A medical negligence lawyer who deals exclusively in personal injury claims will speak to you, giving free advice and information on how best to preserve your legal right to receive compensation as a result of injuries caused by medical negligence.

Cerebral Aneurysm - Negligence

A brain aneurysm is a weak part of an artery that bulges out from the main part of the artery. Aneurysms can have symptoms because they push on other brain structures and nerves. They can also have symptoms because they bleed, causing damage to the tissue of the brain. About 1 in 15 people will have a brain aneurysm in the brain; many come to be noticed when they rupture spontaneously. A ruptured aneurysm is sometimes referred to as a subarachnoid haemorrhage when they bleed into the arachnoid space. In such cases, the outcome is stroke, coma and death.

About 3,000 people in Canada have a subarachnoid haemorrhage every year. About 10-15 percent of people will die before reaching a healthcare facility and half will die in the first 30 days. The biggest risk factors are having a first degree relative with an aneurysm and smoking cigarettes. The average age of those presenting with an aneurysm is 40-60 years of age; males predominate at 3:2 and twenty percent will have more than one aneurysm.

The symptoms of a ruptured cerebral aneurysm are different from symptoms of an unruptured aneurysm. Symptoms of a ruptured aneurysm include the following:

  • Stiff neck.
  • Blurry vision.
  • Nausea and vomiting.
  • Dilated pupils, often on one side.
  • Pain behind the eye.
  • Loss of sensation.
  • Light sensitivity.

Symptoms of an unruptured cerebral aneurysm include the following:

  • Thinking problems.
  • Peripheral vision problems.
  • Speech difficulties.
  • Fatigue.
  • Short term memory deficits.
  • Poor concentration.
  • Loss of coordination.
  • Behavioral problems.
  • Problems with perception.

Aneurysms will rupture at a rate of about 1-2 percent per year. Unfortunately, most aneurysms don’t show themselves until they have ruptured. Large aneurysms can show themselves by interrupting vision, causing a nerve paralysis, nausea and vomiting, pain behind the eye or other symptoms related to the nervous symptom. CT scan can pick up these lesions before they rupture. MRI scans can also show the presence of cerebral aneurysms. CT scanning requires the US of contrast dye to show up the blood vessels, while an MRI does not require a dye at all. CT scan produces better resolution when done with a dye. A CT angiogram uses a dye and is the best test for detection of a ruptured aneurysm. If many aneurysms are found, the patient will have a cerebral angiogram to identify each of the different aneurysms.

The treatment of brain aneurysms is usually done when they haven’t ruptured. There are two main treatments of aneurysms. The first is called open surgical clipping, in which the surgeons go in and place a metal clip across the aneurysm where it comes across the main blood vessel. Patients spend 2-3 days in the hospital and are directed not to do heavy activity for a month after the procedure. This is an open procedure, requiring open brain surgery which occasionally results in negligence.

An easier procedure is called “endovascular coiling”. It is a closed procedure in which the surgeon goes into the arterial system of the brain with a coil. The coil is inserted into the aneurysm where it clots off the vessel because of lack of blood flow in the aneurysm. This is now considered the superior procedure, preferred over the open procedure. Stents or balloons may be necessary to keep the coil in place.

If the aneurysm has ruptured, external clips and endovascular coiling can be done, although the patient is in a risky situation. Patients with coils had a 22.6 percent lesser risk of disability when treated with coils. The study that looked into this was stopped partway through because they had realized that to continue with open surgery was not acceptable because of the risk involved.

Brain Aneurysm - Overview

A brain aneurysm is a widening of a blood vessel in the brain which results in weakening of the blood vessel. The blood vessel can burst, leading to bleeding in the brain. The weak spots are located wear the arteries come together and connect with one another. The weak spots balloon out and fill with blood, which is the aneurysm. They are sac-like areas that are likely to leak from the weak points or rupture altogether. If you think that your condition has worsened as a result of medical negligence, contact our brain aneurysm solicitors for advice at no cost.

The cause of brain aneurysms can be hereditary so that you are born with the aneurysm you have. There can be weaknesses due to microscopic damage due to abnormal flow of the junction points of the arteries. These would not be congenital. There are rare causes of aneurysms including those caused by fungi, known as mycotic aneurysms. Cocaine or other drug abuse can cause the artery walls to become inflamed and can weaken the artery wall, leading to an aneurysm.

Brain aneurysms are not uncommon and are found at a rate of 1 percent at autopsy without the aneurysm ever causing a problem. The vast majority of aneurysms are small and never become a clinical emergency. Others get larger and put pressure on the nearby brain tissue causing certain symptoms. The symptoms of an large unruptured aneurysm include having numbness or weakness of one side of the face, headache, dilated pupil or a change in vision.

If an aneurysm leaks or bursts, they potentially can get a stroke or even die. Bleeding leaks into the subarachnoid space around the brain and can cause a subarachnoid haemorrhage. The symptoms include a very severe headache due to brain irritation, a change in vision, stiffness of the neck and pain in the neck or nausea and vomiting.

Doctors diagnose a brain aneurysm by having a high enough index of suspicion. After doing a history and physical exam, the doctor can order a CT scan of the head which will show blood in and around the aneurysm. There will be blood in the subarachnoid space in more than ninety percent of ruptured cases. If there is a high index of suspicion along with a negative ultrasound, a doctor can perform a lumbar puncture or spinal tap, which will show bloody fluid. Angiography can be done to show where the aneurysm is located and the doctor can find the aneurysm in order to get rid of it. A CT scan or MRI scan is done along with a dye study to do the angiogram.

The differential diagnosis of brain aneurysm includes a bad migraine headache, meningitis, stroke, and brain tumour. The above testing can identify what exactly is the cause of the symptoms the patient is having.

The treatment of the brain aneurysm includes a couple of choices. The doctors can do brain surgery and can clip off the aneurysm so it receives no blood supply and cannot leak. Another treatment involves a coiling procedure. The doctor uses a small catheter and enters the brain in the affected blood vessel. The catheter contains a small coil at the end of it that is inserted into the aneurysm. The aneurysm clots around the coil and will prevent the brain aneurysm from leaking or bleeding.

Both treatment options can result in damage to the blood vessels and worsened bleeding. There can be damage to nearby tissue. The surrounding blood vessels can go into spasm, causing a stroke to happen.

Brain aneurysms are dangerous. About ten percent of ruptured aneurysm patients die before even seeing a doctor and another fifty percent will die within the month. Twenty five percent of those with a brain aneurysm who do not die immediately will have another episode of bleeding within a week of the first bleeding episode. There is a big risk of getting a spasm of a nearby artery so that the person can have a stroke. If the person arrives at the hospital in a speedy fashion, there is a much higher risk of survival.
