RÉSUMÉ
PURPOSE: Decompressive craniectomy is occasionally performed as a life-saving neurosurgical intervention in patients with acute severe brain injury to reduce refractory intracranial hypertension. Subsequently, cranioplasty (CP) is performed to repair the skull defect. In the meantime, patients are living without cranial bone protection, and little is known about their daily life. This study accordingly explored daily life among patients living without cranial bone protection after decompressive craniectomy while awaiting CP. METHODS: A multiple-case study examined six purposively sampled patients, patients' family members, and healthcare staff. The participants were interviewed and the data were analyzed using qualitative content analysis. RESULTS: The cross-case analysis identified five categories: "Adapting to new ways of living," "Constant awareness of the absence of cranial bone protection," "Managing daily life requires available staff with adequate qualifications," "Impact of daily life depends on the degree of recovery," and "Daily life stuck in limbo while awaiting cranioplasty." The patients living without cranial bone protection coped with daily life by developing new habits and routines, but the absence of cranial bone protection also entailed inconveniences and limitations, particularly among the patients with greater independence in their everyday living. Time spent awaiting CP was experienced as being in limbo, and uncertainty regarding planning was perceived as frustrating. CONCLUSION: The results indicate a vulnerable group of patients with brain damage and communication impairments struggling to find new routines during a waiting period experienced as being in limbo. Making this period safe and reducing some problems in daily life for those living without cranial bone protection calls for a person-centered approach to care involving providing contact information for the correct healthcare institution and individually planned scheduling for CP.

BACKGROUND: Decompressive craniectomy (DC) can alleviate increased intracranial pressure in aneurysmal subarachnoid hemorrhage patients with concomitant space-occupying intracerebral hemorrhage, but also carries a high risk for complications. We studied outcomes and complications of DC at time of ruptured aneurysm repair. METHODS: Of 47 patients treated between 2010 and 2020, 30 underwent DC during aneurysm repair and hematoma evacuation and 17 did not. We calculated odds ratios (OR) for delayed cerebral ischemia (DCI), angiographic vasospasm, DCI-related infarction, and unfavorable functional outcome (extended Glasgow Outcome Scale 1-5) at three months. Complication rates after DC and cranioplasty in the aneurysmal subarachnoid hemorrhage patients were compared to those of all 107 patients undergoing DC for malignant cerebral infarction during the same period. RESULTS: In DC versus no DC patients, proportions were for clinical DCI 37% versus 53% (OR = 0.5;95%CI:0.2-1.8), angiographic vasospasm 37% versus 47% (OR = 0.7;95%CI:0.2-2.2), DCI-related infarctions 17% versus 47% (OR = 0.2;95%CI:0.1-0.7) and unfavorable outcome 80% versus 88% (OR = 0.5;95%CI:0.1-3.0). ORs were similar after adjustment for baseline predictors for outcome. Complications related to DC and cranioplasty occurred in 18 (51%) of subarachnoid hemorrhage patients and 41 (38%) of cerebral infarction patients (OR = 1.7;95%CI:0.8-3.7). CONCLUSIONS: In patients with aneurysmal subarachnoid hemorrhage and concomitant space-occupying intracerebral hemorrhage, early DC was not associated with improved functional outcomes, but with a reduced rate of DCI-related infarctions. This potential benefit has to be weighed against high complication rates of DC in subarachnoid hemorrhage patients.

Our study aimed to evaluate the postoperative outcome of patients with unruptured giant middle cerebral artery (MCA) aneurysm revealed by intracranial hypertension associated to midline brain shift. From 2012 to 2022, among the 954 patients treated by a microsurgical procedure for an intracranial aneurysm, our study included 9 consecutive patients with giant MCA aneurysm associated to intracranial hypertension with a midline brain shift. Deep hypothermic circulatory flow reduction (DHCFR) with vascular reconstruction was performed in 4 patients and cerebral revascularization with aneurysm trapping was the therapeutic strategy in 5 patients. Early (< 7 days) and long term clinical and radiological monitoring was done. Good functional outcome was considered as mRS score ≤ 2 at 3 months. The mean age at treatment was 44 yo (ranged from 17 to 70 yo). The mean maximal diameter of the aneurysm was 49 mm (ranged from 33 to 70 mm). The mean midline brain shift was 8.6 mm (ranged from 5 to 13 mm). Distal MCA territory hypoperfusion was noted in 6 patients. Diffuse postoperative cerebral edema occurred in the 9 patients with a mean delay of 59 h and conducted to a postoperative neurological deterioration in 7 of them. Postoperative death was noted in 3 patients. Among the 6 survivors, early postoperative decompressive hemicraniotomy was required in 4 patients. Good functional outcome was noted in 4 patients. Complete aneurysm occlusion was noted in each patient at last follow-up. We suggest to discuss a systematic decompressive hemicraniotomy at the end of the surgical procedure and/or a partial temporal lobe resection at its beginning to reduce the consequences of the edema reaction and to improve the postoperative outcome of this specific subgroup of patients. A better intraoperative assessment of the blood flow might also reduce the occurrence of the reperfusion syndrome.

BACKGROUND: Decompressive hemicraniectomy (DHC) is used after severe brain damages with elevated, refractory intracranial pressure (ICP). In a non age-restricted population, mortality rates and long-term outcomes following DHC are still unclear. This study's objectives were to examine both, as well as to identify predictors of unfavourable outcomes. METHODS: We undertook a retrospective observational analysis of patients aged 18 years and older who underwent DHC at the University Hospital of Bonn between 2018 and 2020, due to traumatic brain injury (TBI), haemorrhage, tumours or infections. Patient outcomes were assessed by conducting telephone interviews, utilising questionnaires for modified Rankin Scale (mRS) and extended Glasgow Outcome scale (GOSE). We evaluated the health-related quality of life using the EuroQol (EQ-5D-5L) scale. RESULTS: A total of 144 patients with a median age of 58.5 years (range: 18 to 85 years) were evaluated. The mortality rate was 67%, with patients passing away at a median of 6.0 days (IQR [1.9-37.6]) after DHC. Favourable outcomes, as assessed by the mRS and GOSE were observed in 10.4% and 6.3% of patients, respectively. Cox regression analysis revealed a 2.0% increase in the mortality risk for every year of age (HR = 1.017; 95% CI [1.01-1.03]; p = 0.004). Uni- and bilateral fixed pupils were associated with a 1.72 (95% CI [1.03-2.87]; p = 0.037) and 3.97 (95% CI [2.44-6.46]; p < 0.001) times higher mortality risk, respectively. ROC-analysis demonstrated that age and pupillary reactivity predicted 6-month mortality with an AUC of 0.77 (95% CI [0.69-0.84]). The only parameter significantly associated with a better quality of life was younger age. CONCLUSIONS: Following DHC, mortality remains substantial, and favourable outcomes occur rarely. Particularly in elderly patients and in the presence of clinical signs of herniation, mortality rates are notably elevated. Hence, the indication for DHC should be set critically.

BACKGROUND: Decompressive craniectomy (DC) is a surgical procedure to treat refractory increase in intracranial pressure. DC is frequently succeeded by cranioplasty (CP), a reconstructive procedure to protect the underlying brain and maintain cerebrospinal fluid flow dynamics. However, complications such as seizures, fluid collections, infections, and hydrocephalus can arise from CP. Our aim is to investigate these complications and their possible risk factors and to discuss whether early or late CP has any effect on the outcome. MATERIALS AND METHODS: A single-center retrospective cohort study was performed, including patients who underwent CP after DC between January 2014 and January 2022. Relevant information was collected such as demographics, type of brain injury, materials used in CP, timing between DC and CP, and postoperative complications. Ultimately, 63 patients were included in our study. We also compared the complication rate between patients who underwent late CP after DC (>90 days) against patients who underwent early CP (<90 days). RESULTS: Most patients were male (78%). The sample median age was 29 years, with pediatric patients, accounting for 36% of the samples. Overall complication rate was 57% and they were seizure/epilepsy in 50% of the patients, fluid collection (28%), infections (25%), posttraumatic hydrocephalus (17%), and bone defect/resorption (3%). Twenty-two percent of patients with complications required reoperation and underwent a second CP. The median (interquartile range) duration between the craniotomy and the CP was 56 (27-102) days, with an early (≤3 months) percentage of 68%. We found no significant difference between early (≤3 months) and late (>3 months) CP regarding complication rates. CONCLUSION: Despite CP being a simple procedure, it has a considerable rate of complications. Therefore, it is important that surgeons possess adequate knowledge about such complications to navigate these challenges more effectively.
Résumé Contexte:La craniectomie décompressive (DC) est une intervention chirurgicale destinée à traiter l'augmentation réfractaire de la pression intracrânienne. La DC est fréquemment remplacée par une cranioplastie (CP), une procédure reconstructive visant à protéger le cerveau sous-jacent et à maintenir la dynamique du flux du liquide céphalo-rachidien. Cependant, des complications telles que des convulsions, des collections de liquides, des infections et une hydrocéphalie peuvent survenir en raison de la CP. Notre objectif est d'étudier ces complications et leurs facteurs de risque possibles et de discuter si une CP précoce ou tardive a un effet sur le résultat.Matériels et méthodes:Une étude de cohorte rétrospective monocentrique a été réalisée, incluant des patients ayant subi une PC après une DC entre janvier 2014 et janvier 2022. Des informations pertinentes ont été collectées telles que les données démographiques, le type de lésion cérébrale, les matériaux utilisés dans la PC, le timing entre la DC et CP et complications postopératoires. Au final, 63 patients ont été inclus dans notre étude. Nous avons également comparé le taux de complications entre les patients ayant subi une CP tardive après une DC (> 90 jours) et ceux ayant subi une CP précoce (<90 jours).Résultats:La plupart des patients étaient des hommes (78 %). L'âge médian de l'échantillon était de 29 ans, les patients pédiatriques représentant 36 % des échantillons. Le taux global de complications était de 57 % et il s'agissait de convulsions/épilepsie chez 50 % des patients, d'accumulation de liquide (28 %), d'infections (25 %), d'hydrocéphalie post-traumatique (17 %) et de défauts/résorptions osseuses (3 %). Vingtdeux pour cent des patients présentant des complications ont dû être réopérés et ont subi une deuxième CP. La durée médiane (intervalle interquartile) entre la craniotomie et la CP était de 56 (27 à 102) jours, avec un pourcentage précoce (≤ 3 mois) de 68 %. Nous n'avons trouvé aucune différence significative entre la PC précoce (≤ 3 mois) et tardive (> 3 mois) en ce qui concerne les taux de complications.Conclusion:Bien que la CP soit une procédure simple, elle entraîne un taux de complications considérable. Il est donc important que les chirurgiens possèdent des connaissances adéquates sur ces complications pour relever ces défis plus efficacement.

Craniotomy or decompressive craniectomy are among the therapeutic options to prevent or treat secondary damage after severe brain injury. The choice of procedure depends, among other things, on the type and severity of the initial injury. It remains controversial whether both procedures influence the neurological outcome differently. Thus, estimating the risk of brain herniation and death and consequently potential organ donation remains difficult. All patients at the University Hospital Münster for whom an isolated craniotomy or decompressive craniectomy was performed as a treatment after severe brain injury between 2013 and 2022 were retrospectively included. Proportion of survivors and deceased were evaluated. Deceased were further analyzed regarding anticoagulants, comorbidities, type of brain injury, potential and utilized donation after brain death. 595 patients were identified, 296 patients survived, and 299 deceased. Proportion of decompressive craniectomy was higher than craniotomy in survivors (89% vs. 11%, p < 0.001). Brain death was diagnosed in 12 deceased and 10 donations were utilized. Utilized donations were comparable after both procedures (5% vs. 2%, p = 0.194). Preserved brain stem reflexes as a reason against donation did not differ between decompressive craniectomy or craniotomy (32% vs. 29%, p = 0.470). Patients with severe brain injury were more likely to survive after decompressive craniectomy than craniotomy. Among the deceased, potential and utilized donations did not differ between both procedures. This suggests that brain death can occur independent of the previous neurosurgical procedure and that organ donation should always be considered in end-of-life decisions for patients with a fatal prognosis.

BACKGROUND: This study aims to investigate the benefits of employing a Physical Lifelike Brain (PLB) simulator for training medical students in performing craniotomy for glioblastoma removal and decompressive craniectomy. METHODS: This prospective study included 30 medical clerks (fifth and sixth years in medical school) at a medical university. Before participating in the innovative lesson, all students had completed a standard gross anatomy course as part of their curriculum. The innovative lesson involved PLB Simulator training, after which participants completed the Learning Satisfaction/Confidence Perception Questionnaire and some received qualitative interviews. RESULTS: The average score of students' overall satisfaction with the innovative lesson was 4.71 out of a maximum of 5 (SD = 0.34). After the lesson, students' confidence perception level improved significantly (t = 9.38, p < 0.001, effect size = 1.48), and the average score improved from 2,15 (SD = 1.02) to 3.59 (SD = 0.93). 60% of the students thought that the innovative lesson extremely helped them understand the knowledge of surgical neuroanatomy more, 70% believed it extremely helped them improve their skills in burr hole, and 63% thought it was extremely helpful in improving the patient complications of craniotomy with the removal of glioblastoma and decompressive craniectomy after completing the gross anatomy course. CONCLUSION: This innovative lesson with the PLB simulator successfully improved students' craniotomy knowledge and skills.

Giant ruptured distal anterior cerebral artery aneurysms are rare, challenging pathologies that may require a combination of microsurgical and endovascular techniques for optimal treatment [1-9]. We describe the case of a female in her 40â¯s who presented with a Hunt-Hess 4, Fisher 4 subarachnoid hemorrhage from a multiply ruptured, giant distal anterior cerebral artery aneurysm. The patient underwent coil and n-BCA glue embolization of the aneurysm and its feeding A2 anterior cerebral artery. She subsequently underwent decompressive craniectomy, intracerebral hematoma evacuation, and microsurgical trapping and resection of the aneurysm. Postoperative imaging demonstrated no further aneurysm filling, complete hematoma evacuation, and good decompression. The technical considerations and literature for the combined treatment of large and giant ruptured aneurysms are reviewed. The case presentation, operative nuances, and postoperative course with imaging are reviewed with detailed anatomical diagrams to orient the viewer. The patient consented to the procedure and to the publication of her imaging.

raumatic brain injury (TBI) is a significant global health concern, particularly affecting young individuals, and is a leading cause of mortality and morbidity worldwide. Despite improvements in treatment infrastructure, many TBI patients choose discharge against medical advice (DAMA), often declining necessary surgical interventions. We aimed to investigate the factors that can be associated with DAMA in TBI patients that were recommended to have surgical treatment. This study was conducted at single tertiary university center (2008-2018), by retrospectively reviewing 1510 TBI patients whom visited the emergency room. We analyzed 219 TBI surgical candidates, including 50 declining surgery (refused group) and the others whom agreed and underwent decompressive surgery. Retrospective analysis covered demographic characteristics, medical history, insurance types, laboratory results, CT scan findings, and GCS scores. Statistical analyses identified factors influencing DAMA. Among surgical candidates, 169 underwent surgery, while 50 declined. Age (60.8 ± 17.5 vs. 70.5 ± 13.8 years; p < 0.001), use of anticoagulating medication (p = 0.015), and initial GCS scores (9.0 ± 4.3 vs. 5.3 ± 3.2; p < 0.001) appeared to be associated with refusal of decompressive surgery. Based on our analysis, factors influencing DAMA for decompressive surgery included age, anticoagulant use, and initial GCS scores. Contrary to general expectations and some previous studies, our analysis revealed that the patients' medical conditions had a larger impact than socioeconomic status under the Korean insurance system, which fully covers treatment for TBI. This finding provides new insights into the factors affecting DAMA and could be valuable for future administrative plans involving national insurance.

BACKGROUND: Acute subdural hematoma (ASDH) necessitates urgent surgical intervention. Craniotomy (CO) and decompressive craniectomy (DC) are the two main surgical procedures for ASDH evacuation. This meta-analysis is to compare the clinical outcomes between the CO and DC procedures. MATERIALS AND METHODS: The authors performed a meta-analysis according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA, Supplemental Digital Content 1, http://links.lww.com/JS9/C513 , Supplemental Digital Content 2, http://links.lww.com/JS9/C514 ) Statement protocol and assessing the methodological quality of systematic reviews (AMSTAR) (Supplemental Digital Content 3, http://links.lww.com/JS9/C515 ) guideline. The PubMed, Embase, Web of Science, and Cochrane Library databases were systematically searched. Comparative studies reporting the outcomes of the CO and DC procedures in patients with ASDH were included. RESULTS: A total of 15 articles with 4853 patients [2531 (52.2%) receiving CO and 2322 (47.8%) receiving DC] were included in this meta-analysis. DC was associated with higher mortality [31.5 vs. 40.6%, odds ratio (OR)=0.58, 95% CI: 0.43-0.77] and rate of patients with poorer neurological outcomes (54.3 vs. 72.7%; OR=0.43, 95% CI: 0.28-0.67) compared to CO. The meta-regression model identified the comparability of preoperative severity as the only potential source of heterogeneity. When the preoperative severity was comparable between the two procedures, the mortality (CO 35.5 vs. DC 38.1%, OR=0.80, 95% CI: 0.62-1.02) and the proportion of patients with poorer neurological outcomes (CO 64.8 vs. DC 66.0%; OR=0.82, 95% CI: 0.57-1.16) were both similar. Reoperation rates were similar between the two procedures (CO 16.1 vs. DC 16.0%; OR=0.95, 95% CI: 0.61-1.48). CONCLUSION: Our meta-analysis reveals that DC is associated with higher mortality and poorer neurological outcomes in ASDH compared to CO. Notably, this difference in outcomes might be driven by baseline patient severity, as the significance of surgical choice diminishes after adjusting for this factor. Our findings challenge previous opinions regarding the superiority of CO over DC and underscore the importance of considering patient-specific characteristics when making surgical decisions. This insight offers guidance for surgeons in making decisions tailored to the specific conditions of their patients.

OBJECTIVE: To estimate the cost-effectiveness of craniotomy, compared with decompressive craniectomy (DC) in UK patients undergoing evacuation of acute subdural haematoma (ASDH). DESIGN: Economic evaluation undertaken using health resource use and outcome data from the 12-month multicentre, pragmatic, parallel-group, randomised, Randomised Evaluation of Surgery with Craniectomy for Patients Undergoing Evacuation-ASDH trial. SETTING: UK secondary care. PARTICIPANTS: 248 UK patients undergoing surgery for traumatic ASDH were randomised to craniotomy (N=126) or DC (N=122). INTERVENTIONS: Surgical evacuation via craniotomy (bone flap replaced) or DC (bone flap left out with a view to replace later: cranioplasty surgery). MAIN OUTCOME MEASURES: In the base-case analysis, costs were estimated from a National Health Service and Personal Social Services perspective. Outcomes were assessed via the quality-adjusted life-years (QALY) derived from the EuroQoL 5-Dimension 5-Level questionnaire (cost-utility analysis) and the Extended Glasgow Outcome Scale (GOSE) (cost-effectiveness analysis). Multiple imputation and regression analyses were conducted to estimate the mean incremental cost and effect of craniotomy compared with DC. The most cost-effective option was selected, irrespective of the level of statistical significance as is argued by economists. RESULTS: In the cost-utility analysis, the mean incremental cost of craniotomy compared with DC was estimated to be -£5520 (95% CI -£18 060 to £7020) with a mean QALY gain of 0.093 (95% CI 0.029 to 0.156). In the cost-effectiveness analysis, the mean incremental cost was estimated to be -£4536 (95% CI -£17 374 to £8301) with an OR of 1.682 (95% CI 0.995 to 2.842) for a favourable outcome on the GOSE. CONCLUSIONS: In a UK population with traumatic ASDH, craniotomy was estimated to be cost-effective compared with DC: craniotomy was estimated to have a lower mean cost, higher mean QALY gain and higher probability of a more favourable outcome on the GOSE (though not all estimated differences between the two approaches were statistically significant). ETHICS: Ethical approval for the trial was obtained from the North West-Haydock Research Ethics Committee in the UK on 17 July 2014 (14/NW/1076). TRIAL REGISTRATION NUMBER: ISRCTN87370545.

AIM: To evaluate the relationship between the surgical techniques, the waiting time for surgery, postoperative distance between the graft-bone margin and the percentage of bone resorption, we analyzed patients who underwent cranioplasty. Cranioplasty is a necessary surgery to preserve brain tissue and provide an appropriate microenvironment. MATERIAL AND METHODS: In this study, patients who underwent autologous bone grafting after decompressive craniectomy by the Neurosurgery Clinic of University of Health Sciences Ankara Training and Research Hospital between 2018 and 2021 were examined. RESULTS: Thirty-nine patients who underwent autologous cranioplasty following decompressive craniectomy were included in the study. The average expected time for cranioplasty surgery following decompressive craniectomy was 16.97±13.478 weeks (min:2 max:62 weeks). The expected time between decompressive craniectomy and cranioplasty surgeries and resorption rates were compared. The resorption rate was above 30% in 7 of 10 patients with 24 weeks or more between craniectomy and cranioplasty, and less than 30% in 17 of 25 patients in surgeries less than 24 weeks (p=0.04). Following cranioplasty surgery, the distance between the graft-bone margin and the resorption rates were also compared. In this analysis, statistically significant differences were detected between the distance between the graft-bone border and the resorption rates. Resorption rates increased in 15 of 19 patients with a postcranioplasty distance of 1 mm or more (p < 0.00001). CONCLUSION: Early cranioplasty surgery is important in order to reduce complications that may occur after craniectomy. In addition, it is important to keep the defect area small in size during craniectomy surgery and to keep the cutting edge thinner when the bone graft is taken, in order to reduce the development of bone graft resorption.

BACKGROUND: Acute subdural hematoma (ASDH) is a life-threatening condition, and hematoma removal is necessary as a lifesaving procedure when the intracranial pressure is highly elevated. However, whether decompressive craniectomy (DC) or conventional craniotomy (CC) is adequate remains unclear. Hinge craniotomy (HC) is a technique that provides expansion potential for decompression while retaining the bone flap. At our institution, HC is the first-line operation instead of DC for traumatic ASDH, and we present the surgical outcomes. METHODS: From January 1, 2017, to December 31, 2022, 372 patients with traumatic ASDH were admitted to our institution, among whom 48 underwent hematoma evacuation during the acute phase. HC was performed in cases where brain swelling was observed intraoperatively. If brain swelling was not observed, CC was selected. DC was performed only when the brain was too swollen to allow replacement of the bone flap. We conducted a retrospective analysis of patient demographics, prognosis, and subsequent cranial procedures for each technique. RESULTS: Of the 48 patients, 2 underwent DC, 23 underwent HC, and 23 underwent CC. The overall mortality rate was 20.8% (10/48) at discharge and 30.0% (12/40) at 6 months. The in-hospital mortality rates for DC, HC, and CC were 100% (2/2), 21.7% (5/23), and 13.0% (3/23), respectively. Primary brain injury was the cause of death in five patients whose brainstem function was lost immediately after surgery. No fatalities were attributed to the progression of postoperative brain herniation. In only one case, the cerebral contusion worsened after the initial surgery, leading to brain herniation and necessitating secondary DC. CONCLUSIONS: The strategy of performing HC as the first-line operation for ASDH did not increase the mortality rate compared with past surgical reports and required secondary DC in only one case.

Cranial repair in children deserves particular attention since many issues are still controversial. Furthermore, literature data offer a confused picture of outcome of cranioplasty, in terms of results and complication rates, with studies showing inadequate follow-up and including populations that are not homogeneous by age of the patients, etiology, and size of the bone defect.Indeed, age has merged in the last years as a risk factor for resorption of autologous bone flap that is still the most frequent complication in cranial repair after decompressive craniectomy.Age-related factors play a role also when alloplastic materials are used. In fact, the implantation of alloplastic materials is limited by skull growth under 7 years of age and is contraindicated in the first years if life. Thus, the absence of an ideal material for cranioplasty is even more evident in children with a steady risk of complications through the entire life of the patient that is usually much longer than surgical follow-up.As a result, specific techniques should be adopted according to the age of the patient and etiology of the defect, aiming to repair the skull and respect its residual growth.Thus, autologous bone still represents the best option for cranial repair, though limitations exist. As an alternative, biomimetic materials should ideally warrant the possibility to overcome the limits of other inert alloplastic materials by favoring osteointegration or osteoinduction or both.On these grounds, this paper aims to offer a thorough overview of techniques, materials, and peculiar issues of cranial repair in children.

PURPOSE: Surgical site infection (SSI) is a serious complication after cranioplasty. Due to the relatively frequent occurrence of post-cranioplasty SSI, the utility of autologous bone flap swab cultures surrounding cryopreservation as a reliable predictor has been the subject of an ongoing debate. This bicentric study aims to contribute to this topic by conducting an in-depth analysis of bone flaps obtained via decompressive craniectomies. This study had three major aims: assessments of 1) bacterial contamination of bone flaps after decompressive craniotomy, 2) impact of cryoconservation on contamination rates and 3) potential effectiveness of anti-infective treatment to reduce the germ load prior to cranioplasty. METHODS: Cryopreserved bone flaps from two centers were used. Microbiological cultivations of swabs prior to and after cryopreservation were taken and assessed for aerobic and anaerobic growth over a 14-day incubation period. Additionally, in a subset of bone flaps, swab testing was repeated after thorough rinsing with an anti-infectant (octenidine-phenoxyethanol) followed by saline. RESULTS: All 63 bone flaps (patients median age at surgery: 59 years) were obtained via decompressive craniectomies. Swabs done prior to cryopreservation revealed a 54% infection rate with Propionibacterium acnes being the most common microorganism in 65% of those cases. After thorough disinfection of the preserved bone flaps, all but one case showed no bacterial growth in swab testing. Furthermore, no relevant risk factors for bacterial contamination could be identified. CONCLUSION: This retrospective study showed the common presence of bacterial growth in cryopreserved bone flaps before and after freezing. Rinsing with octenidine-phenoxyethanol and saline effectively prevented bacterial growth in a notable percentage of cases, suggesting a potential strategy to reduce contamination. However, persistent bacterial growth in some cases underscores the need for further research to optimize antiseptic measures during autologous cranioplasty.

INTRODUCTION: Acute subdural hematoma (ASDH), a predominantly lethal neurosurgical emergency in the settings of traumatic brain injury, requires surgical evacuation of hematoma, via craniotomy or craniectomy. The clinical practices vary, with no consensus over the superiority of either procedure. AIM: To evaluate whether craniotomy or craniectomy is the optimal approach for surgical evacuation of ASDH. METHODS: After a comprehensive search of PubMed, Google Scholar, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) up to January 2024, to identify relevant studies, a meta-analysis was performed using a random-effects model, and risk ratios were calculated with 95% confidence intervals (CIs). For quality assessment, the Cochrane risk of bias tool and Newcastle-Ottawa Scale were applied. RESULTS: Out of 2143 potentially relevant studies, 1875 were deemed suitable for screening. Eighteen studies were included in the systematic review. Thirteen studies, in which 1589 patients underwent craniotomy and 1452 patients underwent craniectomy, allowed meta-analysis. Pooled estimates showed that there was no significant correlation of mortality at 6 months (RR 1.14;95 % CI; 0.94-1.38 P = 0.18) and 12 months (RR 1.17; 95 % CI; 0.84-1.63 P = 0.36) with the two surgical modalities. A positive association was observed between improved functional outcomes at 6-months and craniotomy (RR 0.76; 95 % CI; 0.62-0.93 P = 0.008), however, no significant difference was observed between the two treatment groups at 12 months follow-up (RR 0.89; 95 % CI; 0.72-1.09 P = 0.26). Craniotomy reported a significantly higher proportion of patients discharged to home (RR 0.63; 95 % CI; 0.49-0.83 P = 0.0007), whereas incidence of residual subdural hematoma was significantly lower in the craniectomy group (RR 0.70; 95 % CI; 0.52-0.94 P = 0.02). CONCLUSION: Craniectomy is associated with poor clinical outcomes. However, with long-term follow-up, no difference in mortality and functional outcomes is observed in either of the patient populations. On account of equivocal evidence regarding the efficacy of craniectomy over craniotomy in the realm of long-term outcomes, utmost preference shall be directed toward craniotomy as it is less invasive and associated with fewer complications.

PURPOSE: Progressive cerebral edema with refractory intracranial hypertension (ICP) requiring decompressive hemicraniectomy (DHC) is a severe manifestation of early brain injury (EBI) after aneurysmal subarachnoid hemorrhage (aSAH). The purpose of the study was to investigate whether a more pronounced cerebrospinal fluid (CSF) drainage has an influence on cerebral perfusion pressure (CPP) and the extent of EBI after aSAH. METHODS: Patients with aSAH and indication for ICP-monitoring admitted to our center between 2012 and 2020 were retrospectively included. EBI was categorized based on intracranial blood burden, persistent loss of consciousness, and SEBES (Subarachnoid Hemorrhage Early Brain Edema Score) score on the third day after ictus. The draining CSF and vital signs such as ICP and CPP were documented daily. RESULTS: 90 out of 324 eligible aSAH patients (28%) were included. The mean age was 54.2 ± 11.9 years. DHC was performed in 24% (22/90) of patients. Mean CSF drainage within 72 h after ictus was 168.5 ± 78.5 ml. A higher CSF drainage within 72 h after ictus correlated with a less severe EBI and a less frequent need for DHC (r=-0.33, p = 0.001) and with a higher mean CPP on day 3 after ictus (r = 0.2351, p = 0.02). CONCLUSION: A more pronounced CSF drainage in the first 3 days of aSAH was associated with higher CPP and a less severe course of EBI and required less frequently a DHC. These results support the hypothesis that an early and pronounced CSF drainage may facilitate blood clearance and positively influence the course of EBI.
