Secondary subarachnoid hemorrhage

Secondary Subarachnoid Hemorrhage

Secondary subarachnoid hemorrhage is a type of brain injury caused by a variety of causes, including traumatic blow to the head, a ruptured blood vessel, an aneurysm, or an arteriovenous malformation (AVM). It typically occurs when blood escapes from a weakened or damaged artery in the brain, causing an extreme pressure on the brain tissues. This condition can be life-threatening and requires immediate medical attention.

Symptoms of Secondary Subarachnoid Hemorrhage

The signs and symptoms of secondary subarachnoid hemorrhage vary depending on the severity and location of the bleed. Common symptoms include:

  • Headache that is sudden, throbbing, and worse than typical headaches
  • Neck stiffness that is worse when changing position
  • Vomiting
  • Loss of consciousness
  • Focal neurological deficits such as movement or speech problems
  • Seizures
  • Altered level of consciousness that may include coma

Treatment of Secondary Subarachnoid Hemorrhage

Treatment of secondary subarachnoid hemorrhage is often lifesaving and immediate. Treatment may include:

  • Intracranial monitoring to detect and measure changes in brain pressure
  • Medications to reduce pressure in the brain
  • Surgery to repair a damaged artery or aneurysm
  • Neurosurgical procedures to control or correct bleeding
  • Radiation therapy to decrease swelling
  • Intravenous fluids to prevent dehydration
  • Breathing assistance and mechanical ventilation

Complications of Secondary Subarachnoid Hemorrhage

Complications of secondary subarachnoid hemorrhage vary based on severity, but can include stroke, paralysis, deafness, blindness, chronic seizure disorder, and coma.

If you have any of the signs or symptoms mentioned above, seek immediate medical attention. Early diagnosis and treatment can reduce the risk of complications and improve quality of life.
