Not AVM, just nasty

I went to the Diagnostic Imaging NW clinic to have ultrasounds taken of my crazy veins. They started on the top of my leg, looking for any deep thrombosis, which might indicate unknown clots or other issues. Then I rolled to my side so they could ultrasound the actual veins in question. The technician said it looks as though the blood flowed in only one direction, so in fact it is not an AVM just a nasty vein that seems to be creeping every so slowing northward.
