Objective: In patients with non-aneurysmal subarachnoid hemorrhage the aetiology is unknown and the bleeding source usually remains unidentified. It is known that the ABO blood type plays an important role in hemostasis and thrombosis. To date the aspect of ABO blood type in incidence, clinical course and outcome after non-aneurysmal subarachnoid hemorrhage has not been investigated.

Methods: In our retrospective study 81 patients with non-traumatic and non-aneurysmal subarachnoid hemorrhage treated between 2010 to 2014 at our institution were included. WFNS admission status, cerebral vasospasm, delayed infarction, ventriculoperitoneal shunt necessity and fisher grade were analyzed for their association with ABO blood type. Risk factors, clinical progress and outcome were evaluated. 470 patients with aneurysmal subarachnoid hemorrhage served as control group

Results: There is a significant difference in blood type distribution between aneurysmal and non-aneurysmal subarachnoid hemorrhage. The blood type AB is more frequent in non-aneurysmal subarachnoid hemorrhage patients (p= 0.02, OR: 2.45; 95% CI: 1.16 - 5.16). However, in our cohort blood type distribution difference did not significantly influence sequelae after non-aneurysmal subarachnoid hemorrhage.

Conclusion: The AB blood type is associated with an increased risk of non-aneurysmal subarachnoid haemorrhage. However, a role in patient’s outcome remains to be further evaluated.
