A cerebral aneurysm is a bulge of a brain artery from a weakening or thinning of the blood vessel wall.
Brain aneurysms that burst can bleed into the brain, called a subarachnoid hemorrhage, and result in a stroke.
Cerebral aneurysms fall into three categories:
Saccular aneurysm. Sometimes called a berry aneurysm because it has a thin stalk similar to a berry with a stem, this is the most common type of brain aneurysm.
Fusiform aneurysm is enlarged in all directions.
Dissection aneurysm can develop from an injury that generates a fissure in the inner layer of the blood vessel wall. Blood may pool out on one side of the artery or it may block blood flow.
Causes and Symptoms of Cerebral Aneurysms
Researchers are still investigating the causes of brain aneurysms, but
high blood pressure,
abnormality in the artery wall, and
can all contribute to an aneurysm.
Often there aren’t any symptoms, and the arterial bulge is found during other diagnoses.
Unruptured aneurysm symptoms related to the eyes:
blurry or double vision
Other symptoms that can occur with a cerebral aneurysm rupture are similar to stroke symptoms such as:
nausea and/or vomiting
sudden and intense headache
numbness, weakness or paralysis of the face or limbs
If you think that you or your loved one is experiencing a rupturing aneurysm, enlist emergency medical expertise immediately.
How Is a Cerebral Aneurysm Diagnosed?
Highly developed medical imaging is used in diagnosing cerebral aneurysms:
Angiography that takes real time x-rays of your veins and arteries using fluoroscopy
Computed tomography (CT) scans
Magnetic resonance imaging (MRI)
State-of-the-Art Treatments for Cerebral Aneurysms at NSPC
If your aneurysm doesn’t present any symptoms and is small, your physician may recommend that you have regularly scheduled exams to keep a close watch on your condition. Depending on your specific condition, surgery may be the best treatment option.
The seasoned doctors at Neurological Surgery, P.C. (NSPC) provide the most up-to-date brain aneurysm treatments. Our highly skilled multidisciplinary team of neurosurgeons are leaders in the NY region’s medical community, with positions as chiefs of neurosurgery in some of Long Island’s best hospitals.
Minimally invasive endovascular coiling embolization. The endovascular neurosurgeon threads a narrow catheter from a small incision in the groin through the blood vessel and to the aneurysm site. A thin flexible coil is put in place to stimulate the clotting of the aneurysm.
Microsurgical clipping. During microsurgical clipping a tiny metal clip is placed around the ballooning artery to inhibit the blood flow into the aneurysm.
Cerebral Bypass. If the blood vessel has burst, but blood flow is still needed to a section of the brain. A neurosurgeon can occlude or block the blood flow to the aneurysm and then use a donor vessel to bypass the aneurysm, but still allow blood to circulate to that particular section of the brain.
