Bleeding in the brain happens when blood vessels rupture or leak inside the brain. It is a serious medical emergency that requires immediate attention. The bleeding creates dangerous pressure on brain tissue and can lead to permanent damage or death without proper treatment.
Several factors can trigger brain bleeds. High blood pressure tops the list as the most common cause. Head injuries, brain aneurysms, blood vessel abnormalities, and blood disorders may also have an impact. This article will help you understand when surgery becomes necessary and help patients and families prepare for treatment decisions.
Common Causes of Brain Bleeding
Here are some of the most common causes of brain bleeding:
High Blood Pressure
High blood pressure damages blood vessel walls over time. This damage makes vessels more likely to rupture, especially small arteries deep inside the brain. When blood pressure stays high for years, it weakens these delicate vessels until they finally break.
Doctors call this type of bleeding a hypertensive hemorrhage. It often occurs in areas like the basal ganglia, thalamus, or brainstem. These regions control important functions like movement, sensation, and consciousness.
Head Trauma
Head injuries cause many brain bleeds, especially in younger patients. Falls, car accidents, and sports injuries can tear blood vessels inside the skull. Even mild head trauma can sometimes trigger bleeding hours or days later.
The brain sits inside the hard skull, surrounded by fluid. When the head hits something or shakes violently, the brain can bounce against the skull walls.
This movement stretches and tears blood vessels, causing bleeding between the brain and skull or within the brain tissue itself.
Brain Aneurysms
Aneurysms are weak spots in blood vessel walls that balloon outward. These bulges can form anywhere in the brain’s blood vessels. When an aneurysm ruptures, it causes sudden, severe bleeding.
Aneurysm bleeding often happens without warning. Patients may feel the worst headache of their life, along with nausea, vomiting, or loss of consciousness. This type of bleeding requires emergency treatment to prevent death.
Blood Vessel Malformations
Some people are born with abnormal blood vessel connections called arteriovenous malformations or AVMs. These tangles of vessels lack the normal structure that controls blood flow. The abnormal connections can rupture and cause bleeding.
AVMs may remain silent for years before causing problems. Some people discover them only after they bleed. Others may experience seizures or headaches before a rupture occurs.
Blood Disorders and Medications
Certain medical conditions affect blood clotting. Hemophilia and other bleeding disorders make it harder for blood to clot normally. When bleeding starts, it continues longer and becomes more severe.
Blood-thinning medications like warfarin or aspirin also increase bleeding risk. These drugs help prevent strokes and heart attacks by making blood less likely to clot. However, they also make any bleeding harder to stop.
Brain Tumors
Tumors can damage nearby blood vessels as they grow. Some tumors have their own blood supply that can leak or rupture. Cancer that spreads to the brain from other organs may also trigger bleeding.
Tumor-related bleeding often develops gradually. Patients may notice worsening headaches, confusion, or weakness on one side of the body.
When Bleeding in the Brain Surgery Becomes Necessary
A brain doctor will consider many factors when deciding if bleeding in the brain needs surgery.
Large Bleeds That Create Pressure
Surgery becomes essential when bleeding creates dangerous pressure inside the skull. The brain sits in a closed space with no room for extra blood. Even small amounts of bleeding can compress brain tissue and damage vital areas.
Doctors measure this pressure and watch for signs of brain compression. Symptoms include severe headaches, vomiting, confusion, and changes in consciousness. Pupils may become unequal in size or stop responding to light.
Location Matters
The location of bleeding influences surgical decisions. Bleeds in certain areas pose immediate threats to life. Bleeding in the brainstem, which controls breathing and heart rate, requires urgent intervention.
Surface bleeds between the brain and skull may need surgery to prevent further damage. Deep bleeding within brain tissue presents different challenges and may require specialized techniques.
Surgical Options Available
Here are some available options for surgery for bleeding in the brain:
Craniotomy
Craniotomy involves opening the skull to access the bleeding area. Surgeons remove a section of bone to reach the brain. They can then remove pooled blood and repair damaged vessels.
This approach works well for large bleeds or when surgeons need direct access to repair aneurysms. The bone section is replaced at the end of surgery.
Minimally Invasive Surgery
Newer techniques use small incisions and specialized tools. Endoscopic surgery allows surgeons to remove blood clots through tiny openings. This approach causes less trauma to healthy brain tissue.
Doctors can also use catheters inserted through blood vessels to reach some bleeding sites. These techniques work especially well for certain types of aneurysms.
Decompressive Surgery
Sometimes, surgeons need to relieve pressure quickly. Decompressive surgery removes part of the skull temporarily to give the brain room to swell. This prevents further damage while the brain heals.
The bone piece is typically replaced weeks or months later, once swelling goes down.
