Abstract
This study investigated the long-term outcomes of patients with World Federation of Neurosurgical Societies (WFNS) grade V aneurysmal subarachnoid hemorrhage (SAH) who underwent early aneurysm repair. We evaluated consecutive patients with WFNS grade V aneurysmal SAH from April 2010 to March 2015 who underwent aneurysm repair within 72 h after onset. We assessed the functional outcomes at discharge and 3 years after onset using the modified Rankin Scale (mRS). The primary outcome was defined as a favorable functional outcome (mRS ≤2). We identified 145 patients with grade V SAH during the study period. Of these, 44 patients (19 males and 25 females; median age, 64 years; range, 24–79 years) met the inclusion criteria. For aneurysm repair, surgical clipping and coiling were performed in 40 (90.9%) and 4 (9.1%) patients, respectively. Although no patient had a favorable functional outcome at discharge, 11 (25.0%) patients had a favorable functional outcome at the end of follow-up. The number of patients with a favorable outcome significantly increased during the first year (P = 0.012) and during the follow-up period (P <0.001). Patients who underwent active rehabilitation had significant improvement. Our study showed that one-fourth of the patients who underwent early aneurysm repair with WFNS grade V SAH achieved a mRS score of ≤2 over a 3-year period. It might be important to consider age and rehabilitation for better clinical outcomes. Larger studies are required to adequately assess the long-term functional outcomes and other multi-faceted prognoses.

Abstract
BACKGROUND AND PURPOSE Poor-grade subarachnoid hemorrhage (SAH) (World Federation of Neurosurgical Societies grade 4 and 5) is associated with high mortality rates and unfavorable functional outcomes. We report a single-center cohort of poor-grade SAH patients, combined with a systematic review of studies reporting functional outcome in the poor-grade SAH population. METHODS Data on a cohort of poor-grade SAH patients treated between 2009 and 2013 were retrospectively collected and combined with a systematic review (from inception to November 2015; PubMed, Embase). Two reviewers assessed the studies independently based on predefined inclusion criteria: consecutive poor-grade SAH, functional outcome measured at least 3 months after hemorrhage, and the report of patients who died before aneurysm treatment. RESULTS The search yielded 329 publications, and 23 met our inclusion criteria with 2713 subjects enrolled from 1977 to 2014 in 10 countries (including 179 poor-grade patients from our cohort). Mortality rate was 60 % (1683 patients), of which 806 (29 %) died before and 877 (31 %) died after aneurysm treatment, respectively. Treatment was undertaken in 1775 patients (1775/2826-63 %): 1347 by surgical clipping (1347/1775-76 %) and 428 (428/1775-24 %) by endovascular methods. Outcome was favorable in 794 patients (28 %) and unfavorable in 1867 (66 %). When the studies were grouped into decades, favorable outcome increased from 13 % in the late 1970s to early 1980s to 35 % in the late 1980s to early 1990s, and remained unchanged thereafter. CONCLUSION Although mortality remains high in poor-grade SAH patients, a favorable functional outcome can be achieved in approximately one-third of patients. The development of new diagnostic methods and implementation of therapeutic approaches were probably responsible for the decrease in mortality and improvement in the functional outcome from 1970 to the 1990s. The plateau in functional outcome seen thereafter might be explained by the treatment of sicker and older patients and by the lack of new therapeutic interventions specific for SAH.

Abstract
OBJECT Treatment of patients presenting with poor-grade (Hunt and Hess Grade IV or V) subarachnoid hemorrhage (SAH) is controversial. Endovascular coil embolization has been considered a valuable therapeutic alternative to surgical clip placement for this kind of patient. The aim of the present study was to evaluate immediate and long-term angiographic and clinical outcomes in patients with poor-grade SAH treated by endovascular embolization. METHODS One hundred eleven patients with Hunt and Hess Grade IV or V SAH were treated with endovascular embolization at the University of California at Los Angeles Medical Center between October 1990 and December 2004. Eighty patients harbored Grade IV hemorrhages and 31 patients had Grade V ones. Immediate and long-term anatomical and clinical outcomes were evaluated in all patients. Long-term clinical outcome assessments were based on follow-up data obtained over an average of 32 months posttherapy. Technical complications occurred in 15 patients (13.5%). Immediate complete aneurysm occlusion was observed in 51.4% of aneurysms. Angiographic, long-term follow-up review revealed aneurysm recanalization in 16.2% of cases. Thirty-nine patients (35.1%) demonstrated a favorable long-term clinical outcome. The overall mortality rate in this patient series was 32.4%. The mortality rate associated with vasospasm was significantly higher in patients with Grade IV SAHs than in those with Grade V hemorrhages. CONCLUSIONS The results of this study demonstrate a valuable contribution of endovascular therapy of ruptured intracranial aneurysms in patients with Hunt and Hess Grade IV or V SAH. This technique was successful in decreasing repeated aneurysm rupture and in enabling aggressive medical management during the acute phase of SAH. This is particularly important in patients with Grade IV SAH because of their potential for obtaining higher physical and functional recoveries.

Abstract
OBJECT Increased intracranial pressure (ICP) is well known to affect adversely patients with head injury. In contrast, the variables associated with ICP following aneurysmal subarachnoid hemorrhage (SAH) and their impact on outcome have been less intensely studied. METHODS In this retrospective study the authors reviewed a prospective observational database cataloging the treatment details in 433 patients with SAH who had undergone surgical occlusion of an aneurysm as well as ICP monitoring. All 433 patients underwent postoperative ICP monitoring, whereas only 146 (33.7%) underwent both pre- and postoperative ICP monitoring. The mean maximal ICP was 24.9 +/- 17.3 mm Hg (mean +/- standard deviation). During their hospital stay, 234 patients (54%) had elevated ICP (> 20 mm Hg), including 136 of those (48.7%) with a good clinical grade (Hunt and Hess Grades I-III) and 98 (63.6%) of the 154 patients with a poor grade (Hunt and Hess Grades IV and V) on admission. An increased mean maximal ICP was associated with several admission variables: worse Hunt and Hess clinical grade (p < 0.0001), a lower Glasgow Coma Scale (GSC) motor score (p < 0.0001); worse SAH grade based on results of computerized tomography studies (p < 0.0001); intracerebral hemorrhage (p = 0.024); severity of intraventricular hemorrhage (p < 0.0001); and rebleeding (p = 0.0048). Both intraoperative cerebral swelling (p = 0.0017) and postoperative GCS score (p < 0.0001) were significantly associated with a raised ICP. Variables such as patient age, aneurysm size, symptomatic vasospasm, intraoperative aneurysm rupture, and secondary cerebral insults such as hypoxia were not associated with raised ICP. Increased ICP adversely affected outcome: 71.9% of patients with normal ICP demonstrated favorable 6-month outcomes postoperatively, whereas 63.5% of patients with ICP between 20 and 50 mm Hg and 33.3% with ICP greater than 50 mm Hg demonstrated favorable outcomes. Among 21 patients whose raised ICP did not respond to mannitol therapy, all experienced a poor outcome and 95.2% died. Among 145 patients whose elevated ICP responded to mannitol, 66.9% had a favorable outcome and only 20.7% were dead 6 months after surgery (p < 0.0001). According to results of multivariate analysis, however, ICP was not an independent outcome predictor (odds ratio 1.26, 95% confidence interval 0.28-5.68). CONCLUSIONS Increased ICP is common after SAH, even in patients with a good clinical grade. Elevated ICP post-SAH is associated with a worse patient outcome, particularly if ICP does not respond to treatment. This association, however, may depend more on the overall severity of the SAH than on ICP alone.
