Artery of Percheron infarction
Most prevalent artery of Percheron infarction patterns are
- Bilateral paramedian thalamic with midbrain infarction (43%)
- Bilateral paramedian thalamic alone without midbrain involvement (38%)
- Bilateral paramedian thalamic infarction with anterior thalamic and midbrain involvement (38%)
- It’s a type of posterior flow infarction.
Preferred imaging modalities for prompt diagnosis of artery of Percheron infarction are diffusion-weighted imaging (DWI) and fluid-attenuated inversion recovery (FLAIR)
The investigations of choice for prompt diagnosis of artery of Percheron infarction are MRI diffusion-weighted imaging (DWI) and FLAIR MRI sequences.
