ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

BACKGROUND: It is unknown whether decompressive craniectomy improves clinical outcome for people with spontaneous severe deep intracerebral haemorrhage. The SWITCH trial aimed to assess whether decompressive craniectomy plus best medical treatment in these patients improves outcome at 6 months compared to best medical treatment alone. METHODS: In this multicentre, randomised, open-label, assessor-blinded trial conducted in 42 stroke centres in Austria, Belgium, Finland, France, Germany, the Netherlands, Spain, Sweden, and Switzerland, adults (18-75 years) with a severe intracerebral haemorrhage involving the basal ganglia or thalamus were randomly assigned to receive either decompressive craniectomy plus best medical treatment or best medical treatment alone. The primary outcome was a score of 5-6 on the modified Rankin Scale (mRS) at 180 days, analysed in the intention-to-treat population. This trial is registered with ClincalTrials.gov, NCT02258919, and is completed. FINDINGS: SWITCH had to be stopped early due to lack of funding. Between Oct 6, 2014, and April 4, 2023, 201 individuals were randomly assigned and 197 gave delayed informed consent (96 decompressive craniectomy plus best medical treatment, 101 best medical treatment). 63 (32%) were women and 134 (68%) men, the median age was 61 years (IQR 51-68), and the median haematoma volume 57 mL (IQR 44-74). 42 (44%) of 95 participants assigned to decompressive craniectomy plus best medical treatment and 55 (58%) assigned to best medical treatment alone had an mRS of 5-6 at 180 days (adjusted risk ratio [aRR] 0·77, 95% CI 0·59 to 1·01, adjusted risk difference [aRD] -13%, 95% CI -26 to 0, p=0·057). In the per-protocol analysis, 36 (47%) of 77 participants in the decompressive craniectomy plus best medical treatment group and 44 (60%) of 73 in the best medical treatment alone group had an mRS of 5-6 (aRR 0·76, 95% CI 0·58 to 1·00, aRD -15%, 95% CI -28 to 0). Severe adverse events occurred in 42 (41%) of 103 participants receiving decompressive craniectomy plus best medical treatment and 41 (44%) of 94 receiving best medical treatment. INTERPRETATION: SWITCH provides weak evidence that decompressive craniectomy plus best medical treatment might be superior to best medical treatment alone in people with severe deep intracerebral haemorrhage. The results do not apply to intracerebral haemorrhage in other locations, and survival is associated with severe disability in both groups. FUNDING: Swiss National Science Foundation, Swiss Heart Foundation, Inselspital Stiftung, and Boehringer Ingelheim.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

A young miniature poodle was presented following blunt force trauma to the head. The dog initially responded well to medical management before developing clinical signs associated with increased intracranial pressure 48 h post-injury that became refractory to hyperosmolar therapy. A computed tomography scan obtained 76 h post-injury showed a short, oblique, non-displaced, complete fissure in the right temporal bone and a second short, oblique, non-displaced, complete fissure in the ventral aspect of the temporal bone. A biconvex, moderately hyperattenuating, space-occupying temporoparietal lesion was visualized immediately adjacent to the area of the temporal fractures. These findings were consistent with a diagnosis of intracranial extradural hematoma. Decompressive craniectomy successfully evacuated the extradural hematoma to alleviate increased intracranial pressure. The dog's neurologic function recovered quickly postoperatively. At follow-up physical examinations at 14 and 437 d, excellent return to function was noted. Key clinical message: This report describes the diagnosis and surgical management of an intracranial extradural hematoma in a dog with increased intracranial pressure refractory to medical management. Furthermore, this report describes the diagnostic imaging findings used to diagnose this particular form of primary brain injury.


Chirurgie de craniectomie décompressive chez un chien présentant un hématome extradural intracrânien à la suite d'un traumatisme contondant. Un jeune caniche miniature a été présenté à la suite d'un traumatisme contondant à la tête. Le chien a initialement bien répondu à la prise en charge médicale avant de développer des signes cliniques associés à une augmentation de la pression intracrânienne 48 heures après la blessure, qui sont devenus réfractaires au traitement hyperosmolaire. Une tomodensitométrie obtenue 76 heures après la blessure a montré une fissure complète courte, oblique, non déplacée dans l'os temporal droit et une deuxième fissure complète courte, oblique, non déplacée dans la face ventrale de l'os temporal. Une lésion temporo-pariétale biconvexe, modérément hyperatténuée et occupant de l'espace a été visualisée immédiatement à côté de la zone des fractures temporales. Ces résultats concordaient avec un diagnostic d'hématome extradural intracrânien. La craniectomie décompressive a réussi à évacuer l'hématome extradural pour atténuer l'augmentation de la pression intracrânienne. La fonction neurologique du chien s'est rétablie rapidement après l'opération. Lors des examens physiques de suivi à 14 et 437 jours, un excellent retour au fonctionnement a été noté.Message clinique clé:Ce rapport décrit le diagnostic et la prise en charge chirurgicale d'un hématome extradural intracrânien chez un chien présentant une augmentation de la pression intracrânienne réfractaire à la prise en charge médicale. En outre, ce rapport décrit les résultats de l'imagerie diagnostique utilisée pour diagnostiquer cette forme particulière de lésion cérébrale primaire.(Traduit par Dr Serge Messier).

ABSTRACT

The "Letter to the Editor" titled "Scalp incision technique for decompressive hemicraniectomy: comparative systematic review and meta-analysis of the reverse question mark versus alternative retroauricular and Kempe incision techniques of published cases" provides a detailed analysis of different scalp incision techniques in decompressive hemicraniectomy procedures. While commendable for its systematic approach and valuable insights, the letter has several limitations, including a lack of transparency in the search strategy, failure to address potential sources of bias, and a narrow focus on technical aspects without considering broader outcome domains and practical considerations. Despite these limitations, the letter underscores the importance of evidence-based decision-making in neurosurgical practice and calls for further research to address these gaps.

ABSTRACT

BACKGROUND: Patient's age is considered to be one of the most relevant factors in selecting surgical candidates for decompressive hemicraniectomy after malignant hemispheric infarction. However, questions about surgical indication in older patients, patients with consciousness disorder or patients with large infarctions remain unanswered. OBJECTIVE: Our aim was to design a multifactorial scoring scale based on a combination of patient-specific factors in order to optimize the assessment of prognosis in patients after hemicraniectomy malignant strokes. METHODS: In this prospective observational study with a one-year follow-up, we assessed clinical and imaging data of patients who underwent decompressive hemicraniectomy due to malignant brain infarction. Barthel index was used as a single outcome measure to distinguish favorable vs. unfavorable outcomes. Associations between multiple variables and clinical outcome were assessed. Subsequently, a design of a predictive scoring system was proposed. RESULTS: Age of the patient, preoperative level of consciousness, midline shift, and volume of infarction showed a significant association with postoperative Barthel index. According to the identified factors, a multifactorial prognostic scoring system was introduced, aimed to distinguish between favorable and unfavorable outcomes. Using ROC analysis, it has achieved an AUC of 0.74 (95%CI 0.58‒0.89, p=0.01)CONCLUSIONS: Prediction of postoperative outcome should be based on multiple variables. Our scale, based on the clinical and imaging data, can be used during decision-making to estimate potential benefit of decompressive craniectomy in patients after malignant brain infarction (Tab. 5, Fig. 1, Ref. 32).

ABSTRACT

BACKGROUND: The Cisternostomy is a novel surgical concept in the treatment of Traumatic Brain Injury (TBI), which can effectively drain the bloody cerebrospinal fluid from the skull base cistern, reduce the intracranial pressure, and improve the return of bone flap, but its preventive role in post-traumatic hydrocephalus (PTH) is unknow. The purpose of this paper is to investigate whether Cisternostomy prevents the occurrence of PTH in patients with moderate and severe TBI. METHODS: A retrospective analysis of clinical data of 86 patients with moderate and severe TBI from May 2019 to October 2021 was carried out in the Brain Trauma Center of Tianjin Huanhu Hospital. Univariate analysis was performed to examine the gender, age, preoperative Glasgow Coma Scale (GCS) score, preoperative Rotterdam CT score, decompressive craniectomy rate, intracranial infection rate, the incidence of subdural fluid, and incidence of hydrocephalus in patients between the Cisternostomy group and the non-Cisternostomy surgery group. we also analyzed the clinical outcome indicators like GCS at discharge,6 month GOS-E and GOS-E ≥ 5 in two groups.Additionaly, the preoperative GCS score, decompressive craniectomy rate, age, and gender of patients with PTH and non hydrocephalus were compared. Further multifactorial logistic binary regression was performed to explore the risk factors for PTH. Finally, we conducted ROC curve analysis on the statistically significant results from the univariate regression analysis to predict the ability of each risk factor to cause PTH. RESULTS: The Cisternostomy group had a lower bone flap removal rate(48.39% and 72.73%, p = 0.024)., higer GCS at discharge(11.13 ± 2.42 and 8.93 ± 3.31,p = 0.000) and better 6 month GOS-E(4.55 ± 1.26 and 3.95 ± 1.18, p = 0.029)than the non-Cisternostomy group However, there was no statistical difference in the incidence of hydrocephalus between the two groups (25.81% and 30.91%, p = 0.617). Moreover, between the hydrocephalus group and no hydrocephalus group,there were no significant differences in the incidence of gender, age, intracranial infection, and subdural fluid. While there were statistical differences in peroperative GCS score, Rotterdam CT score, decompressive craniectomy rate, intracranial infection rate, and the incidence of subdural fluid in the two groups, there was no statistical difference in the percentage of cerebral cisterns open drainage between the hydrocephalus group and no hydrocephalus group (32.00% and 37.70%, p = 0.617). Multifactorial logistic binary regression analysis results revealed that the independent risk factors for PTH were intracranial infection (OR = 18.460, 95% CI: 1.864-182.847 p = 0.013) and subdural effusion (OR = 10.557, 95% CI: 2.425-35.275 p = 0.001). Further, The ROC curve analysis showed that peroperative GCS score, Rotterdam CT score and subdural effusion had good ACU(0.785,0.730,and 0.749), with high sensitivity and specificity to predict the occurrence of PTH. CONCLUSIONS: Cisternostomy may decrease morbidities associated with removal of the bone flap and improve the clinical outcome, despite it cannot reduce the disability rate in TBI patients.Intracranial infection and subdural fluid were found to be the independent risk factors for PTH in patients with TBI,and the peroperative GCS score, Rotterdam CT score and subdural effusion had higher sensitivity and specificity to predict the occurrence of PTH. And more importantly, no correlation was observed between open drainage of the cerebral cisterns and the occurrence of PTH, indicating that Cisternostomy may not be beneficial in preventing the occurrence of PTH in patients with moderate and severe TBI.

ABSTRACT

BACKGROUND: The mortality rate of patients with traumatic brain injury (TBI) is still high even while undergoing decompressive craniectomy (DC), and the expensive treatment costs bring huge economic burden to the families of patients. OBJECTIVE: The aim of this study was to identify preoperative indicators that influence patient outcomes and to develop a risk model for predicting patient mortality by a retrospective analysis of TBI patients undergoing DC. METHODS: A total of 288 TBI patients treated with DC, admitted to the First Affiliated Hospital of Shantou University Medical School from August 2015 to April 2021, were used for univariate and multivariate logistic regression analysis to determine the risk factors for death after DC in TBI patients. We also built a risk model for the identified risk factors and conducted internal verification and model evaluation. RESULTS: Univariate and multivariate logistic regression analysis identified four risk factors: Glasgow Coma Scale, age, activated partial thrombin time, and mean CT value of the superior sagittal sinus. These risk factors can be obtained before DC. In addition, we also developed a 3-month mortality risk model and conducted a bootstrap 1000 resampling internal validation, with C-indices of 0.852 and 0.845, respectively. CONCLUSIONS: We developed a risk model that has clinical significance for the early identification of patients who will still die after DC. Interestingly, we also identified a new early risk factor for TBI patients after DC, that is, preoperative mean CT value of the superior sagittal sinus (p < .05).

ABSTRACT

INTRODUCTION: Rates of decompressive craniectomy (DC) in acute ischemic stroke (AIS) have been reported to decline over time, attributed to an increase in endovascular therapy (EVT) preventing the development of malignant cerebral edema. We sought to characterize trends in DC in AIS between 2011 and 2020. MATERIAL AND METHODS: We performed a retrospective observational study of U.S. AIS hospitalizations using the National Inpatient Sample, 2011 to 2020. We calculated rates of DC per 10,000 AIS among all AIS hospitalizations, as well as AIS hospitalizations undergoing invasive mechanical ventilation (IMV). A logistic regression to determine predictors of DC was performed. RESULTS: Of ∼4.4 million AIS hospitalizations, 0.5 % underwent DC; of ∼300,000 AIS with IMV, 5.8 % underwent DC. From 2011 to 2020, the rate of DC increased from 37.4 to 59.1 per 10,000 AIS (p < 0.001). The rate of DC in patients undergoing IMV remained stable at ∼550 per 10,000 (p = 0.088). The most important factors predicting DC were age (OR 4.88, 95 % CI 4.53-5.25), hospital stroke volume (OR 2.61, 95 % CI 2.17-3.14), hospital teaching status (OR 1.54, 95 % CI 1.36-1.75), and transfer status (OR 1.53, 95 % CI 1.41-1.66); EVT status did not predict DC. CONCLUSIONS: The rate of DC in AIS has increased between 2011 and 2020. Our findings are contrary to prior reports of decreasing DC rates over time. Increasing EVT rates do not seem to be preventing the occurrence of DC. Future research should focus on the decision-making process for both clinicians and surrogates regarding DC with consideration of long-term outcomes.

ABSTRACT

INTRODUCTION: Bone flap replacement after a decompressive craniectomy is a low complexity procedure, but with complications that can negatively impact the patient's outcome. A better knowledge of the risk factors for these complications could reduce their incidence. PATIENTS AND METHODS: A retrospective review of a series of 50 patients who underwent bone replacement after decompressive craniectomy at a tertiary center over a 10-year period was performed. Those clinical variables related to complications after replacement were recorded and their risk factors were analyzed. RESULTS: A total of 18 patients (36%) presented complications after bone flap replacement, of which 10 (55.5%) required a new surgery for their treatment. Most of the replacements (95%) were performed in the first 90 days after the craniectomy, with a tendency to present more complications compared to the subsequent period (37.8% vs 20%, p > 0.05). The most frequent complication was subdural hygroma, which appeared later than infection, the second most frequent complication. The need for ventricular drainage or tracheostomy and the mean time on mechanical ventilation, ICU admission, or waiting until bone replacement were greater in patients who presented post-replacement complications. Previous infections outside the nervous system or the surgical wound was the only risk factor for post-bone flap replacement complications (p = 0.031). CONCLUSIONS: Postoperative complications were recorded in more than a third of the patients who underwent cranial bone flap replacement, and at least half of them required a new surgery. A specific protocol aimed at controlling previous infections could reduce the risk of complications and help establish the optimal time for cranial bone flap replacement.

ABSTRACT

A 50-year-old man presented with mild unconsciousness after a fall-induced head injury. Initial imaging revealed a left-sided acute subdural hematoma. After transportation to our hospital, his condition deteriorated, leading to the discovery of a new hemorrhage and an anterior falcine artery aneurysm upon further examination. The patient underwent successful decompressive craniectomy and endovascular occlusion. This case, the first reported of a traumatic anterior falcine artery aneurysm, suggests the initial injury caused both the hematoma and aneurysm. The aneurysm's specific location near the crista galli likely contributed to the formation of the traumatic aneurysm, and the compression of the left frontal lobe by the acute subdural hematoma caused the subsequent hemorrhage. This case highlights the importance of considering traumatic aneurysms in atypical postinjury hemorrhages and adds to the understanding of traumatic intracranial aneurysms' mechanisms.

ABSTRACT

PURPOSE: Surgical resection with bony margins would be the treatment of choice for tumours with osseous involvement such as meningiomas and metastasis. By developing and designing pre-operative customised 3D modelled implants, the patient can undergo resection of meningioma and repair of bone defect in the same operation. We present a generalisable method for designing pre-operative cranioplasty in patients to repair the bone defect after the resection of tumours. MATERIALS AND METHODS: We included six patients who presented with a tumour that was associated with overlying bone involvement. They underwent placement of customised cranioplasty in the same setting. A customised implant using a pre-operative imaging was designed with a 2-cm margin to allow for any intra-operative requirements for extending the craniectomy. RESULTS: Six patients were evaluated in this case series. Four patients had meningiomas, 1 patient had metastatic breast cancer on final histology, and 1 patient was found to have an intra-osseous arteriovenous malformation. Craniectomy based on margins provided by a cutting guide was fashioned. After tumour removal and haemostasis, the cranioplasty was then placed. All patients recovered well post-operatively with satisfactory cosmetic results. No wound infection was reported in our series. CONCLUSION: Our series demonstrate the feasibility of utilising pre-designed cranioplasty for meningiomas and other tumours with osseous involvement. Following strict infection protocols, minimal intra-operative handling/modification of the implant, and close follow-up has resulted in good cosmetic outcomes with no implant-related infections.
