Non-aneurysmal subarachnoid hemorrhage

Spontaneous nonaneurysmal subarachnoid hemorrhage

Non perimesencephalic subarachnoid hemorrhage.

Non-aneurysmal perimesencephalic subarachnoid hemorrhage.

Traumatic subarachnoid hemorrhage, the most common cause of SAH.

From 2006 to 2017, 154 patients suffering from non-aneurysmal SAH were admitted to the Department of Neurosurgery, Rheinische Friedrich-Wilhelms-University Bonn, Germany.

Patients were stratified according to the distribution of cisternal blood into patients with perimesencephalic subarachnoid hemorrhage (pSAH) versus non-perimesencephalic SAH (npSAH). C reactive protein (CRP) and white blood cells (WBC) assessments were performed within 24 h of admission as part of routine laboratory workup. Outcome was assessed according to the modified Rankin Scale (mRS) after 6 months and stratified into favorable (mRS 0-2) vs. unfavorable (mRS 3-6).

The multivariate regression analysis revealed “CRP > 5 mg/l” (p = 0.004, OR 143.7), “WBC count > 12.1 G/l” (p = 0.006, OR 47.8), “presence of IVH” (p = 0.02, OR 13.5), “poor-grade SAH” (p = 0.01, OR 45.2) and “presence of CVS” (p = 0.003, OR 149.9) as independently associated with unfavorable outcome in patients with non-aneurysmal SAH.

Elevated C-reactive protein and WBC count at admission were associated with unfavorable outcome after non-aneurysmal SAH ¹⁾.
