RESUMO
OBJECTIVE: To date, there is no consensus on the surgery strategies of cranioplasty (CP) and ventriculoperitoneal shunt (VPS) placement. This meta-analysis aimed to investigate the safety of staged and simultaneous operation in patients with comorbid cranial defects with hydrocephalus to inform future surgery protocols. METHODS: A meta-analysis of PubMed, Ovid, Web of Science, and Cochrane Library databases from the inception dates to February 8, 2023 adherent to PRISMA guidelines was conducted. The pooled analyses were conducted using RevMan 5.3 software. The outcomes included postoperative infection, reoperation, shunt obstruction, hematoma, and subdural effusion. RESULTS: Of the 956 studies initially retrieved, 10 articles encompassing 515 patients were included. Among the total patients, 193 (37.48%) and 322 (62.52%), respectively, underwent simultaneous and staged surgeries. The finding of pooled analysis indicated that staged surgery was associated with lower rate of subdural effusion (14% in the simultaneous groups vs. 5.4% in the staged groups; OR = 2.39, 95% CI: 1.04-5.49, p = 0.04). However, there were no significant differences in overall infection (OR = 1.92, 95% CI: 0.74-4.97, p = 0.18), central nervous system infection (OR = 1.50, 95% CI: 0.68-3.31, p = 0.31), cranioplasty infection (OR = 1.58, 95% CI: 0.50-5.00, p = 0.44), shunt infection (OR = 1.30, 95% CI: 0.38-4.52, p = 0.67), reoperation (OR = 1.51, 95% CI: 0.38-6.00, p = 0.55), shunt obstruction (OR = 0.73, 95% CI: 0.25-2.16, p = 0.57), epidural hematoma (OR = 2.20, 95% CI: 0.62-7.86, p = 0.22), subdural hematoma (OR = 1.20, 95% CI: 0.10-14.19, p = 0.88), and intracranial hematoma (OR = 1.31, 95% CI: 0.42-4.07, p = 0.64). Moreover, subgroup analysis failed to yield new insights. CONCLUSIONS: Staged surgery is associated with a lower rate of postoperative subdural effusion. However, from the evidence of sensitivity analysis, this result is not stable. Therefore, our conclusion should be viewed with caution, and neurosurgeons in practice should make individualized decisions based on each patient's condition and cerebrospinal fluid tap test.

BACKGROUND: Campylobacter jejuni is a common cause of acute gastroenteritis, but central nervous system infections are rare manifestations of Campylobacter infection. Therefore, C. jejuni trauma-related subdural hygroma infection in children is poorly described in the literature. CASE PRESENTATION: We described a 2-year old boy with lobar holoprosencephaly presenting with subdural hygroma following head trauma. C. jejuni infection was confirmed from a subdural hygroma sample by culture as well as by DNA sequencing of a broad range 16S rDNA PCR product. Cerebrospinal fluid from the ventriculoperitoneal shunt remained sterile. Combined neurosurgical and antimicrobial treatment led to complete recovery. Review of the literature showed that the most common manifestation of Campylobacter central nervous system infection is meningitis, mostly in neonates, and subdural hygroma infection was described for only one case. CONCLUSIONS: Subdural hygroma infection caused by C. jejuni is a rare clinical condition in children. Molecular methods represent an important tool for the detection of rare or unexpected pathogens. No standard recommendations for antimicrobial treatment of C. jejuni subdural space infection in children are available, but meropenem treatment combined with surgery seems to be an effective approach.

Se describe el caso clínico de un lactante de 47 días de nacido, quien fue atendido en el Cuerpo de Guardia de Pediatría del Hospital Provincial General Docente Antonio Luaces Iraola de Ciego de Ávila, por presentar aumento de la circunferencia cefálica, irritabilidad y agitación. Los exámenes realizados mostraron signos de hipertensión endocraneana descompensada, secundaria a colección del espacio subdural izquierdo. Se eliminó el higroma subdural y la recuperación fue favorable en las primeras 36 horas; luego comenzó a convulsionar y apareció nuevamente el deterioro neurológico, por lo cual se decidió reintervenir. Se realizó inducción anestésica con tiopental sódico fentanilo y rocuronio. El paciente evolucionó sin complicaciones.
The case report of a 47 days infant is described. He was assisted in the children emergency room of Antonio Luaces Iraola Teaching General Provincial Hospital in Ciego de Ávila, due to an increase of the cephalic circumference, irritability and agitation. The exams showed signs of upset endocranial hypertension, secondary to collection of the left subdural space. The subdural hygroma was eliminated and the recovery was favorable in the first 36 hours; then a covulsion began and the neurological deterioration appeared again, reason why it was decided to operate once more. Anesthetic induction was carried out with fentanyl sodium thiopental and rocuronium. The patient had a favorable clinical course without complications.

OBJECTIVE: Contralateral subdural effusion after decompressive craniectomy (CSEDC) is rare, and the optimal treatment is not determined. We present 11 cases of CSEDC and give an overview of the English literature pertaining to this disease. METHODS: We searched the database at our institution and performed a search of English literature in PubMed and Google Scholar. Keywords used were as follows (single word or combination): "subdural hygroma"; "subdural effusion"; "decompressive craniectomy". Only patients with CSEDC and contained adequate clinical information pertinent to the analysis were included. RESULTS: 11 cases of CSEDC were recorded at our institution. They comprised ten men and one woman with an average age of 41.9 years. All the 8 symptomatic patients underwent surgery and the CSEDC resolved gradually. 68 cases of CSEDC were found in the literature. Including ours, a total of 79 patients were analyzed. Conservative treatment was effective in the asymptomatic patients. 41.7% of the symptomatic CSEDC underwent burr hole drainage and successfully drained the CSEDC. However, 76% of them received subsequent surgery to manage the reaccumulation of CSEDC. 25% of the symptomatic patients underwent cranioplasty, while 13.3% of them received Ommaya drainage later because of CSEDC recurrence. 18.3% of the symptomatic patients underwent cranioplasty plus subduroperitoneal shunting, and all CSEDC resolved completely. CONCLUSIONS: Burr hole drainage appears to be only a temporary measure. Early cranioplasty should be performed for patients with CSEDC. CSF shunting procedures may be required for patients in whom CSEDC have not been solved or hydrocephalus manifest after cranioplasty.

OBJECTIVES: This study aimed to summarize the surgical strategies for subdural effusion secondary to decompressive craniectomy (SESDC) and discuss the applicable scenarios of effusion-peritoneal shunt (EP shunt). METHODS: A total of 53 consecutive patients with SESDC were screened out of 7569 cases. The SESDC was divided into five types, and the treatment methods of each type were analyzed and compared. According to the implementation strategy of cranioplasty (CP), patients were divided into CP-first and delayed-CP groups. The differences in surgical methods were compared between the two groups. RESULTS: All patients with SESDC in this cohort had undergone cranioplasty. Subcutaneous puncture and aspiration (SPAA) proved ineffective. Only 2/30 patients in the CP-first group used EP shunt, while 6/19 patients in the delayed-CP group used EP shunt; the difference was statistically significant (P = 0.03). A significant difference was found in the use of EP shunt among type 1, type 2, and type 5 SESDC (χ2 = 6.778, P = 0.034). CONCLUSIONS: CP combined with other treatments could cure most SESDC. EP shunt should be used preferentially in some specific scenarios in which CP cannot be performed first, rather than as a backup measure that can only be used when other preceding treatments fail.

PURPOSE: Surgical fenestration is widely accepted as a primary treatment for middle fossa arachnoid cysts (MFACs) in pediatric patients. However, postoperative subdural effusion and/or hydrocephalus always affect treatment outcomes. In this study, we presented our experience of treating MFACs with surgical fenestration in pediatric patients and analyzed the cases complicated by postoperative subdural effusion and/or hydrocephalus, to give insight into the clinical characteristics predisposing the complications. METHODS: We retrospectively analyzed 21 pediatric cases with MFACs treated by surgical fenestration suffering postoperative subdural effusion and/or hydrocephalus in our department from November 2011 to April 2019. We reviewed the clinical characteristics and treatment outcomes. RESULTS: A total of 21 patients, among a total of 53 pediatric patients with MFACs treated by surgical fenestration, developed subdural effusion and/or hydrocephalus postoperatively. The mean age at the time of the initial surgery was 49 months. A total of 75% (6/8) of the patients under 2 years old and 13.3% (6/45) of the older patient group sustaining postoperative subdural effusion and/or hydrocephalus required further surgeries, respectively (Fisher's exact test, p = 0.001). Notably, among the 21 cases with postoperative subdural effusion and/or hydrocephalus, all the 6 patients under 2 years old needed additional surgeries, while of the other 15 older patients, only 40% (6/15) needed further surgical interventions (Fisher's exact test, p = 0.019). CONCLUSION: The immature CSF absorption in MFAC patients younger than 2 years old might predispose them to the relatively serious postoperative subdural effusion and/or hydrocephalus. For very young patients with giant MFACs, surgical fenestration might not be the best option.

INTRODUCTION: Decompressive craniectomy is an important method for managing refractory intracranial hypertension. Although decompressive craniectomy is a relatively simple procedure, various complications may arise. The aim of our paper was to determine the incidence of complications of decompressive craniectomy in patients with head injury and to analyse their risk factors. METHODS: We retrospectively analysed a group of 94 patients after decompressive craniectomy for head injury between 01 Jan 2014 and 31 Dec 2018. Postoperative complications were evaluated based on clinical examination and postoperative CT scan. The impact of potential risk factors on the occurrence of complications was assessed (age, worse initial clinical condition, any haemocoagulation disorder). RESULTS: Twenty patients died within the first month after surgery. Control CT scan showed one complication in 78 patients (83%), while 46 patients (49%) had more than one complication. We had to reoperate 22 patients (23.4%) due to a complication. The following complications were found: postoperative acute subgaleal/subdural haematoma (30× - 32%), subgaleal/subdural cerebrospinal fluid effusion (29× - 31%), soft tissues oedema (29× - 31%), haemorrhagic progression of brain contusion (17× - 18%), malignant brain oedema (8× - 8.5%), hydrocephalus (8× - 8.5%), temporal muscle atrophy (7× - 7.5%), peroperative massive bleeding ( 6× - 6.4%), epilepsy (4× - 4.3%), syndrome of the trephined (2× - 2.1%), skin necrosis (2× - 2.1%). Patients with a haemocoagulation disorder had a significantly higher incidence of complications (p=0.01). CONCLUSION: Complications of decompressive craniectomy after head injury are frequent. The potential benefit of decompressive craniectomy can be adversely affected by the occurrence of many complications.

OBJECTIVE: This article discusses the procedure of foramina magnum and Magendie dredging, summarizing the pathologic changes in the intradural region of the craniocervical junction in patients with syringomyelia and the pathophysiologic mechanism of cerebrospinal fluid (CSF) circulation obstruction. METHODS: Clinical data from 50 adult patients with syringomyelia treated at Xuanwu Hospital from July 2018 to January 2019 were collected and retrospectively analyzed. All operations were performed with foramina magnum and Magendie dredging, and all intradural factors that may have induced the obstruction of CSF circulation were recorded. RESULTS: Intradural pathology was found in all patients. The pathologic changes that may have caused obstruction of the CSF circulation include tonsil occupying the foramen magnum and overlying foramen of Magendie in 88% (44/50), intertonsillar arachnoid adhesions in 36% (18/50), tonsil to medulla arachnoid adhesions in 18% (9/50), medialized tonsils in 70% (35/50), vermian branch of posterior inferior cerebellar artery in 22% (11/50), arachnoid veil in 16% (8/50), cisterna magna cyst in 4% (2/50), and tonsil to dura mater arachnoid adhesions in 8% (4/50). Mean duration of follow-up was 13.3 months. The long-term effective rate was 96.0%. Postoperative magnetic resonance imaging revealed that the size of the syringomyelia was reduced or completely resolved in 88% of patients. The mean preoperative Japanese Orthopaedic Association score was 12.9 ± 3.1, which improved to 14.7 ± 3.2 (P < 0.05) at last clinical follow-up. CONCLUSIONS: Intradural pathology that causes CSF circulation obstruction exists in many forms. Relieving the obstruction of the foramen magnum and foramen of Magendie is key to surgical treatment.

PURPOSE: Rupture of arachnoid cysts (AC) in the subdural space after trauma may cause a subacute/chronic subdural hematoma or a hygroma. Treatment of this complication still remains controversial, and no consensual strategy is to date clearly proposed. In this study, the authors evaluated the clinical and radiological evolution of patients treated by a subduro-peritoneal shunt for symptomatic subdural collections complicating ruptured AC. METHODS: Medical records of the 10 patients treated at our institution between January 2005 and December 2018 for a subdural collection associated with an intracranial AC were reviewed. Subduro-peritoneal shunts consisted of low-pressure valves from 2005 to 2012 (6 cases) and medium-pressure valves after 2012 (4 cases). RESULTS: A benign head trauma was retrospectively found in the history of 8 patients. The mean time to diagnosis ranged from 15 days to 5 months. Symptoms resulted mainly from intracranial hypertension. Six patients had an ipsilateral hygroma to the AC, 2 patients had a bilateral hygroma predominantly to the AC side, and 2 patients presented an ipsilateral chronic subdural hematoma. Arachnoid cysts were classified as Galassi I in 5 cases and Galassi II in 5 cases. Patients with chronic subdural hematoma were given a medium-pressure valve. Patients with subdural hygroma received a low-pressure valve in 6 cases and a medium-pressure valve in 2 cases. There were no complications during surgical procedures. All patients were rapidly free of symptoms after surgery and were discharged from hospital 1 to 4 days postoperatively. The subdural collection completely disappeared in all cases. In the long term, only 2 patients with low-pressure valves underwent shunt removal without any consequences, while a second surgical procedure was necessary to treat recurrence of intracranial hypertension in the 4 remaining cases. All the medium-pressure valves were removed without problems. The size of the AC was reduced in 3 cases, remained stable in 4 cases, and increased in 3 cases. No patients experienced recurrence of subdural collection during follow-up. CONCLUSIONS: Medium-pressure subduro-peritoneal shunts should be considered as part of the arsenal of surgical strategy in symptomatic ruptured AC in the subdural space. The procedure is simple with a very low morbidity, and it allows rapid improvement of symptoms. Although the shunt is located in the subdural space, we strongly recommend avoiding devices which may create an overdrainage and expose the patient to shunt dependency such as low-pressure shunts.

BACKGROUND: Intramedullary spinal cord dermoid tumors are rare. Early diagnosis with appropriate imaging is of utmost importance for a good outcome. Gross total resection is the treatment of choice for optimal results. Neurosurgical intervention for any intramedullary lesion is fraught with problems because of the nature of the lesion and handling of the spinal cord, which is already compromised because of the intramedullary lesion. Recurrence of the intramedullary dermoid tumor is frequent because of incomplete resection of the tumor. Most commonly, patients present with worsening of neurologic deficits. Inadequate resection because of the fear of worsening the neurologic deficits is associated with significant complications. CASE DESCRIPTION: We report a case of an intramedullary dermoid tumor in a child that was associated with myriad of complications owing to incomplete resection of the tumor. The patient underwent multiple interventions at various centers which resulted in serious multiple complications before presenting at our center for further management. CONCLUSIONS: This report highlights the spectrum of complications that can develop in a patient varying from worsening of the deficits to meningitis and subsequent development of hydrocephalus.

RATIONALE: Atlantoaxial transarticular screw fixation has been an effective and appealing method for inducing fusion of the C1-C2 complex. This technique is usually performed with Gallie fusion. In performing Gallie fusion using sublaminar wiring, a major concern is the risk of dural tear associated with passing sublaminar wires through the epidural space. We present the first report on symptomatic symptomatic subdural hygroma (SDH) due to transarticular screw fixation with posterior wiring. PATIENTS CONCERNS: A 50-year-old man had sustained dens fracture 20 years ago and presented with severe neck pain following a recent traffic accident. The images showed atlantoaxial instability due to nonunion of the dens fracture and the patient underwent transarticular screw fixation with posterior sublaminar wiring using Gallie technique. When the U-shaped wire was passed under the arch of C1 from inferior to superior, a dural tear and cerebrospinal fluid (CSF) leak occurred. The site of dural tear was repaired by direct application of sutures. The patient was discharged in good condition. Fifteen day after surgery, the patient was readmitted with a history of a progressive headache associated with vomiting and vertigo. DIAGNONSIS: Brain CT and MRI showed bilateral posterior fossa and a right-sided supratentorial SDH. INTERVENTIONS: The patient underwent right occipital burr hole and evacuation of posterior fossa SDH due to deteriorating neurological status. OUTCOMES: The patient's condition gradually improved after the operation and became asymptomatic at 3-year follow-up. LESSONS: Posterior fossa and supratentorial SDH could occur resulting from any intraoperative dural tear and CSF leakage during posterior cervical spinal surgery. Symptomatic SDH after posterior cervical spinal surgery should be cautiously assessed and treated. LEVEL OF EVIDENCE: 5.

BACKGROUND: Subdural effusion with hydrocephalus (SDEH) is a rare complication of traumatic brain injury, especially following decompressive craniectomy (DC) for posttraumatic cerebral infarction. The diagnosis and treatment are still difficult and controversial for neurosurgeons. CASE PRESENTATION: A 45-year-old man developed traumatic cerebral infarction after traumatic brain injury and underwent DC because of the mass effect of cerebral infarction. Unfortunately, the complications of traumatic subdural effusion (SDE) and hydrocephalus occurred in succession following DC. Burr-hole drainage and subdural peritoneal shunt were performed in sequence because of the mass effect of SDE, which only temporarily improved the symptoms of the patient. Cranioplasty and ventriculoperitoneal shunt were performed ultimately, after which SDE disappeared completely. However, the patient remains severely disabled, with a Glasgow Outcome Scale of 3. CONCLUSIONS: It is important for neurosurgeons to consider the presence of accompanying hydrocephalus when treating patients with SDE. Once the diagnosis of SDEH is established and the SDE has no mass effect, timely ventriculoperitoneal shunt may be needed to avoid multiple surgical procedures, which is a safe and effective surgical method to treat SDEH.

OBJECTIVE: Various surgical techniques have been described to treat subdural fluid collections in infants, including transfontanelle aspiration, burr holes, subdural drain, subduroperitoneal shunt, and minicraniotomy. The purpose of this study was to describe a modification of the minicraniotomy technique that avoids the implantation of external drainage catheters and potentially carries a higher success rate. METHODS: In this retrospective study, the authors describe 11 cases involving pediatric patients who underwent parietal minicraniotomies for the evacuation of subdural fluid collections. In contrast to cases previously described in the literature, no patient received a drain; instead, a subgaleal pocket was created such that the fluid could flow from the subdural to the subgaleal space. Preoperative and postoperative data were reviewed, including neurological examination findings, radiological findings, complications, hospital length of stay, and findings on follow-up examinations and imaging. The primary outcome was failure of the treatment strategy, defined as an increase in subdural fluid collection requiring further intervention. RESULTS: Eleven patients (8 boys and 3 girls, median age 4.5 months) underwent the described procedure. Eight of the patients had complete resolution of the subdural collection on follow-up imaging, and 2 had improvement. One patient had a new subdural collection due to a second injury. Only 1 patient underwent aspiration and subsequent surgical repair of a pseudomeningocele after the initial surgery. Notably, no patients required subduroperitoneal shunt placement. CONCLUSIONS: The authors describe a new surgical option for subdural fluid collections in infants that allows for more aggressive evacuation of the subdural fluid and eliminates the need for a drain or shunt placement. Further work with more patients and direct comparison to other alternative therapies is necessary to fully evaluate the efficacy and safety of this new technique.

The appearance of a subdural hygroma after the rupture of an arachnoid cyst wall is extremely rare, with very few cases described in the literature. Most cases are due to a traumatic cause. The therapeutic approach in symptomatic cases is controversial, with a current tendency toward conservative management initially. In those cases that require surgical treatment, multiple therapeutic options are available, with fenestration techniques being recommended as first-line treatment. We describe 2cases treated in our centre and review the literature.

BACKGROUND: Subdural hygroma is a rare disease most commonly encountered in posttraumatic patients. Even more rarely, it has been described as a complication of cerebellopontine angle tumor requiring surgical evacuation. CASE DESCRIPTION: This report discusses 2 patients who underwent surgery for cerebellopontine angle tumor and who both developed symptomatic subdural hygromas a few days later. Both became highly symptomatic but symptoms resolved spontaneously and promptly before planned surgery. CONCLUSIONS: These 2 cases highlight the 2 principal pathogenesis theories for the development of subdural hygromas (arachnoid tear and effusion) and suggest a theory for their sudden and spontaneous resolution: the pressure equilibrium opening the valve created by the arachnoid tear. Eventhough surgical treatment remains the recommended attitude, these cases show that conservative treatment can be an option in some cases.

BACKGROUND: Chiari malformation type I is a hindbrain abnormality characterized by descent of the cerebellar tonsils beneath the foramen magnum, frequently associated with symptoms or brainstem compression, impaired cerebrospinal fluid circulation, and syringomyelia. Foramen magnum decompression represents the most common way of treatment. Rarely, subdural fluid collection and hydrocephalus represent postoperative adverse events. The treatment of this complication is still debated, and physicians are sometimes uncertain when to perform diversion surgery and when to perform more conservative management. CASE DESCRIPTION: We report an unusual occurrence of subdural fluid collection and hydrocephalus that developed in a 23-year-old patient after foramen magnum decompression for Chiari malformation type I. Following a management protocol, based on a step-by-step approach, from conservative therapy to diversion surgery, the patient was managed with urgent external ventricular drainage, and then with conservative management and wound revision. CONCLUSIONS: Because of the rarity of this adverse event, previous case reports differ about the form of treatment. In future cases, finding clinical and radiologic features to identify risk factors that are useful in predicting if the patient will benefit from conservative management or will need to undergo diversion surgery is only possible if a uniform form of treatment is used. Therefore, we believe that a management algorithm based on a step-by-step approach will reduce the use of invasive therapies and help to create a standard of care.

BACKGROUND: Posttraumatic posterior fossa epidural hygroma is a rare entity, and a clear management has not been established in the medical literature. We present 1 case and review the literature relevant to this unusual entity. The mechanism of formation and management of posterior cranial fossa epidural hygroma are also outlined. CASE DESCRIPTION: A 2-year-old child presented after a rooftop fall injury with symptoms of headache, drowsiness, vomiting, and brief loss of consciousness. Computed tomography scan demonstrated swelling in the left occipital region and epidural hygroma. After conservative management failed, surgical repair of the dura mater was performed. The child was discharged postoperative day 11 in stable condition with marked improvement in occipital swelling. CONCLUSIONS: It is imperative to consider epidural hygroma in very small children presenting with occipital injury. As a result of loose adhesion of dura mater and internal cranial lamina layers in younger pediatric patients, potential epidural space may be easily created secondary to injury, and small breaches in meningeal integrity near the cisterna magna may favor cerebrospinal fluid leak. During surgery, if watertight repair of a visible dural tear is performed, duro-periosteal hitching or vacuum drain placement may not be required.

OBJECTIVE: Spontaneous spinal CSF leaks are an important cause of new-onset headaches. Such leaks are reported to be particularly common at the cervico-thoracic junction. The authors undertook a study to determine the significance of these cervico-thoracic CSF leaks. METHODS: The patient population consisted of a consecutive group of 13 patients who underwent surgery for CSF leak repair based on CT myelography showing CSF extravasation at the cervico-thoracic junction but without any evidence of an underlying structural lesion. RESULTS: The mean age of the 9 women and 4 men was 41.2 years. Extensive extrathecal longitudinal CSF collections were demonstrated in 11 patients. At surgery, small leaking arachnoid cysts were found in 2 patients. In the remaining 11 patients, no clear source of CSF leakage could be identified at surgery. Resolution of symptoms was achieved in both patients with leaking arachnoid cysts, but in only 3 of the 11 patients with negative intraoperative findings. Postoperative spinal imaging was performed in 9 of the 11 patients with negative intraoperative findings and showed persistence of the longitudinal intraspinal extradural CSF. Further imaging revealed the site of the CSF leak to be ventral to the thoracic spinal cord. Five of these patients underwent microsurgical repair of the ventral CSF leak with resolution of symptoms in all 5 patients. CONCLUSIONS: Cervico-thoracic extravasation of dye on myelography does not necessarily indicate the site of the CSF leak. Treatment directed at this site should not be expected to have a high probability of sustained improvement of symptoms.

OBJECTIVE: Patients with chronic subdural haematoma and contralateral subdural effusion are rare after head injury. Surgery might reduce clinical progression of subdural effusion, but is not used routinely. This study aimed to investigate the effect of surgery on subdural effusion and clinical outcome. METHODS: A retrospective study was performed, comparing operation and non-operation in the patients with chronic subdural haematoma and contralateral subdural effusion, in a series of 47 patients divided into two groups. The operation group of 21 patients underwent bilateral surgery. The non-operation group of 26 patients underwent surgery on the side with chronic subdural haematoma. Neurological status was assessed by the Glasgow Coma score and Modified Rankin Scale score on admission and at follow-up. All cases underwent pre- and post-operative computed tomography scans. RESULTS: Pre-operative clinical and radiological data were similar in the two groups. The rate of subdural effusion progression was significantly lower in the operation group than in the non-operation group (p < 0.05). Thirteen cases (50%) in the non-operation group and three cases (14.3%) in the operation group had progression of subdural effusion to chronic subdural haematoma (p < 0.05). Chronic subdural haematoma recurrence rate, mortality and neurological recovery were similar, with no significant difference between groups. CONCLUSIONS: The patients benefitted from surgery for subdural effusion when they had chronic subdural haematoma and contralateral subdural effusion.
