Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries. Br J Surg 2023; 110:804-817. [PMID: 37079880 PMCID: PMC10364528 DOI: 10.1093/bjs/znad092] [Citation(s) in RCA: 14] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 03/03/2023] [Accepted: 03/06/2023] [Indexed: 04/22/2023]
Abstract
BACKGROUND Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. METHODS This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low-middle-income countries. RESULTS In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of 'single-use' consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low-middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. CONCLUSION This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high- and low-middle-income countries.

Abstract
Background Gender-affirming hormone therapy is critical to the management of transgender persons. Cyproterone acetate (CPA) is a synthetic, progesterone-like compound commonly used in high doses as gender-affirming progestogen therapy in transgender women. An association between high-dose CPA and the development and growth of intracranial meningioma, including case reports in transgender women, has been described. This systematic review summarizes these cases at the patient level and discusses their management. Methods This systematic review was registered with PROSPERO (CRD42020191965). A detailed search of the PubMed, EMBASE, and Web of Science electronic bibliographic databases was performed (inception-December 20, 2020). Two review authors independently completed screening, data extraction, and risk of bias assessment in duplicate. Results Nine records were included describing (n=12) individual case reports and (n=35) intracranial meningiomas. The median age at presentation was 48 years (interquartile range [IQR], 43-55 years), most frequent daily CPA doses were 50 mg/day (n=5) and 100 mg/day (n=5), and the median duration of CPA use was 9.5 years (IQR, 6.5-17.5 years). Multiple meningiomas were common (n=7). For most cases (n=10), surgical resection was the initial preferred management strategy, but two were successfully managed by CPA cessation. Conclusions Transgender women receiving high doses of CPA may be at increased risk of intracranial meningioma development and/or growth, although this remains a rare disease. For presumed CPA-associated meningioma, drug cessation appears to be an appropriate management strategy when surgery is not imminently required to manage raised intracranial pressure or prevent neurological deterioration. Given the importance of gender-affirming hormone therapy to transgender persons, a suitable alternative hormone regimen should be offered, although the use of CPA in both high doses and for prolonged periods of time is now in decline.

Abstract
Abstract
BACKGROUND
Systematic reviews and meta-analyses constitute the highest level of research evidence and for a disease with limited clinical trial activity, are often relied upon to help inform clinical practice. This review of reviews evaluates both the reporting & methodological quality of meningioma evidence syntheses.
MATERIAL AND METHODS
Potentially eligible meningioma reviews published between 1st January 1990 and 31st December 2020 were identified from eight electronic databases. Inclusion required the study to meet the Cochrane guideline definition of a systematic review or meta-analysis. Reviews concerning neurofibromatosis type 2, spinal and pediatric meningiomas were excluded. The reporting and methodological quality of articles were assessed against the following modified guidelines: Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA), A MeaSurement Tool to Assess Systematic Reviews (AMSTAR2) and the Risk of Bias in Systematic Reviews (ROBIS) guidelines.
RESULTS
117 systematic reviews were identified, 57 of which included meta-analysis (48.7%). The number of meningioma systematic reviews published each year has increased with 63 studies (53.9%) published between 01/2018 and 12/2020. A median of 17 studies (IQR 9–29) were included per review. Impact factor of journals publishing a systematic review with or without a meta-analysis was similar (median 2.3 vs 1.8, P=0.397). The mean PRISMA scores for systematic reviews with a meta-analysis was 21.11 (SD 4.1, 78% adherence) and without was 13.89 (SD 3.4, 63% adherence). Twenty-nine systematic reviews with meta-analysis (51%) and 11 without meta-analysis (18%) achieved greater than 80% adherence to PRISMA recommendations. Methodological quality assessment using AMSTAR2 revealed one study (0.9%) as high quality whilst 111 (94.8%) studies were graded as critically low. One hundred and two articles (87.2%) did not utilize a comprehensive search strategy as defined by the AMSTAR2 tool. Ninety-nine studies (84.6%) obtained a high level of concern for potential bias as per the ROBIS assessment. One hundred and eight articles (92.3%) failed to present information that a protocol had been established prior to study commencement and 76 articles (65.0%) did not conduct a risk of bias assessment. Across the three tools, domains relating to the establishment of a protocol prior to review commencement and conducting appropriate risk of bias assessments were frequently low scoring.
CONCLUSION
Overall reporting and methodological quality of meningioma systematic reviews was sub-optimal. Established critical appraisal tools and reporting guidelines should be utilized a priori to assist in producing high-quality systematic reviews.

Abstract
Abstract
BACKGROUND
Long-term Health-Related Quality of Life (HRQoL) is an important measure of patient wellbeing. There is a paucity of studies evaluating HRQoL in meningioma patients.
MATERIAL AND METHODS
Cross-sectional study of adult patients with an incidental or symptomatic intracranial meningioma. Patients with less than 5 years of follow-up, a history of craniospinal radiation or neurofibromatosis type 2 were excluded. HRQoL was evaluated with SF-36, EORTC QLQ-C30 and EORTC QLQ-BN20 questionnaires. Outcome determinants were evaluated using a multi-variable linear regression analysis, adjusted for patient, tumour and treatment characteristics, and duration of follow-up.
RESULTS
699 patients were invited to participate and 246 responded: 118 (48%) had an incidental meningioma. Mean age at diagnosis was 56.8 years (SD=13) and 81% were female. Median time from diagnosis to completion of questionnaire was 8.5 years (IQR 6.8–11.5). During follow-up, 158 patients (64.2%) had at least one operation for their meningioma and 47 patients (19.1%) had radiotherapy. Of those operated, 126 (79.7%) had WHO grade 1 and 24 (15.2%) had grade 2 meningiomas. Compared to normative population values, meningioma patients reported a worse SF-36 general health score (mean 61.9 vs 56.5, P=0.003) but a similar QLQ-C30 global health score (mean 62.3 vs 65.8, P=0.039), worse SF-36 and QLQ-C30 physical functioning scores (mean 74.1 vs 64.6, P<0.001 and mean 81.8 vs 76.5, P=0.007) and similar SF-36 and QLQ-C30 emotional health scores (mean 72.2 vs 70.9, P=0.367 and mean 71.0 vs 71.9, P=0.960). QLQ-C30 cognitive functioning was worse (mean 80.5 vs 71.4, P<0.001). Compared to the meningioma literature, QLQ-BN20 seizure burden was similar (mean 2.0 vs 1.6, P=0.760). A worse performance status at diagnosis was associated with an inferior QLQ-C30 global health score (β-coefficient=-4.9 [95% CI -9.1-(-)0.6] P=0.024). Number of surgeries was significantly associated with a worse QLQ-C30 cognitive functioning score (β-coefficient=-7.0 [95% CI -13.2-(-)0.9], P=0.025). Anti-epileptic drug use was associated with a significantly worse QLQ-C30 emotional health score (β-coefficient=-10.9 [95% CI -21.7-(-)0.01], P=0.050).
CONCLUSION
Meningioma patients have long-term HRQoL impairments affecting their physical and cognitive functions. An understanding that multiple surgeries affects cognitive function, and the need for anti-epileptic drugs equate to poorer emotional health, could help target appropriate therapies and support in the future.

Abstract
Abstract
BACKGROUND
Meningioma is the commonest primary brain tumour. Despite surgery, meningiomas can recur. Surgery is usually the first line treatment for recurrent meningioma. The aim was to determine the risk factors associated with clinical outcomes (performance status, morbidity, mortality, recurrence) following re-operation for recurrence of intracranial meningioma.
MATERIAL AND METHODS
Retrospective cohort study (1998–2018). Eligible patients had reoperation for local recurrence of a previously operated meningioma. Collected data included baseline clinical and imaging characteristic. Primary outcome measure was performance status after each reoperation. Secondary outcome measures were medical and surgical morbidity, recurrence-free survival (RFS) and overall survival (OS).
RESULTS
Fifty-eight patients were eligible (37 female, mean age at 1st re-operation 56.1 years (SD=11.6)). Eleven patients (19.6%) had 2 re-operations and 3 patients (5.4%) had 3 re-operations. Median follow up was 128.5 months (IQR=73–194.5). Median time to 1st recurrence and 1st re-operation were 36.5 (IQR=24.3–81.0) and 43.8 months (IQR=20.3–103.4), respectively. Fifteen patients (26.8%) had worse performance status after 1st reoperation, compared to 5.4% (n=3) after the primary operation. Complication rate was 32.1% (n=18) after the primary operation compared to 48.2% (n=27) after 1st reoperation. At primary operation, there were 29 (51.8%) grade 1, 24 (42.9%) grade 2, and 1 (1.8%) grade 3 tumours. Median RFS after first re-operation was 36.5 months (95% CI 29.3–43.9). Median OS was 312 months (95 % CI 257.8–366.2). Increased number of post-operative complications were a risk factor for worsened performance status following reoperation (OR 2.2 [95% CI 1.1–4.6], P=0.029).
CONCLUSION
Re-operation is associated with a worse performance status and increased risk of complications. Re-operating meningiomas for radiological recurrence without symptoms increases patient morbidity. Shared-care management decision should be made with patients when considering operating for radiological recurrence only.

Abstract
Abstract
BACKGROUND
Resection of meningioma leaves residual solid tumour in ~25% of patients. Selection for further treatment and follow-up strategy may benefit from knowledge of volumetric growth and associated prognostic factors.
MATERIAL AND METHODS
Growth rates were assessed using a linear mixed effects model, in a retrospective adult cohort that underwent subtotal resection of meningioma (2004–2018). Endpoints were re-treatment, end of follow-up or death. Cox regression analysis was used to identify prognostic factors for progression, defined using the Response Assessment in Neuro-Oncology (RANO) volumetric criteria.
RESULTS
236 patients were included. Mean age at surgery was 56.3 years (SD=13.7) and 73.7% were female. WHO grades were 1 (n=195, 82.6%), 2 (n=40, 16.9%) and 3 (n=1, 0.5%). Adjuvant fractionated radiotherapy (fRT) was administered to 34 patients (14.4%), with no propensity towards higher WHO grade or residual volume. Median pre-operative meningioma and post-operative residual volumes were 34.0cm3 (IQR 16.0–63.0) and 2.0cm3 (IQR 0.8–5.2), respectively. Median follow-up was 64 months (IQR 42–104). Median absolute growth rate (AGR) and relative growth rate (RGR) were 0.1cm3/year and 4.3%/year, respectively. According to RANO criteria, 132 (55.9%) patients progressed, of which 13 (9.8%) developed symptoms. Median progression-free survival was 56 months (95% CI 43.1–69.0). Multivariable analysis identified adjuvant fRT (HR 1.7, [95% CI 1.0–2.8], P=0.046), skull base location (HR 1.5, [95% CI 1.0–2.4], P=0.047) and Ki-67 index (HR 3.7 [95% CI 1.3–10.8], P=0.017) as prognostic factors for volumetric progression. WHO grade was not significant (HR 1.0, [95% CI 0.5–1.7], P=0.905). Forty-nine patients who progressed (37.1%) underwent further treatment: fRT (n=19), re-operation (n=15), Stereotactic radiosurgery (SRS) (n=10) and surgery+adjuvant fRT (n=5). Of those, 8 (16.3%) progressed further (after re-operation [n=6] and SRS [n=2]). Seven were treated with a 2nd re-operation (n=3), fRT (n=3), and SRS (n=1). One patient progressed after a 2nd reoperation and was treated with SRS, after which they remained stable. Median survival was not reached. 5- and 10-year overall survival (OS) was 96% and 86% respectively.
CONCLUSION
Growth rates of a residual meningioma vary with a dichotomy observed in progression rates. Half of patients with a residual meningioma showed radiological progression requiring multiple treatment to control the tumour. The other half demonstrate a more indolent course. Skull base location and higher Ki67 are important prognostic factors for progression and therefore, should be considered to stratify patients for adjuvant radiotherapy.

Abstract
We present a 69-year-old transgender woman who underwent gender-affirming surgery in 1998 and gender-affirming hormone therapy (cyproterone acetate (CPA) and estradiol) since this time. Following an MRI scan to investigate tremor in 2013, an incidental left anterior clinoid and right petrous meningioma were identified. Subtotal surgical resection was achieved for the anterior clinoid meningioma (WHO grade 1, meningothelial subtype). At follow-up in 2016, an olfactory groove meningioma and left greater wing of sphenoid meningioma were identified. By 2017, both tumours, along with the petrous meningioma, demonstrated significant growth. In 2018, clinical decline was evident and MRI demonstrated further tumour growth. Surgery was scheduled and the olfactory groove meningioma was completely resected (WHO grade 2, chordoid subtype). Hormones were stopped, after which regression of the petrous meningioma was observed. This case demonstrates an association between high-dose CPA and estradiol and the development, growth and regression of meningiomas in a transgender woman.

Abstract
Background: Cerebrovascular disorders represent a group of uncommon, heterogeneous, and complex conditions in children. We reviewed the screening practice for the detection of cerebrovascular disorder in asymptomatic children referred to our neurovascular service on the basis of a positive family history and parental and/or treating physician concern.Methods: Retrospective case-note review of referrals to our neurovascular service (July 2008-April 2018). Patients were included if the referral was made for screening, on the basis of a positive family history of cerebrovascular disorder. Symptomatic children, those with previous cranial imaging, or children under the care of a clinical geneticist (i.e. due to the child or their relative having HHT or mutations in KRIT1) were not eligible for inclusion.Results: Forty-one children were reviewed, 22 males (Median age 10.7 years, range 0.6-15.6 years). This represented 22% of the total number of referrals over a 10-year period. Twenty-nine children had an MRI/MRA brain. Twenty-eight children were referred due to a family history of intracranial aneurysm and/or subarachnoid haemorrhage, but only two had two first-degree relatives affected. Ten children were referred due to a family history of arteriovenous malformation. Three children were referred due to a family history of stroke. No cerebrovascular disease was detected during the study period (n = 29).Conclusions: Parental and/or physician concern generated a substantial number of referrals but no pathology was detected after screening. Whilst general screening guidance exists for the detection of intracranial aneurysms, consensus guidelines for the screening of children with a positive family history do not, but are required both to guide clinical practice and to assuage parental and/or physician concerns.

Abstract
Both acute and chronic subdural haematomas typically occur following trauma. Non-traumatic causes are less common, but aetiologies include arteriovenous malformation, intracranial aneurysm rupture, tumour-associated haemorrhage and coagulopathies. May-Hegglin anomaly is an example of a coagulopathy, which is caused by a mutation in the gene encoding non-muscle myosin heavy chain 9 (MYH9) and therefore falls into a group of diseases referred to as MYH9-related diseases (MYH9-RD). The symptomology of MYH9-RD is often mild, and patients tend to experience epistaxis, gingival bleeding and bruising. Life-threatening haemorrhage rarely occurs. In this short report, we describe a patient with known May-Hegglin anomaly who presented with a potentially life-threatening, spontaneous subdural haematoma requiring surgery on two occasions. This is only the second such report in the literature, and the first of spontaneous and recurrent haemorrhage in association with May-Hegglin anomaly.

Abstract
OBJECTIVE Complications in pediatric neurooncology surgery are seldom and inconsistently reported. This study quantifies surgical morbidity after pediatric brain tumor surgery from the last decade in a single center, using existing morbidity and outcome measures. METHODS The authors identified all pediatric patients undergoing surgery for an intracranial tumor in a single tertiary pediatric neurosurgery center between January 2008 and December 2018. Complications between postoperative days 0 and 30 that had been recorded prospectively were graded using appropriate existing morbidity scales, i.e., the Clavien-Dindo (CD), Landriel, and Drake scales. The result of surgery with respect to the predetermined surgical aim was also recorded. RESULTS There were 477 cases (364 craniotomies and 113 biopsies) performed on 335 patients (188 males, median age 9 years). The overall 30-day mortality rate was 1.26% (n = 6), and no deaths were a direct result of surgical complication. Morbidity on the CD scale was 0 in 55.14%, 1 in 10.69%, 2 in 18.66%, 3A in 1.47%, 3B in 11.74%, and 4 in 1.05% of cases. Morbidity using the Drake classification was observed in 139 cases (29.14%). Neurological deficit that remained at 30 days was noted in 8.39%; 78% of the returns to the operative theater were for CSF diversion. CONCLUSIONS To the authors' knowledge, this is the largest series presenting outcomes and morbidity from pediatric brain tumor surgery. The mortality rate and morbidity on the Drake classification were comparable to those of published series. An improved tool to quantify morbidity from pediatric neurooncology surgery is necessary.

Abstract
ObjectivesTo measure complications of paediatric neurooncology surgery using the Clavien Dindo grading scale, and identify predictors of surgical morbidity.DesignRetrospective review of prospectively collected data.SubjectsAll paediatric patients treated with craniotomy for excision of intracranial tumour between 2008 and 2017 in a single tertiary paediatric neurosurgery centre.MethodsDemographics, surgical details and perioperative complications were prospectively recorded between 0 and 30 days post operatively. These were retrospectively graded using the CD scale. Data analysis was done in R using logistic regression. Significance was defined as p<0.05ResultsBetween 3/1/2008 and 21/12/2017 there were 322 operations, on 254 patients (142 Male). Median age at surgery was 9 years (IQR 4–13 years). 48% were without complication on the CD scale. Maximum CD grade complication for each procedure was 1 in 11%, 2 in 19%, 3A in 2%, 3B in 14%, and 4 in 0.6% of operations. 30 day mortality was 0.9%. CD grade of 3B or over was associated with infratentorial tumours (OR 2.24; CI 1.10–4.68; p=0.004) and WHO grade III tumours (OR 4.12; CI 1.56–10.86; p=0.028).ConclusionsComplications in paediatric neurooncology surgery are common overall, but our results are favourable in comparison to the literature. The CD scale has limitations in neurosurgery but gives insight into the health economic impact of complications. Infratentorial tumours, and WHO grade III tumours were associated with increased morbidity.

Thirty-one children had an MRI/MRA brain. One child subsequently had uncomplicated digital subtraction angiography. Thirty children were referred due to a family history of subarachnoid haemorrhage, of which 17 had a single first-degree relative, and two had two first-degree relatives. Nine children were referred with a family history of arteriovenous malformation, (2 were associated with hereditary haemorrhagic telangiectasia). Five children were discussed due to a family history of non-specific haemorrhagic stroke. Seven children had a history of headache, (4 were prescribed Pizotifen for migraine). No neurovascular pathology was detected following screening within our cohort.ConclusionsA consensus screening policy does not exist but is required both to guide clinical practice and to assuage parental or patient concerns. We will survey UK paediatric centres to commence this process.

Abstract
ObjectivesPrimary spinal tumours in children are rare and poorly understood; we review 10 years of surgical experience.DesignRetrospective review of prospectively maintained database.SubjectsChildren receiving surgical management of primary spinal tumours in a single, tertiary paediatric neurosurgery centre.MethodsOperations for primary spinal tumours were abstracted from our prospectively maintained surgical database and supplemented with data from case notes, operative records, and imaging studies.ResultsBetween 2008 and 2017, 37 procedures were performed on 29 patients (19 male; Median age 7.5 years, IQR 2–11.25). 28 had their primary procedure in our unit: 21 excisions, and 7 biopsies (of which 5 proceeded to further surgery). Tumours were classified as extradural (10), intradural extramedullary (3), intradural intramedullary (11) or bony (4). Tumours were found at the following levels: Cervical (8; 29%), Cervicothoracic (2; 7.1%), Thoracic (10; 36%), Thoracolumbar (3; 11%), Lumbar (2; 7.1%), Lumbosacral (2; 7.1%) and Sacral (1; 3.6%). Histology comprised: Pilocytic Astrocytoma (6), Other Astrocytoma (4), Schwannoma (3), Ewing Sarcoma (2), Langerhans cell histiocytosis (2), Lymphoma (2), Neurofibroma (2), and others (7) including one Myxopapillary Ependymoma.ConclusionsThe rarity and heterogeneity of paediatric spinal tumours makes treatment challenging. We propose a national online registry including a tissue bank, and invite collaboration with other units.

Abstract
INTRODUCTION Optic pathway/hypothalamic gliomas (OPHGs) are generally benign but situated in an exquisitely sensitive brain region. They follow an unpredictable course and are usually impossible to resect completely. We present a case series of 10 patients who underwent surgery for OPHGs with the aid of intra-operative MRI (ioMRI). The impact of ioMRI on OPHG resection is presented, and a role for ioMRI in partial resection is discussed. METHODS Ten patients with OPHGs managed surgically utilising ioMRI at Alder Hey Children's Hospital between 2010 and 2013 were retrospectively identified. Demographic and relevant clinical data were obtained. MRI was used to estimate tumour volume pre-operatively and post-resection. If ioMRI demonstrated that further resection was possible, second-look surgery, at the discretion of the operating surgeon, was performed, followed by post-operative imaging to establish the final status of resection. Tumour volume was estimated for each MR image using the MRIcron software package. RESULTS Control of tumour progression was achieved in all patients. Seven patients had, on table, second-look surgery with significant further tumour resection following ioMRI without any surgically related mortality or morbidity. The median additional quantity of tumour removed following second-look surgery, as a percentage of the initial total volume, was 27.79% (range 11.2-59.2%). The final tumour volume remaining with second-look surgery was 23.96 vs. 33.21% without (p = 0.1). CONCLUSIONS OPHGs are technically difficult to resect due to their eloquent location, making them suitable for debulking resection only. IoMRI allows surgical goals to be reassessed intra-operatively following primary resection. Second-look surgery can be performed if possible and necessary and allows significant quantities of extra tumour to be resected safely. Although the clinical significance of additional tumour resection is not yet clear, we suggest that ioMRI is a safe and useful additional tool, to be combined with advanced neuronavigation techniques for partial tumour resection.

Abstract
INTRODUCTION Intraspinal tumours are rare and principally managed surgically. Laminectomy, employed for access to the spinal canal, destroys the posterior tension band leading to a risk of kyphosis. Hemilaminectomy as an alternative may be less destructive, potentially reducing the risk of deformity and causing less post-operative pain. METHOD We investigated this hypothesis by retrospectively reviewing a case series of 56 surgeries for a disparate and unselected group of intraspinal tumours utilizing a laminectomy or hemilaminectomy approach. RESULTS No difference was found in length of operation, completeness of resection, complication rate and Frankel-score improvements. Hemilaminectomy (n = 22) is associated with reduced hospital stay (post-op days) 4.5 (2-6) versus 6 (3-8), (p = 0.026, Mann-Whitney), and a reduction in post-operative morphine use (mg) 10 (3.5-28) versus 30 (10-90), (p = 0.005, Mann-Whitney). Post-operative kyphosis was measured with the Harrison posterior tangent method on T2-weighted sagittal MR images. The average change in kyphosis angle was greater in the laminectomy group compared with the hemilaminectomy group, 3.6 (0.8-6.2) versus 0.4 (-0.2-1.2), statistically significant (p = 0.004, Mann-Whitney). CONCLUSION Hemilaminectomy is as effective an access procedure for the resection of unselected intraspinal tumours as laminectomy, but is associated with shorter post-operative stays, lower analgesic requirements and less post-operative kyphosis.

Endoscopic Third Ventriculostomy in Children with Myelomeningocele: A Case Series. Pediatr Neurosurg 2015; 50:113-8.

Abstract
Hydrocephalus develops in up to 80-90% of children with myelomeningocele (MM) after closure of the defect. Traditionally, ventriculoperitoneal shunts have been used to manage hydrocephalus in these patients. A role for endoscopic third ventriculostomy (ETV) in MM has provoked much debate, principally due to anatomical variants described, which may complicate the procedure. We present 7 cases of children with MM and hydrocephalus undergoing a total of 10 ETV procedures. All patients demonstrated clinical improvement (in acute/subacute cases) or stabilization (in chronic cases). Three patients requiring a second ETV have shown clinical stability and renewed radiological evidence of functioning ventriculostomies in follow-up since reintervention. ETV can be used, albeit cautiously, in selected cases of hydrocephalus associated with MM. However, the frequency with which anatomical variation is encountered and the difficulty of the assessment of success make the procedure more challenging than usual.

MRI findings of intracranial anomalies associated with cephalocele--a case series. Childs Nerv Syst 2014; 30:891-5. [PMID: 24249206 DOI: 10.1007/s00381-013-2319-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2013] [Accepted: 11/05/2013] [Indexed: 11/28/2022]
Abstract
INTRODUCTION Cephalocele is a relatively rare cranial dysraphism characterised by herniation of intracranial structures through the skull. Surgical management is primarily necessary where a risk of infection through communication of the lesion with the intracranial space exists, a risk of rupture, or for cosmetic purposes. Cephalocele is often associated with venous anomalies such as vertical embryonic positioning of the straight sinus, splitting of the superior sagittal sinus, vein of Galen elongation, along with tenting of the tentorium [Morioka et al. Childs Nerv Syst 25:309-315, 2009] PATIENTS Here, we report four cases of cephalocele with pre-operative MRI imaging retrospectively studied, demonstrating associated venous anomalies. Three of these patients went on to have uncomplicated, corrective surgery, while one was managed conservatively. RESULTS All four cases demonstrated the main venous drainage going through a persistent falcine sinus to drain into the superior sagittal sinus. Upward tenting of the tentorium was observed in three cases (cases 1, 3 and 4). Two of our cases demonstrated other venous anomalies frequently reported in the literature, namely splitting of the superior sagittal sinus and absence of the transverse sinus (case 1) and communication of the cephalocele with the superior sagittal sinus and absence of the straight sinus (case 2). CONCLUSION The association between cephalocele and venous anomalies suggests that pre-operative MRI should be mandatory for a full evaluation of a suspicious midline cranial lesion in order to evaluate the safety of corrective surgery.

Foreign body granuloma secondary to ventriculo-peritoneal shunt: a rare scenario with a new insight. Pediatr Neurosurg 2013; 49:236-9. [PMID: 25074235 DOI: 10.1159/000363330] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2013] [Accepted: 04/27/2014] [Indexed: 11/19/2022]
Abstract
Ventriculo-peritoneal shunts are used extensively for the management of hydrocephalus and frequently present with complications such as shunt blockage and infection. Cerebrospinal fluid (CSF) eosinophilia and allergic responses to the shunt itself are rare, poorly understood but increasingly recognised complications. Here, the authors describe a child who required multiple shunt revision surgeries due to extensive scalp tenderness overlying the shunt tubing and persistent severe headaches despite having a normal working shunt and no CSF infection or eosinophilia. Histological investigation of excised tissue during the last shunt revision demonstrated fibrosis with scar tissue and chronic inflammatory infiltrate with foreign body giant cells and few abortive granulomata. This was felt to represent a foreign body reaction to the shunt. A hypoallergenic 'extracted' shunt was trialled (extracted Delta® valve and extracted ventricular and peritoneal catheters; Medtronic) and the child has had no further shunt revisions and is currently asymptomatic 1 year after the insertion.
