Cerebral Aneurysm: Diagnosis & Treatment

Overview
An aneurysm is a vascular abnormality in which the wall of a blood vessel weakens, stretches, and forms a bulging sac. Most aneurysms are small (less than 10 mm), while those exceeding 25 mm are classified as giant aneurysms. If an aneurysm ruptures, it can cause a life-threatening brain hemorrhage.

Diagnosis
To detect and assess the size and location of an aneurysm, the following diagnostic tests are performed:

• CT Angiography – Uses contrast dye to visualize blood vessels and detect aneurysms.

• MRI – A highly accurate method that identifies aneurysms in 90% of cases.

• Cerebral Angiography (Transfemoral Access) – A detailed imaging test used to evaluate blood flow and confirm the presence of an aneurysm.

Treatment
The primary goal of treatment is to prevent rupture and cerebral hemorrhage. Surgical intervention is recommended based on aneurysm size, location, and risk factors.

Treatment Options:

• Aneurysm Clipping – A microsurgical procedure in which a metal clip is placed at the aneurysm’s base to block blood flow, offering a high degree of complete occlusion and long-term stability.

• Endovascular Embolization – A minimally invasive procedure in which coils or stents are placed inside the aneurysm to block blood flow and prevent rupture.
