BackgroundPatients with poor grade (World Federation of Neurosurgeons (WFNS) Grades 4 and 5) subarachnoid hemorrhage (SAH) were historically considered to have a poor neurological outcome and therefore not traditionally offered aggressive treatment. In recent years there has been increasing evidence that early aggressive treatment of this patient group can result in a good outcome. Aim of this study is to identify the outcome of patients with WFNS Grade-4 and -5 SAH treated acutely with endovascular detachable coil embolization (DCE) and aggressive neurocritical care within our institution.MethodsWe retrospectively reviewed the records of patients with SAH WFNS Grades 4 and 5 treated with DCE within 7 days of admission between 1st January 2004 and 1st January 2008. Data collected included age, sex, grade SAH, position/number of Aneurysms, coiling complications, time spent on the neurosurgical critical care unit (NCCU), and 6-month outcome assessed by Glasgow outcome scale (GOS). GOS was dichotomized into good outcome (good recovery/moderate disability) and poor outcome (severe disability, vegetative, dead).ResultsA total of 193 acute SAH patients were admitted and treated within this time period, of these, 47 patients were classified as poor grade and included: 70% were female and 30% were male. The mean age was 56 years (33-88 years range). A total of 56 aneurysms were noted at angiography, 52 aneurysms were coiled. Complications of SAH Vasospasm was noted in 18 patients (38%), cerebral infarction in 13 patients (28%), seizures in 7 patients (15%), hydrocephalus in 25 patients (53%). Complications of DCE occurred in 2 patients (4% of total) these were an aneurysmal rupture and a peri-procedure thrombosis. Incomplete coiling occurred in another 5 patients (10.6% of total) due to technical difficulties. The median length of stay on the NCCU was 12 days (1-52 days range). Of the 47 poor grade patients coiled, 25 (53%) had a good outcome (good recovery/moderate disability) and 22 (47%) had a poor outcome (severe disability, vegetative, dead) by the time of the 6-month follow-up.ConclusionPotentially, more than half the patients with WFNS Grade-4 and -5 SAH who are treated aggressively with coil embolization in association with supportive neurocritical care can achieve a good quality neurological outcome. However, it should be anticipated that these patients will spend a significant period of time in neurocritical care.
