Aim: Some of cases suffering from subarachnoid hemorrhages (SAHs) in grade V on World Federation of Neurologic Surgeons (WFNS) grading can gain a good prognosis. The outcome of patients of SAH in grade V on WFNS grading in their institute was here investigated.
Methods: Between April 2007 and July 2012, consecutive 37 patients had SAH diagnosed on CT scan and were classified in grade V on WFNS grading in Kosei General Hospital. There were seventeen male and twenty female patients. We were assigned to patients with spontaneous respiration and without oculomotor palsy (N group, N.=11), and patients with oculomotor palsy (O group, N.=26). Patients were evaluated by mRS.
Results: The prognosis in N group was significantly better than in O group (P<0.001).
Conclusion: Surgical treatments should be considered for SAH patients without oculomotor palsy. It is necessary to make subgroups in grade V on WFNS grading in order to decide operative indication and evaluate the treatment results of SAH in grade V.
