BRAIN ANEURYSMS

---

A brain aneurysm, also known as a cerebral aneurysm, is a weak spot in the wall of a blood vessel in the brain that bulges or balloons out. If the aneurysm leaks or ruptures, it can cause bleeding in the brain, known as a hemorrhagic stroke, which can be life-threatening.

Brain aneurysms are relatively common, affecting about 1 in 50 people. However, most aneurysms do not rupture. They are more common in adults than children and more frequently occur in women than in men.

Many brain aneurysms do not cause symptoms and are only found during imaging tests for other conditions. When symptoms do occur, they may include:

• Severe headache (often described as "the worst headache of my life")
• Nausea and vomiting
• Stiff neck
• Blurred or double vision
• Sensitivity to light
• Seizures
• Loss of consciousness
• Drooping eyelid
• Weakness or numbness on one side of the body
• Difficulty speaking

Diagnosing a brain aneurysm involves several steps:

• Medical History and Physical Exam: Your doctor will ask about your symptoms and perform a physical examination.
• Imaging Tests: Various imaging tests are used to detect aneurysms:
  • CT Scan (Computed Tomography): A detailed X-ray that can show bleeding in the brain.
  • MRI (Magnetic Resonance Imaging): Provides detailed images of the brain and blood vessels.
  • Cerebral Angiography: A procedure where a special dye is injected into the bloodstream to highlight blood vessels in the brain on X-ray images.
  • CT Angiography (CTA) and MR Angiography (MRA): Specialized scans that provide detailed images of blood vessels.

The treatment for a brain aneurysm depends on its size, location, and whether it has ruptured. Options include:

• Observation: Small, unruptured aneurysms that are not causing symptoms may be monitored with regular imaging tests.
• Medications: Drugs can be prescribed to manage symptoms and reduce the risk of rupture, such as controlling high blood pressure.
• Surgical Clipping: A neurosurgeon places a small metal clip at the base of the aneurysm to stop blood flow into it, preventing rupture.
• Endovascular Coiling: A minimally invasive procedure where a catheter is inserted into the bloodstream, and tiny coils are placed inside the aneurysm to induce clotting and seal it off.
• Flow Diversion: A newer technique where a stent is placed in the blood vessel to divert blood flow away from the aneurysm, promoting healing.

There are different surgical techniques for treating brain aneurysms:

• Craniotomy and Clipping: This involves opening the skull to place a clip on the aneurysm. It is typically used for accessible aneurysms that require direct intervention. This method provides more curative results compared to endovascular techniques. 
• Endovascular Procedures: These are less invasive and involve navigating a catheter through blood vessels to the aneurysm site. Techniques like coiling and flow diversion fall under this category.

Early detection and treatment of brain aneurysms can prevent serious complications and improve outcomes. If you experience symptoms or have concerns about brain aneurysms, it's important to consult your healthcare provider for a thorough evaluation.
