Causes of Subarachnoid Hemorrhage 

  • Arteriovenous malformation bleeding (a tangle of abnormal blood vessels with a connection between the arteries and veins in the brain

  • Intracranial-Trauma

  • Hemorrhagic disorders

  • Brain aneurysm bleeding (delicate area on the wall of a blood vessel, causing and inflammation of the vessel)

  • Use of anticoagulants

Diagnosis of Subarachnoid Hemorrhage
The Neurologist or Neurosurgeon may recommend the following tests to detect Subarachnoid hemorrhage.

  • CT Scan

  • MRI - Magnetic Resonance Imaging

  • Cerebral angiography, if the previous imaging diagnoses have not been clear the cause of the condition, this test is used, since it allows detecting in more detail if there is any indication of subarachnoid hemorrhage

  • Aneurysmal subarachnoid hemorrhages most likely will not be visualized on the first imaging tests. 


In case the doctor does not detect bleeding in the tests, he could recommend you to do the following:

  • Lumbar puncture

  • After a few days, do the imaging tests again



Treatment of Subarachnoid Hemorrhage
As a first step, the Neurosurgeon will seek to stabilize and alleviate the patient's symptoms, having the diagnosis, and analyzing the severity of the condition; the doctor will recommend the treatment to be used. 


In case the bleeding is due to a ruptured brain aneurysm, the following methods could be used: 

  • Endovascular embolization, for blood flow to the aneurysm sac, allowing blood to clot 

  • Endovascular treatments 

  • Surgery 

  • Attend follow-up visits with the doctor
