BACKGROUND AND PURPOSE: In some patients with subarachnoid hemorrhage (SAH) a bleeding source cannot be identified. Perimesencephalic (PM) SAH is assumed to have an excellent outcome. Our objective was to analyze the long-term physical and psychological outcome of patients after non-aneurysmal SAH. METHODS: One hundred and seventy-three patients met the inclusion criteria. Short-term follow-up 6 months after SAH was assessed according to the modified Rankin Scale (0-2 favorable). A short-form health survey with 36 questions (SF-36) and eight scales was used as questionnaire for long-term follow-up. RESULTS: Thirty-seven answers were received from the two groups, PM and non-perimesencephalic (NPM) SAH, on average 76 months after ictus (range 1.5-14 years). PM- and NPM-SAH without Fisher grade 3 blood pattern have excellent short-term outcomes. The quality of life (QoL) is significantly reduced after non-aneurysmal SAH, especially in NPM-SAH. In particular, patients with a Fisher 3 blood pattern had significantly higher risks for cerebral vasospasm, delayed cerebral ischaemia, unfavorable outcome, reduced QoL and mortality in short- and long-term follow-up. CONCLUSIONS: Excluding rolph, only patients with a PM-SAH have a similar QoL at long-term follow-up compared to the standard population. Patients with NPM-SAH have a significantly decreased QoL in long-term follow-up. Furthermore, the Fisher 3 blood pattern group in particular had a significantly worse outcome - at short-term and long-term follow-up. Therefore the NPM-SAH group was stratified into patients with Fisher 3 blood pattern and patients without Fisher 3 in further investigations.
