A cerebral aneurysm, also known as a brain aneurysm or intracranial aneurysm, is a potentially life-threatening condition where a weakened section of a blood vessel in the brain begins to balloon or bulge outward. This bulging area can remain asymptomatic for years, but it carries the serious risk of rupture, which can lead to a hemorrhagic stroke, permanent neurological damage, or even death.
At Neuro Doctors, our experienced neurosurgical team is equipped with advanced diagnostic tools and surgical techniques to provide accurate diagnosis and effective treatment for patients with cerebral aneurysms. Our goal is to deliver patient-centric, minimally invasive care that prioritizes both safety and outcomes.
A cerebral aneurysm develops when the wall of an artery in the brain becomes thin or weakened. Over time, the pressure of circulating blood causes the area to bulge out like a balloon. This bulge can put pressure on surrounding brain tissue or nerves. In some cases, the aneurysm may rupture, leading to internal bleeding known as subarachnoid hemorrhage, a medical emergency that requires immediate intervention.
Most aneurysms develop in the arteries at the base of the brain, especially in the circle of Willis, a ring of arteries that supply blood to the brain. The exact cause of aneurysm formation is not always clear, but it can be linked to several factors, including:
Genetic predisposition
Hypertension (high blood pressure)
Atherosclerosis
Head trauma or brain injury
Infection
Smoking and substance abuse
Cerebral aneurysms can be classified into different types based on their shape and location:
Saccular (Berry) Aneurysm: The most common type, resembling a small sac or berry attached to an artery. These account for about 90% of all intracranial aneurysms.
Fusiform Aneurysm: A spindle-shaped bulge encompassing the entire circumference of the vessel wall.
Mycotic Aneurysm: Caused by an infection that weakens the arterial wall.
Traumatic Aneurysm: Develops after a head injury that damages the blood vessel wall.
Unruptured aneurysms may remain silent and undiagnosed. However, in some cases, larger aneurysms may press on nearby nerves or brain tissue and cause:
Localized headaches
Blurred or double vision
Drooping eyelids
Numbness or weakness on one side of the face
Difficulty speaking or understanding speech
Seizures
If an aneurysm ruptures, symptoms appear suddenly and include:
A sudden, severe headache (often described as “the worst headache of one’s life”)
Nausea and vomiting
Stiff neck
Sensitivity to light
Loss of consciousness
Seizures
Timely diagnosis is critical in preventing aneurysm rupture or managing its aftermath. At Neuro Doctors, we use a range of advanced imaging tools to detect and evaluate cerebral aneurysms:
CT Scan (Computed Tomography): Often the first imaging test in emergency settings.
CT Angiography (CTA): Provides detailed images of blood vessels in the brain.
MRI / MRA (Magnetic Resonance Imaging / Angiography): Offers high-resolution imaging of the brain and blood vessels without radiation.
Cerebral Angiogram (Digital Subtraction Angiography): A highly detailed test considered the gold standard for visualizing brain aneurysms.
Treatment depends on the aneurysm’s size, type, location, and the overall health of the patient. Our multidisciplinary team evaluates all aspects before deciding on the most effective course of action.
Small, unruptured aneurysms that are not causing symptoms may only require routine monitoring with regular imaging and medical management of risk factors such as blood pressure.
One of the most effective treatments, aneurysm clipping involves placing a small metallic clip at the base of the aneurysm to stop blood flow into it. This is a proven technique that has been used for decades to prevent rupture or rebleeding.
Performed through a craniotomy, clipping offers long-term protection and is ideal for accessible aneurysms, especially in younger patients or those with a low surgical risk profile.
This minimally invasive procedure involves inserting coils through a catheter into the aneurysm to induce clotting and prevent rupture. While it avoids open surgery, it may not be suitable for all types of aneurysms.
These are used in more complex or larger aneurysms. A stent is placed within the parent blood vessel to redirect blood flow away from the aneurysm sac.
Our team at Neuro Doctors is led by highly experienced neurosurgeons and supported by interventional neuroradiologists and critical care experts. We bring together advanced surgical capabilities, modern neuroimaging, and evidence-based practices to offer patients:
Early and accurate diagnosis
Personalized treatment plans
Advanced surgical and endovascular techniques
Round-the-clock post-operative care and monitoring
High success rates and improved long-term outcomes
We also provide rehabilitation support and lifestyle modification advice to help patients recover and maintain optimal brain health.
While not all cerebral aneurysms can be prevented, you can reduce your risk by:
Managing high blood pressure
Avoiding smoking and recreational drug use
Maintaining a healthy diet and weight
Regular physical activity
Undergoing routine checkups if you have a family history of aneurysms
