Surgery for Superior Cerebellar Artery Aneurysm

Area of Science:

• Neurosurgery
• Vascular Neurology
• Cerebrovascular Surgery

Background:

• Superior Cerebellar Artery (SCA) aneurysms constitute a small percentage (1-3%) of all intracranial aneurysms.
• The intricate anatomy of the SCA presents unique surgical approach considerations.

Purpose of the Study:

• To analyze the demographic, clinical, radiological, and treatment outcomes of patients with aneurysms treated at our center.
• To specifically investigate the management and outcomes of rare Superior Cerebellar Artery aneurysms.

Main Methods:

• Retrospective analysis of 167 aneurysm cases treated between January 2022 and May 2023.
• Detailed review of two surgically managed Superior Cerebellar Artery aneurysm cases, including surgical approaches and outcomes.

Main Results:

• Superior Cerebellar Artery aneurysms were found in 2 out of 167 (1.2%) treated aneurysm cases.
• Both Superior Cerebellar Artery aneurysm patients underwent successful surgical management.
• Overall, 69.3% of treated vascular cases were aneurysms, with good recovery outcomes in both surgical (79.1%) and endovascular (76.9%) groups.

Conclusions:

• Superior Cerebellar Artery aneurysms are rare and pose significant surgical challenges due to complex anatomy.
• Surgical approach selection is critical and depends on aneurysm location.
• Microsurgical treatment, with appropriate technique and experience, can yield favorable outcomes for Superior Cerebellar Artery aneurysms.
