Posterior Cerebral Artery Branches

Capture

<PCA.ppt>

4 anatomic segments of the PCA:

  1. P1 segment: from tip of basilar to origin of PComm
  2. P2 segment: from Pcomm to dorsal midbrain
    1. P2A – anterior segment
    2. P2P – posterior segment
  3. P3 segment: from lateral quad cistern at origin of post temporal artery to ant limit of calcarine fissure
  4. P4 segment:  terminal cortical branches of PCA after takeoff of parieto-occipital and calcarine arteries

Tract Hemorrhage Grading Scale

Tract hemorrhage grading scale adapted from Ko et al. 

Tract hemorrhag grading: grade 0 a—no hemorrhage, grade I b—minimal intraventricular hemorrhage or hematoma <1 cm, grade II c—hematoma ❤ cm, grade III d—massive IVH, hematoma >3 cm
