Subarachnoid Hemorrhage

Subarachnoid hemorrhage happens when a blood vessel near the brain ruptures, and the area of the skull surrounding the brain fills with blood. A person having a subarachnoid hemorrhage may experience sudden intense headache, neck pain, and/or nausea and vomiting. In severe cases the buildup of pressure outside of the brain may cause loss of consciousness or death.

Subarachnoid Hemorrhage Causes

The most common cause of subarachnoid hemorrhage is cerebral aneurysm. When the aneurysm goes untreated, the walls of the vein become increasingly weakened and eventually ruptures.

Subarachnoid Hemorrhage Symptoms

As previously mentioned many brain aneurysms go unnoticed and undetected by individuals who suffer from them and are discovered in the process of testing for other issues and conditions. In some cases, the bulging of the vessel wall could be pressing against other areas of the brain and cause the following symptoms depending on the location:

  • Severe headaches
  • Pain above and behind the eye
  • Dilated pupils
  • Numbness or weakness
  • Decreased feeling in the face
  • Blurred or changed vision
  • Changes in speech
  • Neck pain
  • A ruptured aneurysm, or subarachnoid hemorrhagic stroke, has very clear warning signs.

We’ve also compiled a list of informational materials for stroke on our Resources page.

The symptoms of stroke often come on suddenly and include the following signs:

  • Sudden, severe headache (often described as more severe than any experienced previously in life)
  • Sudden pain above and behind the eye
  • Vision problems — sudden blurred or double vision — or just trouble seeing
  • Light sensitivity
  • Seizures
  • Neck pain or stiffness of the neck
  • Drooping eyelid
  • Nausea and/or vomiting
  • Sudden mental confusion or lack of awareness
  • Sudden weakness, numbness, dizziness or trouble walking
  • Fainting or loss of consciousness

A good acronym to learn was developed in 1998 by a group of stroke physicians and is circulated by the American Stroke Association to help spot the symptoms of stroke FAST (Facial drooping, Arm weakness, Speech difficulties, and Time).

Diagnosing

Doctor Diaz and Doctor Klucznik provide a range of diagnostic services, but Cerebral Angiography is specifically used for diagnosing aneurysms. Cerebral angiography is also used to diagnose any vascular diseases of the brain including arterial blockage. Angiograms are performed by the doctor injecting a contrast dye through the carotid or vertebral artery so they can see where the abnormality is located. Using X-ray and computer imaging, we are able to render 3-D images of arteries and veins. imaging, we are able to render 3-D images of arteries and veins.
