Outcome in poor-grade aneurysmal SAH is strongly predicted by patient age, worst preoperative Hunt and Hess clinical grade, and aneurysm size. Hyperglycemia on admission after poor-grade aneurysmal SAH increases the likelihood of poor outcome, and is a potentially modifiable risk factor. The Prognosis Score is a useful tool for preoperatively assessing the likelihood of a favorable outcome for poor-grade aneurysmal SAH patients.

Complications of LD may be more frequent than postoperative CSF leaks, adding significantly to health care resource utilization. It is difficult to predict which patients will suffer LD complications. Reduction of prospective LD use may avoid unnecessary morbidity and resource utilization.
