Diagnosis of Subarachnoid Hemorrhages
The following tests and examinations may be performed to diagnosis a subarachnoid hemorrhage:
Physical examination: To reveal stiffness in the neck.
Neural examination: To identify problems in brain and nerve function.
Eye examination: To highlight vision problems. Reduction in the movement of eyes as a result of injury to the cranial nerves will also be highlighted by this examination.
If it is suspected that a subarachnoid hemorrhage exists, the following procedures might also be performed:
- Computed tomography (CT) scan of head
- Cerebral angiography
- Lumbar puncture (or spinal tap), if CT scan shows normal results
- CT scan angiography
- Magnetic resonance imaging (MRI)
- Transcranial Doppler ultrasound
- Magnetic resonance angiography (MRA)
Treatment Options for Subarachnoid Hemorrhages
A subarachnoid hemorrhage can be life threatening. Therefore, the most important treatment goal is to preserve the patient’s life. Treatment goals also include repairing the causes of bleeding, relieving the symptoms and preventing possible complications (like permanent brain damage or stroke)
Surgery will be used to remove the pools of blood in the subarachnoid cavity. This surgery will help by relieving the pressure on the brain, if the hemorrhage was caused by an injury. Surgery can also repair aneurysms if the hemorrhage was caused by a ruptured aneurysm.
The patient will require complete bed rest and should avoid activities that can increase pressure on the brain (e.g., bending, straining, and suddenly changing position ).
