Cerebral Aneurysm

Several imaging techniques are used to detect and evaluate cerebral aneurysms:

• CT Angiography (CTA): Produces 3D images to identify aneurysms and their relationship to surrounding structures, aiding in surgical planning.
• Magnetic Resonance Angiography (MRA): A rapidly advancing diagnostic tool with detection rates exceeding 90%.
• Cerebral Angiography (Digital Subtraction Angiography, DSA/TFCA): Considered the gold standard for diagnosis, providing detailed information on aneurysm location, shape, size, direction, and associated vascular abnormalities. This method is more invasive, requiring catheter insertion and contrast injection.

The primary goal of treatment is to block blood flow into the aneurysm and prevent rupture. Treatment options include:

• Surgical Clipping: Involves placing a clip at the base of the aneurysm to stop blood flow. It has high durability and a low recurrence rate but requires open surgery.
• Endovascular Coiling: A less invasive technique in which coils are inserted into the aneurysm through a catheter, promoting clotting and sealing off the aneurysm. This method is associated with shorter recovery and is often preferred for older patients or those at higher surgical risk.

The choice of treatment depends on the aneurysm’s characteristics and the patient’s overall condition.
