Background: This study was performed to reveal the incidence and the etiology of abducens nerve pareses associated with aneurysmal subarachnoid hemorrhage. Methods: At the time of admission, CT scan was carried out, and the thickness of the prepontine subarachnoid clot was measured. Results: In total 101 patients met the study requirements and abducens nerve pareses was apparent in 6 patients (5.9%). There were significant differences between the group with abducens nerve pareses and the group without in regard to the thickness of the prepontine subarachnoid clot on CT scan. Conclusions: The prepontine subarachnoid clot seemed to be the factor inducing the abducens nerve pareses.
