The phenomenon of ipsilateral innervation. One case report

Area of Science:

• Neurosurgery
• Neurology
• Cerebrovascular disease

Background:

• Anterior communicating artery aneurysms are complex cerebrovascular lesions.
• Surgical intervention often involves managing critical feeding vessels.

Observation:

• A patient developed homolateral hemiparesis after surgical occlusion of the left anterior cerebral artery.
• This occurred during treatment for an anterior communicating artery aneurysm.

Findings:

• Clinical presentation and follow-up studies (angiography, EEG, PEG) suggest ipsilateral innervation.
• The left anterior cerebral artery may influence motor control on the same side of the body.

Implications:

• This case challenges the typical understanding of contralateral motor control pathways.
• Further research into brain lateralization and functional recovery is warranted.
• Findings may inform surgical strategies for complex aneurysms.
