[PMID: 38561586 DOI: 10.1007/s12028-024-01958-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Accepted: 02/06/2024] [Indexed: 04/04/2024]
Abstract
BACKGROUND We aimed to investigate the associations of macrophage migration inhibitory factor (MIF), toll-like receptors 2 and 4 (TLR2/4), and matrix metalloproteinase 9 (MMP9) with 3-month poor outcome, death, and malignant cerebral edema (MCE) in patients with large hemispheric infarction (LHI). METHODS Patients with LHI within 24 h of onset were enrolled consecutively. Serum MIF, TLR2/4, and MMP9 concentrations on admission were measured. Poor outcome was defined as a modified Rankin Scale score of ≥ 3 at 3 months. MCE was defined as a decreased level of consciousness, anisocoria and midline shift > 5 mm or basal cistern effacement, or indications for decompressive craniectomy during hospitalization. The cutoff values for MIF/MMP9 were obtained from the receiver operating characteristic curve. RESULTS Of the 130 patients with LHI enrolled, 90 patients (69.2%) had 3-month poor outcome, and MCE occurred in 55 patients (42.3%). Patients with serum MIF concentrations ≤ 7.82 ng/mL for predicting 3-month poor outcome [adjusted odds ratio (OR) 2.827, 95% confidence interval (CI) 1.144-6.990, p = 0.024] also distinguished death (adjusted OR 4.329, 95% CI 1.841-10.178, p = 0.001). Similarly, MMP9 concentrations ≤ 46.56 ng/mL for predicting 3-month poor outcome (adjusted OR 2.814, 95% CI 1.236-6.406, p = 0.014) also distinguished 3-month death (adjusted OR 3.845, 95% CI 1.534-9.637, p = 0.004). CONCLUSIONS Lower serum MIF and MMP9 concentrations at an early stage were independently associated with 3-month poor outcomes and death in patients with LHI. These findings need further confirmation in larger sample studies.

Comer AR, Jawed A, Roeder H, Kramer N. The impact of sex and gender on advanced stroke interventions and end-of-life outcomes after stroke. J Stroke Cerebrovasc Dis 2024; 33:107820. [PMID: 38876458 DOI: 10.1016/j.jstrokecerebrovasdis.2024.107820] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 06/07/2024] [Accepted: 06/11/2024] [Indexed: 06/16/2024] Open
Abstract
OBJECTIVES In this review, we examine the impact of sex and gender on advanced stroke interventions and end-of-life outcomes after stroke and discuss the current theories, available evidence, and gaps in the literature. METHODS A scoping review of the literature was conducted to determine gender differences on advanced stroke interventions and end-of-life outcomes after stroke. The study team utilized PubMed to conduct a review of the literature and included research studies related to sex, gender, advanced stroke interventions, and end-of-life outcomes after stroke. The PRISMA process for conducting a scoping review was followed. RESULTS This review found that although evidence regarding gender differences in advanced stroke interventions and end-of-life care after stroke is disparate, some gender differences do indeed exist. Women are less likely to receive thrombectomy or alteplase, women are more likely to receive palliative care intervention, hospice, and women experience stroke mortality at higher rates. CONCLUSIONS Gender differences in end-of-life care after stroke are apparent with women experiencing lower rates of life sustaining interventions, and higher rates of mortality, palliative and hospice care. More research is needed to identify variables associated with or responsible for gender differences during advance interventions and end-of-life care after stroke.

Abstract
OBJECTIVES Decompressive hemicraniectomy can be life-saving for malignant middle cerebral artery acute ischemic stroke (AIS). However, utilization and outcomes for hemicraniectomy in the US are not known. We sought to analyze baseline characteristics and outcomes of patients receiving hemicraniectomy for AIS in the US. MATERIALS AND METHODS We identified adults who received hemicraniectomy for AIS, identified with validated International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9) code in the Nationwide Readmissions Database 2014. We calculated 30-day readmission rates, reasons for readmission, and procedures performed. RESULTS 2850 of 531,896 AIS patients (0.54%) received hemicraniectomy. Although patients receiving hemicraniectomy were more likely to be younger (57.0, 95% CI 56.0-58.0; vs 70.9, 95% CI 70.6-71.2; p < 0.0001) and male (40% vs 51.2% female; p<0.0001), 46.3% of patients who received hemicraniectomy were age 60 years and older. Patients 60 years or older receiving hemicraniectomy were more likely to die (29.9% vs 21.9%, p = 0.0081). Hemicraniectomy was more frequently performed at large hospitals (75.3% vs 57.7%; p < 0.0001) in urban areas (99.1% vs 90.3%; p < 0.0001) designated as metropolitan teaching hospitals (88.3% vs 63.4%; p < 0.0001). 30-day readmissions were most commonly due to infection (31.5%), non-infectious medical complications (17.7%), and surgical complications (13.8%). These readmissions were critical. CONCLUSIONS Although hemicraniectomy is used more frequently in the treatment of younger, male, ischemic stroke patients, only half of the patients receiving hemicraniectomy in 2014 were <60 years old. Regardless of age, hemicraniectomy is a geographically segregated procedure, only being performed in large metropolitan teaching hospitals.

Acta Neurochir (Wien) 2019; 161:473-481. [PMID: 30644012 PMCID: PMC6407745 DOI: 10.1007/s00701-018-03791-3] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2018] [Accepted: 12/24/2018] [Indexed: 11/25/2022]
Abstract
Background Bone flap resorption (BFR) is the most prevalent complication resulting in autologous cranioplasty failure, but no consensus on the definition of BFR or between the radiological signs and relevance of BFR has been established. We set out to develop an easy-to-use scoring system intended to standardize the interpretation of radiological BFR findings. Methods All 45 autologous cranioplasty patients operated on at Oulu University Hospital from 2004 to 2014 were identified, and the bone flap status of all the available patients was evaluated using the new scoring system. Derived from previous literature, a three-variable score for the detection of BFR changes is proposed. The variables “Extent” (estimated remaining bone volume), “Severity” (possible perforations and their measured diameter), and “Focus” (the number of BFR foci within the flap) are scored from 0 to 3 individually. Using the sum of these scores, a score of 0–9 is assigned to describe the degree of BFR. Additionally, independent neurosurgeons assessed the presence and relevance of BFR from the same data set. These assessments were compared to the BFR scores in order to find a score limit for relevant BFR. Results BFR was considered relevant by the neurosurgeons in 11 (26.8%) cases. The agreement on the relevance of BFR demonstrated substantial strength (κ 0.64, 95%CI 0.36 to 0.91). The minimum resorption score in cases of relevant BFR was 5. Thus, BFR with a resorption score ≥ 5 was defined relevant (grades II and III). With this definition, grade II or III BFR was found in 15 (36.6%) of our patients. No risk factors were found to predict relevant BFR. Conclusions The score was proven to be easy to use and we recommend that only cases with grades II and III BFR undergo neurosurgical consultation. However, general applicability can only be claimed after validation in independent cohorts.

[DOI: 10.1161/strokeaha.116.014727] [Citation(s) in RCA: 66] [Impact Index Per Article: 9.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2016] [Revised: 12/01/2016] [Accepted: 12/07/2016] [Indexed: 11/16/2022]
Abstract
Background and Purpose—
Previous clinical trials were not designed to discern the optimal timing of decompressive craniectomy for stroke, and the ideal surgical timing in patients with space-occupying infarction who do not exhibit deterioration within 48 hours is debated.
Methods—
Patients undergoing decompressive craniectomy for stroke were extracted from the Nationwide Inpatient Sample (2002–2011). Multivariable logistic regression evaluated the association of surgical timing with mortality, discharge to institutional care, and poor outcome (a composite end point including death, tracheostomy and gastrostomy, or discharge to institutional care). Covariates included patient demographics, comorbidities, year of admission, and hospital characteristics. However, standard stroke severity scales and infarct volume were not available.
Results—
Among 1301 admissions, 55.8% (n=726) underwent surgery within 48 hours. Teaching hospital admission was associated with earlier surgery (
P
=0.02). The timing of intervention was not associated with in-hospital mortality. However, when evaluated continuously, later surgery was associated with increased odds of discharge to institutional care (odds ratio, 1.17; 95% confidence interval, 1.05–1.31,
P
=0.005) and of a poor outcome (odds ratio, 1.12; 95% confidence interval, 1.02–1.23;
P
=0.02). When evaluated dichotomously, the odds of discharge to institutional care and of a poor outcome did not differ at 48 hours after hospital admission, but increased when surgery was pursued after 72 hours. Subgroup analyses found no association of surgical timing with outcomes among patients who had not sustained herniation.
Conclusion
s—In this nationwide analysis, early decompressive craniectomy was associated with superior outcomes. However, performing decompression before herniation may be the most important temporal consideration.

Abstract
Malignant cerebral edema is a potential consequence of large territory cerebral infarction, as the resultant elevation in intracranial pressure may progress to transtentorial herniation, brainstem compression, and death. In appropriate patients, decompressive hemicraniectomy (DHC) reduces mortality without increasing the risk of severe disability. However, as the foundational DHC randomized, controlled trials excluded patients greater than 60 years of age, the appropriateness of DHC in older adults remains controversial. Recent clinical trials among elderly participants, including DESTINY II, reported that DHC reduces mortality, but may leave patients with substantial morbidity. Nationwide analyses have demonstrated generalizability of such data. However, what constitutes an acceptable outcome - the perspective on quality of life after survival with substantial disability - varies between clinicians, patients, and caregivers. Consequently, quality of life measures are being increasingly incorporated into stroke research. This review summarizes the impact of DHC in space-occupying cerebral infarction, and the influence of patient age on postoperative survival, functional capacity, and quality of life-all key factors in the clinical decision process. Ultimately, these data underscore the inherent complexity in balancing scientific evidence, clinical expertise, and patient and family preference when pursuing hemicraniectomy among the elderly.

Abstract
BACKGROUND The increasing use of endovascular treatments has led to higher recanalization rates and better clinical outcomes compared with intravenous thrombolysis alone. Stent retrievers represent the latest development for recanalization of large vessel occlusions. Decompressive hemicraniectomy has proved beneficial in patients suffering from rising intracranial pressure after malignant stroke. AIMS AND/OR HYPOTHESIS We investigated the effect of the implementation of stent retriever treatment on the frequency of hemicraniectomy as a surrogate marker for infarct size and thus for poor neurological outcome. METHODS Patients with acute ischemic stroke were retrospectively studied. We compared the frequency of hemicraniectomy following proximal artery occlusion of the internal carotid artery and middle cerebral artery main stem in the years before (2009 and 2010) and after (2012 and 2013) introducing stent retrievers. RESULTS Overall, 497 patients with proximal arterial occlusion were included in the study. Of 253 patients admitted in the years 2009 and 2010 44 (17.4 %) and of 244 patients admitted in 2012 and 2013, 20 (8.2 %) received a hemicraniectomy. This decrease in the proportion of hemicraniectomies was statistically significant (p < 0.01). CONCLUSIONS The findings in this study illustrate a significantly reduced rate of hemicraniectomies in patients with proximal artery occlusions after implementation of thrombectomy with stent retriever. Hereby, we could show a significant reduction of malignant infarctions after thrombectomy with stent retriever.

Abstract
OBJECTIVE Decompressive hemicraniectomy (DHC) for malignant middle cerebral artery (MCA) infarction has been shown to reduce mortality and improve functional outcomes in young adults; however, there is currently debate regarding how routinely such surgery should be performed in the clinical setting, considering the very high rate of disability and functional dependence among survivors. We herein report the current status of the frequency of and indications for DHC for malignant MCA infarction in Japan. METHODS We retrospectively studied of cohort cases of DHC for malignant MCA infarction treated at pivotal teaching neurosurgical departments in Japan between January 2011 and December 2011. Information was obtained regarding patient characteristics, radiologic features, and outcomes during follow-up. The end points included 30-day mortality rate and functional outcomes, as measured according to the modified Rankin scale (mRS) score at 3 months. RESULTS Three hundred fifty-five patients underwent DHC at 259 neurosurgical departments who replied to the survey, corresponding to a rate of 8.7% of the 4092 candidates with malignant MCA infarction, the latter being equivalent to 8.5% of patients with acute ischemic stroke identified during the same period. Among the patients undergoing DHC, the mean age was 67.0 years, and those ≥60 years of age comprised 80.2% of all DHC patients. The most frequently used modality for vascular imaging was magnetic resonance angiography (77.2%). DHC generally was performed between 24 and 48 hours after onset (38.9%), with 36.9% of patients undergoing surgery at ≥48 hours. At the time of surgery, 26.1% of the patients had a Glasgow Coma Scale score of ≤6. Presurgical midbrain compression was noted in 52.1% of the patients. The 30-day mortality after DHC was 18.6%, and factors affecting death were a Glasgow Coma Scale score of ≤6 (odds ratio [OR] 1.88, 95% confidence interval [95% CI] 1.05-3.32, P = 0.03) and midbrain compression (OR 2.28, 95% CI 1.31-4.09, P = 0.005). According to the multivariate analysis, only midbrain compression was an independent risk factor (OR 2.12, 95% CI 1.16-3.95, P = 0.01) for 30-day mortality. Modified Rankin scale scores at 3 months were available in 175 patients (49.3%), only 5.2% of whom exhibited a favorable functional outcome (mRS score ≤3). Meanwhile, 22.9% of the patients had an mRS score of 4, 26.9% had an mRS score of 5, and 45.1% were found to have died. CONCLUSIONS In the present study, less than one-tenth of candidates with malignant MCA infarction in Japan underwent decompressive surgery, and the vast majority of patients were elderly. Age was not found to be an independent factor for immediate mortality in this study, and performing surgery in the elderly may be justified based on additional evidence of functional improvements.

Abstract
Promising advances in stroke medicine have been reported recently regarding specialized stroke unit (SU) care, expansion of the time window of iv thrombolysis (IVT), mechanical thrombectomy (MT), and decompressive hemicraniectomy (DHC) for malignant brain infarction. It remains unclear to what extent new evidence of therapeutic procedures is transferred to the "real-world" of everyday hospital care. We analyzed epidemiologic and procedural therapeutic trends of hospitalized acute stroke patients in Germany by the comparison of administrative hospital data of the years 2008 (n=219,359) and 2012 (n=239,394). Proportion of specialized SU care rose from 43.4% to 56.9%. Even in age-matched analysis women were less likely to obtain this procedure. Rate of IVT increased from 5.6% to 10.2%. 32% of IVT therapies in 2012 were performed in patients over 80 years. Number of MT increased exponentially from 298 to 3906 procedures. Number of DHC did not increase significantly (2008=636; 2011=796). A strong momentum in transferring scientific insights to the "real-world" stroke care in Germany was documented. Increase of IVT therapy is largely due to the increase of off-label treatment. Almost every 46 th patient <80 years was treated by MT in 2012. Despite proven benefits in selected patients, utilization of DHC remained almost stable.

Abstract
BACKGROUND Titanium cranioplasty (TC) has been associated with high complication rates, but abundant data are lacking. We aimed to determine the incidence and type of complications following TC and risk factors for complications. METHODS A retrospective review was performed on 174 patients who underwent TC at two London units over a seven year period. Data were collected on demographics, primary pathology, perioperative details, complications and functional outcome. Skull defect size was estimated using 3-dimensional computed tomographic reconstructions. RESULTS The overall complication rate was 26.4 % (46/174), and plate removal rate10.3 % (18/174). The commonest complication was infection, which accounted for 69 % of plate removals. Patients who had undergone craniectomy for trauma had a higher complication rate (35 vs 21 %; p = 0.043) and plate removal rate (16 vs 7 %; p = 0.049) than others. There was a non-significant trend towards the association of craniectomy-to-cranioplasty interval of 4-8 months with the lowest complication rate and shortest postoperative hospital stay. Patients with a skull defect larger than 100 cm(2) had the highest complication rate (p < 0.001), highest plate removal rate (p = 0.039), and longest postoperative hospital stay (p = 0.019). Bifrontal versus unilateral cranioplasty was associated with a significantly higher complication rate (40 vs 14 %) and length of hospital stay (5.0 vs 2.9 days). There was no perioperative mortality and no change between pre-operative and post-operative functional outcome. CONCLUSION In the largest UK study on cranioplasty to date, we have demonstrated that size of defect, traumatic aetiology and bifrontal insertion are risk factors for complications. Our results suggest that the timing of cranioplasty may be important with late (> 12 months) TC associated with a higher rate of complications, although further prospective studies on the optimal timing of TC are required to establish the observed trend. Our data can help clinicians stratify risk to inform the consent process and aid pre-operative planning.

Abstract
Malignant middle cerebral artery infarction is a life-threatening sub-type of ischemic stroke that may only be survived at the expense of permanent disability. Decompressive hemicraniectomy is an effective surgical therapy to reduce mortality and improve functional outcome without promoting most severe disability. Evidence derives from three European randomized controlled trials in patients up to 60 years. The recently finished DEcompressive Surgery for the Treatment of malignant INfarction of the middle cerebral arterY - II trial gives now high-level evidence for the effectiveness of decompressive hemicraniectomy in patients older than 60 years. Nevertheless, pressing issues persist that need to be answered in future clinical trials, e.g. the acceptable degree of disability in survivors of malignant middle cerebral artery infarction, the importance of aphasia, and the best timing for decompressive hemicraniectomy. This review provides an overview of the current diagnosis and treatment of malignant middle cerebral artery infarction with a focus on decompressive hemicraniectomy and outlines future perspectives.

Abstract
The debate about exactly when a person dies can benefit from distinguishing the strict biological concept of death from the medical standards for determining death.
