Regarding brain mri report. Or vein?

I am attaching my brain mri report.I am confused about it ..one line is mentioned that Branch vein is seeing traversing above left trigeminal nerve and no contact with trigeminal nerve is on both sides.. my question is 1) What is branch vein?? Is it Sca artery or vein as both are vessels 2) What is traversing ?? Going above through trigeminal nerve without touching it?? And is it normal finding among some people ?? like this much proximity between trigeminal nerve and vein or artery or this is problematic thing. As no contact is mentioned then can in fiture it can be touched like if it is vein then chance is less but if its artery then as it is pulsatile so chance is there so i am worried,Kindly give answers only properly ..Main query is meaning of branch vein ?? Artery or vein??
