Cephalic IVC question
Hi, all. Noob question...
According to this photo, the cephalic vein runs in a kind of distal + medial -> proximal + lateral direction, whereas the accessory cephalic vein runs straight down the leg. I would've thought ideal IVC placement would be into the accessory vein, but this tutorial says I should avoid the "accessory" vein whilst seemingly pointing to the main cephalic vein:

So, I'm a little confused. Is this diagram labelled wrong, or did the lady accidentally misname the cephalic vein? Where should I be placing my IVCs— in the purple, blue or green circle?
TIA
