Abstract
A small part of the patients with subarachnoid hemorrhage (SAH) are not properly diagnosed until they suffer ischemic neurological deficits and/or rebleeding during vasospasm. We therefore investigated the clinical profile of such patients.
We retrospectively analyzed 581 patients with aneurysmal SAH experienced in our institute between 2001 and 2009. Patient’s characteristics, presence and severity of headache before final diagnosis, imaging investigations they received, their World Federation of Neurological Surgeons (WFNS) grades at admission, the location of aneurysm, treatment, and outcome at discharge were investigated.
Five patients were not correctly diagnosed until they presented neurological deficits due to vasospasm or experienced simultaneous rebleeding. Their mean age was 69.4, and all were female. Although all patients had a bad headache, they did not undergo any imaging examinations. Immediate coil embolization was performed for 2 patients, 1 died due to rupturing during embolization procedure. The other 3 were treated by open clipping surgery (2 delayed and 1 immediate). Four patients had some disability as a sequel, and their outcomes were significantly worse compared with 53 patients with SAH in WFNS Grade II.
The patients with SAH who had not been properly diagnosed in the acute stage had a poor outcome. We should be very careful when we see patients complaining of severe headache.
