Popliteal arterial Aneurysms

Hello, hope I’m on the right group, as was told .
I had a minor knee issue and an ultrasound was one of the tests order to rule out a blockage.
Results were fine , except popliteal arteries seem big and and one of them borderline aneurysmal . 1.90 cm
At 2cm has to be treated and closely watched
Dr. Ordered another ultrasound in a year to see if it has grown.
Anyone with same issue? Thank you.
