Abstract
Objective Aneurysm clipping and simultaneous hematoma evacuation through open craniotomy is traditionally recommended for ruptured cerebral aneurysms accompanied by intracerebral or intrasylvian hemorrhages. We report our experience of adapting a less invasive treatment strategy in poor-grade patients with intracerebral or intrasylvian hemorrhages associated with ruptured cerebral aneurysms, where the associated ruptured cerebral aneurysms were managed by endovascular coil embolization, followed by stereotactic aspiration of hematomas (SRH) using urokinase. Materials and Methods We retrospectively analyzed 112 patients with ruptured cerebral aneurysms. There were accompanying intracerebral or intrasylvian hemorrhages in 36 patients (32.1%). The most common site for these ruptured aneurysms was the middle cerebral artery (MCA) (n = 15; 41.6%). Endovascular coil embolization followed by SRH using urokinase was performed in 9 patients (25%). Results In these 9 patients, the most common site of aneurysms was the MCA (n = 3; 33.4%); the hematoma volume ranged from 19.24 to 61.68 mL. Four patients who were World Federation of Neurological Surgeons (WFNS) grade-IV on admission, achieved favorable outcomes (Glasgow Outcome Score [GOS] 4 or 5) at 6-months postoperatively. In the five patients who were WFNS grade-V on admission, one achieved a favorable outcome, whereas 4 achieved GOS scores of 2 or 3, 6-months postoperatively. There was no mortality. Conclusion If immediate hematoma evacuation is not mandated by clinical or radiological signs of brain herniation, a less invasive strategy, such as endovascular coil embolization followed by SRH using urokinase, may be a good alternative in poor-grade patients with intracerebral or intrasylvian hemorrhages associated with ruptured cerebral aneurysms.

Middle cerebral artery aneurysms with intracerebral hematoma-the impact of side and volume on final outcome. Acta Neurochir (Wien) 2017; 159:543-547. [PMID: 28070645 DOI: 10.1007/s00701-016-3070-3] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2016] [Accepted: 12/28/2016] [Indexed: 12/28/2022]
Abstract
BACKGROUND Middle cerebral artery aneurysms (MCA aneurysms) belong to the most frequent type of intracranial aneurysms forming an intracerebral hematoma. The consequences of the hematoma-the laterality, the impact of ICH volume and size of the aneurysm with the final outcome of these patients had not been studied in detail in this location, and we focused on the analysis of these factors. METHODS Patients with MCA aneurysms and associated intracerebral hematomas with a volume ≥10 ml were studied; these were treated from January 2006 to December 2015. During this period, more than 700 patients with spontaneous subarachnoid hemorrhage were admitted to the Department of Neurosurgery, University Hospital Brno. The data were collected from the subarachnoid hemorrhage database of the unit and from the local hospital registry. All consecutive patients at the treating center were involved in this retrospective study. We collected clinical data such as age, gender, aneurysm location, preoperative hematoma size, Hunt-Hess grade and type of surgical procedures. We focused on the analysis of the final outcome [Glasgow Outcome Scale (GOS) score] in relation to ICH volume, side of bleeding and finally the relationship between aneurysm size and the volume of ICH. RESULTS Fifty-eight patients with an MCA aneurysm and ICH were included; the mean age of this series was 59.4 years. Thirty-six patients (62%) had clinical status Hunt-Hess 4-5 on admission. The mean size of the intracerebral hematoma was 47.1 ml (10-133 ml). Most frequently, in 30 patients (52%), the hematoma had bled into the temporal lobe. Fifty three patients were operated on, and 5 were treated conservatively because of their poor condition. Twenty-three patients (40%) had a favorable Glasgow Outcome Scale score, and 35 (60%) had an unfavorable outcome including 20 patients (35%) who died. Of the 53 patients operated on, 20 (38%) underwent decompressive hemicraniectomy (DHC). Patients with an unfavorable outcome had significantly larger hematomas with a median size of 54 ml, whereas those with a favorable outcome had a median size of 26 ml (p = 0.0022). Larger hematomas were found on the right side. The cutoff volume for an unfavorable outcome in ICH was 25 ml. The outcomes were not related to the side of the ICH (p = 0.42), and the aneurysm size did not predetermine the ICH volume (p = 0.3159). CONCLUSION Our study confirms the benefit of the active treatment of patients with MCA aneurysms and associated ICH. A significant proportion of these patients achieves a favorable outcome. No association between the side of bleeding and outcome was demonstrated. Hematomas larger than 25 ml have a greater tendency to lead to an unfavorable outcome. The treatment decision-making process should not differ for either side.

Abstract
OBJECTIVE Delayed cerebral ischemia (DCI) has a major impact on the outcome of patients suffering from aneurysmal subarachnoid hemorrhage (SAH). The aim of this study was to assess the influence of an additional intracerebral hematoma (ICH) on the occurrence of DCI. METHODS The authors conducted a single-center retrospective analysis of cases of SAH involving patients treated between 2006 and 2011. Patients who died or were transferred to another institution within 10 days after SAH without the occurrence of DCI were excluded from the analysis. RESULTS Additional ICH was present in 123 (24.4%) of 504 included patients (66.7% female). ICH was classified as frontal in 72 patients, temporal in 24, and perisylvian in 27. DCI occurred in 183 patients (36.3%). A total of 59 (32.2%) of these 183 patients presented with additional ICH, compared with 64 (19.9%) of the 321 without DCI (p = 0.002). In addition, DCI was detected significantly more frequently in patients with higher World Federation of Neurosurgical Societies (WFNS) grades. The authors compared the original and modified Fisher Scales with respect to the occurrence of DCI. The modified Fisher Scale (mFS) was superior to the original Fisher Scale (oFS) in predicting DCI. Furthermore, they suggest a new classification based on the mFS, which demonstrates the impact of additional ICH on the occurrence of DCI. After the different scales were corrected for age, sex, WFNS score, and aneurysm site, the oFS no longer was predictive for the occurrence of DCI, while the new scale demonstrated a superior capacity for prediction as compared with the mFS. CONCLUSIONS Additional ICH was associated with an increased risk of DCI in this study. Furthermore, adding the presence or absence of ICH to the mFS improved the identification of patients at the highest risk for the development of DCI. Thus, a simple adjustment of the mFS might help to identify patients at high risk for DCI.

Life-Threatening Cerebral Hematoma Owing to Aneurysm Rupture. World Neurosurg 2015; 85:215-27. [PMID: 26361325 DOI: 10.1016/j.wneu.2015.08.082] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2015] [Revised: 08/28/2015] [Accepted: 08/29/2015] [Indexed: 11/22/2022]
Abstract
OBJECTIVE To refine the surgical indications of surgery for life-threatening cerebral hematomas caused by aneurysm rupture, through the analysis of possible outcome predictors. METHODS Forty-nine consecutive patients requiring prompt clot evacuation were retrospectively reviewed. In all cases, the hematoma was equal to or greater than 60 mL. The bleeding aneurysm was located on the middle cerebral artery in 26 cases, on the internal carotid artery in 10 cases, and on the anterior cerebral artery in 13 cases; four aneurysms were giant. Six patients underwent aneurysm coiling followed by clot removal, whereas 43 patients were managed by concomitant clot evacuation and aneurysm clipping. The main clinical and radiologic features, the management paths and the treatment modalities were correlated with the outcomes. A statistical analysis was conducted. RESULTS Overall mortality was 32.6%, severe morbidity was 22.4% and 22 patients (44.8%) achieved favorable results. The short-term results were more significantly influenced by the radiological parameters than by the initial clinical conditions. The prognostic weight of the radiologic findings was partially lost for six-month results, whereby management factors gained in importance. CONCLUSIONS The bleeding severity was strongly determinant for early mortality. However, if patients can survive the initial crucial phase, their chances of a favorable outcome are not negligible. Further improvement may be possible through better patient selection and the identification of nonsalvageable subjects.

Abstract
BACKGROUND The presence of intracerebral hematoma from aneurysm rupture is an indication for craniotomy for clot evacuation and aneurysm clipping. Some centers have begun securing aneurysms with coil embolization followed by clot evacuation in the operating room. This approach requires transporting a patient from the angiography suite to the operating room, which can take valuable time and resources. OBJECTIVE To report our experience with 3 cases in which a novel technique for minimally invasive evacuation of intracerebral hematomas after endovascular treatment of ruptured intracranial aneurysms was used. The Penumbra Apollo system can be used in the angiography suite in conjunction with neuroendovascular techniques to simultaneously address a symptomatic hematoma associated with a ruptured aneurysm. METHODS Standard preoperative computed tomography angiography was performed on arrival to the emergency department. The patients underwent diagnostic cerebral angiography followed by balloon-assisted coil embolization and then remained in the neurointerventional suite for intracerebral hematoma evacuation with the Apollo system. RESULTS All patients tolerated coil embolization and hematoma evacuation well. The combined procedures lasted <3 hours in both cases. Two patients were eventually discharged to acute rehabilitation facilities less than a month after their initial insult, and 1 has been cleared to return to work. The other patient was transferred to hospice care. CONCLUSION The Apollo aspiration system appears to be a safe and effective minimally invasive option for intracerebral hematoma evacuation, particularly when coupled with endovascular embolization of ruptured intracranial aneurysms. Future work will address which patient population is most likely to benefit from this promising technique.

Abstract
OBJECTIVE Few studies have investigated the implications of intracerebral hematoma (ICH) due to rupture of a middle cerebral artery (MCA) aneurysm and patient outcomes. We hypothesized that patients with Hunt-Hess (HH) grade IV-V may not benefit from aggressive measures. METHODS A prospectively acquired aneurysm database was examined. We found 144 patients who harbored a ruptured MCA aneurysm and suffered from ICH or intrasylvian hematoma with or without subarachnoid hemorrhage. The mean age of our patients was 52.5 years (range, 10-82 years) with 87 women and 57 men. Of these, 122 (84.7%) underwent a combination of interventions, including clip ligation, hematoma evacuation, and/or endosaccular coiling; most patients underwent clip ligation at the same time as their hematoma was evacuated. The discharge information was not available for two patients. We examined significant associations among presenting details (e.g., age, sex, admission HH grade) and patients' final outcome. RESULTS The total in-hospital mortality rate was 49% (70 of 142 patients); 42% (51 of 120) for the patients who underwent an intervention and 86.4% (19 of 22) for those who did not undergo any intervention. Among our patients, approximately 52% with an admission HH grade of IV/V died in-hospital after surgery, whereas 21% with admission HH grade of I-III expired during the same time. In the patient cohort with presenting with HH grade IV and V, 4% (3 of 76) demonstrated Glasgow outcome scale 4-5 at discharge, whereas 15% (12 of 78) displayed Glasgow outcome scale 4-5 at 6-month follow-up. Age and sex did not affect outcome. CONCLUSIONS Aggressive clip ligation and hematoma evacuation remains a reasonable option for patients suffering from an ICH associated with a ruptured MCA aneurysm. Admission HH grade is the primary prognostic factor for outcome among this patient population as more than half of patients with HH grade IV and V expired during their hospitalization despite aggressive treatment of their hematoma and aneurysm. Long-term functional outcome was poor in up to 85% of surviving patients with HH grade IV-V. It may be beneficial to discuss these prognostic factors with the family before implementing aggressive measures.

Abstract
BACKGROUND Of the MCA aneurysms, those located at the main bifurcation of the MCA (MbifA) are by far the most frequent. The purpose of this article is to review the practical anatomy, preoperative planning, and avoidance of complications in the microsurgical dissection and clipping of MbifAs. METHODS This review, and the whole series on intracranial aneurysms, is mainly based on the personal microneurosurgical experience of the senior author (JH) in 2 Finnish centers (Helsinki and Kuopio), which serve without patient selection the catchment area in southern and eastern Finland. RESULTS These 2 centers have treated more than 10,000 patients with intracranial aneurysm's since 1951. In the Kuopio Cerebral Aneurysm Data Base of 3005 patients with 4253 aneurysms, MbifAs formed 30% of all ruptured aneurysms, 36% of all unruptured aneurysms, 35% of all giant aneurysms, and 89% of all MCA aneurysms. Importantly, in 45%, rupture of MbifA caused an ICH. CONCLUSIONS Middle cerebral artery bifurcation aneurysms are often broad necked and may involve one or both branches of the bifurcation (M2s). The anatomical and hemodynamic features of MbifAs make them usually more favorable for microneurosurgical treatment. In population-based services, MbifAs are frequent targets of elective surgery (unruptured), acute surgery (ruptured), and emergency surgery (large ICH), even advanced approaches (giant). The challenge is to clip the neck adequately, without neck remnants, while preserving the bifurcational flow.

Abstract
BACKGROUND Distal middle cerebral artery aneurysms originate from branches of MCA distal to its main bifurcation or the peripheral branches. Distal middle cerebral artery aneurysms are the least frequently seen among the middle cerebral artery aneurysms. The purpose of this article is to review the practical anatomy, preoperative planning, and avoidance of complications in the microsurgical dissection and clipping of MdistAs. METHODS This review, and the whole series on intracranial aneurysms, are mainly based on the personal microneurosurgical experience of the senior author (JH) in 2 Finnish centers (Helsinki and Kuopio), which serve without patient selection the catchment area in Southern and Eastern Finland. RESULTS These 2 centers have treated more than 10000 aneurysm patients since 1951. In the Kuopio Cerebral Aneurysm Database of 3005 patients with 4253 aneurysms, 69 patients carrying altogether 78 MdistAs formed 5% of all MCA aneurysms. Among the 18 patients with ruptured MdistAs (23%), an ICH occurred in 9 (50%). CONCLUSIONS Distal middle cerebral artery aneurysms are rare. The microneurosurgical treatment of MdistAs is challenging. They are often difficult to localize during the operation, and lack of collateral circulation makes their occlusion more demanding. High rate of ICH and high tendency of rebleeding urge acute or emergency surgery in most of ruptured cases. Microneurosurgical clipping is the most effective treatment of MdistAs.

Abstract
BACKGROUND The M1As are located in the main trunk (M1) of the MCA, between the bifurcation of the ICA and the main bifurcation of M1. Proximal MCA aneurysms are often small and thin-walled, which makes their proper clipping tedious. There are few reports on their microsurgery. METHODS This review, and the whole series on intracranial aneurysms, is mainly based on the personal microneurosurgical experience of the senior author (JH) in 2 Finnish centers (Helsinki and Kuopio), which serve, without selection, the catchment area in the southern and eastern Finland. RESULTS These 2 centers have treated more than 10000 patients with aneurysm since 1953. We review the practical anatomy, preoperative planning, and avoidance of complications in the microsurgical dissection and clipping of M1As which form 7.4% of all intracranial and 14% of all MCA aneurysms in our patients. CONCLUSIONS Proximal MCA aneurysms are often wide-necked and intimately connected to an M1 branch at its origin on M1, features that favor exosurgery rather than endosurgery. The direction and course of the parent and branching arteries and the orientation of the fundus are the most important factors affecting the efficacy and safety of clipping.

Abstract
BACKGROUND Patients with a subarachnoid hemorrhage (SAH) accompanied by a massive intracerebral hemorrhage (ICH) or a full-packed intraventricular hemorrhage (IVH) have poor outcomes. We evaluated the clinical factors to predict the overall outcome in such patients. METHODS Data on nontraumatic SAH patients were collected and classified into 3 groups: the pure SAH group (SAH accompanied with neither ICH nor IVH), the ICH group (SAH accompanied with a massive ICH; hematoma 30 mL), and the IVH group (SAH and all ventricles were full-packed with hematoma). One hundred seventy-nine patients were in the ICH group and 109 in the IVH group. We evaluated clinical factors, such as the Hunt & Hess (H&H) score on admission, age, sex, history, rebleeding ratio, and the computerized tomography findings (SAH score). RESULTS The result of multivariate logistic regression analysis of clinical variables in the ICH group, good and intermediate H&H grades, younger age (<70), no rebleeding, and lower SAH score were associated with a favorable outcome. In the result of the multivariate logistic regression analysis of clinical variables in the IVH group, only a higher SAH score was associated with an unfavorable outcome. CONCLUSIONS In the ICH group, factors that could be used to predict a favorable outcome included good and intermediate H&H scores (1, 2, and 3) on admission, younger age (<70), and a lower SAH score. In the IVH group, the main factor that could be used to predict a favorable outcome was a lower SAH score.

Abstract
Object
Patients who present with an intraparenchymal hematoma associated with a ruptured aneurysm usually require urgent clot evacuation and aneurysm obliteration. The impact of the presence of hematoma on outcome has been poorly characterized. The authors report on 460 patients who had dense subarachnoid hemorrhage (SAH) (Fisher Grades 3 and 4) with and without associated hematoma.
Methods
Of the 959 consecutive patients who presented with SAH, 460 patients with Fisher Grade 3 and 4 SAH were analyzed and divided into two groups: those with (Group 1) and those without (Group 2) hematoma. The presenting Hunt and Hess grade and 6-month outcomes of the two groups were compared.
Of the 460 patients, 116 (25%) had intraparenchymal hematomas and admission Hunt and Hess grades were worse in Group 1 compared with Group 2. Outcome scores were worse for Group 1 compared with Group 2; however, when comparing Group 1 and Group 2 within the same initial Hunt and Hess score, there was no statistical difference in outcome.
Conclusions
Intraparenchymal hematoma in association with SAH does not differ significantly from those patients without associated hematomas. We therefore recommend aggressive clot evacuation and aneurysm obliteration.

Abstract
Between 20 and 30% of patients who suffer cerebral aneurysm rupture are in poor clinical grade when first evaluated. Management of these patients is controversial and challenging but can be successful with an aggressive proactive approach that begins with in the field resuscitation and continues through rehabilitation. In this article we review the epidemiology, pathology and pathophysiology, clinical features, evaluation, surgical and endovascular management, critical care, cost, and outcome prediction of patients in poor clinical grade after subarachnoid hemorrhage.

Abstract
During a six-year (1986-1992) 334 patients with subarachnoid hemorrhage (SAH) were admitted to the Department of Neurosurgery. Medical University of Lübeck, Germany. In 281 patients the SAH was caused by rupture of an intracranial arterial aneurysm, verified by angiography, postmortem examination, or at emergency operation without angiography. In 67 (23.8%) of the 281 aneurysmal SAH patients the initial computerized tomography (CT) demonstrated an intracerebral hematoma (ICH). An ICH localized in the temporal lobe due to the rupture of a middle cerebral artery (MCA) aneurysm was found in 47 patients (70.2%). Forty-three patients were considered for surgery with a surgical mortality of 8 (18.6%). In the group of 19 ICH patients not operated upon, 16 individuals died (84.2%). We therefore advocate active surgical management of ICH patients: hematoma evacuation and aneurysm clipping at the same operation. Emergency surgery in younger patients (grade V) with temporal ICH suggesting the rupture of a MCA or internal carotid artery (ICA) aneurysm can be done without angiography.

Abstract
In this retrospective study, the authors analyzed surgical outcomes in patients who suffered an intracerebral hemorrhage (ICH) as a result of a ruptured middle cerebral artery aneurysm. They studied 47 patients who underwent early aneurysm surgery and hematoma evacuation within 24 hours after onset of ICH. The types of ICH were classified into three groups according to their appearance on computerized tomography scanning: 1) temporal ICH; 2) intrasylvian hematoma; and 3) ICH with diffuse subarachnoid hemorrhage (SAH). Overall, 25 patients (53%) achieved a favorable outcome and 18 (38%) died. Factors that could be used to predict a favorable outcome included age less than 60 years, temporal ICH, World Federation of Neurological Surgeons Grade II or III, absence of a surgical complication, and a hematoma volume less than 25 ml. In the patients with temporal ICH, eight of nine patients achieved a good recovery and no patient developed a surgical complication or delayed ischemic deficit. The significant prognostic factor in patients with an intrasylvian hematoma was surgery within 6 hours after onset of symptoms. In patients with temporal ICH or intrasylvian hematoma, the results of the initial neurological examination did not accurately predict outcome. On the other hand, in patients with ICH and diffuse SAH, those patients who developed an ICH with a volume greater than 25 ml had a poor prognosis. These results indicate that aggressive surgical treatment should be performed in patients with a temporal ICH or an intrasylvian hematoma, regardless of the neurological findings on admission; in patients with ICH and diffuse SAH, a careful review of surgical indications is required.

Abstract
The authors retrospectively analyzed surgical outcomes in patients with an intracerebral hemorrhage (ICH) due to a ruptured middle cerebral artery aneurysm. A total of 47 patients with ICH who underwent early aneurysm surgery and hematoma evacuation within 24 hours following onset were studied. The types of ICH were classified into three groups by computerized tomography findings: 1) temporal ICH; 2) intrasylvian hematoma; and 3) ICH with diffuse subarachnoid hemorrhage (SAH). Overall, 25 patients (54%) had a favorable outcome and 18 (38%) died. Prognostic factors that predicted a favorable outcome included age less than 60 years, temporal ICH, World Federation of Neurological Surgeons Grade II or III, absence of a surgical complication, and a hematoma volume of less than 25 ml. In the patients with temporal ICH, eight of nine patients had a good recovery, and no patient developed a surgical complication or a delayed ischemic deficit. The most important predictive factor for a favorable outcome in patients with an intrasylvian hematoma was that they underwent early surgery (within 6 hours after symptom onset). In patients with a temporal ICH or intrasylvian hematoma, the initial neurological examination did not accurately predict outcome. By contrast, in the patients with ICH and diffuse SAH, those who developed an ICH with a volume of 25 ml or greater had a poor prognosis. These results suggest that aggressive surgical treatment should be initiated in patients with a temporal ICH or an intrasylvian hematoma, regardless of neurological findings on admission. In patients with an ICH and diffuse SAH, careful review of surgical indications is required.

Abstract
Conventional cerebral angiography has always been regarded as the gold standard for intracranial aneurysm detection. However, conventional angiography has the disadvantages of being invasive and time consuming. We present here 30 patients who underwent computed tomographic angiography (CTA) with three-dimensional reconstruction for the detection of intracranial aneurysms. All of these patients had subarachnoid hemorrhage or suspected intracranial aneurysms. CTA was performed in all patients with the use of a General Electric Hispeed Advantage helical scanner. Iohexol, 135 ml, was used as the contrast agent. Twenty-five patients also underwent conventional angiography for comparison. The five patients who underwent CTA only did not have conventional angiography because of poor clinical condition, and four of them subsequently died. Five patients had subarachnoid hemorrhage, but the results of both CTA and conventional angiography were negative for aneurysms. One patient had an incidental finding of a 3-mm left posterior communicating artery aneurysm on CTA, which was confirmed by conventional angiography. In the remaining 19 patients, 19 saccular aneurysms and 1 fusiform aneurysm were detected by CTA. Locations and sizes were confirmed by conventional angiography in all except two. The first exception was a patient who had a 2.5-mm anterior communicating artery aneurysm detected by CTA but not by conventional angiography. Surgical exploration confirmed the CTA diagnosis. The other exception was a patient in whom a 2-mm right posterior communicating artery aneurysm was detected by CTA but in whom conventional angiography showed a 2-mm left posterior communicating artery aneurysm. Unfortunately, there was no surgical confirmation in this case because the family of the patient refused surgery. Our results have demonstrated that CTA is a quick, reliable, and relatively simple diagnostic tool for intracranial aneurysms. In an emergent situation, such as a deteriorating patient with a hematoma, it is superior to either empiric exploration or infusion computed tomographic scans because it delineates the orientation and configuration of the aneurysm and its associated vascular anatomy.

Abstract
In a series of 1314 consecutive patients with cerebral aneurysms from a defined catchment area in eastern Finland (870,000 inhabitants), 561 patients (43%) had middle cerebral artery aneurysms (MCAAs). One or more associated aneurysms were common; 221 patients with MCAAs (39%) had multiple intracranial aneurysms (MIA). In other words, three-fourths (73%) of all patients with MIA had at least one MCAA. Multiple MCAAs, found in 111 patients (20%), were common in this Finnish population. One hundred of these patients had bilateral MCAAs, of whom 63 had mirror aneurysms, that is, aneurysms at the same site but on different sides. Thirty-five patients had "pure" mirror aneurysms, that is, they did not have any other aneurysms. Most MCAAs (81%) were located at the bifurcation. Three-fourths (72%) of the proximal MCAAs were associated with MIA. Giant aneurysms were significantly more common as single MCAAs than as any other single aneurysm. The frequency of intracerebral hematomas (42%) was by far higher in patients with MCAAs than in patients with ruptured aneurysms at other sites. Most of the intracerebral hematomas occurred in patients with bifurcation MCAAs that pointed laterally. Patients with MCAAs had surprisingly bad management outcomes despite good surgical results in patients with good Hunt and Hess grades. There were significantly more poor outcomes (Glasgow Outcome Scale score, 3-5) among patients with ruptured MCAAs than among those with any other anterior circulation aneurysms (32 and 25%, respectively). Also, the multiplicity of aneurysms increased the risk for poor outcome, which occurred in 39% of the patients who had MIA with one MCAA and 37% of those who had multiple MCAAs. Epilepsy, severe hemiparesis, and visual field deficits were the most common disabilities in long-term survivors, associated far more frequently with MCAAs than with aneurysm at other sites.

Abstract
BACKGROUND Intracerebral hematoma from ruptured aneurysms is one of the unfavorable factors for outcome in patients with subarachnoid hemorrhage. In this study, the clinical characteristics of intracerebral hematoma in patients with ruptured aneurysms were examined. METHODS The subjects were 512 patients who had been admitted by day 3 after aneurysmal rupture without episodes of rebleeding before the initial computed tomography (CT) scan. They were divided into two groups according to the findings of initial CT; groups 1 and 2 comprised patients with and without intracerebral hematoma, respectively. RESULTS Of the 512 patients, intracerebral hematoma was observed in 98 (19%). The incidence of intracerebral hematoma was higher in patients with distal anterior cerebral and middle cerebral artery aneurysms, compared with those at other sites (both, p < 0.01). Interhemispheric, callosal, and temporal lobe/sylvian hematomas were observed more frequently in patients with anterior communicating, distal anterior cerebral, and middle cerebral artery aneurysms, respectively, than in those with aneurysms at other sites. The incidence of rebleeding was 22% in group 1 and 14% in group 2 (p < 0.05). Clinical grades on admission were higher and outcome at 6 months after onset was less favorable in group 1 than in group 2 (both, p < 0.01). The larger the intracerebral hematoma, the higher was the clinical grade and the less favorable the outcome. However, when comparing management and surgical outcome under the same clinical grades, there was no significant difference between the two groups. CONCLUSIONS There was a close correlation between the site of hematoma and that of the ruptured aneurysm. Poor outcome in patients with intracerebral hematoma seems to be related to severity of clinical grade on admission.

Abstract
We report A series of 20 consecutive patients with 21 saccular aneurysms of the proximal (M1) segment of the middle cerebral artery. The incidence of M1 aneurysms was 3.0% among 660 patients with intracranial aneurysms and 12.9% among 155 patients with middle cerebral artery aneurysms in our center. Of the 20 patients, 2 were men and 18 were women. The aneurysms were classified into two types: the superior wall type (9 cases), arising at the origin of the lenticulostriate or fronto-orbital artery, and the inferior wall type (12 cases), arising at the origin of the early temporal branches. Twelve (60%) patients had ruptured M1 aneurysms. The incidence of multiple aneurysms was high (nine patients, 45%), and M1 aneurysms were responsible for subarachnoid hemorrhage in four patients. Of 14 M1 aneurysms greater than 5 mm in diameter, 11 (78.6%) ruptured. In contrast, only one (14.3%) of seven small (< or = 5 mm) aneurysms ruptured. In 12 patients with ruptured M1 aneurysms, intracerebral hematomas were recognized in 6 (50%). Intracerebral hematomas by the superior wall M1 aneurysms were located in the frontal lobe, and those by the inferior wall M1 aneurysms were in the temporal lobe. Fifteen patients (75%) made a useful recovery 6 months after surgery. Four patients (20%), who were in poor grade condition preoperatively, remained severely disabled. One patient died of sepsis 2 months after she recovered well from the operation. Special attention to the lenticulostriate arteries to avoid injury is critical for successful surgical treatment.

Abstract
The authors report their experience with 25 patients (mean age, 44.3 +/- 12.1 years) with an intracerebral hematoma (ICH) from a ruptured aneurysm who were emergently operated on without angiography. Instead, preoperative high-resolution infusion computed tomography (CT) scans were used to identify the aneurysm causing the hemorrhage. In all patients, the preoperative Glasgow Coma Scale score was < 5 and brain stem compression was evident. ICH was present in the frontal or temporal lobe and was often associated with intraventricular hemorrhage (n = 17) and significant (> 1 cm) midline shift (n = 18). Infusion CT scans correctly identified the aneurysm in all patients (middle cerebral artery, 18; posterior communicating artery, 2; carotid bifurcation, 3; anterior communicating artery, 2). Partial evacuation of the hematoma guided by infusion CT scan was usually required first to clip the aneurysm definitively using standard microvascular techniques. Intraoperative rupture occurred twice, and temporary clips were used on four occasions. Lobectomy (n = 8), decompressive craniotomy (n = 15), and ventriculostomy (n = 8) were required to control cerebral swelling. All patients underwent postoperative angiography to confirm aneurysm obliteration. Eleven unruptured aneurysms were subsequently identified. Nine had been predicted by infusion scan. Twelve patients survived, eight of whom were only moderately disabled and were independent at 6-months' follow-up. Of the 13 patients who died, all except one died within 4 days of admission. The authors conclude that although angiographic verification before aneurysm surgery is preferable, in the moribund patient with intracerebral hemorrhage, infusion CT scanning provides sufficient information concerning vascular anatomy to allow rational emergency craniotomy and aneurysm clipping.
