Anterior cerebral artery reconstruction.

Area of Science:

• Neurosurgery
• Vascular Surgery
• Cerebrovascular Anatomy

Background:

• Cerebral aneurysms frequently occur in the anterobasal interhemisphere.
• Effective surgical reconstruction of the anterior cerebral artery (ACA) is crucial for treating these aneurysms.

Observation:

• The study explored various microvascular reconstruction techniques for the ACA, including end-to-end, end-to-side, and side-to-side anastomoses.
• Grafting procedures using posterior cerebral artery segments were also investigated.
• Reconstructions involved the A1 and A2 segments of the ACA, the recurrent artery of Heubner (RAH), and orbitofrontal and frontopolar arteries.

Findings:

• Experimental reconstructions, including side-to-side anastomoses of A2 or A3 segments, were successfully performed.
• Three clinical cases involving ACA aneurysms were treated using these techniques (A1-A2 end-to-end, A2-A2 end-to-side, RAH end-to-end anastomosis) without technical difficulties or complications.

Implications:

• The findings confirm the feasibility of these microvascular reconstruction procedures in the challenging anterobasal interhemisphere region.
• This research provides a foundation for improved surgical management of complex ACA aneurysms.
• The study highlights the potential for enhanced treatment outcomes in cerebrovascular surgery.
