Motivation: Territory supplied by lenticulostriate arteries includes deep subcortical grey matter nucleus which pose vast influence on neurological function.
Goal(s): To elaborate the modification of lenticulostriate arteries when middle cerebral artery occluded.
Approach: Patients with MCA occlusion were performed 7T time-of-flight MR angiography with voxel size of isotropic 0.3mm.
Results: Origination of LAS were modified to originated from the proximal end of occluded segment in 64.3%. While their morphometrical features were identical with the normal contralateral side LSA.
Impact: The finding may be helpful for the protection of LSA in endovascular procedure, and provide critical knowledge about the angiogenesis of middle cerebral artery. Future large sample size 7T MRI study is warranted.
