Morphology

perivascular = vascular (transparent) = peri + vascular

Built from the medical combining prefix 'peri-' meaning 'around' plus 'vascular'; the meaning 'around blood vessels' is directly compositional.

Etymology

Perivascular breaks into peri- meaning 'around', as in perimeter, and vascular meaning related to blood 'vessels'. So, perivascular means 'found around a blood vessel'.
