Abstract
BACKGROUND Hydrocephalus frequently occurs with midline posterior fossa cystic collections. The classification of this heterogeneous group of developmental anomalies, including Dandy-Walker malformation, persisting Blake's pouch, retrocerebellar arachnoid cysts, and mega cisterna magna, is subject of debate. The absence of diagnostic criteria is confusing regarding the ideal management of PFCC-related hydrocephalus. OBJECTIVE To decipher the surgical strategy for the treatment of children with PFCC-related hydrocephalus through a retrospective analysis of the surgical outcome driven by their clinical and radiological presentation. METHODS This study enrolled patients operated of symptomatic PFCC-related hydrocephalus. Clinical and MRI features were examined, as well as the surgical outcome. Unbiased subgroup classification of the patients was performed with multiple component analysis as a function of imaging characteristics and hierarchical clustering on principal component. Outcome was assessed with binomial logistic regression and Kaplan-Meier analysis. RESULTS Fifty-four patients were included between 2007 and 2021. Multiple component analysis suggested that cerebellar and vermian hypoplasia, vermian rotation, basal-tentorial angle, and fastigial angle were strongly correlated. Hierarchical clustering and the distribution of the patients in the bidimensional plot showed the clear segregation of 3 major clusters, which correlated with the radiological diagnosis ( P < .01). Binomial logistic regression and survival analysis showed that endoscopic third ventriculostomy was an effective treatment for patients with persisting Blake's pouch, while failing to control hydrocephalus in most of patients with Dandy-Walker malformation. CONCLUSION Preoperative MRI in patients with PFCC-related hydrocephalus is essential to better define the diagnosis. The choice of treatment strategy notably relies on correct radiological diagnosis.

Abstract
INTRODUCTION Dandy-Walker complex and pleomorphic xanthoastrocytomas are both rare disease entities that typically manifest early in life and are associated with congenital etiological factors. Dandy-Walker complex is a cerebellar malformation associated with a series of anatomical changes. The disease onset is usually at birth or during infancy. Late onset in adulthood is uncommon. Pleomorphic xanthoastrocytoma is a rare WHO grade II astrocytic tumor affecting mainly young adults. Concomitant occurrence of Dandy-Walker complex and pleomorphic xanthoastrocytoma has not been previously reported. PATIENT CONCERNS AND DIAGNOSIS A 30-year-old woman with a previous history of unconfirmed resected lateral ventricle meningioma presented with severe headache for 1 day. Imaging examination revealed a mass in the right lateral ventricle with heterogeneous signal patterns, changes in the posterior fossa corresponding to a Dandy-Walker variant, and mild hydrocephalus. INTERVENTIONS AND OUTCOMES Surgical complete resection of the mass was achieved. postoperative histopathological examination confirmed WHO grade II pleomorphic xanthoastrocytoma. Three years postsurgery, ventriculoperitoneal shunt was performed due to worsening of hydrocephalus. The patient has since remained symptom-free. CONCLUSION This is the first report of concomitant occurrence of Dandy-Walker complex and pleomorphic xanthoastrocytoma. The association of neurological congenital malformation with intracranial neoplasms may be multifactorial, with underlying role of genetic mutations or chromosome alterations.

Abstract
Dandy-Walker syndrome (DWS) is characterized by perfect or partial defect of the cerebellum vermis and cystic dilatation of the posterior fossa communicating with the fourth ventricle. Common clinical signs are mental retardation, cerebellar ataxia, and those of increased intracranial pressure (ICP). Associated congenital anomalies are craniofacial, cardiac, renal, and skeletal abnormalities. We experienced a case of intravenous sedation and six times of "the same day" general anesthesia for a school-aged boy (10-13 years old) with DWS and hypodentinogenesis. The patient underwent an examination and dental treatments. We had to pay attention to airway management tracheal tube selection and control of ICP. In addition, we should prevent tooth injuries through mishaps during tracheal intubations, since all-tooth-hypoplasia with fragile dental crowns was strongly suggested in this case. Detailed postoperative care is also required for general anesthesia afflicted with DWS.

Abstract
Perioperative management of a patient with Dandy-Walker malformation (DWM) with tetralogy of Fallot (TOF), patent ductus arteriosus, and pulmonary artery stenosis is a great challenge to the anesthesiologist. Anesthetic management in such patients can trigger tet spells that might rapidly increase intracranial pressure (ICP), conning and even death. The increase in ICP can precipitate tet spells and further brain hypoxia. To avoid an increase in ICP during TOF corrective surgery ventriculo-peritoneal (VP) shunt should be performed before cardiac surgery. We present the first case report of a 11-month-old male baby afflicted with DWM and TOF who underwent successful TOF total corrective surgery and fresh autologous pericardial pulmonary valve conduit implantation under cardiopulmonary bypass after 1 week of VP shunt insertion.

Abstract
Congenital malformations of the central nervous system are related to alterations in neural tube formation, including most of the neurosurgical management entities, dysraphism and craniosynostosis; alterations of neuronal proliferation; megalencefaly and microcephaly; abnormal neuronal migration, lissencephaly, pachygyria, schizencephaly, agenesis of the corpus callosum, heterotopia and cortical dysplasia, spinal malformations and spinal dysraphism. We expose the classification of different central nervous system malformations that can be corrected by surgery in the shortest possible time and involving genesis mechanisms of these injuries getting better studied from neurogenic and neuroembryological fields, this involves connecting innovative knowledge areas where alteration mechanisms in dorsal induction (neural tube) and ventral induction (telencephalization) with the current way of correction, as well as the anomalies of cell proliferation and differentiation of neuronal migration and finally the complex malformations affecting the posterior fossa and current possibilities of correcting them.

Abstract
INTRODUCTION Dandy-Walker Syndrome (DWS) is a constellation of congenital anomalies of the central nervous system consisting of cerebellar vermis hypoplasia or agenesis, cystic dilatation of the fourth ventricle, enlarged posterior fossa, and a high tentorium. Hydrocephalus is a common occurrence in DWS and its treatment varies between shunting-ventriculoperitoneal or cystoperitoneal or both, endoscopic cyst fenestration, and third ventriculostomy. Chronic cerebral herniation is a known complication of treatment in DWS; however, we present an unusual case of central brain herniation. CASE REPORT A 2 year old boy with shunted DWS presented with status epilepticus. Initial CT brain scan showed no increase in ventricle or cyst size; however, tapping the shunt reservoir did not yield any CSF prompting a shunt revision. Postoperatively, he was very slow to wake and subsequently experienced an episode of fixed pupils and extensor posturing. MRI brain demonstrated severe herniation of both thalami through the tentorium. CONCLUSION This child had chronic central brain herniation (CCBH) secondary to the shunting of his cyst. To our knowledge, this is the first case of CCBH following treatment of DW cyst.

Abstract
INTRODUCTION Even if the first description of Dandy-Walker dates back 1887, difficulty in the establishment of correct diagnosis, especially concerning differential diagnosis with other types of posterior fossa CSF collection, still persists. Further confusion is added by the inclusion, in some classification, of different malformations with different prognosis and therapeutic strategy under the same label of "Dandy-Walker". METHODS An extensive literature review concerning embryologic, etiologic, pathogenetic, clinical and neuroradiological aspects has been performed. Therapeutic options, prognosis and intellectual outcome are also reviewed. CONCLUSION The correct interpretation of the modern neuroradiologic techniques, including CSF flow MR imaging, may help in identifying a "real" Dandy-Walker malformation. Among therapeutical strategies, single shunting (ventriculo-peritoneal or cyst-peritoneal shunts) appears effective in the control of both ventricle and cyst size. Endoscopic third ventriculostomy may be considered an acceptable alternative, especially in older children, with the aim to reduce the shunt-related problems. Prognosis and intellectual outcome mostly depend on the presence of associated malformations, the degree of vermian malformation and the adequate control of hydrocephalus.

Abstract
PURPOSE Obstruction of the CSF circulation distal to the fourth ventricle is a rare cause of noncommunicating hydrocephalus. Endoscopic third ventriculostomy (ETV) represents one of the treatment options, but reports of results are rare. METHODS Between March 1997 and June 2008, 20 ETVs in 20 patients (mean 32.4 years, range 1 month-79 years) for noncommunicating hydrocephalus distal to the fourth ventricle were undertaken. All patients suffered from severe internal hydrocephalus and typical clinical symptoms. In addition to the standard ETV, a transaqueductal inspection of the posterior fossa with a flexible scope was performed. All patients were prospectively followed. RESULTS An ETV was achieved in all patients. It was clinically successful in 15 of 20 patients (75%) with an improvement of 50% (three out of six) of the pediatric and of 83% (12 out of 14) of the adult population. A reduction of ventricle size was found in ten (50%). Five patients (25%) received ventriculoperitoneal shunting. A transaqueductal inspection of the posterior fossa cerebrospinal fluid (CSF) pathways was performed in 16. In the remaining four patients, no inspection with the flexible scope was done. One clinically silent fornix contusion and one CSF fistula which was treated conservatively occurred. There was no permanent morbidity. CONCLUSIONS ETV is a successful treatment option in CSF pathway obstructions distal to the fourth ventricle. Although the success rate particularly of the pediatric population appears to be lower than with other indications of obstructive hydrocephalus, a relevant part of the patient population improves after ventriculostomy and shunting can be avoided.

Abstract
Three cases of Dandy-Walker syndrome associated with congenital heart defects are reported, and their management is described. The various theories concerning the aetiology of the Dandy-Walker syndrome are discussed and it is suggested that the theory of primary developmental atresia of the foramina of Magendie and Luschka is still acceptable. If the child with Dandy-Walker syndrome requires treatment by extracranial CSF drainage it is proposed that a ventriculo-peritoneal shunt is preferable when there is any suspicion of cardiac anomaly. The proximal catheter should be placed in the posterior fossa cyst (dilated fourth ventricle) rather than in the lateral ventricle.

Abstract
OBJECT The aim of this study was to assess the efficacy of various treatment options available for children with Dandy-Walker malformation (DWM) and to evaluate the role of endoscopic procedures in the treatment of this disorder. METHODS The authors conducted a retrospective review of 72 children who underwent surgical treatment for DWM during a 16-year period. All patients underwent computed tomography scanning, and 26 underwent magnetic resonance (MR) imaging. The initial surgical treatment included ventriculoperitoneal (VP) shunt placement in 21 patients, cystoperitoneal (CP) shunt placement in 24, and combined VP and CP shunt insertion in three. Twenty-one patients underwent endoscopic procedures (endoscopic third ventriculostomy [ETV] alone in 16 patients, ETV with aqueductal stent placement in three, and ETV with fenestration of the occluding membrane in two). Three patients underwent membrane excision via a posterior fossa craniectomy. In the 26 patients who had undergone preoperative MR imaging, aqueductal patency was noted in 23 and aqueductal obstruction in three. These three patients underwent placement of a stent from the third ventricle to the posterior fossa cyst in addition to the ETV procedure. During the follow-up period, 12 patients with a CP shunt and four with a VP shunt experienced shunt malfunctions that required revision. Four patients with a CP shunt also required placement of a VP shunt. In addition, five of the 21 ETVs failed, requiring VP shunt insertion. A reduction in ventricle size noted on postoperative images occurred more frequently in patients with a VP shunt, whereas a reduction in cyst size was more appreciable in patients with a CP shunt. Successful ETV resulted in a slight decrease in ventricle size and varying degrees of reduction in cyst size. CONCLUSIONS Endoscopic procedures may be considered an acceptable alternative in children with DWM. The authors propose a treatment protocol based on preoperative MR imaging findings of associated aqueductal stenosis.

Abstract
We present our experience with the treatment of 13 patients with Dandy-Walker syndrome. The common presenting symptom and associated central nervous system anomaly were enlargement of head and occipital encephalocele, respectively. Eleven out of 13 patients were treated surgically after stabilization of systemic medical status. Two patients could not be operated because of poor medical condition. In 6 patients with an opened passage between posterior fossa cyst and lateral ventricle, cystoperitoneal shunt system with medium pressure valve was the treatment of choice. In 5 patients with no relation between cyst and ventricle, cystoperitoneal and ventriculoperitoneal shunting with 'Y' connectors were applied separately. Another patient with a shunt infection was treated by shunt system renewal combined with parenteral antibiotics. One patient died 7 months after the operation due to recurrent meningitis.

Abstract
Blockage of a ventriculoperitoneal (VP) shunt is very common. Here, we describe an unusual case of shunt blockage in an infant. He was shunted for hydrocephalus associated with a Dandy-Walker malformation diagnosed at birth. At surgery, the entire VP shunt was found to have migrated into the subgaleal space, which clinically presented as shunt obstruction. We suggest techniques to avoid this rare, but preventable, complication of shunt surgery.

Abstract
OBJECTIVE Shunting of the lateral ventricle and the posterior fossa cyst is the advocated surgical therapy for children with Dandy-Walker malformation (DWM) and associated aqueductal obstruction. The high rate of complications of combined shunting stimulated the authors to search for an alternative surgical solution. CLINICAL PRESENTATION/INTERVENTION After transtentorial endoscopic ventriculocystostomy, a cystoventricular catheter, connected to a peritoneal shunt, was placed in a neonate with DWM and associated aqueductal obstruction. Immediately prior to ventriculocystostomy, the presence of a blocked third ventricular outflow was reconfirmed by contrast medium injection. Neuronavigation was required to define the surgical path from the lateral ventricle through the tentorium and the overlying small rim of brain parenchyma into the posterior fossa cyst. The postoperative clinical course was uneventful with radiologically proven reduction of the size of the ventricular system and the cyst. CONCLUSION Cystoventriculoperitoneal shunt placement after transtentorial endoscopic ventriculostomy is a surgical alternative in very young children with DWM and associated aqueductal obstruction.

Abstract
OBJECTIVE AND IMPORTANCE Dandy-Walker malformation has conventionally been managed with placement of cystoperitoneal or ventriculoperitoneal shunts. However, associated aqueductal obstruction requires simultaneous drainage of both the supratentorial and infratentorial compartments. CLINICAL PRESENTATION Three children with Dandy-Walker malformation and aqueductal obstruction were managed with endoscopic third ventriculostomy and placement of a stent from the third ventricle to the posterior fossa cyst. INTERVENTION After an endoscopic third ventriculostomy was performed, the stent was placed from the third ventricle to the posterior fossa cyst through the thinnest part of the posteroinferior wall of the aqueduct. There was no operative morbidity. In one patient, the stent was malpositioned, requiring a repositioning. The endoscopic third ventriculostomy was successful in two patients, whereas it failed in one, requiring a ventriculoperitoneal shunt placement. CONCLUSION Cystoventricular stent placement with endoscopic third ventriculostomy is a promising alternative in patients with Dandy-Walker malformation with aqueductal obstruction.

Abstract
BACKGROUND The Dandy-Walker Syndrome (DWS) is a congenital malformation of the structures of the posterior cranial fossa with failure of the Luschka and Magendie foramina, which connect the ventricular system to the subarachnoid space, to open. In this syndrome, the cerebellar vermis may be absent or hypoplastic, the hemispheres small, the encephalic trunk and cervical spinal bone marrow flattened, complete or partial absence of cerebellar vermis, cystic dilatation of IV ventricle and frequently hydrocephalus. METHODS We evaluated 56 cases of fetal malformations of the central nervous system from January 1998 to May 2001. Of these 56, 11 regarded the Dandy-Walker Syndrome. Ultrasound examinations were carried out at the 9(th) and 10(th) weeks, at the 21(st)-23(rd) weeks and at the 31(st) to 34(th) weeks of gestation so as to assess foetal anatomy and morphology. RESULTS The results of the 11 pregnancies with Dandy-Walker Syndrome were as follows: 3 spontaneous miscarriages (at the 15(th), 18(th) and 20(th) weeks of gestation), 5 therapeutic abortions, 3 term pregnancies. Of the 3 newborns we were only able to follow the clinical course of two of them; both newborns underwent an intervention for ventriculo-peritoneal fluid derivation. At the moment both babies, aged respectively 30 and 25 months, are in good physical, intellectual and behavioural condition. CONCLUSIONS Bearing in mind the notable clinical and socioeconomic importance of this malformation, we consider foetal morphological ultrasound to be a valid instrument for the correct management of pregnancy. Identification of lesions makes use of the comparison of ultrasound data with the results of histopathological examinations.

Abstract
A 3-month-old female infant with Dandy-Walker malformation manifesting as hydrocephalus was treated successfully by only ventriculoperitoneal shunting. A flexible neuroendoscope was used intraoperatively to confirm the patency of the aqueduct, i.e. communication of the ventricular system and the cyst in the posterior fossa. Direct confirmation of the patency of the aqueduct and cyst communication is valuable to select the shunt procedure in the treatment of Dandy-Walker malformation.

Abstract
OBJECTIVE The goal of this study is to evaluate the indications, benefit and complications of shunts and endoscopic fenestrations in the treatment of malformative intracranial cysts. MATERIAL AND METHOD The records of 172 consecutive children (mean age of 4 years) were reviewed. All had a malformative cyst. Dandy Walker malformation, mega cisterna magna, and cysts from tumoral or porencephalic origin were excluded from the study. The cysts were diagnosed either in utero (n=64) or postnatally (n=108). Most of them were unique (94.8%) and localized in the posterior fossa (26.2%) or at the convexity (23.2%). Indication for surgery was based on clinical symptoms (n=101; 86.3%) or size of the lesion (n=16; 13.7%). Endoscopy was the treatment of choice when cysts were in closed relationship with enlarged ventricles. Shunting procedures were indicated when endoscopy was not feasible and craniotomies when shunt insertion was unsafe or diagnosis uncertain. Fifty children underwent an endoscopic fenestration, 55 a shunting procedure, 7 the puncture or the external drainage of a pericerebral collection and 5 a direct surgical approach. The mean follow-up was 5.5 years. Psycho-motor, intellectual and school performances were evaluated in 93 children (54%). Success was defined by both the disappearance of symptoms of increased intra cranial pressure and regression of the cyst. RESULTS Compared to shunts, endoscopic fenestrations were more frequently successful (70% vs 61.8%), led to less complications (6% vs 61.8%) and to a lesser number of reoperations (in average 1.6 operation per child vs 2.2). Median developmental and intellectual quotients for the whole series were respectively 98 and 97 and did not depend upon the type of treatment. CONCLUSION The study of this series shows that treatment modalities necessarily vary according to the site of the cysts but that endoscopic fenestrations are preferable to shunts whenever feasible.

Abstract
OBJECTIVE AND IMPORTANCE Syringomyelia in association with the Dandy-Walker complex is rare and only 17 cases have been reported, mostly as autopsy findings or incidental reports in series for other conditions. We present a further case report and discuss the possible pathogenetic mechanisms of syrinx formation in the presence of the Dandy-Walker complex. We emphasize the role of foramen magnum obstruction and alteration in cerebrospinal fluid flow dynamics in syrinx formation. The therapeutic importance of disimpaction of the foramen magnum is stressed. CLINICAL PRESENTATION A 39-year-old man presented with headache. As a child, he had had cystoperitoneal and ventriculoperitoneal shunts inserted for hydrocephalus in association with the Dandy-Walker complex. On examination, the patient had limited upgaze but was otherwise normal. Magnetic resonance imaging revealed a large cervicothoracic syrinx and a Dandy-Walker cyst obstructing the foramen magnum. INTERVENTION The cystoperitoneal shunt was revised. The patient's headaches resolved, and follow-up imaging demonstrated resolution of the syrinx and disimpaction of the foramen magnum. CONCLUSION Disimpaction of the foramen magnum can resolve syringomyelia in patients with the Dandy-Walker complex. This can be achieved by a shunt procedure or by formal foramen magnum decompression. The rarity of the association between the Dandy-Walker complex and syringomyelia prevents firm conclusions from being made regarding the best management strategy for this condition.

Abstract
Neuroendoscopic third ventriculostomy (NTV) has superseded shunting as the treatment of choice in non-communicating hydrocephalus. Intracranial developmental anomalies have been considered to be relative contraindications for this procedure. We present one patient with a Dandy-Walker malformation and another with septo-optic dysplasia who presented with hydrocephalus. An NTV was performed successfully in both patients using a flexible neuroendoscope and utilising transendoscopic Doppler ultrasound to ensure a safe target area for ventriculostomy.

Abstract
OBJECTS Forty-two patients with Dandy-Walker syndrome who were treated with different surgical modalities over a period of 8 years, from 1988 to 1996, at the Sanjay Gandhi Post Graduate Institute of Medical Sciences were reviewed in the present study. METHODS All the patients presented with hydrocephalus at the time of diagnosis. Association of other CNS anomalies was detected in 9 (22%) patients. Vermian hypoplasia was present in 36 (88%) cases, while cerebellar hypoplasia was documented in 27 (59%) of these patients. The treatment modality for these cases has continued to change in our institution over the years. Initially the ventriculoperitoneal shunt was the treatment of choice and was performed in 28 (66%) patients. Subsequently shunting of the cyst to the peritoneal cavity was performed in 7 (16%) patients. More recently, 3 of our patients were treated by fenestration of the cyst membrane and 4 others (9%), by ventriculocystoperitoneal shunting procedures. In this study the additional insertion of cystoperitoneal shunts was required in 8 (27%) of the 28 patients who had primary ventriculoperitoneal shunt procedures, because of either nonresolution or reappearance of a posterior fossa cyst. Six out of the 7 cases of primary cystoperitoneal shunts required additional ventriculoperitoneal shunt diversion because of persistent ventricular dilatation. In the group of 4 patients with primary ventriculocystoperitoneal shunts, only 1 patient required shunt revision. The patients on whom cyst membrane fenestration was performed required no additional procedures, except for 1 who already had a ventriculoperitoneal shunt in situ. CONCLUSIONS Therefore, 18 of the total 42 patients could ultimately be made asymptomatic by ventriculocystoperitoneal shunting for one or the other of these reasons.

Abstract
INTRODUCTION The association of external capillary hemangiomas with intracranial malformations (vascular or nonvascular) was first described by Pascual-Castroviejo in 1978. The commonest anomalies found included: Dandy-Walker syndrome, cerebellar hypoplasia, arterial angiomas and alterations in the origin or distribution of the main cerebral arteries. In 1996 the same author named it the 'hemangiovascular complex syndrome'. The syndrome association is very similar, perhaps even identical, to that recently described in the English literature under the heading of PHACE. CLINICAL CASES We describe two new cases of facial hemangioma, Dandy-Walker type posterior fossa malformation and hypoplasia of the carotid-vertebral trunk ipsilateral to the facial hemangioma. The first patient, a three year old girl had needed a ventriculo-peritoneal shunt for hydrocephalus secondary to a Dandy-Walker malformation. During the third month she had severe symptoms of laryngeal obstruction due to the angiomatous lesion and was satisfactorily treated with corticosteroids. At the present time her psychomotor development seems normal on neurological examination and evaluation. The second patient, a thirteen year old boy, besides showing the characteristic features of this syndrome also had attention-deficit hyperactivity and clumsy movements. In both cases the facial hemangioma was present at birth and gradually became smaller although it did not disappear completely. CONCLUSION It is important to know about this neurocutaneous syndrome to avoid confusion with similar conditions such as the Sturge-Weber syndrome, so as to carry out suitable clinical investigations: cerebral magnetic resonance, angio-resonance of the intracranial vessels and supra-aortic trunks, arteriography, echocardiography and ophthalmological assessment and to prevent signs of upper respiratory tract obstruction which may be very serious.

Abstract
A neonate presented with Dandy-Walker syndrome manifesting as a large posterior cranial fossa cyst, aplasia of the lower cerebellar vermis, and elevation of the confluence of the sinuses but without hydrocephalus. A cystoperitoneal shunt was placed at one month after birth. The cyst diminished in size, and marked development of the cerebellar hemispheres and descent of the confluence of sinuses were observed, but not vermis development. The primary pathology of Dandy-Walker syndrome is posterior cranial fossa cyst formation due to passage obstruction in the fourth ventricle exit area and aplasia of the lower cerebellar vermis. The first choice of treatment in patients with Dandy-Walker syndrome in whom the cerebral aqueduct is open is cystoperitoneal shunt surgery, regardless of the presence or absence of hydrocephalus.

Abstract
PURPOSE To report two cases of successful tracheal intubation in difficult pediatric airways using a conventional laryngeal mask airway (LMA) with an extended polyvinyl chloride (PVC) tube after laryngeal assessment with a fibreoptic device. CLINICAL FEATURES Two cases, Dandy-Walker and Pierre Robin syndromes, were scheduled for surgery. They were premedicated with 0.5 mg x kg(-1) promethazine p.o. 90 min before surgery. Both patients arrived in the operating room sedated, with dry mouth, and without evidence of increased intracranial tension or airway obstruction. Inhalational induction with isoflurane 0.5-3% was commenced. Conventional tracheal intubation was impossible in both cases. In each an LMA was inserted to maintain ventilation, anesthesia, and to facilitate intubation. Fibreoptic bronchoscopy was used to assess the larynx, followed by blind intubation via the LMA using extended PVC tracheal tube (TT). Anesthesia was maintained during intubation using Mapleson F anesthesia circuit attached to a connector with fibreoptic bronchoscope adapter. CONCLUSION This report describes the assessment of the airway with fibreoptic bronchoscopy after LMA insertion facilitated blind tracheal intubation in two children with difficult airways.

Abstract
Since the Dandy-Walker syndrome was first described by Dandy and Blackfan, Taggart and Walker, the many variants of posterior fossa anomalies, the appropriate management of these malformations and the clinical outcome have been the subjects of controversy. Surgery of the posterior fossa with membrane excision was initially the preferred method of treatment. Unfortunately, there was a high rate of complications, and many of the patients treated in this way still needed a shunting system. Ventricular-peritoneal and/or cysto-peritoneal shunting is commonly used to treat symptomatic posterior fossa cysts of Dandy-Walker malformations and hydrocephalus. Cysto-peritoneal shunt implantation only was associated with a high rate of complications, and most patients so treated needed a ventriculo-peritoneal shunt in addition. According to the literature, combined ventriculo-peritoneal and cysto-peritoneal shunting is needed for satisfactory decompression of Dandy-Walker cyst and hydrocephalus in between 16% and 92% of cases. We report on a young patient with a Dandy-Walker malformation who needed drainage of the posterior fossa and a ventricular shunt. We decided to drain the cyst and the supratentorial ventricles via a single, especially prepared, catheter with many perforations. The catheter was inserted under ultrasound guidance. The tube was inserted from the left lateral ventricle through the foramen of Monro into the III ventricle and downwards into the cyst. Intraoperatively, an immediate decrease in the size of the cyst and the supratentorial ventricles was observed. Postoperative MRI confirmed the exact position of the catheter and sufficient drainage of the posterior fossa cyst and the ventricles. Six months later the girl was seen in our outpatient department. Clinical examination showed no neurological deficit, and MRI demonstrated sufficient drainage of the ventricles and the Dandy-Walker malformation, and in addition hypoplasia of the corpus callosum.

Abstract
We report the case of a 2-year-old child who sustained a permanent diabetes insipidus following a third ventriculostomy for hydrocephalus from a Dandy-Walker syndrome. Ventriculostomy, used for therapy of non-communicating hydrocephalus, can cause complications such as diabetes insipidus. The latter has rarely been reported and is usually transient. Following ventriculostomy, a close postoperative surveillance is essential, especially in children.

Abstract
A neonate presented with Dandy-Walker syndrome associated with occipital meningocele and spinal lipoma, manifesting as soft masses on the skull and lumbosacral regions. Magnetic resonance imaging demonstrated a large posterior fossa cyst between the fourth ventricle and occipital meningocele, but the aqueduct was patent and there was no sign of hydrocephalus. A cyst-peritoneal shunt was emplaced at the age of 8 days followed by partial removal of the spinal lipoma and untethering of the cord at the 3 months. Follow-up examination of age 3 years found almost normal development, although the cyst still persisted.

Abstract
Multi-stage reduction cranioplasty was performed on two children with severe macrocephaly secondary to hydrocephalus. One patient underwent a four-stage operation, and the other underwent a two-stage operation. The postoperative course of both patients was uneventful. Reduction cranioplasty improved quality of life for both patients, and good cosmetic results were achieved. Reduction cranioplasty is effective for the treatment of macrocephaly, and multi-stage surgery can reduce the associated risks.

Abstract
Small-bowel obstruction caused by knotting of a peritoneal shunt catheter is an extremely rare and severe complication of a ventriculoperitoneal (VP) shunt. In the 1-week-old female infant reported here who had a VP shunt, inability to remove the peritoneal catheter was followed by small-bowel obstruction and necrosis due to intestinal strangulation in a tight loop of the catheter. An uncomplicated primary resection of the necrotic segment was followed by placement of a temporary ventriculoatrial shunt. The authors suggest that when withdrawal of the peritoneal part of a VP shunt meets with resistance, an intraoperative radiograph should be obtained to assess the position of the remaining catheter. If knotting is observed, an attempt to straighten the catheter with a guide wire is worthwhile. Should this fail, immediate laparoscopy or laparotomy is indicated.

Abstract
In this article we report the cases of an 11-year-old girl who presented with an occipital atretic cephalocele and 2 of her siblings who had similar occipital lesions. Neuroimaging studies in these three instances showed a spectrum of posterior fossa cystic malformations. The girl's parents and a further sibling were also investigated by neuroimaging studies that proved to be normal. The familial occurrence of cephaloceles in general, and of atretic cephaloceles in particular, seems to be very rare in the absence of a known syndrome. Current literature on the familial presentation of cephaloceles and of Dandy-Walker complex is briefly reviewed. To the best of our knowledge this is the first description of the familial presentation of atretic cephaloceles not associated with a recognized syndrome.

Abstract
Fifty children with developmental retrocerebellar cysts of the posterior fossa, treated over an 11-year period, were assessed. The cysts were classified according to a morphological classification based on axial computerized tomography scans in order to assess the usefulness of this classification with regard to treatment and outcome. There were 35 patients with the Dandy-Walker complex and 15 patients with posterior fossa cysts. All surgically treated patients had cerebrospinal fluid shunting as the only form of treatment. Cystoperitoneal shunts were the treatment of choice. Although the morphological classification has relevance with regard to the embryological development of the cyst, it does not influence the selection of treatment nor the surgical outcome following shunt insertion.

Abstract
Hydroephalus of childhood may be associated with intracranial haemorrhage, infection, aqueductal stenosis, Arnold-Chiari malformation (spina bifida), tumours or more uncommonly with the Dandy-Walker syndrome (DWS). We present our experience with the management of this condition over a 10-year period. Twelve children with a definite diagnosis of DWS are reviewed with regard to the age at diagnosis, investigations, treatment, associated problems and overall outcome. Two patients died; there was a high incidence of mental retardation (65%) and associated problems. All but one child had ventriculo-peritoneal shunting and two had cysto-peritoneal shunts in addition to their V-P shunts. There were no familial cases; one child had a chromosomal abnormality. Although the long-term outcome is dismal in most cases, about 35% of the children have a reasonable outcome and hence the condition warrants energetic treatment.

Abstract
Treatment of the Dandy-Walker syndrome has included placement of a ventriculoperitoneal shunt alone or in combination with a posterior fossa cystoperitoneal shunt. Complications in shunting are common and are usually related to malfunction or infection. The authors present a case in which the patient developed headaches and focal cranial nerve deficits following infection caused by a cystoperitoneal shunt. Magnetic resonance imaging showed tethering of the brainstem. A posterior fossa craniotomy with microsurgical untethering and cyst fenestration achieved two goals: improvement of the focal cranial nerve deficits and elimination of the cystoperitoneal shunt.

Abstract
Complications of ventriculoperitoneal shunts are reported in 24-47 % of cases. These include mechanical malfunction and infection, cerebrospinal fluid collection, shunt migration, and visceral perforation. Intestinal perforation, most commonly colonic, may be associated with meningitis or cerebral abscess. Gastric migration has been previously described as a late complication related to the use of stiff Raimondi coil-spring peritoneal catheters in children with malnutrition and abdominal adhesions. We report a case of operative gastric perforation, a rare complication which was detected prior to development of symptoms.

Abstract
BACKGROUND The Dandy-Walker syndrome and Dandy-Walker variant usually present as isolated cases of hydrocephalus in pediatric patients. METHODS AND RESULTS THis paper consists of a case report of the adult onset of symptoms in two sisters having Dandy-Walker variant. Such an occurrence has never before been reported in the medical literature. Both patients presented with headaches and progressive neurologic deficit. On computed tomography (CT scan) of the head, both were found to have hydrocephalus, with hypoplasia of the inferior vermis. Both patients were treated successfully with ventriculoperitoneal shunting. A third sister, with a similar history, elected not to undergo CT scanning or surgical treatment. CONCLUSIONS Variants of the Dandy-Walker syndrome may occasionally present clinically in the adult age group. Such an occurrence in siblings is consistent with an underlying genetic etiology.

Abstract
A 1-month-old infant with a Dandy-Walker malformation underwent the placement of a ventriculoperitoneal shunt to treat progressive hydrocephalus. On the initial computed tomographic scan, a subependymal cystic lesion larger than 1 cm in diameter was noted in the head of the right caudate nucleus, which enlarged to 3 cm in diameter on follow-up imaging studies over the course of a year. Biopsies taken at the time of fenestration failed to show the presence of neoplasia. This appears to be the first reported case of a cyst of this nature to show progressive enlargement.

Abstract
In children with Dandy-Walker syndrome (DWS), the relationship between cerebellar appearance on imaging and either cerebellar function or intellect is unknown. To evaluate those relationships, we retrospectively studied 20 patients with DWS treated in our institution between 1978 and 1994. The patients were treated with ventriculoperitoneal, cystoperitoneal, or ventriculocystoperitoneal shunts. Intellectual and cerebellar function were determined from neurological and developmental testing. Cerebellar development was evaluated by measuring cerebellar and posterior fossa volumes from computed tomography images; the ratio of cerebellar size to posterior fossa size was considered to reflect cerebellar development. The cerebellar function was normal in 50% and the intellectual function in 45% of the patients. There was no correlation between cerebellar size and intellectual development or cerebellar function. There was also no correlation between the type of shunt and the subsequent cerebellar size. We conclude that there is no relationship between the cerebellar development evident on computed tomography scans and the cerebellar or the intellectual function of children with DWS. We, therefore, infer that treatment of Dandy-Walker cysts with posterior fossa shunts is unlikely to enhance the cerebellar function.

Abstract
Fourth-ventricular shunting is commonly used to treat symptomatic posterior fossa cysts of the Dandy-Walker malformation and trapped fourth ventricle. Although the benefits of this procedure have been widely reported, there is a paucity of data on the pitfalls of posterior fossa shunting in the neurosurgical literature. During the 4-year period from July 1989 to June 1993, we placed fourth-ventricular shunts in 12 patients. Remarkably, 5 patients suffered complications related to posterior fossa catheter placement (42% rate). Three of these patients developed new cranial nerve dysfunction caused by direct injury to the floor of the fourth ventricle, 1 patient suffered an intracystic hemorrhage and acute shunt malfunction, and 1 patient had the catheter tip in the brainstem on postoperative studies without new neurological deficit. We conclude that placement of fourth-ventricular shunts can be fraught with complications which we believe is related to technique. We propose that altering the trajectory of the ventricular catheter from our usual midline technique to a more lateral position will lessen the chances for injury to the floor of the fourth ventricle. In this manner we hope to decrease our incidence of complications for this procedure.

Abstract
We present two cases of ventricular obstruction in which shunting of intracranial cysts resulted in the unexpected finding of ventricular enlargement. By imaging criteria this suggested shunt malfunction [corrected]; however, the clinical presentation dramatically improved. The probable mechanism for this diagnostic pitfall is discussed.
