Vascular Surgical Anatomical Notes Related to The Insular
Lobe by Behzad Saberi in Integrative
Journal of Conference Proceedings
There is a close relationship between MCA and insula which is deeply located in the brain and such position and relationship, make surgical access to it to be more restricted. MCA supplies blood to the insular cortex. M1 part of the MCA via the lateral lenticulostriate arteries, supplies the underlying internal capsule and basal ganglia. M2 part of the MCA supplies the actual insular cortex.
Branches of the distal M1 and opercular M3 parts of the MCA, occasionally supply the insular cortex either. Avoiding to compromise the M2 part, is of surgical importance because it would be in the central sulcus and would supply it and also the precentral and postcentral gyri.
Vascular injuries during insular surgery in some parts, can cause motor deficit without directly affecting and causing lesions to the internal capsule. Primary motor-sensory cortex vascular compromise can be the result of the injury to central sulcus artery [1-4]. Hemiparesis due to a vascular capsular insult, can be seen in the lateral lenticulostriate arteries compromise, because the lateral lenticulostriate arteries which would arise from M1 part of the MCA, would supply the internal capsule either.
