Be honest!
Do you say “thalamic infarct” & hope no one asks questions?
Or can you name thalamic vascular territories?
Know why the whole thalamus doesn’t infarct w/a PCA infarct?
Answer: It’s supplied both by PCA & PCOMM!
Here's what you NEED to know about the thalamus!
➡️Tuberothalamic
🔸From the PCOMM
🔸Supplies the anterior thalamus
🔸I call it the Top-o-the-thalamic to remember it's at the top anteriorly
➡️Paramedian
🔸Branch of the P1
🔸ParaMEDIAN is MEDIAL, so it supplies the medial aspect
➡️Posterior choroidal
🔸Supplied by the posterior choroidal artery
🔸Posterior choroidal is POSTERIOR—it supplies the back of the thalamus
➡️Thalamogeniculate
🔸Branch of the P2
🔸Geniculate is by the GENU of the internal capsule, so it's lateral by the internal capsule
Now you know the thalamic vascular territories & you won’t have lie when it comes to these guys!
