What Are The Complications Of A Subarachnoid Hemorrhage

Meet Ella: From Brain Bleed to Coma to Survivor

After a subarachnoid hemorrhage, serious complications can occur. Swelling in the brain, or hydrocephalus, is one of the potential complications. This is caused by the build up of cerebrospinal fluid and blood between the brain and skull, which can increase the pressure on the brain. Subarachnoid hemorrhage can also irritate and damage the brain’s other blood vessels, causing them to tightenthis reduces blood flow to the brain. As blood flow becomes affected, another stroke can result, leading to even further brain damage. In serious cases, the bleeding may cause permanent brain damage, paralysis, or coma.

What Is Blood Pressure

Blood pressure is the vital force that propels oxygen-rich blood to all parts of your body. Your heart is the pump that generates the force, and your arteries are the channels that transport and distribute the blood.

The height of your blood pressure is determined by how forcefully your heart’s main pumping chamber, the left ventricle, contracts, and by the diameter and stiffness of your arteries. In turn, your heart and arteries are influenced by a large number of genetic, hormonal, metabolic, neurological, psychological, and lifestyle factors that determine your blood pressure. Because these influences are so numerous and complex, your blood pressure can vary from minute to minute and hour to hour during the course of the day, to say nothing of the slower shifts that occur over the course of a lifetime.

Blood pressure has two components. Your systolic blood pressure is the higher number, recorded while your heart is pumping blood into your arteries your diastolic blood pressure is the lower number, recorded when your heart is relaxing and refilling with blood between beats. Both numbers are calibrated in millimeters of mercury , a vestige of the mercury column used in the first pressure manometers more than 100 years ago. By convention, the higher number is recorded first a systolic pressure of 110 mm Hg and diastolic pressure of 70 mm Hg would be written as 110/70 and pronounced “110 over 70.”

What Happens To The Brain When There Is Bleeding Inside The Head

Since the brain cannot store oxygen, it relies upon a series of blood vessels to supply oxygen and nutrients. When a brain hemorrhage occurs, oxygen may no longer be able to reach the brain tissue supplied by these leaky or burst vessels. Pooling of blood from an intracranial hemorrhage or cerebral hemorrhage also puts pressure on the brain and deprives it of oxygen.

When a hemorrhage interrupts blood flow around or inside the brain, depriving it of oxygen for more than three or four minutes, the brain cells die. The affected nerve cells and the related functions they control are damaged as well.

What Happens When You Have A Brain Hemorrhage

According to informed health.org, when blood vessels inside the skull are damaged, it can lead to bleeding. This will increase pressure on the brain tissue because the brain has a limited amount of space inside the skull. In addition to pressure, this can cause blood clotting issues and damaged blood vessels .

One immediate effect a victim of a brain bleed may notice is a severe headache. If it isnt treated, it can lead to unconsciousness, respiratory affect, and irregular heartbeat. In the most serious cases, the victim may require nursing care due to devastating consequences like paralysis.

In this video, Dr. Rohan Moftakhar, Chief of Neurosurgery at Palmetto Health Richland, explains what happens to the brain during a hemorrhagic stroke.

Each childs outcome will vary depending on the size, cause, and location of the bleeding. Some children donât have any problems after treatment. Other children may have ongoing neurologic problems. These can include trouble with learning, speech, or movement. Some develop seizures or epilepsy. In these cases, regular follow-up with the doctor are needed. Supportive care, such as speech, physical, or occupational therapy, may also be needed.

How Frequently Does Brain Bleed Happen After A Stroke

Brain bleed may happen to anywhere from 10% to 40% of patients with an ischemic stroke. Different studies have identified various things that increase or decrease the risk of brain bleed after a stroke.

We will look at a few of those factors here:

  • The size of the stroke: The larger the initial stroke, the higher the risk of bleeding afterwards.
  • A stroke caused by an abnormal heart rhythm called A fib: A fib, or atrial fibrillation, is a condition in which the upper heart chambers dont beat regularly. It causes some turbulence in the blood flowing into the heart, increasing the risk of forming small blood clots that may go into the brain and block small blood vessels, causing a stroke. They usually result in multiple small strokes. These small clots can move again, exposing fresh blood into the damaged brain, causing brain bleed after the stroke. According to a study, people who get brain bleed after a stroke are 4 times more likely to have A fib than not.
  • Bad symptoms from the initial stroke: If someone had very bad symptoms from the initial stroke, he or she is also at an increased risk of brain bleed after that stroke. Doctors use a scale called the stroke scale or stroke score to keep track of the severity of the stroke. It goes from 0 to 42, where 42 is the most severe form of a stroke. The higher the stroke scale, the higher the chance of brain bleed afterwards.
  • What Is Intracerebral Hemorrhage

    If an artery in the brain bleeds directly within the brain tissue, it is known as an intracerebral hemorrhage. This type of stroke is often simply called a brain hemorrhage.” The blood that flows out presses against the tissue from the inside and pinches off other blood vessels in that area. The surrounding brain tissue then dies as it does in a stroke caused by a blocked artery.

    Depending on the function of that part of the brain, this can cause problems with vision, speech, movement, or sensation. Like a subarachnoid hemorrhage, intracerebral hemorrhage can lead to life-threatening complications, especially if a lot of blood flows out.

    Cost And Benefits Of Retaining A Traumatic Brain Injury Lawyer

    Claimants should discuss their legal rights with a lawyer following their initial recovery. Brain injury attorneys generally offer free case consultations and delayed fee representation agreements. Most brain injury lawyers do not require financial retainers or charge by the hour. Instead, they typically accept viable brain injury cases on a contingency fee basis and even front the money for necessary legal fees and costs. This structure means claimants can benefit from having legal representation without worrying about additional bills or paying if the attorney cannot recover damages.

    What Exactly Happens When A Person Is Going Through Stress

    Is high blood pressure bad for my brain?

    The person is going to stress it results in a higher level of cortisol and other stress hormones. According to a specialist performing brain hemorrhage surgery in Jaipur, the level of stress is different with every individual, and the disruption in the sleep cycle is the major contributor behind it. It is also responsible for increasing the blood sugar level due to which vessel cannot dilate or contract and there is interference in the blood flow.

    Can People Recover From Brain Hemorrhages And Are There Possible Complications

    How well a patient responds to a brain hemorrhage depends on the size of the hemorrhage and the amount of swelling.

    Some patients recover completely. Possible complications include stroke, loss of brain function, seizures, or side effects from medications or treatments. Death is possible, and may quickly occur despite prompt medical treatment.

    What Are The Complications Of Having A Subdural Hematoma

    Without treatment, large hematomas can lead to coma and death. Other complications include:

    • Brain herniation: Increased pressure can squeeze and push brain tissue so it moves from its normal position. A brain herniation often leads to death.
    • Repeated bleeding: Older adults who are recovering from a hematoma have a higher risk of another hemorrhage. Older brains dont recover as quickly as younger brains. Also, as we age, our brains shrink and the space between the skull and brain widens. This further stretches the tiny thin veins between the outer membrane layers of the brain and skull and makes the older brain more vulnerable to future bleeding if another head injuries occur.
    • Seizures: Seizures may develop even after a hematoma has been treated.

    If a brain aneurysm or an artery that passes over the surface of the brain bursts, blood flows into the fluid-filled space around the brain. Doctors call this area the “subarachnoid space.” Bleeding into this space is called a subarachnoid hemorrhage.

    Blood can then quickly spread in this space and put pressure on the whole brain. This means that even parts of the brain that aren’t very close to the bleeding blood vessel are damaged. The bleeding quickly causes a severe headache. Left untreated, it often leads to unconsciousness and life-threatening complications like an irregular heartbeat and respiratory arrest .

    The brain damage can cause long-term or permanent problems in everyday life, or lead to the need for nursing care for instance because of speech problems or paralysis.

    How The Size And Location Of Brain Bleed After A Stroke Makes A Difference In The Final Outcome

    What Is a Brain Bleed and What Causes It?

    Not all brain bleed after strokes cause a worse outcome than the original stroke. In fact, small amounts of blood leaking out after a stroke may be a sign that blood is flowing again in that part of the brain, signaling a better outcome. Many small brain bleeds after strokes may go undetected, because patients may not feel any worse with brain bleed than how they felt with the initial stroke.

    In general, if the bleeding occupies 30% or more of the area of the brain affected by the stroke, the outcome will likely be worse. The larger the bleeding, the worse the expected outcome can be.

    The location of the brain bleed and whether it is pushing on the surrounding brain tissue also makes a significant difference in the outcome. When the bleeding is in a confined area, it generates higher pressure and pushes on a part of the brain not affected by the initial stroke. That can lead to worsening symptoms, as the previously normal part of the brain begins to deteriorate with pressure.

    What Will Happen During A Craniotomy

    • The person will be given general anesthesia to keep him or her asleep and free from pain during surgery. The surgeon will make an incision in the person’s head. He or she will use tools to remove part of the person’s skull. He or she will also make an incision in the tissue that surrounds the person’s brain . The incision will let extra fluid or blood out of his or her brain. This will help decrease pressure and prevent injury to the person’s brain. The surgeon may insert tools through the incision to stop bleeding or remove a blood clot.
    • The surgeon may place a device in the person’s brain tissue. The device can be used to remove blood or fluid, and decrease pressure in the skull. It can also monitor pressure inside of the person’s skull. The surgeon will close the incision in the person’s brain tissue with stitches. The bone piece will be put back in the person’s skull and held with metal plates. The surgeon will close the person’s head incision with stitches or staples. A bandage will be wrapped around his or her head.

    How Is Subarachnoid Hemorrhage Diagnosed

    If you have symptoms of a subarachnoid hemorrhage, a doctor might use several tests to diagnose it:

    • MRI scan. This test uses large magnets, radiofrequency energy, and a computer to make detailed images of the brain.

    • CT scan. This test uses X-rays and computer technology to make horizontal, or axial images of the brain. CT scans are more detailed than general X-rays.

    • Angiogram. During this test, dye is injected in the blood vessel and then X-rays are taken to evaluate blood flow through them.

    • Spinal tap. In this test, a special needle is placed into the lower back, into the spinal canal. The pressure in the spinal canal and brain can be measured. A small amount of cerebrospinal fluid can be removed and analyzed for the presence of blood

    A diagnosis of a cerebral aneurysm isn’t usually made until a subarachnoid hemorrhage has already occurred.

    What Can I Expect If I Have A Subdural Hematoma

    If you have a subdural hematoma, your prognosis depends on your age, the severity of your head injury and how quickly you received treatment. About 50% of people with large acute hematomas survive, though permanent brain damage often occurs as a result of the injury. Younger people have a higher chance of survival than older adults.

    People with chronic subdural hematomas usually have the best prognosis, especially if they have few or no symptoms and remained awake and alert after the head injury.

    Older adults have an increased risk of developing another bleed after recovering from a chronic subdural hematoma. This is because older brains cannot re-expand and fill the space where the blood was, leaving them more vulnerable to future brain bleeds with even minor head injuries.

    What Are The Symptoms Of Brain Bleeding

    Hemorrhagic Stroke (Brain Hemorrhage)

    The symptoms of a brain hemorrhage can vary. They depend on the location of the bleeding, the severity of the bleeding, and the amount of tissue affected. Symptoms tend to develop suddenly. They may progressively worsen.

    If you exhibit any of the following symptoms, you may have a brain hemorrhage. This is a life-threatening condition, and you should call 911 or go to an emergency room immediately. The symptoms include:

    • A sudden severe headache
    • An abnormal sense of taste
    • Loss of consciousness

    Keep in mind that many of these symptoms are often caused by conditions other than brain hemorrhages.

    Brain Bleed After A Stroke

    Brain bleed after a stroke and a stroke from a brain bleed are different things. Brain bleed after a stroke happens in people who have regular strokes and later develop bleeding inside the brain. In some cases, brain bleed after a stroke is a side effect of treatment for a regular stroke.

    If you would like to know the difference between a regular stroke , and a stroke from a brain bleed , read this article.

    This article here will focus on brain bleed after an ischemic stroke. We will explore the following topics:

    Blood can also leak into the small gaps between the meninges or between the meninges and the skull:

    • If veins in the brain are damaged, for example as a result of a fall, blood may leak into the space between two meninges known as the arachnoid mater and the dura mater. The medical term for this kind of bleeding is a subdural hematoma.
    • If an artery that supplies the meninges with blood is damaged, bleeding known as an epidural hematoma may occur. The blood then leaks into the space between the skull bone and the tough membrane covering the brain . Like other types of bleeding in the brain, subdural and epidural hematomas can cause severe brain damage.

    What Are The Symptoms Of Brain Bleeds

    Symptoms of a brain hemorrhage depend on the area of the brain involved. In general, symptoms of brain bleeds can include:

    • Sudden tingling, weakness, numbness, or paralysis of the face, arm or leg, particularly on one side of the body.
    • Headache.
    • Nausea and vomiting.
    • Loss of vision or difficulty seeing.
    • Loss of balance or coordination.
    • Stiff neck and sensitivity to light.
    • Abnormal or slurred speech.
    • Difficulty reading, writing or understanding speech.
    • Change in level of consciousness or alertness, lack of energy, sleepiness or coma.
    • Trouble breathing and abnormal heart rate .

    What Is A Haemorrhagic Stroke

    Brain Bleed

    If blood leaks from a blood vessel in or around the brain, this is called a haemorrhagic stroke. You may also hear it called a brain haemorrhage or a brain bleed.

    In the UK, around 15% of strokes are haemorrhagic , and about 85% are ischaemic .

    Haemorrhagic stroke tends to affect younger people than ischaemic stroke, and is most common in people aged between 45 and 70. Most strokes in the UK happen over the age of 70.

    There are two main types of haemorrhagic stroke:

    • Bleeding within the brain: called an intracerebral haemorrhage, or intracranial haemorrhage .
    • Bleeding on the surface of the brain: called a subarachnoid haemorrhage .

    Bleeding within the brain

    When an artery inside the brain bursts its called an intracerebral haemorrhage. About 10% of all strokes are of this type.

    The blood leaks out into the brain tissue at high pressure, killing brain cells and causing brain swelling.Bleeding on the surface of the brain

    The brain sits inside a fluid-filled cushion of membranes that protects it from the skull, called the subarachnoid space. If blood vessels near the surface of the brain burst and blood leaks into the subarachnoid space, this is called a subarachnoid haemorrhage .

    SAH accounts for around 5% of all strokes, and it is most often caused by a burst aneurysm .
