Why would the great saphenous vein be removed during thigh lift surgery ?Isn’t it vital for oxygen delivery during recovery ? When I was having my markings before my operation my surgeon pointed it out since it was prominent that he would have to be careful around it. I had noticed it was no longer visible. I had an ultrasound with a vascular surgeon and she was confused as why I didn’t have it. My recovery did not go well and a year later I am still looking for answers.
