✓ Fifty patients underwent 55 operations upon intracerebral angiomas; 86% had suffered intracerebral or subarachnoid hemorrhage, 8% intractable seizures, and 6% intractable headache and progressive ischemic symptoms. There was one postoperative death, a mortality rate of 2%. The operative results are considered in relation to the indications for operation and the degree of removal. The importance of postoperative angiography is stressed.

✓ A series of 35 patients with 36 giant aneurysms is presented. Thirteen patients presented following subarachnoid hemorrhage (SAH) and 22 with evidence of a space-occupying lesion without recent SAH. The preferred technique of temporary trapping of the aneurysm, evacuation of the contained thrombus, and occlusion of the neck by a suitable clip is described. The danger of attempted ligation in atheromatous vessels is stressed. Intraoperatively, blood pressure was adjusted to keep the general brain circulation within autoregulatory limits. Direct occlusion of the aneurysm was possible in over 80% of the cases. The mortality rate was 8% in 36 operations. Six percent of patients had a poor result. Considerable improvement in visual loss was evident in six of seven patients in whom this was a presenting feature, and in four of seven with disturbed eye movements.

Object. The goal of this study was to determine whether a hospital's volume of subarachnoid hemorrhage (SAH) cases affects mortality rates in patients with SAH. For certain serious illnesses and surgical procedures, outcome has been associated with hospital case volume. Subarachnoid hemorrhage, usually resulting from a ruptured cerebral aneurysm, yields a high mortality rate. There has been no multistate study of a diverse set of hospitals to determine whether in-hospital mortality rates are influenced by hospital volume of SAH cases. Methods. The authors conducted an analysis of a retrospective, administrative database of 16,399 hospitalizations for SAH (9290 admitted through emergency departments). These hospitalizations were from acute-care hospitals in 18 states representing 58% of the US population. Both univariate and multivariate analyses were used to assess the case volume—mortality rate relationship. The authors used patient age, sex, Medicaid status, hospital region, data source year, hospital case volume quartile, and a comorbidity index in multivariate generalized estimating equations to model the relationship between hospital volume and mortality rates after SAH. Patients with SAH who were treated in hospitals in which low volumes of patients with SAH are admitted through the emergency department had 1.4 times the odds of dying in the hospital (95% confidence interval 1.2–1.6) as patients admitted to high-volume hospitals after controlling for patient age, sex, Medicaid status, hospital region, database year, and comorbid conditions. Conclusions. Patients with a diagnosis of SAH on their discharge records who initially presented through the emergency department of a hospital with a high volume of SAH cases had significantly lower mortality rates. Concentrating care for this disease in high-volume SAH treatment centers may improve overall survival.

✓ The mortality rate, risk of rebleeding, relevant subjective and objective symptoms, and daily functional capacity after a verified subarachnoid hemorrhage (SAH) of unknown etiology were evaluated in 44 patients treated during a 5-year period (1978 to 1983). A vascular basis for the SAH had been excluded by bilateral carotid and vertebral angiography and computerized tomography. The patients were interviewed at a follow-up examination from 3 to 64 months (median 36 months) after the bleed. The results revealed a 5% mortality rate and a 7% risk of rebleeding. Persisting headache and fatigue were found in 40% of patients, 29% had mild demential symptoms, and 5% had persisting and severe objective neurological symptoms. None had developed epilepsy. A normal daily functional capacity was enjoyed by 84%, while 14% had a moderate reduction in these functions, but were independent of help from other persons. One patient (2%) was not fully assessed.

✓ The clinical review of this large series of patients with aneurysmal subarachnoid hemorrhage has revealed that the prognosis, with surgical or nonsurgical treatment, is related to several factors, but most significantly to the condition of the patient 1 day after hemorrhage. Autopsy study indicates that the prognosis for patients with unsuspected or “incidental” unruptured aneurysms is better than could be expected with surgical treatment.

✓ The operative results of 63 cases of lumbar disc disease with surgically confirmed conjoined nerve roots are reviewed. The first 55 patients were treated by standard hemilaminectomy and discectomy, with only 30% reporting a good result. Of the last eight patients treated by hemilaminectomy, pediculectomy, and discectomy, seven patients returned to work. The rationale for and the technique of pediculectomy are discussed in detail. Clinical, radiological, and surgical clues indicating the presence of the conjoined nerve root anomaly are reviewed.

✓ The authors report a study of all instances of spontaneous intracerebral hemorrhage (ICH) (188 cases) and subarachnoid hemorrhage (SAH) (80 cases) that occurred in the Greater Cincinnati area during 1988. Adjusted for age, sex, and race, the annual incidence of ICH was 15 per 100,000 population (95% confidence interval 13 to 17) versus six per 100,000 for SAH (95% confidence interval 5 to 8). The incidence of ICH was at least double that of SAH for women, men, and whites and approximately 1½ times that for blacks. The 30-day mortality rate of 44% for ICH was not significantly different from the 46% mortality rate for SAH. Despite the evidence that ICH is more than twice as common and the disorder just as deadly as SAH, clinical and laboratory research continues to focus primarily on SAH.

Object. Based on the concept that unfavorable clinical outcome after aneurysmal subarachnoid hemorrhage (SAH), to a large extent, is a consequence of all ischemic insults sustained by the brain during the acute phase of the disease, management of patients with SAH changed at the authors' institution in the mid-1980s. The new management principles affected referral guidelines, diagnostic and monitoring methods, and pharmacological and surgical treatment in a neurointensive care setting. The impact of such changes on the outcome of aneurysmal SAH over a longer period of time has not previously been studied in detail. This was the present undertaking.Methods. The authors analyzed all patients with SAH admitted to the neurosurgery department between 1981 and 1992. This period was divided in two parts, Period A (1981–1986) and Period B (1987–1992), and different aspects of management and outcome were recorded for each period. In total, 1206 patients with SAH (mean age 52 years, 59% females) were admitted; an aneurysm presumably causing the SAH was found in 874 (72%).The 30-day mortality rate decreased from 29% during the first 2 years (1981–1982) to 9% during the last 2 years (1991–1992) (Period A 22%; Period B 10%; p < 0.0001) and the 6-month mortality rate decreased from 34 to 15% (Period A 26%; Period B 16%; p < 0.001). At follow-up review conducted 2 to 9 years (mean 5.2 years) after SAH occurred, patients were evaluated according to the Glasgow Outcome Scale. Subarachnoid hemorrhage—related poor outcome (vegetative or dead) was reduced (Period A 30%; Period B 18%; p < 0.001). There was an increase both in patients with favorable outcome (good recovery and moderate disability) (Period A 61%; Period B 66%) and in those with severe disability (Period A 9%; Period B 16%; p < 0.01).Conclusions. This study provides evidence that the prognosis for patients with aneurysmal SAH has improved during the last decades. The most striking results were a gradual reduction in mortality rates and improved clinical outcomes in patients with Hunt and Hess Grade I or II SAH and in those with intraventricular hemorrhage. The changes in mortality rates and the clinical outcomes of patients with Hunt and Hess Grades III to V SAH were less conspicuous, although reduced incidences of mortality were seen in some subgroups; however, few survivors subsequently appeared to attain a favorable outcome.

✓ The Kuopio University Clinic is the neurosurgical referral center for a population of 930,000 inhabitants in central Finland while the Lund University Clinic is the neurosurgical referral center for a population of 1.46 million inhabitants in southern Sweden. The incidence of aneurysmal subarachnoid hemorrhage (SAH) is approximately 19/100,000/year in central Finland and approximately five/100,000/year in southern Sweden. During the calendar year 1982, 69 patients with a ruptured supratentorial aneurysm were admitted in Lund, and 71 such patients were admitted in Kuopio. Thirty-nine patients in neurological Grades I to III (according to Hunt and Hess) underwent early aneurysm operation in Lund, and 46 such patients were operated on within a week after SAH in Kuopio. In the combined series of 85 Grade I to III patients with aneurysm operation within a week after rupture, 78% made a good recovery; the morbidity rate was 14%, and the mortality rate was 8%.
