Clinical analysis of hyperbaric oxygen combined with subdural drilling and drainage in the management of subdural effusion type IV with intracranial infection in infant patients

Background

To explore the therapeutic effect of hyperbaric oxygen combined with subdural drilling and drainage (SDD) on subdural effusion type IV with intracranial infection in infant patients.

Methods

This retrospective controlled study included 328 infant patients with subdural effusion type 4 with intracranial infection between January 2005 and January 2023. 178 patients were treated by hyperbaric oxygen combined with SDD (group A). 142 cases were treated with SDD (group B). 97 infants were only received hyperbaric oxygen (group C). Clinical outcomes, the control time of intracranial infection, complications, and the degree of brain re-expansion after 6 months of treatment were compared among the three groups. According to the comprehensive evaluation of treatment effectiveness and imaging results, it is divided into four levels: cured, significantly effective, improved, and ineffective.

Results

No patient died during follow-up. The three groups were similar regarding age, sex, the general information, and clinical symptoms (p > 0.05). All intracranial infections in the children were effectively controlled. There was no difference in infection control time between group A and group B, and there was no statistical significance. However, the control time of intracranial infection between the two groups was different from that of group C, which was statistically significant. Compared with group B and group C, the degree of brain re-expansion in group A has obvious advantages and significant differences. The effective rates of the three groups were 83.7%, 58.5%, and 56.7%, respectively. There were 28 cases of subcutaneous hydrops in group A and 22 cases of subcutaneous hydrops in group B after operation, and no other serious complications.

Conclusion

The SDD is safe and effective for infant patients with intracranial infections through fluid replacement and intrathecal antibacterial. Hyperbaric oxygen is effective as an adjuvant therapy to promote brain re-expansion.

De Sanctis-Cacchione Syndrome with Subdural Effusion: A Rare Case from India with Review of Literature

De Sanctis-Cacchione syndrome (DCS) formerly known as xerodermic idiocy is characterised by cutaneous photosensitivity, microcephaly, mental retardation, short stature, hypogonadism, spasticity, peripheral neuropathy and sensorineural deafness. Here in, we present the case of a four and half years old male child with features of severe acute malnutrition (SAM) with a typical bird like facies and sunken eyes who had history of photosensitive pruritic pigmentary skin lesions on sun exposed areas from a very early age of six months. Gross developmental delay, ataxia, microcephaly, short stature, hypogonadism and cachectic wasting were identified on examination and hypertransaminasemia and hypothyroidism were recorded from biochemical profile. Subsequent visual evoked response and brainstem evoked response audiometry revealed anterior visual pathway dysfunction and bilateral profound sensorineural hearing loss. Magnetic resonance imaging of brain yielded subdural effusion with mass effect in addition to cerebro-cerebral atrophy and demyelination. Skin biopsy further detected dysplastic changes and early signs of squamous cell carcinoma (SCC). Although few cases are reported sporadically throughout the world, to our best of knowledge till date only 11 such cases have been reported completely in Indian medical literature which makes our case report the 12th one with distinctive novel association of subdural effusion.

Rectal dural metastasis masquerading as chronic subdural hematoma: illustrative case

BACKGROUND

Intracranial dural metastasis causing subdural hematoma formation is a rare clinical entity associated with significant morbidity and mortality. A 61-year-old female patient known to have rectal signet ring cell carcinoma presented with cranial computed tomography scan findings of bilateral subdural hematoma. She underwent evacuation of the hematoma with dural biopsy, which showed tumor emboli consistent with colorectal origin. There was an early recurrence of the subdural collection, and an emergency subdural-peritoneal shunt insertion was done; however, there was no sustained clinical improvement. This work reports the first case of rectal dural metastasis presenting as chronic subdural hematoma and discusses the clinical course and current literature.

OBSERVATIONS

The cases described in these studies are consistent with the clinical course of our patient; that is, evacuation of the subdural hematoma provided temporary clinical improvement and re-accumulation occurred within 3 days.

LESSONS

The authors recommend maintaining a high index of suspicion in this select group of patients, including prompt discussion about treatment plans with the patient's family.

Java in a 3-month-old infant complicated by dilation of subarachnoid spaces, subdural effusion and right-sided hemiparesis

A 3-month-old female infant with meningo-encephalitis caused by Salmonella enterica Paratyphi B var. Java is described. The aetiological agent was confirmed in six CSF samples; however, none of the blood or faecal samples was positive for the same pathogen. The presence of the bacteria was confirmed in the CSF by culture, serology and Multiplex PCR assay. The infant developed dilated subarachnoid spaces and right-sided hemiparesis associated with the persistent bacterial meningo-encephalitis. She was re-admitted 2 weeks after recovery and initial discharge from hospital owing to recurrence of S. enterica Paratyphi B bacteria in the CSF and the development of large bilateral subdural effusions in the brain. Computed tomography and the clinical course confirmed dynamically progressive meningo-encephalitis. Following further parenteral antibiotics and symptomatic treatment, the child's condition improved. After a total of 24 days in the PICU, she was sufficiently improved to be discharged with a residual right-sided hemiparesis. However, sadly she died a week after discharge.Abbreviation: ALT: alanine aminotransferase; API: analytical profile index 20 E-test; AST: aspartate aminotransferase; CRP: C-reactive protein; CSF: cerebrospinal fluid; CT: computed tomography; EUCAST: European Committee on Antimicrobial Susceptibility Testing; MDCT: multi-detector computed tomography; PCR: polymerase chain reaction; PICU: paediatric intensive care unit; RBC: red blood cells; VITEK: automated instrument for identification/antimicrobial susceptibility testing; WBC: white blood cells.

Effectiveness and Safety of Pressure Dressings on Reducing Subdural Effusion After Decompressive Craniectomy

OBJECTIVE

Decompressive craniectomy as a treatment is often used in the rescue treatment of critically ill patients in neurosurgery; however, there are many complications after this operation. Subdural effusion is a common complication after decompressive craniectomy. Once it occurs, it can cause further problems for the patient. Therefore, the purpose of this study was to explore the safety and effectiveness of pressure dressings for subdural effusion after decompressive craniectomy.

METHODS

Patients who underwent decompressive craniectomy in our hospital from January 2016 to January 2021 were included in this study, and all patients were followed up for 6 months or more. After the operation, the patients were divided into two groups according to whether they received a pressure dressing or a traditional dressing. Subdural effusion, cerebrospinal fluid leakage, hydrocephalus and other complications were compared between the two groups, and the differences in hospital duration, cost and prognosis between the two groups were analyzed.

RESULTS

A total of 123 patients were included in this study. Among them, 62 patients chose pressure dressings, and 61 patients chose traditional dressings. The incidence of subdural effusion in the pressure dressing group was significantly lower than that in the traditional dressing group (P<0.05). There was no difference between the two groups in cerebrospinal fluid leakage and hydrocephalus (P > 0.05). In addition, the length of hospital stay and the total cost in the pressure dressing group were significantly lower (P<0.05).

CONCLUSION

Pressure dressing can effectively reduce the occurrence of subdural effusion after decompressive craniectomy, and it does not increase the occurrence of other cerebrospinal fluid-related complications.

Endoscopic-assisted surgery for skull defects with subdural effusion

Introduction

Subdural effusion is a common complication that occurs after decompressive craniectomy. According to the endoscopy results, the formation mechanism of subdural effusion after decompressive craniectomy was discussed.

Aim

The morphological structure of subdural effusion in skull defects was observed with endoscopy, and endoscopic-assisted surgery was performed for subdural effusion.

Material and methods

From January 2018 to March 2020, 19 cases of skull repair and treatment of subdural effusion were performed. The external wall of the capsule was kept intact during the operation, subdural effusion and surgical procedure of the subdural effusion under an endoscope could be observed, and the results of endoscopic observation were described and recorded. A hemostasis gauze was placed between the two layers of the subdural effusion cavity. Another 13 cases of skull defects with subdural effusion treated without endoscopy during the same time period were enrolled in the study as the control group. The postoperative disappearance of effusion and the incidence of postoperative complications were compared between the two groups.

Results

Analysis with an endoscope revealed that all cases of subdural effusion in skull defects presented capsules. The main structures included the outer wall, boundary, inner wall, and fistula. The outer wall was made up of new tissue that had formed after removing the bone flap under the skin flap by artificial peeling under the condition of keeping the whole cavity. The inner wall consisted of thickened arachnoid, dura, and artificial dura. It presented with neovascularization networks, which showed a tendency to form new membrane structures through mutual adhesion and fusion. The inner and outer wall of the skull had fused to form the boundary of the cavity. Cerebrospinal fluid fistulas were detected in 31.6% of the internal walls. Subdural effusion was effectively treated in both the experimental group and the control group. Compared with the control group, complications in the experimental group were significantly reduced.

Conclusions

The effusion cavity can be divided into three types based on its structural characteristics: fistula type, membrane type, and closed type. In this study, the formation mechanism of skull defects combined with subdural effusion was explored. This represents a new method for treating subdural effusion in which hemostasis gauze is placed between the two layers of the effusion cavity and cerebrospinal fluid fistula under an endoscope, which can effectively reduce the incidence of postoperative complications.

Computed tomography findings after head injury preceding chronic subdural hematoma

OBJECTIVE

Head CT is sometimes performed immediately after minor head injury; however, which cases develop into chronic subdural hematoma (CSDH) remains unclear. Here, the authors retrospectively reviewed the rare cases of CSDH treated surgically in which early head CT had been performed after the initial head trauma.

METHODS

A total of 172 patients (133 male and 39 female, median age 76 years) underwent surgery for CSDH at Gunma University Hospital between April 2010 and December 2017. Among these patients were 23 who had visited Gunma University Hospital or a nearby hospital and had undergone head CT within 7 days after the initial head trauma. Characteristics of the initial head CT were examined to identify indicators of subsequent CSDH.

RESULTS

Among the 23 CSDH cases (17 male and 6 female, median age 80 years), CT scans were obtained on the day of the initial injury (day 0) in 19 cases (25 sides) and 1-7 days after injury in 12 cases (19 sides); scans were obtained during both periods in 8 cases (12 sides), so that a total of 44 sides were examined. These CT scans were divided into two groups according to when they were obtained; cases in which scans were taken during both periods were included in both groups. Head CT performed on the day of injury showed normal findings in 5 (20%) of 25 sides, thin subdural effusion (SDE) ≤ 6 mm in 16 (64%) of 25 sides, thick SDE > 6 mm in 3 (12%) of 25 sides, and acute subdural hematoma (ASDH) in 1 (4%) of 25 sides. CT from 1-7 days after trauma showed thick SDE in 9 (47%) of 19 sides, thin SDE in 8 (42%) of 19 sides, and ASDH in 2 (11%) of 19 sides. A high-density line in the lateral direction (onion skin-like) was found between the skull and the brain in 9 (35%) of 26 sides with SDE on initial CT 0-7 days after the injury.

CONCLUSIONS

ASDH was not a common cause of CSDH. Head CT at the time of trauma that precedes CSDH often showed SDE. Such SDE that precedes CSDH was often close to the detection limit of CT immediately after the injury but became more apparent from the day after the injury.

An Unusual Presentation of Kikuchi-Fujimoto Disease with Recurrent Subdural Effusion

A 24-year-old man complained of a right temporal headache for four weeks. The patient denied any trauma or previous anticoagulation use. He also reported tender right facial swelling. His physical exam was unrevealing except for right cranial nerve (CN) VI palsy, right parotid enlargement, and cervical adenopathy. Laboratory findings were significant for mild leukopenia at 3300 cells/uL. The computed tomography (CT) scan obtained showed a chronic left subdural effusion with a 4 mm midline shift and confirmed right parotid enlargement and cervical lymphadenopathy. Surgical burr hole evacuation was done and the fluid was sent for wound culture analysis. The infectious diseases service recommended initiating antibiotics, which were later stopped due to cerebrospinal fluid (CSF) cultures with no growth of any organisms. His CN VI palsy resolved during admission. The patient was discharged with follow-up for biopsy. The patient was lost to follow-up. The patient presented to the emergency department (ED) three months later, with a left-sided frontal headache. A repeat CT scan showed a new, right-sided fluid collection outside the brain parenchyma. Burr hole evacuation was done again and purulent fluid was drained. Antibiotics were held this time, but anti-tuberculous therapy was initiated empirically. The otolaryngology service was consulted and a lymph node biopsy was performed. The pathology showed histiocytic necrotizing lymphadenitis. A dural biopsy was done as well and was consistent with histiocytic necrotizing lymphadenitis involving the dura. Cultures from the subdural fluid did not grow any organism. The patient remained neurologically intact. He improved after surgery was done to drain the fluid and was managed by analgesics. The cultures from the extra-parenchymal fluid collection remained negative for pathogens and tuberculous mycobacteria. The patient was discharged with rheumatology clinic follow-up. He saw the rheumatologist six weeks after the discharge. During his clinic visit, the patient reported no recurrence of headaches, fevers, rash, or joint pain. Our patient had a rare presentation of Kikuchi-Fujimoto disease, in which he had a subdural fluid collection resulting in neurological complications that required surgical intervention.

Recurrent, symptomatic, late-onset, contralateral subdural effusion following decompressive craniectomy treated by cranial strapping

Subdural effusions following decompressive craniotomy for trauma are usually benign, ipsilateral to the craniotomy and resolve spontaneously. Far less common and more dangerous are contralateral subdural effusions causing external cerebral herniation. We report a case of recurrent contralateral effusion and highlight the management dilemmas. Arachnoid tear is probably the cause of these collections. Contralateral subdural effusions should be suspected in patients who have delayed neurological deterioration after an initial improvement particularly in the setting of increased "flap bulge" though they may also be found in patients who remain moribund after initial surgery. There are no clear-cut guidelines on their management due to their rarity. A variety of options like subduro-peritoneal shunt and drainage with simultaneous cranioplasty may be tried. In situations where resources or patient compliance is an issue, tapping the effusion followed by cranial strapping may be tried as was done in our case.

Enhancing subdural effusions mimicking acute subdural hematomas following angiography and endovascular procedures: report of 2 cases

Hyperdense enhancing subdural effusion due to contrast extravasation has been recently described as a potential mimicker of acute subdural hematoma following a percutaneous coronary procedure. Herein, the authors report on 2 patients who presented with subarachnoid hemorrhage from ruptured cerebral aneurysms and who developed enhancing subdural effusions mimicking acute subdural hematomas after angiography and endovascular coil placement. In 1 case, the subdural effusions completely cleared but recurred after a second angiography. CT attenuation values higher than expected for blood, as well as the evolution of the effusions and density over time, allowed for differentiation of enhancing subdural effusions from acute subdural hematomas.

Surgical management of the patients with chronic subdural haematoma and contralateral subdural effusion: Operation or no-operation?

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.

Severe neurologic involvement of Degos disease in a pediatric patient

A 14-year-old male presented with paresthesias on the right upper and lower extremities, headache, and vomiting. In addition to worsening paresthesia and weakness on the right side of his body, blurred vision, fever, and skin lesions developed. He also had skin lesions characterized with 3-10 mm papules with a white atrophic center surrounded by pink rim mostly on the trunk and lower extremities. Brain magnetic resonance imaging showed chronic subdural effusion and encephalomalacia of the left cerebral hemisphere. Cerebrospinal fluid (CSF) examination revealed increased protein levels. Electromyography was consistent with diffuse polyradiculoneuropathy. Skin biopsy confirmed the diagnosis of a rare vasculopathy: Degos disease. A case presenting with chronic subdural effusion, encephalomalacia, elevated CSF protein, and polyradiculopathy should be carefully examined for skin lesions, which may suggest the diagnosis of Degos disease.

"Rabbit Ear" scalp deformity caused by massive subdural effusion in infant following bilateral burr-hole drainage

Subdural effusion (SDE) in an infant is a rare clinical scenario, which may be secondary to a variety of etiologies. Massive SDE is an extremely rare complication of head injury. It usually runs a self-limiting course. Though neurosurgical intervention is occasionally needed, different methods of surgical procedure for management includes burr-hole alone, burr-holes with subdural drain placement, twist drill craniotomy with drain and even craniotomy. The authors report a rare case of progressive massive SDE, which despite bilateral burr-hole placement and drainage failed and presented with visual deterioration and massive bulge of scalp at burr-hole sites producing rabbit ear sign in a 10 month old infant. Ultimately cystoperitoneal shunt was carried out in a desperate attempt to prevent impending rupture of scalp sutures at sites of previous burr-hole placement. Astonishingly not only complete resolution of hygroma, but visual recovery also took place. Patient is doing well at 6 months following shunt with regaining normal vision and appropriate developmental milestones. A magnetic resonance imaging scan of brain at last follow-up revealed mild ventriculomegaly with subduro-peritoneal shunt in situ and rest of brain was unremarkable. Such cases have not been reported in literature until date.

Normal pressure subdural hygroma with mass effect as a complication of decompressive craniectomy

BACKGROUND

Subdural posttraumatic collections are called usually Traumatic Subdural Hygroma (TSH). TSH is an accumulation of cerebrospinal fluid (CSF) in the subdural space after head injury. These collections have also been called Traumatic Subdural Effusion (TSE) or External Hydrocephalous (EHP) according to liquid composition, or image features. There is no agreement about the pathogenesis of these entities, how to define them or if they are even different phenomena at all.

CASE DESCRIPTION

We present a case of a complex posttraumatic subdural collection, the role of cranioplasty as definite solution and review the literature related to this complication.

CONCLUSION

Patients who undergo decompressive craniectomy (DC) have a risk of suffering a subdural collection of 21-50%. Few of these collections will become symptomatic and will need evacuation. When this happens, cranioplasty might be the definitive solution.
