veins

[Liver14]

Had to go to a&e and found out from the gp that my blood flow in my veins in my liver are flowing correctly and liver looks fine, but a vein is showing dilation of 22mm.

-Does anyone know what this means and how it can be treated?

I also had a CT scan today, does anyone know how long it takes to get the results back ?

Sorry for all the questions 🤪
