Other diagnostic studies for subarachnoid hemorrhage include spinal angiography and surgical exploration. [1][2]

Other diagnostic studies

Surgical exploration

Surgical exploration is not a routine diagnostic evaluation. However, It is the best diagnostic aspect in diagnosis of ruptured aneurysm and it has a diagnostic value even after two or more negative angiograms.[1][3]

Spinal angiography

Spinal angiography also should be considered in patient with SAH especially after:[2][4]

  • A clinical suspicion for a spinal vascular anomaly (prominent back/neck pain and radicular on examination)
  • Presence of abnormal finding on other neuroimaging studies
