RESUMEN
BACKGROUND AND OBJECTIVES: Surgery is widely performed for refractory epilepsy in patients with Sturge-Weber syndrome (SWS), but reports on its effectiveness are limited. This study aimed to analyze seizure, motor, and cognitive outcomes of surgery in these patients and to identify factors associated with the outcomes. METHODS: This was a multicenter retrospective observational study using data from patients with SWS and refractory epilepsy who underwent epilepsy surgery between 2000 and 2020 at 16 centers throughout China. Longitudinal postoperative seizures were classified by Engel class, and Engel class I was regarded as seizure-free outcome. Functional (motor and cognitive) outcomes were evaluated using the SWS neurologic score, and improved or unchanged scores between baseline and follow-up were considered to have stable outcomes. Outcomes were analyzed using Kaplan-Meier analyses. Multivariate Cox regression was used to identify factors associated with outcomes. RESULTS: A total of 214 patients with a median age of 2.0 (interquartile range 1.2-4.6) years underwent surgery (focal resection, FR [n = 87]; hemisphere surgery, HS [n = 127]) and completed a median of 3.5 (1.7-5.0) years of follow-up. The overall estimated probability for being seizure-free postoperatively at 1, 2, and 5 years was 86.9% (95% CI 82.5-91.6), 81.4% (95% CI 76.1-87.1), and 70.7% (95% CI 63.3-79.0), respectively. The overall estimated probability of being motor stable at the same time post operatively was 65.4% (95% CI 58.4-71.2), 80.2% (95% CI 73.8-85.0), and 85.7% (95% CI 79.5-90.1), respectively. The overall probability for being cognition stable at 1, 2, and 5 years was 80.8% (95% CI 74.8-85.5), 85.1% (95% CI 79.3-89.2), and 89.5% (95% CI 83.8-93.2), respectively. Both FR and HS were effective at ensuring seizure control. For different HS techniques, modified hemispherotomy had comparable outcomes but improved safety compared with anatomical hemispherectomy. Regarding FR, partial resection (adjusted hazard ratio [aHR] 11.50, 95% CI 4.44-29.76), acute postoperative seizure (APOS, within 30 days of surgery; aHR 10.33, 95% CI 3.94-27.12), and generalized seizure (aHR 3.09, 95% CI 1.37-6.94) were associated with seizure persistence. For HS, seizure persistence was associated with APOS (aHR 27.61, 9.92-76.89), generalized seizure (aHR 7.95, 2.74-23.05), seizure frequency ≥30 times/month (aHR 4.76, 1.27-17.87), and surgical age ≥2 years (aHR 3.78, 1.51-9.47); motor stability was associated with severe motor defects (aHR 5.23, 2.27-12.05) and postoperative seizure-free status (aHR 3.09, 1.49-6.45); and cognition stability was associated with postoperative seizure-free status (aHR 2.84, 1.39-5.78) and surgical age <2 years (aHR 1.76, 1.13-2.75). DISCUSSION: FR is a valid option for refractory epilepsy in patients with SWS and has similar outcomes to those of HS, with less morbidity associated with refractory epilepsy. Early surgical treatment (under the age of 2 years) leads to better outcomes after HS, but there is insufficient evidence that surgical age affects FR outcomes. These findings warrant future prospective multicenter cohorts with international cooperation and prolonged follow-up in better exploring more precise outcomes and developing prognostic predictive models. CLASSIFICATION OF EVIDENCE: This study provides Class IV evidence that in children with SWS and refractory seizures, surgical resection-focal, hemispherectomy, or modified hemispherotomy-leads to improved outcomes.

PURPOSE: The traditional imaging findings reported in Sturge-Weber syndrome (SWS) include endpoints of cortical injury-cortical atrophy and cortical calcifications-but also what has been termed a "leptomeningeal angiomatosis," the latter recognized and reported as a leptomeningeal enhancement on magnetic resonance imaging (MRI). The objective of this study is to demonstrate through neuropathological correlation that the "leptomeningeal angiomatosis" in patients with Sturge-Weber syndrome (SWS), represents a re-opened primitive venous network in the subarachnoid space that likely acts as an alternative venous drainage pathway, seen separately to abnormal pial enhancement. MATERIALS AND METHODS: Retrospective review of MR imaging and surgical pathology of patients that underwent surgery for epilepsy at a tertiary, children's hospital. A pediatric radiologist with more than 20 years of experience reviewed the MR imaging. Surgically resected brain specimens that had been sectioned and fixed in 10% paraformaldehyde for histologic processing, following processing and paraffin embedding, were cut into 5-µm unstained slides which were subsequently stained with hematoxylin and eosin (H&E). Slides were re-examined by a board-certified pediatric neuropathologist, and histologic features specifically relating to cerebral surface and vascularity were documented for correlation with MR imaging of the resected region performed prior to resection. RESULTS: Five patients were reviewed (3 boys and 2 girls; the median age at the onset of seizures was 12 months (IQR, 7 to 45 months); the median age at surgery was 33 months (IQR, 23.5 to 56.5 months)). Surgical procedures included the following: 4, hemispherotomy (right: 2, left: 2) and 1, hemispherectomy (right). A subarachnoid space varicose network was present on both MRI and histology in 4 patients. Calcifications were seen on both MRI and histology in 3 patients. Abnormal leptomeningeal enhancement was present in 5 patients and seen separately from the subarachnoid vascular network in 4 patients. CONCLUSION: Histopathology confirmed the MRI findings of a subarachnoid space varicose network seen separately from leptomeningeal enhancement and presumed to represent an alternative venous drainage pathway to compensate for maldevelopment of cortical veins, the primary abnormality in SWS. No pial-based angioma was identified.

PRCIS: Long-term intraocular pressure control can be difficult to achieve in eyes with Sturge-Weber syndrome glaucoma. The most commonly performed primary surgery was trabeculotomyin early onset disease and tube shunt implantation in late onset disease. PURPOSE: To compare long-term surgical outcomes of glaucoma associated with Sturge-Weber syndrome (SWS) in eyes with early and late-onset disease. METHODS: Medical records of children with glaucoma associated with SWS who underwent surgical treatment between January 1990 and December 2018 were reviewed. Those diagnosed ≤2 years of age were categorized as early onset while those who were diagnosed >2 years of age were late onset. Failure was defined as intraocular pressure (IOP) >21 mm Hg or reduced <20% below baseline on 2 consecutive follow-up visits after 3 months, IOP ≤5 mm Hg on 2 consecutive follow-up visits, reoperation for glaucoma or a complication, or loss of light perception. RESULTS: Forty-three eyes of 36 children were studied, including 26 eyes in the early-onset group and 17 eyes in the late-onset group. The early-onset group more frequently presented with buphthalmos, corneal edema, and Haab striae, while late-onset group had higher baseline IOP, larger cup-to-disc ratio, and longer axial length. The most commonly performed primary surgery was trabeculotomy (50%) in early-onset group and tube shunt implantation (71%) in late-onset group. The cumulative probability of failure after 5 years follow-up was 50.6% in early-onset group and 50.9% in the late-onset group ( P =0.56). Postoperative complications occurred in 3 eyes (12%) in early-onset group and 11 eyes (65%) in late-onset group ( P <0.001). CONCLUSIONS: Early and late-onset SWS glaucoma may represent 2 entities with different pathogenetic mechanisms, clinical presentations, primary surgical choices, and outcomes, though this needs corroboration in future studies.

PRCIS: In eyes with Sturge-Weber syndrome (SWS) with early onset glaucoma, primary combined trabeculotomy with trabeculectomy (CTT) had a good intermediate-term success rate and minimal postoperative complications. DESIGN: Retrospective cohort study. OBJECTIVE: To report the intermediate-term outcomes of primary CTT in early onset glaucoma with SWS. PATIENTS AND METHODS: This study included 49 eyes of 49 children (1997-2020) with SWS and early onset glaucoma who underwent primary CTT with at least 1-year postoperative follow-up. Success was defined as complete when intraocular pressure was >5 mm Hg and ≤16 mm Hg under general anesthesia or ≤21 mm Hg in the clinic without antiglaucoma medications (AGMs) and as qualified with AGM. RESULTS: The median age (interquartile range) at CTT was 0.58 (0.19, 8.3) years. The median postoperative follow-up was 4.7 years (2.5, 9). The majority were male children (31/49, 63%). Epilepsy was noted in 7 (14.3%) and diffuse choroidal hemangioma in 17 children (35%). At diagnosis, 37 eyes(75%), had corneal edema, and the mean (±SD) horizontal corneal diameter was 12.8 ± 0.7 mm. Postoperatively, the median intraocular pressure decreased from 26 (22, 30) mm Hg to 16 (12, 20) mm Hg ( P < 0.0001) and the median number of AGM reduced from 1 (0,1) to 0 (0,1; P < 0.01). Complete success probability of CTT was 86% (76, 96) at 1 year and 64% (49, 84) at 5 years. Qualified success was 98% (94, 100) at 1 year and 89% (78, 100) at 5 years. A larger cup-to-disk ratio ( P < 0.005) was associated with a higher risk of surgical failure. Postoperative complications were noted in 9 eyes (18%), all resolved with conservative management except one eye with a retinal detachment that ended in phthisis bulbi. CONCLUSION: CTT as a primary procedure showed good long-term efficacy and safety in SWS with early onset glaucoma.

OBJECTIVE: We aimed to evaluate determinants of functional outcome after pediatric hemispherotomy in a large and recent multicenter cohort. METHODS: We retrospectively investigated the functional outcomes of 455 children who underwent hemispherotomy at 5 epilepsy centers in 2000-2016. We identified determinants of unaided walking, voluntary grasping with the hemiplegic hand, and speaking through Bayesian multivariable regression modeling using missing data imputation. RESULTS: Seventy-five percent of children were seizure-free, and 44% stopped antiseizure medication at a 5.1-year mean follow-up (range = 1-17.1). Seventy-seven percent of children could walk unaided, 8% could grasp voluntarily, and 68% could speak at the last follow-up. Children were unlikely to walk when they had contralateral magnetic resonance imaging (MRI) abnormalities (40/73, p = 0.04), recurrent seizures following hemispherotomy (62/109, p = 0.04), and moderately (50/61, p = 0.03) or severely impaired (127/199, p = 0.001) postsurgical intellectual functioning, but were likely to walk when they were older at outcome determination (p = 0.01). Children were unlikely to grasp voluntarily with the hand contralateral to surgery when they had Rasmussen encephalitis (0/61, p = 0.001) or Sturge-Weber syndrome (0/32, p = 0.007). Children were unlikely to speak when they had contralateral MRI abnormalities (30/69, p = 0.002) and longer epilepsy duration (p = 0.01), but likely to speak when they had Sturge-Weber syndrome (29/35, p = 0.01), were older at surgery (p = 0.04), and were older at outcome determination (p < 0.001). INTERPRETATION: Etiology and bilaterality of structural brain abnormalities were key determinants of functional outcome after hemispherotomy. Longer epilepsy duration affected language outcomes. Not surprisingly, walking and talking ability increased with older age at outcome evaluation. ANN NEUROL 2024;95:377-387.

INTRODUCTION: A serous retinal detachment is one of the most likely ocular manifestation of Sturge-Weber syndrome (SWS). This finding can frequently occur as a complication after filtering surgery to maintain the intraocular pressure (IOP). Proper treatment has been approached with choroidal hemangioma as an organ target. To the best of our knowledge, various treatments for SRD are associated with diffuse choroidal hemangioma has been approached. However, a second retinal detachment following radiation therapy has worsened the situation. Here, we report an unexpected serous retina and choroidal detachment after non penetrating trabeculectomy. Although radiation therapy has been proposed for previous detachment to the ipsilateral eye in this case, repetition radiation therapy was not suggested concerning the health and quality of life especially in for young subjects. However, the kissing choroidal detachment in this case necessitated immediate intervention. Thus, posterior sclerectomy was performed for the recurrent retinal detachment. We believe that an intervention for a SWS case related complication will remain a significant and important to share as a public health contribution. CASE PRESENTATION: A 20 year-old male confirmed with SWS with no known family history was diagnosed with SWS. He was gain from another hospital for glaucoma therapy. On the left brain MRI showed severe hemiatrophy in the frontal and parietal lobes and leptomeningeal angioma. Although his right (RE) eye had 3 gonio surgeries, 2 Baerveldt tube shunts and Micropulse trans-scleral cyclophotocoagulation, his IOP remained uncontrollable when he was 20 years old. RE IOP was in controlled after non-penetrating filtering surgery hence, his RE developed a recurrent serous retinal detachment. A posterior sclerectomy was performed in 1 quadrant of the globe to drain subretinal fluid. CONCLUSION: Sclerectomies to the inferotemporal quadrant of the globe for serous retinal detachment associated with SWS are considered efficient for optimal drain subretinal fluid, resulting in complete regression of detachment.

INTRODUCTION: The aim of the study was to evaluate the efficacy and safety of combined trabeculotomy-non-penetrating deep sclerectomy (CTNS) in the treatment of Sturge-Weber syndrome (SWS) secondary glaucoma. METHODS: This retrospective study reviewed cases that underwent CTNS as initial surgery for SWS secondary glaucoma at our Ophthalmology Department center from April 2019 to August 2020. Surgical success was defined as an intraocular pressure (IOP) ≤ 21 mm Hg with (qualified success) or without (complete success) the use of anti-glaucoma medications. IOP >21 mm Hg or <5 mm Hg despite 3 or more applications of anti-glaucoma medications on 2 consecutive follow-up visits or at the last follow-up, performance of additional glaucoma (IOP-lowering) surgery, or with vision-threatening complications were classified as failure. RESULTS: A total of 22 eyes of 21 patients were included. Twenty-one eyes were of early-onset type and 1 eye was of adulthood onset. For Kaplan-Meier survival analysis, the overall success rates at 1st and 2nd years were 95.2% and 84.9%, while the complete success rates at 1st and 2nd years were 42.9% and 36.7%. At the last follow-up (22.3 ± 4.0 months, range: 11.2â¼31.2), overall success was achieved in 19 (85.7%) eyes and complete success in 12 (52.4%) eyes. Postoperative complications included transient hyphema (11/22, 50.0%) and transient â degree shallow anterior chamber (1/22, 4.5%), and retinal detachment (1/22, 4.5%). No other severe com plications were detected during the follow-up. CONCLUSION: CTNS significantly reduces IOP in SWS secondary glaucoma patients who have serious episcleral vascular malformation. CTNS in SWS secondary glaucoma patients is safe and effective for short and medium periods. A randomized controlled study comparing the long-term prognosis of SWS early-onset and late-onset glaucoma underwent CTNS is worth conducting.

BACKGROUND: Hemispherectomy is an optimal treatment for patients with Sturge-Weber syndrome (SWS) affecting the whole hemisphere; however, a consensus has not been reached regarding therapeutic choices for those with involvement of two to three lobes. In this study, we compared seizure and cognitive outcomes between medical and surgical treatment groups in patients with multilobar involvement. METHODS: We evaluated 50 patients with multilobar involvement. Surgical indications included (1) antiepileptic drug (AED)-resistant seizures; (2) developmental delay; and (3) cortical atrophy. Twenty-nine patients were classified in the medical treatment group (MTG), and 21 patients were in the surgical treatment group (STG). Seizure type and frequency, SWS electroencephalography score (SWS-EEGS), and pretherapeutic and posttherapeutic SWS neurological scores (SWS-NS) were compared between groups. Median ages at the initial evaluation of the MTG and STG were 4 and 2 years, and at the final evaluation were 13 and 17 years, respectively. RESULTS: The STG had a higher incidence (76.2%) of focal to bilateral tonic-clonic seizures and status epilepticus, although no difference in SWS-EEGS. Seizure and cognitive subcategories of SWS-NS at initial evaluation were worse in the STG (P = 0.025 and P = 0.007). The seizure subcategory in MTG and STG improved after therapy (P = 0.002 and P = 0.001). Cognition was maintained in MTG and improved in STG (P = 0.002). The seizure-free rates in MTG and STG were 58.6% and 85.7%, respectively. CONCLUSIONS: Appropriate therapeutic choices improved seizure outcomes. Although patients who required surgery had more severe epilepsy and cognitive impairment, surgery improved both.

BACKGROUND: A subpopulation of patients with Sturge-Weber syndrome (SWS) develop medically intractable epilepsy. There is a paucity of literature on preoperative factors that predict postoperative seizure outcomes in these patients. An individual participant data meta-analysis (IPDMA) was performed to discern preoperative variables associated with favorable seizure outcomes in pediatric SWS patients undergoing epilepsy surgery. METHODS: PubMed, Cochrane, Web of Science, and Scopus were independently queried following PRISMA guidelines. Studies that reported seizure outcomes in individual pediatric SWS patients were selected. Preoperative demographic variables and disease characteristics were recorded and evaluated in a time-to-event fashion via Cox regression and Kaplan-Meier analysis with log-rank test. RESULTS: A total of 18 studies with 108 patients were included for meta-analysis. Median age at seizure onset was 4.5 months, and 85 patients (78.7%) were seizure-free at last follow-up (median: 72 months). On multivariable Cox regression, no variables were independent predictors of post-operative seizure freedom duration, including the extent of hemispheric resection. There were also no differences in time-to-seizure recurrence on Kaplan-Meier analysis when comparing those treated with hemispheric surgery and those with less than hemispheric surgery (p = 0.52). CONCLUSION: This IPDMA showed that both resective and hemispheric epilepsy surgery achieve favorable and comparable seizure outcomes in pediatric SWS patients. The best available evidence using IPD suggests that resective surgery may be an appropriate alternative to hemispheric epilepsy surgery in well-selected patients. Prospective multi-institutional studies with greater follow-up are warranted to further investigate predictors of seizure outcome in pediatric SWS patients.

PURPOSE: To evaluate mid-term efficacy and safety of ab externo Microcatheter-assisted trabeculotomy (MAT) for early-onset glaucoma associated with Sturge-Weber syndrome (SWS) and phakomatosis pigmentovascularis (PPV). DESIGN: Retrospective, non-comparative, interventional case series. METHODS: Medical records of consecutive SWS- or PPV-associated glaucoma patients who had undergone ab externo MAT between August 2017 and April 2020 at Beijing Children's Hospital were reviewed. Success was defined as an intraocular pressure (IOP) of <21 mmHg with (qualified success) or without (complete success) the use of antiglaucoma medication. RESULTS: Overall, 13 eyes (12 patients) with SWS and 9 eyes (8 patients) with PPV were included, with a mean age of 12.8 ± 15.8 months at the time of surgery and a mean follow-up time of 39.5 ±10.4 months. Both the SWS (26.5 ± 5.3 mmHg at baseline vs 16.5 ± 5.0 mmHg at the last visit; P < .001) and PPV (29.2 ± 7.5 mmHg vs 23.4 ± 4.7 mmHg; P = .014) subsets achieved a statistically significant fall in IOP following surgery. The Kaplan-Meier survival rate of complete (qualified) success after 42 months was 76.2% (87.5%) and 22.2% (40.0%) for eyes with SWS and PPV, respectively. Complications were minimal. Phakomatosis pigmentovascularis was associated with worse surgical outcomes. CONCLUSIONS: Ab externo MAT is an effective and safe treatment for early-onset glaucoma associated with SWS, but a gradual increase in IOP over time was noted in some patients. Ab externo MAT has limited efficacy for early-onset glaucoma associated with PPV in the mid-term.

Parkes-Weber syndrome (PWS) is a rare congenital vascular syndrome consisting of capillary, venous, lymphatic, and arteriovenous malformation. There are many complications of PWS, such as ulceration, bleeding, infection, and cardiac failure. Among them, skin ulceration is one of the thorniest problems in PWS, requiring multidisciplinary approaches for the management. In this article, we presented the case of an elderly patient with refractory ulceration who received numerous treatments with no effect and finally underwent a major amputation to improve the quality of life. Moreover, we reviewed 23 previously reported cases to improve our understanding of the management for PWS patients with ulceration.

OBJECTIVE: Sturge-Weber syndrome (SWS) is a rare neurocutaneous disorder presenting mostly with a facial port-wine stain and leptomeningeal angiomatosis. More than 85% of the patients are affected by epilepsy by the age of 2 years. Seizure and symptom control is the focus of SWS treatment, since no causal therapy exists yet. For pharmacologically intractable epilepsy, surgery is a treatment option. The aim of this systematic review and meta-analysis was to provide an overview of the literature regarding lesionectomy in SWS with a focus on seizure outcome, complications, and motor and cognitive development. METHODS: The PubMed and Embase databases were searched using a systematic search strategy to identify studies on SWS from their inception until 2021. Two independent researchers assessed the studies for inclusion and quality. Outcome measures were seizure outcome, postoperative complications, and motor and cognitive development. Thereafter, a systematic review was conducted, and a meta-analysis was performed for all included cohort studies. Risk of bias was assessed using the Newcastle-Ottawa Scale. Forest plots have been generated for all outcomes; risk ratio was used for pooled outcomes. A p value < 0.05 was considered as statistically significant. RESULTS: After removal of duplicates, the authors screened 439 articles, of which 9 articles with 150 patients were included. Our case and 5 case reports and 4 retrospective cohort studies were included for systematic review. The latter 4 studies qualified for the meta-analysis. In these 4 articles, 144 patients received surgical treatment: 81 (56%) underwent focal lesionectomy and 63 (44%) hemispherectomy. Pooled outcome analysis for postoperative favorable seizure outcome showed a nonsignificant difference between lesionectomy and hemispherectomy (69.2% vs 87.3%; RR 0.73, 95% CI 0.50-1.08; t = -2.56, p = 0.08). Lesionectomy showed a significantly lower rate for developmental delay and postoperative hemiparesis in comparison with hemispherectomy (29.8% vs 76.3%; RR 0.41, 95% CI 0.28-0.59; z = -4.77, p < 0.0001 and 18.1% vs 100%; RR 0.11, 95% CI 0.06-0.21; z = -6.58, p < 0.0001, respectively). CONCLUSIONS: Based on the limited literature available, lesionectomy leads to a nonsignificant lower seizure control rate, while postoperative developmental or motor deficits are significantly lower compared with hemispherectomy. Therefore, focal lesionectomy remains a valid alternative to hemispherectomy in SWS with a clearly localized epileptogenic area; however, individual case-based decisions in a specialized multidisciplinary team are of paramount importance.

This study was aimed to evaluate the clinical efficacy of hemangioma resection in the treatment of infantile encephalofacial angiomatosis (Sturge-Weber syndrome, SWS) through magnetic resonance imaging (MRI) images, and intelligent algorithms were employed to process MRI images. A retrospective study of 45 children diagnosed with facial hemangioma admitted to hospital was conducted. Then, MRS images were acquired, and a mathematical model for MRI image denoising and reconstruction was constructed based on nonlocal similar block low-rank prior algorithms. The processing effect was assessed regarding the peak signal-to-noise ratio (PSNR) and structural similarity (SSIM). Finally, MRI images were collected to analyze the difference between the metabolites of N-acetylaspartic acid (NAA), creatine (Cr), choline (Cho), and their ratios in the lesions of the children before and after treatment. The improvement rate was analyzed through a twelve-month follow-up. The algorithm test results showed that compared with the classic K-singular value decomposition (K-SVD) denoising algorithm and the Sparse MRI reconstruction algorithm, the proposed algorithm processed MRI images more clearly and had more detailed information. The quantitative results showed that the PSNR and SSIM in the image processed by the algorithm proposed were remarkably large. The clinical treatment results showed that compared with those before treatment, the nCho level after treatment, the ratio of Cho/Cr and Cho/NAA were remarkably reduced, and the difference was remarkable (P < 0.05). The follow-up results showed that the considerable improvement rate was 88.89%, the postoperative organ remodeling rate was 17.78%, and the probability of reoperation was only 6.67%. In summary, the introduction of intelligent algorithms for denoising and reconstruction of MRI images can remarkably improve image quality and help doctors use image information to diagnose diseases and evaluate treatment effects. The hemangioma resection for the treatment of pediatric SWS had a high treatment improvement rate and was worthy of clinical adoption.

PURPOSE: To report the outcomes of trans-scleral cyclophotocoagulation (TSCPC) in pediatric glaucoma secondary to Sturge-Weber syndrome (SWS). METHODS: The medical records of all SWS glaucoma cases in the pediatric age group (<18 years of age) that underwent TSCPC at our institute from January 2000 to September 2017. RESULTS: A total of 22 eyes of 22 patients were included. Mean age at the time of TSCPC was 5.9 ± 5 years (range, 0-16 years). Mean postoperative follow-up was 32.2 ± 16.6 months (range, 6-54 months). Intraocular pressure (IOP) was reduced from a preoperative mean of 28 ± 4.5 mm Hg to 20.3 ± 3.7 mm Hg at 36 months (P = 0.02). The mean number of glaucoma medications used was 3.5 ± 0.7 preoperatively and 3.1 ± 1.4 at 36 months (P = 0.70). The overall success rate (complete and qualified) was 72.7% at 12 months, 62.3% at 24 months, and 54.5% at 36 months. One eye developed hypotony and choroidal effusion, which resolved with medical therapy. Of the patients for whom visual acuity was recorded preoperatively, no one experienced a loss of more than 2 lines of Snellen visual acuity. CONCLUSIONS: In our study cohort, TSCPC resulted in mild reduction in IOP, with minimal complications.

Few studies have reported the clinical presentation, surgical treatment, outcomes and influential factors for patients with epilepsy and Sturge-Weber syndrome. This large-scale retrospective study continuously enrolled 132 patients with Sturge-Weber syndrome and epilepsy from January 2008 to December 2018 at our hospital to analyse their characteristics. Among these patients, 90 underwent epilepsy surgery, and their postoperative 2-year follow-up seizure, cognitive and motor functional outcomes were assessed and analysed. Univariable and multivariable logistic analyses were conducted to explore the influential factors. Among the patients with Sturge-Weber syndrome for whom characteristics were analysed (n = 132), 76.52% of patients had their first epileptic seizures within their first year of life. The risk factors for cognitive decline were seizure history ≥ 2 years [adjusted odds ratio (aOR) = 3.829, 95% confidence interval (CI): 1.810-9.021, P = 0.008)], bilateral leptomeningeal angiomas (aOR = 3.173, 95% CI: 1.970-48.194, P = 0.013), age at onset <1 year (aOR = 2.903, 95% CI: 1.230-6.514, P = 0.013), brain calcification (aOR = 2.375, 95% CI: 1.396-5.201, P = 0.021) and left leptomeningeal angiomas (aOR = 2.228, 95% CI: 1.351-32.571, P = 0.030). Of the patients who underwent epilepsy surgery (n = 90), 44 were subject to focal resection, and 46 underwent hemisphere surgery (19 anatomical hemispherectomies and 27 modified hemispherotomies). A postoperative seizure-free status, favourable cognitive outcomes, and favourable motor outcomes were achieved in 83.33%, 44.44% and 43.33% of surgical patients, respectively. The modified hemispherotomy group had similar surgical outcomes, less intraoperative blood loss and shorter postoperative hospital stays than the anatomical hemispherectomy group. Regarding seizure outcomes, full resection (aOR = 11.115, 95% CI: 1.260-98.067, P = 0.020) and age at surgery < 2 years (aOR = 6.040, 95% CI: 1.444-73.367, P = 0.031) were positive influential factors for focal resection. Age at surgery < 2 years (aOR = 15.053, 95% CI: 1.050-215.899, P = 0.036) and infrequent seizures (aOR = 8.426, 95% CI: 1.086-87.442, P = 0.042; monthly versus weekly) were positive influential factors for hemisphere surgery. In conclusion, epilepsy surgery resulted in a good postoperative seizure-free rate and favourable cognitive and motor functional outcomes and showed acceptable safety for patients with epilepsy and Sturge-Weber syndrome. Modified hemispherotomy is a less invasive and safer type of hemisphere surgery than traditional anatomic hemispherectomy with similar surgical outcomes. Early surgery may be helpful to achieve better seizure outcomes and cognitive protection, while the risk of surgery for young children should also be considered.

BACKGROUND: Parkes Weber syndrome (PWS) is a rare and congenital vascular malformation manifesting as hemihypertrophy of the extremities, cutaneous hemangiomas, varicose veins, and arteriovenous fistula of the affected limbs. The incidence rate of spinal arteriovenous fistula (AVF) associated with PWS is extremely rare. CASE PRESENTATION: We reported a case of an adolescent girl with PWS who presented with a rupture spinal perimedullary AVF at the level of T12-L1. She was successfully treated with emergent surgical decompression and subsequent endovascular embolization. The clinical features and treatment of spinal AVF associated with PWS were discussed and a brief literature review was presented. CONCLUSION: Based on this case report, we suggested that the management of spinal AVF in PWS should also be individualized and be tailored according to the condition and expectation of the patients as well as the angioarchitecture of the vascular malformation.

ABSTRACT: Surgical management of odontogenic infections in Sturge-Weber Syndrome is challenging, due to the risk of massive bleeding and difficulty to achieve hemostasis. The authors describe the use of preoperative vascular embolization for oral surgery in a 29-year-old patient. The authors highlight the importance of hemostatic agents and primary wound closure and the role of vascular embolization as a potential tool for preventing hemorrhage in these cases.

BACKGROUND: Individuals with Sturge-Weber syndrome (SWS) often expereince intractable epilepsy and cognitive decline. We hypothesized that the extent of the leptomeningeal capillary malformation (LCM) may correlate with the severity of neurological impairment due to SWS. We tested the hypothesis in a cross-sectional study of seizure severity and electroencephalographic (EEG) findings and a retrospective cohort study for surgical indications related to the extent of the LCM. METHODS: We enrolled 112 patients and classified them according to LCM distribution: (1) bilateral, (2) hemispheric, (3) multilobar, and (4) single lobe. Age at seizure onset, seizure semiology and frequency, and EEG findings were compared. Surgical indications were evaluated for each group by Fisher exact test, and predictors for surgery were evaluated by univariate and multivariate analyses. Therapeutic efficacy was evaluated by the SWS-Neurological Score (SWS-NS). RESULTS: The bilateral and hemispheric groups had early seizure onset (4.0 months old and 3.0 months old), frequent seizures (88.9% and 80.6% had more than one per month), focal-to-bilateral tonic-clonic seizures (88.9% and 74.2%), and status epilepticus (100% and 87.1%). The groups' EEG findings did not differ substantially. Surgical indications were present in 77.8% of the bilateral, 88.1% of the hemispheric, and 46.8% of the multilobar groups. Seizure more than once per month was a predictor of surgical treatment. Seizure subscore improved postoperatively in the hemispheric and multilobar groups. Even after surgical treatment, the bilateral and hemispheric groups exhibited higher SWS-NSs than members of the other groups. CONCLUSION: Our study demonstrated a strong association between extensive LCM and epilepsy severity. Surgical intervention improved seizure outcome in patients with SWS with large LCMs.

AIMS: To compare the surgical outcomes of trabeculectomy versus Ahmed glaucoma valve (AGV) implantation in the surgical management of glaucoma in patients with Sturge-Weber syndrome (SWS). METHODS: A retrospective chart review was performed on 40 eyes of secondary glaucoma in patients with SWS separated into two groups: AGV (N=20) and trabeculectomy with mitomycin C (N=20). Demographic data, intraocular pressure (IOP), visual acuity and the number anti-glaucoma medications (AGM) needed were evaluated prior to and following surgery. Surgical success was defined as an IOP of ≤21 mm Hg, with or without the use of topical AGM. Complete success was achieved when IOP values were obtained without AGM. RESULTS: Mean follow-up duration was 23.15±2.36 months and 22.95±2.87 months in the AGV and trabeculectomy groups, respectively (p=0.811). Both the AGV (34.50±4.65 mm Hg at baseline to 15.20±3.31 mm Hg at last visit) and trabeculectomy (32.10±5.86 mm Hg to 16.10±3.02 mm Hg) groups achieved a statistically significant fall in IOP following surgery (p=0.000). Kaplan-Meier survival of complete success after 24 months was 80% and 70% after AGV implant and trabeculectomy, respectively, but the difference between two groups was not statistically significant (p=0.442). CONCLUSIONS: Both AGV implant and trabeculectomy appear to be safe and efficacious in controlling glaucoma secondary to SWS, although the potential for serious complications such as choroidal detachment must be anticipated when planning surgeries in patient with SWS, and the authors recommend the maintenance of a stable IOP during and following the surgery to avoid such complications.

PURPOSE: Sturge-Weber syndrome (SWS) is a neurocutaneous facomatosis characterized by facial and leptomeningeal angioma, glaucoma, seizures, and neurological disability. Therefore, a challenging multidisciplinary interaction is required for its management. The goal of this paper is to review the main aspects of SWS and to present an illustrative pediatric series. METHODS: The pertinent literature has been analyzed, focused mainly on etiopathogenesis, pathology, clinical features, diagnostic tools, management, and outcome of the disease. Moreover, a series of 11 children operated on for refractory epilepsy between 2005 and 2015 (minimum follow-up 5 years, mean follow-up 9.6 years) is reported. The series consists of six boys and five girls with 6.5-month and 16.2-month mean age at seizure onset and at surgery, respectively. Seizures affected all children, followed by hemiparesis and psychomotor delay (81%), glaucoma (54%), and other neurological deficits (45%). RESULTS: All children underwent hemispherectomy (anatomical in three cases, functional in two cases, hemispherotomy in six cases); one patient needed a redo hemispherotomy. Mortality was nil; disseminated intravascular coagulation and interstitial pneumonia occurred in one patient each; three children had subdural fluid collection. Eight patients (72%) are in the ILAE Class 1 (completely seizure and aura free), two in Class 2 (only auras, no seizure), and one in Class 3 (1-3 seizure days per year). AEDs discontinuation was possible in 73% of cases. The most important news from the literature concerned the pathogenesis (role of the mutation of the GNAQ gene in the abnormal SWS vasculogenesis), the clinical findings (the features and pathogenesis of the stroke-like episodes are being understood), the diagnostic tools (quantitative MRI and EEG), and both the medical (migraine, seizures) and surgical management (epilepsy). The epileptic outcome of SWS patients is very good (80% are seizure-free), if compared with other hemispheric syndromes. The quality of life is affected by the neurological and cognitive deficits. CONCLUSIONS: SWS still is an etiological and clinical challenge. However, the improvements over the time are consistent. In particular, the neurosurgical treatment of refractory epilepsy provides very good results as long as the indication to treatment is correct.
