Abstract
BACKGROUND Decompressive craniectomies (DCs) are recommended for the treatment of raised intracranial pressure after acute ischaemic stroke. Some studies have demonstrated improved outcomes with early decompressive craniectomy (< 48 h from onset) in patients with malignant cerebral oedema following middle cerebral artery infarction. Limited data is available on suboccipital decompressive craniectomy after cerebellar infarction. AIMS Our primary objective was to determine whether the timing of DCs influenced functional outcomes at 6 months. Our secondary objectives were to analyse whether age, gender, the territory of stroke, or preceding thrombectomy impacts functional outcome post-DC. METHODS We conducted a retrospective study of patients admitted between January 2014 and December 2020 who had DCs post-acute ischaemic stroke. Data was collected from ICU electronic records, individual patient charts, and the stroke database. RESULTS Twenty-six patients had early DC (19 anterior/7 posterior) and 21 patients had late DC (17 anterior/4 posterior). There was no difference in the modified Rankin Scale (mRS) score of the two groups at 90 (p = 0.318) and 180 (p = 0.333) days post early vs late DC. Overall outcomes were poor, with 5 out of 46 patients (10.9%) having a mRS score ≤ 3 at 6 months. There was no difference in mRS scores between the patients who had hemicraniectomies for anterior circulation stroke (n = 35) and suboccipital DC for posterior circulation stroke (n = 11) (p = 0.594). CONCLUSION In this single-centre retrospective study, we found no significant difference in functional outcomes between patients who had early or late DC after ischaemic stroke.

Abstract
Suboccipital decompressive craniectomy with or without resection of necrosis is the preferred treatment for space-occupying cerebellar infarctions with neurological deterioration due to brainstem compression and obstructive hydrocephalus. We herein present our experience with treating space-occupying cerebellar infarctions successfully using endoscopic necrosectomy. A total of 27 patients were admitted to our hospital due to cerebellar infarctions between April 2021 and November 2023. Four patients required surgical interventions due to a drop in consciousness level or compression of the fourth ventricle and brainstem with acute hydrocephalus confirmed by a computed tomography (CT) scan. Three patients were performed endoscopic necrosectomy through a burr hole in a supine-lateral position. Removing most of the necrotic tissue was possible, resulting in early decompression of the fourth ventricle and brainstem. Endoscopic necrosectomy is less invasive than suboccipital decompressive craniectomy. An endoscopic necrosectomy can be performed for patients with unstable health conditions in a supine-lateral position. Therefore, endoscopic necrosectomy might be an effective method for treating patients with space-occupying cerebellar infarctions and poor general condition, although an objective evaluation of the extent and degree of removal is needed.

Abstract
BACKGROUND AND OBJECTIVES Space-occupying cerebellar stroke (SOCS) when coupled with neurological deterioration represents a neurosurgical emergency. Although current evidence supports surgical intervention in such patients with SOCS and rapid neurological deterioration, the optimal surgical methods/techniques to be applied remain a matter of debate. METHODS We conducted a retrospective, multicenter study of patients undergoing surgery for SOCS. Patients were stratified according to the type of surgery as (1) suboccipital decompressive craniectomy (SDC) or (2) suboccipital craniotomy with concurrent necrosectomy. The primary end point examined was functional outcome using the modified Rankin Scale (mRS) at discharge and at 3 months (mRS 0-3 defined as favorable and mRS 4-6 as unfavorable outcome). Secondary end points included the analysis of in-house postoperative complications, mortality, and length of hospitalization. RESULTS Ninety-two patients were included in the final analysis: 49 underwent necrosectomy and 43 underwent SDC. Those with necrosectomy displayed significantly higher rate of favorable outcome at discharge as compared with those who underwent SDC alone: 65.3% vs 27.9%, respectively ( P < .001, odds ratios 4.9, 95% CI 2.0-11.8). This difference was also observed at 3 months: 65.3% vs 41.7% ( P = .030, odds ratios 2.7, 95% CI 1.1-6.7). No significant differences were observed in mortality and/or postoperative complications, such as hemorrhagic transformation, infection, and/or the development of cerebrospinal fluid leaks/fistulas. CONCLUSION In the setting of SOCS, patients treated with necrosectomy displayed better functional outcomes than those patients who underwent SDC alone. Ultimately, prospective, randomized studies will be needed to confirm this finding.

Abstract
Importance According to the current American Heart Association/American Stroke Association guidelines, decompressive surgery is indicated in patients with cerebellar infarcts that demonstrate severe cerebellar swelling. However, there is no universal definition of swelling and/or infarct volume(s) available to support a decision for surgery. Objective To evaluate functional outcomes in surgically compared with conservatively managed patients with cerebellar infarcts. Design, Setting, and Participants In this retrospective multicenter cohort study, patients with cerebellar infarcts treated at 5 tertiary referral hospitals or stroke centers within Germany between 2008 and 2021 were included. Data were analyzed from November 2020 to November 2023. Exposures Surgical treatment (ie, posterior fossa decompression plus standard of care) vs conservative management (ie, medical standard of care). Main Outcomes and Measures The primary outcome examined was functional status evaluated by the modified Rankin Scale (mRS) at discharge and 1-year follow-up. Secondary outcomes included the predicted probabilities for favorable outcome (mRS score of 0 to 3) stratified by infarct volumes or Glasgow Coma Scale score at admission and treatment modality. Analyses included propensity score matching, with adjustments for age, sex, Glasgow Coma Scale score at admission, brainstem involvement, and infarct volume. Results Of 531 included patients with cerebellar infarcts, 301 (57%) were male, and the mean (SD) age was 68 (14.4) years. After propensity score matching, a total of 71 patients received surgical treatment and 71 patients conservative treatment. There was no significant difference in favorable outcomes (ie, mRS score of 0 to 3) at discharge for those treated surgically vs conservatively (47 [66%] vs 45 [65%]; odds ratio, 1.1; 95% CI, 0.5-2.2; P > .99) or at follow-up (35 [73%] vs 33 [61%]; odds ratio, 1.8; 95% CI, 0.7-4.2; P > .99). In patients with cerebellar infarct volumes of 35 mL or greater, surgical treatment was associated with a significant improvement in favorable outcomes at 1-year follow-up (38 [61%] vs 3 [25%]; odds ratio, 4.8; 95% CI, 1.2-19.3; P = .03), while conservative treatment was associated with favorable outcomes at 1-year follow-up in patients with infarct volumes of less than 25 mL (2 [34%] vs 218 [74%]; odds ratio, 0.2; 95% CI, 0-1.0; P = .047). Conclusions and Relevance Overall, surgery was not associated with improved outcomes compared with conservative management in patients with cerebellar infarcts. However, when stratifying based on infarct volume, surgical treatment appeared to be beneficial in patients with larger infarct volumes, while conservative management appeared favorable in patients with smaller infarct volumes.

Effect of massive cerebellar infarction on the outcomes of patients with acute basilar artery occlusion during hospitalization after endovascular treatment: A retrospective study. Medicine (Baltimore) 2023; 102:e34154. [PMID: 37478217 PMCID: PMC10662876 DOI: 10.1097/md.0000000000034154] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Accepted: 06/09/2023] [Indexed: 07/23/2023] Open
Abstract
Acute basilar artery occlusion (ABAO) after endovascular treatment (EVT) is often associated with a poor prognosis, particularly in patients with cerebellar infarction who may develop malignant cerebellar edema. The present study aimed to investigate how massive cerebellar infarction (MCI) affects hospitalization outcomes in ABVO patients who undergo EVT. We conducted a retrospective study of ABVO patients who underwent EVT at our hospital between September 2017 and September 2022. MCI was diagnosed using imaging techniques, and various prognostic scores were assessed during hospitalization to examine the relationship between MCI and these outcomes. We identified 42 ABAO patients, of whom 22 (52.4%) had MCI. Patients with MCI had a higher modified Rankin Scale (mRS) score at discharge compared to those without MCI (4.36 ± 1.14 vs 3.05 ± 1.85, P = .042, odds ratio [OR] (95% confidence interval [CI]) = 1.093 (0.083, 2.103)), and a lower Glasgow Coma Scale score (6.59 ± 4.0 vs 10.10 ± 5.07, P = .036, OR (95% CI) = -3.444 (-6.518, -0.369)). MCI was identified as an independent risk factor for an extremely poor prognosis (mRS ≥ 5) at discharge (P = .036, OR (95% CI) = 15.531 (1.603, 313.026)) and for no improvement in mRS score compared to onset (P = .013, OR (95% CI) = 0.025 (0.001, 0.274)). Additionally, an extremely poor prognosis was independently associated with stent implantation, EVT duration, and body mass index, while mRS score improvement was correlated with EVT duration and pulmonary infection. MCI in ABAO patients is a significant independent risk factor for a poor prognosis at discharge and no improvement in function score compared to onset. Early diagnosis and intervention are necessary to improve outcomes, particularly in high-risk populations.

Abstract
Malignant acute ischemic stroke (AIS) is characterized by acute neurological deterioration caused by progressive space-occupying brain edema, often occurring in the first hours to days after symptom onset. Without any treatment, the result is often fatal. Despite advances in treatment for AIS, up to 80% of patients with a large hemispheric stroke or cerebellar stroke are at risk of poor outcome. Decompressive surgery can be life-saving in a subgroup of patients with malignant AIS, but uncertainties exist on patient selection, predictors of malignant infarction, perioperative management, and timing of intervention. Although survivors are left disabled, most agree with the original decision to undergo surgery and would make the same decision again. In this narrative review, we focus on the clinical and radiological predictors of malignant infarction in AIS and outline the technical aspects of decompressive surgery as well as duraplasty and cranioplasty. We discuss the current evidence and recommendations for surgery in AIS, highlighting gaps in knowledge, and suggest directions for future studies. KEY POINTS: · Acute ischemic stroke from occlusion of a proximal intracranial artery can progress quickly to malignant edema, which can be fatal in 80% of patients despite medical management.. · Decompression surgery is life-saving within 48 hours of stroke onset, but the benefits beyond this time and in the elderly are unknown.. · Decompressive surgery is associated with high morbidity, particularly in the elderly. The decision to operate must be made after considering the individual's preference and expectations of quality of life in the context of the clinical condition.. · Further studies are needed to refine surgical technique including value of duraplasty and understand the role monitoring intracranial pressure during and after decompressive surgery.. · More studies are needed on the pathophysiology of malignant cerebral edema, prediction models including imaging and biomarkers to identify which subgroup of patients will benefit from decompressive surgery.. · More research is needed on factors associated with morbidity and mortality after cranioplasty, safety and efficacy of implants, and comparisons between them.. · Further studies are needed to assess the long-term effects of physical disability and quality of life of survivors after surgery, particularly those with severe neurological deficits..

Abstract
BACKGROUND There remains uncertainty regarding optimal definitive management for malignant posterior circulation infarcts (MPCI). While guidelines recommend neurosurgery for malignant cerebellar infarcts that are refractory to medical therapy, concerns exist about the functional outcome and quality of life after decompressive surgery. OBJECTIVE This study aims to evaluate the outcomes of surgical intervention compared to medical therapy in MPCI. METHODS In this systematic review, MEDLINE, Embase and Cochrane databases were searched from inception until 2 April 2021. Studies were included if they involved posterior circulation strokes treated with neurosurgical intervention and reported mortality and functional outcome data. Data were collected according to PRISMA guidelines. RESULTS The search yielded 6677 studies, of which 31 studies (comprising 723 patients) were included for analysis. From the included studies, we found that surgical therapy led to significant differences in mortality and functional outcomes in patients with severe disease. Neurological decline and radiological criteria were often used to decide the timing for surgical intervention, as there is currently limited evidence for preventative neurosurgery. There is also limited evidence for the superiority of one surgical modality over another. CONCLUSION For patients with MPCI who are clinically stable at the time of presentation, in terms of mortality and functional outcome, surgical therapy appears to be equivocal to medical therapy. Reliable evidence is lacking, and further prospective studies are rendered.

Abstract
Cerebellar ischemic stroke (CIS) is a morbid neurological event, with potentially fatal consequences. There is currently no objective standard of care regarding when surgical procedures are required for this entity. We retrospectively reviewed 763 patients with CIS, 247 patients of which had a stroke larger than 1 cm in greatest dimension on cranial imaging. In this subgroup, 11% of patients received ventriculostomy, 12% suboccipital craniectomy, and 9% mechanical endovascular thrombectomy. Various clinical and radiographic variables were examined for relationship to surgical procedures, 30-day mortality rate, and modified Rankin scores. The smallest volume of stroke requiring a surgical procedure was 15.5 mL3 (BrainLab Software). Patients receiving surgical procedures had a higher incidence of multi-territory infarctions, hydrocephalus, cistern compression, 4th ventricular compression, as well as younger age, lower admission GCS, higher admission NIHSS, and higher 30-day mortality/disability. Patients deemed to require surgical procedures for CIS have a higher expected morbidity and mortality than those not requiring surgery. Various clinical and radiographic variables, including stroke volume, can be used to guide selection of patients requiring surgery.

Abstract
Introduction Despite current clinical guidelines recommending suboccipital decompressive craniectomy (SDC) in cerebellar infarction when patients present with neurological deterioration, the precise definition of neurological deterioration remains unclear and accurate timing of SDC can be challenging. The current study aimed at characterizing whether clinical outcomes can be predicted by the GCS score immediately prior to SDC and whether higher GCS scores are associated with better clinical outcomes. Methods In a single-center, retrospective analysis of 51 patients treated with SDC for space-occupying cerebellar infarction, clinical and imaging data were evaluated at the time points of symptom onset, hospital admission, and preoperatively. Clinical outcomes were measured by the mRS. Preoperative GCS scores were stratified into three groups (GCS, 3-8, 9-11, and 12-15). Univariate and multivariate Cox regression analyses were performed using clinical and radiological parameters as predictors of clinical outcomes. Results In cox regression analysis GCS scores of 12-15 at surgery were significant predictors of positive clinical outcomes (mRS, 1-2). For GCS scores of 3-8 and 9-11, no significant increase in proportional hazard ratios was observed. Negative clinical outcomes (mRS, 3-6) were associated with infarct volume above 6.0 cm3, tonsillar herniation, brainstem compression, and a preoperative GCS score of 3-8 [HR, 2.386 (CI, 1.160-4.906); p = 0.018]. Conclusion Our preliminary findings suggest that SDC should be considered in patients with infarct volumes above 6.0 cm3 and with GCS between 12 and 15, as these patients may show better long-term outcomes than those in whom surgery is delayed until a GCS score below 11.

Abstract
Objective The purpose of this study was to analyze and discuss the clinical characteristics, long-term outcome, and prognostic factors of cerebellar strokes treated in a single health care facility in Mexico. Methods We retrospectively reviewed the medical records of adult patients admitted to our hospital with diagnosis of cerebellar ischemic and hemorrhagic stroke between 2018 and 2020. Baseline data included sociodemographic and radiological variables, treatment (surgical versus conservative), and Glasgow Coma Scale on arrival (GCSOA). The final neurological outcome was evaluated with the Glasgow Outcome Scale (GOS) six months after hospital discharge. Results Ten patients (seven male and three female) with a mean age of 57.9 ± 9.3 years were included, six with cerebellar ischemic infarction and four with cerebellar hemorrhage. Out of the 10 patients, four underwent surgery (suboccipital decompressive craniectomy {SDC} ± ventriculostomy). The outcome was favorable in four cases (40%) and unfavorable in six (60%). Patients who underwent surgical treatment fared worse with all four cases associating poor outcome. The comparison between good and poor outcome groups showed significant differences in the presence of obstructive hydrocephalus (one versus six, p = 0.05) and poorer GCSOA (6.16 ± 1.72 versus 12.5 ± 3.6, p = 0.05), associating poorer outcome. Conclusion There is still controversy regarding the appropriate management of cerebellar strokes. The presence of obstructive hydrocephalus and poorer GCSOA are associated to worse outcomes.

Abstract
Background and PurposeSurgical decompression of the posterior fossa is often performed in cases with a space-occupying cerebellar infarction to prevent coma and death. In this study, we analyzed our institutional experience with this condition. We specifically attempted to address timing issues and investigated the role of cerebellar necrosectomy using imaging data and conducting volumetric analyses.MethodsWe retrospectively studied pertinent clinical and imaging data, including computerized volumetric analyses (preoperative/postoperative infarction volume, necrosectomy volume, and posterior fossa volume), from all 49 patients who underwent posterior fossa decompression surgery for cerebellar infarction in our department from January 2012 to January 2021.ResultsThirty-five (71%) patients had a Glasgow Coma Scale (GCS) of 14–15 at admission vs. only 14 (29%) before vs. 41 (84%) following surgery. Seven (14%) patients had preventive surgery (initial GCS 14–15, preoperative GCS change ≤ 1). Only 18 (37%) patients had an mRS score of 0–3 at discharge. Estimated overall survival was 70.5% at 1 year. Interestingly, 18/20 (90%) surviving cases had a modified Rankin Scale (mRS) outcome of 0–3 (mRS 0–2: 12/20 [60%]) 1 year after surgery. Surgical timing, including preventive surgery and mass effect of the infarct, in the posterior fossa assessed semi-quantitatively (Kirollos grade) and with volumetric parameters that were not predictive of the patients' (functional) outcomes.ConclusionPosterior fossa decompression for cerebellar infarction is a life-saving procedure, but rapid recovery of the GCS after surgery does not necessarily translate into good functional outcome. Many patients died during follow-up, but long-term mRS outcomes of 4–5 are rare. Surgery should probably aim primarily at pressure relief, and our clinical as well as volumetric data suggest that the impact of removing an infarcted tissue may be limited. It is presumably relatively safe to initially withhold surgery in cases with a GCS of 14–15.

Abstract
Cerebral edema is a common complication of acute ischemic stroke that leads to poorer functional outcomes and substantially increases the mortality rate. Given that its negative effects can be reduced by more intensive monitoring and evidence-based interventions, the early identification of patients with a high risk of severe edema is crucial. Neuroimaging is essential for the assessment and prediction of edema. Simple markers, such as midline shift and hypodensity volume on computed tomography, have been used to evaluate edema in clinical trials; however, advanced techniques can be applied to examine the underlying mechanisms. In this study, we aimed to review current imaging tools in the assessment and prediction of cerebral edema to provide guidance for using these methods in clinical practice.

Abstract
Objective Suboccipital decompression has been established as standard therapeutic procedure for raised intracranial pressure caused by mass-effect associated pathologies in posterior fossa. Several different surgical techniques of dural closure have been postulated to achieve safe decompression. The aim of this study was to examine the differences between fibrin sealant patch (FSP) and dural reconstruction (DR) in suboccipital decompression for acute mass-effect lesions. Methods We retrospectively analyzed our institutional data of patients who underwent suboccipital decompression due to spontaneous intracerebellar hemorrhage, cerebellar infarction and acute traumatic subdural hematoma between 2010 and 2019. Two different dural reconstruction techniques were performed according to the attending neurosurgeon: (1) fibrin sealant patch (FSP), and (2) dural reconstruction (DR) including the use of dural patch. Complications, operative time, functional outcome and the necessity of a ventriculoperitoneal shunt (VP Shunt) were assessed and further analyzed. Results Overall, 87 patients were treated at the authors’ institution (44 in FSP group, 43 in DR group). Glasgow coma scale on admission and preoperative coagulation state did not differ between the groups. Postoperatively, we found no difference in cerebrospinal fluid leakage or chronic hydrocephalus between the groups (p = 0.47). Revision rates were 2.27% (1/44 patients) in the FSP group, compared to 16.27% (7/43) in the DR group (p < 0.023). Operative time was significantly shorter in the FSP group (90.3 ± 31.0 min vs. 199.0 ± 48.8 min, p < 0.0001). Conclusion Rapid closure technique in suboccipital decompression is feasible and safe. Operative time is hereby reduced, without increasing complication rates.

Abstract
We describe a patient presented with clinically a small cerebellar ischaemic stroke but required emergency decompression within 24 hours of symptoms onset after incidental finding of severe mass effect on imaging without any change in her mild clinical symptoms. Her initial multimodal acute stroke imaging, non-contrast CT of the brain and CT angiography from aortic arch to vertex were normal. CT perfusion showed a very small deficit only. The malignant mass effect was picked on an MRI scan performed routinely as part of a clinical trial, 32 hours after stroke. Our case highlights stroke evolution, and mass effect may be insidious and faster than anticipated in the posterior fossa. Cerebellar stroke of any severity diagnosed clinically and radiologically may benefit from routine follow-up imaging at 24 hours from onset.

Abstract
BACKGROUND Decompressive craniectomy (DC) has been shown to be an effective treatment for malignant cerebral infarction (MCI). There are limited nationwide studies evaluating outcome after craniectomy for MCI. OBJECTIVE To describe the evolution in DC practices for MCI, long-term survival, and associated prognostic factors. METHODS We searched the French medico-administrative national database to retrieve patients who underwent DC between 2008 and 2017. RESULTS A total of 1841 cases of DC were performed over 10 years in 51 centers. Mean age at procedure was 50.9 years, 18% were above 60 years, and 64.4% were male. There was a significant increase in DC for MCI over the 10 years (p < 0.001), and the annual volume of procedures more than doubled (95/year vs. 243/year). Early survival at one week and one month was 86%, 95%CI (84.5, 87.6) and 79.7%, 95%CI (77.8, 81.5), respectively. Long-term survival at 1 and 5 years were 73.6%, 95%CI (71.6, 75.7) and 68.9%, 95%CI (66.5, 71.4), respectively. Patients below 60 years at the time of DC (HR = 0.5; 95%CI [0.4, 0.7], p < 0.001), DC being performed in a center with a high surgical activity (HR = 0.8; 95%CI [0.6, 0.9], p = 0.002), and the patients having unimpaired consciousness (HR = 0.6; 95%CI [0.5, 0.8], p < 0.001) were associated with increased survival in both univariate and adjusted Cox regressions. 18.7% of the survivors had a cranioplasty inserted within 3 months and 57.8% within 6 months. The probability of having a cranioplasty at one year was 75.6%, 95%CI (77.9, 73.1). CONCLUSION Over the past 10 years in France, DC has been increasingly performed for MCI regardless of age. However, in-hospital mortality remains considerable, as about one quarter of patients died within the first weeks. For those who survive beyond 6 months, the risk of death significantly decreases. Early mortality is especially high for comatose patients above 60 years operated in inexperienced centers. Most of those who remain in good functional status tend to undergo a cranioplasty within the year following DC.

Abstract
BACKGROUND Preprocedural predictors of outcome in patients with acute basilar artery occlusion (ABAO) who have undergone endovascular treatment (EVT) remain controversial. Our aim was to determine if pre-EVT diffusion-weighted imaging cerebellar infarct volume (CIV) is a predictor of 90-day outcomes. METHODS We analyzed consecutive MRI-selected endovascularly treated patients with ABAO within the first 24 hours after symptom onset. Successful reperfusion was defined as a modified Thrombolysis in Cerebral Infarction score of 2b-3. Using the initial MRI, baseline CIV was calculated in mL on an apparent diffusion coefficient map reconstruction (Olea Sphere software). CIV was analyzed in univariate and multivariable models as a predictor of 90-day functional independence (modified Rankin Scale (mRS) 0-2) and mortality. According to receiver operating characteristic (ROC) analysis, the optimal cut-off was determined by maximizing the Youden index to evaluate the prognostic value of CIV. RESULTS Of the 110 MRI-selected patients with ABAO, 64 (58.18%) had a cerebellar infarct. The median CIV was 9.6 mL (IQR 2.7-31.4). Successful reperfusion was achieved in 81.8% of the cases. At 90 days the proportion of patients with mRS ≤2 was 31.8% and the overall mortality rate was 40.9%. Baseline CIV was significantly associated with 90-day mRS 0-2 (p=0.008) in the univariate analysis and was an independent predictor of 90-day mortality (adjusted OR 1.79, 95% CI 1.25 to 2.54, p=0.001). The ROC analysis showed that a CIV ≥4.7 mL at the initial MRI was the optimal cut-off to discriminate patients with a higher risk of death at 90 days (area under the ROC curve (AUC)=0.74, 95% CI 0.61 to 0.87, sensitivity and specificity of 87.9% and 58.1%, respectively). CONCLUSIONS In our series of MRI-selected patients with ABAO, pre-EVT CIV was an independent predictor of 90-day mortality. The risk of death was increased for baseline CIV ≥4.7 mL.

Cerebellar Necrosectomy Instead of Suboccipital Decompression: A Suitable Alternative for Patients with Space-Occupying Cerebellar Infarction. World Neurosurg 2020; 144:e723-e733.

Abstract
OBJECTIVE Space-occupying cerebellar ischemic strokes (SOCSs) often lead to neurological deterioration and require surgical intervention to release pressure from the posterior fossa. Current guidelines recommend suboccipital decompressive craniectomy (SDC) with dural expansion when medical therapy is not sufficient. However, no good-quality evidence is available to support this surgical practice, and the surgical timing and technique both remain controversial. We have described an alternative to SDC, surgical evacuation of infarcted tissue (necrosectomy) and its clinical outcomes. METHODS In the present retrospective, single-center study, 34 consecutive patients with SOCS undergoing necrosectomy via osteoplastic craniotomy were included. The patient characteristics and radiological findings were evaluated. To differentiate the effects of age on the functional outcomes, the patients were divided into 2 groups (group I, age ≤60 years; and group II, age >60 years). Functional outcomes were assessed using the Glasgow outcome scale, modified Rankin scale, and Barthel index at discharge and 30 days postoperatively. RESULTS In our cohort, we observed overall mortality of 21%, with good functional outcomes (Glasgow outcome scale score ≥4) for 76% of the patients. No statistically significant differences in mortality or functional outcomes were observed between the 2 patient groups. Comparing our data with a recent meta-analysis of SDC, the number of adverse events and unfavorable outcome showed equipoise between the 2 treatment modalities. CONCLUSIONS Necrosectomy appears to be a suitable alternative to SDC for SOCS, achieving comparable mortality and functional outcomes. Further trials are necessary to evaluate which surgical technique is more beneficial in the setting of SOCSs.

Abstract
The coronavirus disease 2019 (COVID-19) has amazed by its distinct forms of presentation and severity. COVID-19 patients can develop large-scale ischemic strokes in previously healthy patients without risk factors, especially in patients who develop an acute respiratory distress syndrome (SARS-CoV-2). We hypothesize that ischemic events are usually the result of the combined process of a pro-inflammatory and pro-coagulant state plus vascular endothelial dysfunction probably potentiated by hypoxia, hemodynamic instability, and immobilization, as reported in other cases. To the best of our knowledge, we report the first case of partial obstruction of a vertebral artery in a patient with COVID-19. Decompressive surgery remains a life-saving maneuver in these patients (as in other non-COVID-19 strokes) and requires further investigation.

Predicting Surgical Intervention in Cerebellar Stroke: A Quantitative Retrospective Analysis. World Neurosurg 2020; 142:e160-e172.

Abstract
BACKGROUND Debate still exists regarding whether preventive surgical decompression should be offered to high-risk patients experiencing cerebellar stroke. This study aimed to predict neurologic decline based on risk factors, volumetric analysis, and imaging characteristics. METHODS This retrospective cohort study comprised patients ≥18 years who presented with acute cerebellar ischemic stroke (CIS) between January 2011 and December 2016. Diagnostic imaging was used to calculate metrics based on individual stroke, cerebellar, and posterior fossa volumes. Head computed tomography scans on presentation and day of peak swelling were used to tabulate a CIS score. RESULTS The study included 86 patients; most were male and African American. Posterior inferior communicating artery stroke was most common (50%). On initial presentation imaging, 18.6% had documented hydrocephalus, 20.9% had brainstem compression, 22.1% had brainstem stroke, and 39.5% had stroke in another vascular territory. Cardioembolic stroke was the most common etiology, followed by cryptogenic stroke. Overall, patients who underwent surgical intervention had larger stroke volumes on presentation. Patients undergoing surgical intervention also experienced faster cerebellar swelling compared with patients without intervention. Total CIS scores were statistically significant and remained significant on the peak day of swelling. CIS score was independently associated with neurosurgical intervention; patients in this group with delayed interventions (median CIS score, 6; range, 4-8) later deteriorated and required emergent surgical decompression. Eleven patients without intervention had CIS score >6; 4 patients died of stroke complications. CONCLUSIONS Volumetric studies and CIS score are objective measures that may help predict decline on imaging before clinical deterioration.

Abstract
In patients over 80 years old, 4 of the 5 evidence-based acute treatments of ischemic stroke, i.e. stroke unit treatment, antiplatelet therapy, intravenous thrombolysis (IVT) and mechanical thrombectomy (MT) are effective but with a higher morbidity than in younger patients. The indications for the more invasive forms of treatment, such as IVT and MT are given in principle but have to be oriented to the individual patient comorbidities. In the case of failure of these procedures a consistent therapeutic target change to palliative measures is appropriate. Decompressive craniotomy in space-occupying media infarction can be indicated up to the relative age limit of 60 years and absolute age limit of 70 years. Patients over 80 years often do not undergo IVT or MT. Although the German approval for alteplase within the framework of IVT over the age of 80 years suggests a careful and critical review of the indications, its use is generally recommended.

Abstract
BACKGROUND Posterior fossa surgery is the established treatment for large cerebellar strokes with brainstem compression. Despite this, there is a paucity of data for long-term outcomes. METHODS A retrospective analysis of patients who underwent posterior fossa surgery for cerebellar hemorrhages and infarcts was performed to compare their difference in 6-month outcomes and to identify factors that affect outcomes. Patients were dichotomized into groups with good outcomes (modified Rankin scale [mRS] score 0-3) or poor outcomes (mRS score 4-6). Sex, age, preoperative Glasgow Coma Scale score, Charleston comorbidity index, time to surgery, intraventricular hemorrhage, surgical complications, length of intensive care unit and hospital stay, shunt dependence, and tracheostomy rates were analyzed. RESULTS In total, 126 patients were recruited: 76 in hemorrhage group and 50 in infarct group. There was a greater mortality in the hemorrhage group (P = 0.0730). At 6 months, more patients in the hemorrhage group had poor outcomes (P = 0.0074, odds ratio 3.04) and greater mortality (P = 0.0730, odds ratio 2.20). More patients in the hemorrhage group required a tracheostomy (P = 0.0245). Factors predictive of poor outcome include older age (P = 0.0108), Glasgow Coma Scale score ≤8 (P = 0.0011), and tracheostomy (P = 0.0269). A total of 69.2% of patients had improvements in mRS scores at 6 months. Shorter length of stay (P = 0.0003) and discharge to a rehabilitation hospital (P = 0.0001) were predictive of functional improvement. CONCLUSIONS Patients who underwent posterior fossa surgery for cerebellar hemorrhage had worse outcomes compared with patients with cerebellar infarcts and were more likely to require a tracheostomy. Rehabilitation helped to improved outcomes.

Abstract
Malignant stroke occurs in a subgroup of patients suffering from ischemic cerebral infarction and is characterized by neurological deterioration due to progressive edema, raised intracranial pressure, and cerebral herniation. Decompressive craniectomy (DC) is a surgical technique aiming to open the “closed box” represented by the non-expandable skull in cases of refractory intracranial hypertension. It is a valuable modality in the armamentarium to treat patients with malignant stroke: the life-saving effect has been proven for both supratentorial and infratentorial DC in virtually all age groups. This leaves physicians with the difficult task to decide who will require early or preemptive surgery and who might benefit from postponing surgery until clear evidence of deterioration evolves. Together with the patient’s relatives, physicians also have to ascertain whether the patient will have acceptable disability and quality of life in his or her presumed perception, based on preoperative predictions. This complex decision-making process can only be managed with interdisciplinary efforts and should be supported by continued research in the age of personalized medicine.

Abstract
Ischemic stroke is one of the leading causes for death and disability worldwide. In patients with large space-occupying infarction, the subsequent edema complicated by transtentorial herniation poses a lethal threat. Especially in patients with malignant middle cerebral artery infarction, brain swelling secondary to the vessel occlusion is associated with high mortality. By decompressive craniectomy, a significant proportion of the skull is surgically removed, allowing the ischemic tissue to shift through the surgical defect rather than to the unaffected regions of the brain, thus avoiding secondary damage due to increased intracranial pressure. Several studies have shown that decompressive craniectomy reduces the mortality rate in patients with malignant cerebral artery infarction. However, this is done for the cost of a higher proportion of patients who survive with severe disability. In this review, we will describe the clinical and radiological features of malignant middle cerebral artery infarction and the role of decompressive craniectomy and additional therapies in this condition. We will also discuss large cerebellar stroke and the possibilities of suboccipital craniectomy.

Abstract
OBJECTIVES Suboccipital decompressive craniectomy (SDC) is considered the best treatment option in patients with space-occupying cerebellar infarction and clinical signs of deterioration. The primary purpose of this study was to evaluate long-term functional outcome in patients one year after SDC for space-occupying cerebellar infarction, and secondly, to determine factors associated with outcome. PATIENTS AND METHODS All patients treated with SDC due to space-occupying cerebellar infarction between January 2009 and October 2015 were included in the study. Data was retrospectively collected from patient records, CT/MRI scans and surgical protocols. Long-term functional outcome was determined by the modified Rankin Scale (mRS) and mRS ≥ 4 was defined as unfavorable outcome. RESULTS Twenty-two patients (16 male, 6 female) were included in the study. Median age was 53 years. Nine patients were treated with external ventricular drainage as an initial treatment attempt prior to SDC. Median time from symptom onset (stroke ictus) to initiation of the SDC surgery was 48 h (IQR 28-99 hours) and median GCS before SDC was 8 (IQR 5-10). At follow up, median mRS was 3 (IQR 2-6). Outcome was favorable (mRS 0-3) in 12 patients and unfavorable in 10 (3 with major disability, 7 dead). Brainstem infarction and bilateral cerebellar infarction were associated with unfavorable outcome. CONCLUSIONS In this small study, functional long-term outcome in patients with space-occupying cerebellar infarction treated by SDC was acceptable and comparable to previously published results (favorable outcome in 54% of patients). Brainstem infarction and bilateral cerebellar infarction were associated with unfavorable outcome.
