RESUMO

BACKGROUND: Basal cisternostomy (BC) is a surgical technique to reduce intracranial hypertension following moderate to severe traumatic brain injury (TBI). As the efficacy and safety of BC in patients with TBI has not been well-studied, we aim to summarize the published evidence on the effect of BC as an adjunct to decompressive hemicraniectomy (DHC) on clinical outcome following moderate to severe TBI. METHODS: A systematic literature review was carried out in PubMed/MEDLINE and EMBASE to identify studies evaluating BC as an adjunct to decompressive hemicraniectomy (DHC) in moderate to severe TBI. Random effects meta-analysis was performed to calculate summary effect estimates. RESULTS: Eight studies reporting on 1345 patients were included in the qualitative analysis, of which five (1206 patients) were considered for meta-analysis. Overall, study quality was low and clinical heterogeneity was high. Adjuvant BC (BC + DHC) compared to standalone DHC was associated with a reduction in the length of stay in the ICU (Mean difference [MD]: -3.25 days, 95% CI: -5.41 to -1.09 days, p = 0.003), significantly lower mean brain outward herniation (MD: -0.68 cm, 95% CI: -0.90 to -0.46 cm, p < 0.001), reduced odds of requiring osmotherapy (OR: 0.09, 95% CI: 0.02 to 0.41, p = 0.002) as well as decreased odds of mortality at discharge (OR 0.68, 95% CI: 0.4 to 0.96, p = 0.03). Adjuvant BC compared to DHC did not result in higher odds of a favourable neurological outcome (OR = 2.50, 95% CI: 0.95-6.55, p = 0.06) and did not affect mortality at final follow-up (OR: 0.80, 95% CI: 0.17 to 3.74, p = 0.77). CONCLUSION: There is insufficient data to demonstrate a potential beneficial effect of adjuvant BC. Despite some evidence for reduced mortality and length of stay, there is no effect on neurological outcome. However, these results need to be interpreted with caution as they carry a high risk of bias due to overall scarcity of published clinical data, technical variations, methodological differences, limited cohort sizes, and a considerable heterogeneity in study design and reported outcomes.

RESUMO

BACKGROUND: The dysmorphogenetic arachnoid cysts' pathomechanism is most favoured, and about 50% occur as middle cranial fossa cysts (MCFAC). Still being rare, management options are yet evolving. We described the clinico-radiological features, management and early outcomes of participants with MCFAC in our service. METHODS: This prospective cohort study involved 29 pediatric participants recruited (from electronic health records, using ICD G93.0 D016080 for arachnoid cysts) between 01/01/2023 and 31/06/2023, following informed consent according to the ethical approval. All participants had neuro-imaging confirmed MCFAC. Baseline and follow-up data were retrieved and analyzed using summary (mean, standard deviation) and inferential (ANOVA, t-test) statistics. RESULTS: They were averagely aged 6.2 ± 4.48 years and were mostly males (89.7%). 24.1% were asymptomatic. The commonest symptoms (n = 38) were headaches (23.7%), developmental delays (15.8%), eye complaints (15.8%) and cephalomegaly (7.9%). They were predominantly left-sided (89.7%). Galassi (G) 3 lesions were less (24.1%), with G2 and G1 lesions evenly sharing the rest. The average cyst volume was 58.4 ± 80.83cm3; there were significant differences (F = 4.682; p = 0.018) between the average volumes for G1 (14.4 ± 22.42cm3), G2 (61.7 ± 89.92cm3) and G3 (122.5 ± 94.37cm3) lesions. 44.8% of the participants had rigid-endoscopic cysto-cisternotomy (all between the ICA and oculomotor nerve into the interpeduncular cistern, using ventriculostomy forceps); including all G3, 50% of G2 and no G1 (had serial clinico-radiological observation) lesion. The average pre- (117.42cm3) and post-operative (53.48cm3) cyst volumes showed significant (t = - 2.797, p = 0.021) reductions. CONCLUSION: Middle cranial fossa arachnoid cysts occur predominantly amongst males, in middle childhood and left-sided. The treatment-related patient series are largely symptomatic, unlike the largely asymptomatic, screening-related series. Higher Galassi grade lesions presented with progressively, significantly larger cyst volumes and higher likelihoods of surgery. The average post-operative cyst volume at follow-up averagely showed almost 60% reduction from the pre-operative. All participants reported clinical remission.

RESUMO

BACKGROUND: Traumatic brain injury (TBI) is a leading cause of morbidity in all age groups worldwide. Decompressive craniectomy (DC) is a salvage procedure in patients with TBI. The outcome and quality of life following DC is questionable. Basal cisternostomy (BC) has been proposed to reduce edema and lead to brain relaxation. It was initially used as an adjunct in TBI patients, thereby improving outcomes. With gaining popularity among neurosurgeons, BC was used as a standalone approach in TBI patients. This network meta-analysis aims to analyze the role of BC either as an adjunct or as a standalone approach in managing TBI patients. METHODS: A comprehensive search of electronic databases (PubMed and SCOPUS) was performed using the search strategy using the field terms and medical subheading terms (MeSH Terms) to retrieve studies describing the role of BC in patients with TBI either as an adjunct with DC or standalone treatment and their outcome. RESULTS: Thirty-one articles were selected for full-text review and 18 articles were selected for the final analysis. BC alone group was found to have minimum in-hospital mortality (odds ratio [OR], 0.348; 95% credible interval [CrI], 0.254 to 0.477) followed by DC combined with BC group (OR, 0.645; 95% CrI, 0.476 to 0.875). DC combined with the BC group was found to have a minimum duration of mechanical ventilation (OR, 0.114; 95% CrI, 0.005 to 2.451) followed by the BC alone group (OR, 0.604; 95% CrI, 0.024 to 15.346). DC combined with the BC group were found to have the maximum Glasgow Outcome Scale score (OR, 1.661; 95% CrI, 0.907 to 3.041) followed by the BC alone group (OR, 1.553; 95% CrI, 0.907 to 3.041). CONCLUSIONS: Our analysis showed that BC alone was associated with lower in-hospital mortality rates in TBI patients. DC with BC had decreased the requirement of mechanical ventilation. However, larger multi-centric studies from other parts of the world are required to confirm these findings.

RESUMO

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.

RESUMO

Intraventricular haemorrhage (IVH) is a severe and acute type of stroke with a complex pathophysiology and is a therapeutic challenge. This case report described a man in his early 50's diagnosed with IVH by computed tomography (CT). Although bilateral extraventricular drainage (EVD) was undertaken, a postoperative CT scan showed that while the left catheter was correctly positioned, the right catheter had been wrongly inserted into the cisterna ambiens. The procedure was equivalent to simultaneous EVD combined with cisternostomy. As a consequence, the haematoma was rapidly removed, the risk of infection and long-term hydrocephalus was reduced, and prognosis was improved. Large case-control studies or prospective studies are needed to evaluate the safety and effectiveness of this treatment modality.

RESUMO

PURPOSE: Intrathecal vasoactive drugs have been proposed in patients with aneurysmal subarachnoid hemorrhage (aSAH) to manage cerebral vasospasm (CV). We analyzed the efficacy of intracisternal nicardipine compared to intraventricular administration to a control group (CG) to determine its impact on delayed cerebral ischemia (DCI) and functional outcomes. Secondary outcomes included the need for intra-arterial angioplasties and the safety profile. METHODS: We performed a retrospective analysis of prospectively collected data of all adult patients admitted for a high modified Fisher grade aSAH between January 2015 and April 2022. All patients with significant radiological CV were included. Three groups of patients were defined based on the CV management: cisternal nicardipine (CN), ventricular nicardipine (VN), and no intrathecal nicardipine (control group). RESULTS: Seventy patients met the inclusion criteria. Eleven patients received intracisternal nicardipine, 18 intraventricular nicardipine, and 41 belonged to the control group. No cases of DCI were observed in the CN group (p = 0.02). Patients with intracisternal nicardipine had a reduced number of intra-arterial angioplasties when compared to the control group (p = 0.03). The safety profile analysis showed no difference in complications across the three groups. Intrathecal (ventricular or cisternal) nicardipine therapy improved functional outcomes at 6 months (p = 0.04) when compared to the control group. CONCLUSION: Administration of intrathecal nicardipine for moderate to severe CV reduces the rate of DCI and improved long-term functional outcomes in patients with high modified Fisher grade aSAH. This study also showed a relative benefit of cisternal over intraventricular nicardipine, thereby reducing the number of angioplasties performed in the post-treatment phase. However, these preliminary results should be confirmed with future prospective studies.

RESUMO

Background: This review is centered on the pivotal role of surgical interventions within the comprehensive management of traumatic brain injury (TBI). Surgical strategies are indispensable components of TBI care, encompassing primary injury management and the alleviation of secondary injury processes, including the handling of intracranial hemorrhages (ICHs), contusions, and mass lesions. Methods: A systematic review was carried out by searching databases including PubMed, Embase, and Scopus. The inclusion criteria involved studies discussing surgical strategies for TBI, with a focus on primary injury management, ICHs, contusions, and mass lesions. More recent articles were prioritized, and data were synthesized to assess the impact of surgical interventions on TBI outcomes. Results: The evolution of surgical technologies has heralded a transformation in TBI management. These advancements encompass minimally invasive procedures, neuroimaging-guided surgeries, and robotic-assisted techniques, all geared toward optimizing patient outcomes. Conclusion: Surgical interventions within TBI care present unique challenges, such as timing considerations, patient selection criteria, and postoperative care. This review underscores the critical significance of multidisciplinary collaboration among neurosurgeons, neurologists, and critical care specialists. Such collaboration is essential to tailor surgical strategies to the individualized needs of patients. Moreover, the review highlights emerging trends in TBI surgery and underscores the ongoing imperative of research endeavors aimed at refining surgical protocols and ultimately enhancing patient outcomes.

RESUMO

Aneurysmal subarachnoid hemorrhage (aSAH) provokes a cascade reaction that is responsible for early and delayed brain injuries mediated by intracranial hypertension, hydrocephalus, cerebral vasospasm (CV), and delayed cerebral ischemia (DCI), which result in increased morbidity and mortality. During open microsurgical repair, cisternal access is achieved essentially to gain proximal vascular control and aneurysm exposition. Cisternostomy also allows brain relaxation, removal of cisternal clots, and restoration of the CSF dynamics through the communication between the anterior and posterior circulation cisterns and the ventricular system, with the opening of the Membrane of Liliequist and lamina terminalis, respectively. Continuous postoperative CSF drainage through a cisternal drain (CD) is a valuable option for treating acute hydrocephalus and intracranial hypertension. Moreover, it efficiently removes the blood and toxic degradation products, with a potential benefit on CV, DCI, and shunt-dependent hydrocephalus. Finally, the CD is an effective pathway to administer vasoactive, fibrinolytic, and anti-oxidant agents and shows promising results in decreasing CV and DCI rates while minimizing systemic effects. We performed a comprehensive review to establish the adjuvant role of cisternostomy and CD performed in cases of direct surgical repair for ruptured intracranial aneurysms and their role in the prevention and treatment of aSAH complications.

RESUMO

Background and Aim: Contemporary management of hydrocephalus involves various modes of cerebrospinal fluid (CSF) diversion, including shunt surgery and endoscopic ventriculostomy. However, there are times when either of these procedures have either failed or are not feasible. Highly invasive procedures aimed at internal CSF have been described previously, which, with the aid of modern microsurgical techniques, can be attempted in cases with very limited options. Our aim was to study the utility of extra-axial third ventriculostomy via lamina terminalis fenestration with multiple cisternostomies in the treatment of failed hydrocephalus. Materials and Methods: Forty-five patients with hydrocephalus were operated for extra-axial trans-lamina terminalis third ventriculostomy with multiple cisternostomies from January 2017 to January 2019. A minimally invasive supraorbital craniotomy was performed with subfrontal fenestration of the lamina terminalis and trans-lamina terminalis fenestration of the floor of the third ventricle with multiple cisternostomies including the optico-carotid cistern and opening of the Liliequist membrane. Results: Tuberculous meningitis was the most common etiology in the series, and multiple shunt procedures and incompatible CSF profiles were the most common reasons that necessitated this alternate rescue procedure. At a mean follow-up of 6 months, no patient required a revision shunt surgery. There was one death due to cardiac failure with anasarca, unrelated to the procedure. Conclusions: Extra-axial trans-lamina terminalis ventriculostomy with cisternostomies can safely be performed using minimally invasive micro-neurosurgical techniques, adding to the armamentarium of neurosurgeons in the management of complex cases of hydrocephalus.

RESUMO

Traumatic brain injury (TBI) can be classified into primary, due to the effect of the initial trauma, or secondary, due to increased intracranial pressure (ICP). Increased ICP may cause brain herniation and also decreases cerebral blood perfusion leading to ischemia. Recently, a few studies showed that cisternostomy with decompressive craniectomy (DC) has better outcomes than DC alone in patients with TBI. This can be explained by the recent advances indicating that cisternal cerebrospinal fluid (CSF) communicates with cerebral interstitial fluid (IF) through Virchow-Robin spaces. Theoretically, opening cisterns to atmospheric pressure may induce IF drainage and subsequently decrease ICP. A 55-year-old man presented to the emergency department with subdural hematomas, hemorrhagic contusions, and subarachnoid hemorrhage after falling off a moving truck. ICP elevation was refractory despite increased sedation, initiation of paralysis with Cisatracurium, esophageal cooling, multiple doses of 23.4 % saline and mannitol, and DC. Lumbar drain (LD) placement was performed with beneficial results. Unfortunately, the LD stopped functioning multiple times and each time this occurred, he developed increased ventricular size with elevated ICP. The patient underwent cisternostomy and lamina terminalis fenestration. No further increased ICPs were observed after cisternostomy at a one-month follow-up. Cisternostomy is a potential surgical treatment for patients with TBI-related prolonged ICP elevation.

RESUMO

Background: Cisternostomy is a surgical technique thought of and developed as an option for severe brain trauma treatment. It demands a particular knowledge and skill to microsurgically approach basal cisterns and effectively manipulate their contents. To perform this procedure safely, the anatomy and pathophysiology must be clearly understood. Methods: Detailed microscopic dissection and anatomical review were done, after a detailed reading of facts and recent publications about cisternostomy. Cisternal pathways and landmark planning are described and augmented using a new method to show de arachnoid borders. Finally, a brief discussion is written as a synopsis. Results: Cisternostomy requires thorough microscopic knowledge and microsurgical skills. This paper intends to provide information to understand better the anatomy related, thus, easing the learning curve. The technique used to show arachnoid borders, complementing cadaveric and surgical images, was useful for this purpose. Conclusion: To perform this procedure safely, it is mandatory to handle microscopic details of cistern anatomy. Reaching a core cistern is necessary to assure effectiveness. This procedure needs, as well, surgical step-by-step landmark planning and performing. Cisternostomy could be a life-saving procedure and a new powerful tool for severe brain trauma treatment. Evidence is being collected to support its indications.

RESUMO

BACKGROUND: Hydrocephalus is one of the major complications of aneurysmal subarachnoid haemorrhage (aSAH). In the acute setting, an external ventricular drain (EVD) is used for early management. A cisternal drain (CD) coupled with the micro-surgical opening of basal cisterns can be an alternative when the aneurysm is clipped. Chronic hydrocephalus after aSAH is managed with ventriculo-peritoneal (VP) shunt, a procedure associated with a wide range of complications. The aim of this study is to analyse the impact of micro-surgical opening of basal cisterns coupled with CD on the incidence of VP shunt, compared to patients treated with EVD. METHODS: The authors conducted a retrospective review of 89 consecutive cases of patients with aSAH treated surgically and endovascularly with either EVD or CD between January 2009 and September 2021. Patients were stratified into two groups: Group 1 included patients with EVD, Group 2 included patients with CD. Subgroup analysis with only patients treated surgically was also performed. We compared their baseline characteristics, clinical outcomes and shunting rates. RESULTS: There were no statistically significant differences between the two groups in terms of epidemiological characteristics, WFNS score, Fisher scale, presence of intraventricular hemorrhage (IVH), acute hydrocephalus, postoperative meningitis or of clinical outcomes at last follow-up. Cisternostomy with CD (Group 2) was associated with a statistically significant reduction in VP-shunt compared with the use of an EVD (Group 1) (9.09% vs 53.78%; p < 0.001). This finding was confirmed in our subgroup analysis, as among patients with a surgical clipping, the rate of VP shunt was 43.7% for the EVD group and 9.5% for the CD group (p = 0.02). CONCLUSIONS: Cisternostomy with CD may reduce the rate of shunt-dependent hydrocephalus. Cisternostomy allows the removal of subarachnoid blood, thereby reducing arachnoid inflammation and fibrosis. CD may enhance this effect, thus resulting in lower rates of chronic hydrocephalus.

RESUMO

Background: Basal cisternostomy (BC) recently emerged as an adjuvant/alternative procedure to decompressive craniectomy (DC) in traumatic brain injuries (TBIs) with its potential to effectively reduce both intracranial pressure (ICP) and brain edema. However, its role in TBI is not yet established in the true sense and with clarity. The objective of the present study was to evaluate the effect of adjuvant BC on ICP, mortality, and clinicoradiological outcome. Methods: A single-center randomized control trial was conducted. Fifty patients were assigned to each DC-group and DC+BC-group. Randomization was done using the sealed envelope method. Both groups were followed in the postoperative period to compare the impact of surgery on ICP, radiological changes, and clinical outcome (mortality, days on ventilator/in intensive care unit (ICU), and Glasgow outcome scale-extended (GOS-E) at 12 weeks). Results: Both groups were comparable in terms of preoperative clinicoradiological characteristics. On postoperative days 1, 2, and 3, mean ICP was significantly low in the DC+BC-group (P < 0.0001). The decline in ICP in the DC+BC-group was significant in both moderate and severe TBI patients. In comparison, DC+BC-group has a shorter duration of mechanical ventilation/ICU stay and significantly better GOS-E score at 12 weeks (P < 0.0001*). The mortality rate was less in the DC+BC-group (48%) as compared to the DC-group (64%). Among radiological features, mean midline shift and mean outward brain herniation were significantly less in the DC+BC group. Bone-flap replacement was possible in ten patients of DC+BC-group at the time of primary surgery. Conclusion: Results of our study indicated that BC is beneficial in reducing both ICP and brain edema, which translates into favorable clinicoradiological outcomes.

RESUMO

Subarachnoid basal cistern opening (cisternotomy) is used during many microsurgical operations to relax the brain by removing or diverting cerebrospinal fluid (CSF). Recently, cisternotomy has been used in patients with traumatic brain injury to improve outcomes due to its ability to decrease intracranial pressure (ICP) and brain edema by diverting CSF. Theoretically, another condition that can benefit from cisternotomy is idiopathic intracranial hypertension (IIH) as it presents with manifestations of increased ICP, such as headache, vomiting, and papilledema. Here, we discuss the case of a 39-year-old woman with IIH who presented with headache, nausea, and papilledema in the setting of maximally tolerated medical management after five months of shunt removal due to infection. The patient did not want to proceed with the replacement of her shunt and therefore underwent a right eyebrow craniotomy for cisternotomy, lamina terminals fenestration, and Liliequist's membrane opening. Postoperatively, her symptoms improved completely. She was off acetazolamide altogether at the three-month follow-up and no longer had pseudotumor cerebri headaches. This case report demonstrates the use of cisternotomy to relieve the manifestations of increased ICP and its potential as a surgical option for patients with IIH.

RESUMO

Background: Cisternostomy has recently been reintroduced in the setting of severe TBI as an adjuvant surgical technique for decreasing brain edema and refractory intracranial hypertension. However, there is not much clarity regarding its role in head injury. Objective: Study the effect of cisternostomy on intracranial pressure, morbidity, and mortality in head-injured patients. Material and Methods: We conducted a single-center quasi-experimental study between November 2018 and November 2020. All candidates for decompressive hemicraniectomy (DHC) were divided into two groups: DHC-BC (undergoing basal cisternostomy with DHC) and DHC (undergoing DHC alone). We compared the impact of surgery on decreasing ICP and clinical outcomes in both groups. Results: During the study duration, we admitted 659 head-injury patients. Forty patients were included in the study (9 in the DHC-BC group and 31 in the DHC group). Both the groups were comparable in terms of baseline clinical characteristics such as age, gender, preoperative GCS, head injury severity, radiological features, and opening ICP. Patients in both groups had a decline in ICP following surgery. The mean closing pressure in the DHC-BC group (11.3 ± 5.9) was significantly higher than that in the DHC group (5.3 ± 3.5) (P = 0.003). The mean drop in ICP in the DHC-BC group was 14.4 ± 11.5 while that in the DHC group was 18.9 ± 12.4 (P = 0.359). The average total number of hours of ICP >20 mm Hg and intracranial hypertension index were higher for the DHC-BC group. The average number of days of stay in the ICU and hospital were lower for the DHC-BC group (7.0 ± 6.1 and 15.0 ± 20.2, respectively) compared to the DHC group (10.6 ± 9.3 and 19.3 ± 13.9, respectively). The 30-day mortality rate was higher for the DHC-BC group (66.6%) than the DHC group (32.2%). The mean GCS at discharge was better in the DHC-BC group (11.7 ± 2.9) compared to 10.5 ± 3.7 in the DHC group, while 11.1% of patients in the DHC-BC group had a favorable outcome (1-month GOS-E) compared to 9.7% patients in the DHC group. Conclusions: Our preliminary single-center study failed to show a clear benefit of adding basal cisternostomy to decompressive hemicraniectomy in patients with head injuries.

RESUMO

Introduction: Cisternostomy is emerging as a novel surgical technique in the setting of severe brain trauma. Different surgical techniques have been proposed with a variable degree of epidural bone work. We present here the surgical technique as it is currently performed in our Institution. Methods: Anatomical dissection of one adult cadaveric head, injected and non-formalin fixed was perfomed. A large right fronto-temporo-parietal craniotomy was accomplished. Extradural sphenoidal drilling till opening of the superior orbital fissure was performed. The microsurgical anatomy of basal cisternostomy was then explored. Results: A step by step description of the surgical technique, enriched with cadaveric and intraoperative images, was made. Conclusion: Basal cisternostomy is a promising surgical technique that does not necessarily include complex surgical maneuvers. Trained neurosurgeon can safely implement it in their clinical practice.

RESUMO

BACKGROUND: The goal of treatment of traumatic brain injury (TBI) is to avoid secondary brain injury. Decompressive craniectomy has been shown to reduce intracranial pressure (ICP), but it actually provides an outlet for brain tissue to expand without reducing edema. Basal cisternostomy is an emerging microsurgical technique to manage cerebral edema in TBI. Cerebrospinal fluid is released from basal cisterns, which reduces cerebral edema. We compared outcomes of cisternostomy with decompressive craniectomy in a randomized controlled trial and studied the effectiveness of cisternostomy in decreasing cerebral edema. METHODS: All enrolled patients were randomly assigned to 2 groups and assessed clinically and radiologically. TBIs were categorized as mild, moderate, and severe injuries, and Marshall computed tomography-based score was assessed. Intraoperative ICP was measured in both groups. Outcomes were assessed based on postoperative intensive care unit stay, days on ventilator support, and Glasgow Outcome Scale score. RESULTS: There were 50 patients randomly assigned to 2 groups (25 patients in each group). Mortality rate was 32% (8 deaths) in the cisternostomy group and 44% (11 deaths) in the decompressive craniectomy group. Patients in the cisternostomy group had decreased mean days of ventilator support and intensive care unit stay. Cisternostomy resulted in significant decreases in ICP after craniotomy. Age, time from trauma to surgery, and Marshall score showed prognostic importance on outcomes. CONCLUSIONS: Cisternostomy was effective in reducing ICP in patients with TBI. Good Glasgow Outcome Scale scores and low rates of complications were found in the postoperative period after cisternostomy. Age, presenting Glasgow Coma Scale score, Marshall score, other major injuries, and time from trauma to surgery had a significant prognostic impact on outcome in management of TBI.

RESUMO

In subarachnoid hemorrhage following traumatic brain injury (TBI), the high intracisternal pressure drives the cerebrospinal fluid into the brain parenchyma, causing cerebral edema. Basal cisternostomy involves opening the basal cisterns to atmospheric pressure and draining cerebrospinal fluid in an attempt to reverse the edema. We describe a case of basal cisternostomy combined with decompressive craniectomy. A 35-year-old man with severe TBI following a road vehicle accident presented with acute subdural hematoma, Glasgow coma scale score of 6, fixed pupils and no corneal response. Opening of the basal cisterns and placement of a temporary cisternal drain led to immediate relaxation of the brain. The patient had a Glasgow coma scale score of 15 on postoperative day 6 and was discharged on day 10. We think basal cisternostomy is a feasible and effective procedure that should be considered in the management of TBI.
