Mortality, Functional Status, and Quality of Life after 5 Years of Patients Admitted to Critical Care for Spontaneous Intracerebral Hemorrhage.

BACKGROUND: The objective of this study was to assess long-term outcome in patients with spontaneous intracerebral hemorrhage admitted to the intensive care unit. METHODS: Mortality and Glasgow Outcome Scale, Barthel Index, and 5-level EQ-5D version (EQ-5D-5L) scores were analyzed in a multicenter cohort study of three Spanish hospitals (336 patients). Mortality was also analyzed in the Medical Information Mart for Intensive Care III (MIMIC-III) database. RESULTS: The median (25th percentile-75th percentile) age was 62 (50-70) years, the median Glasgow Coma Score was 7 (4-11) points, and the median Acute Physiology and Chronic Health disease Classification System II (APACHE-II) score was 21 (15-26) points. Hospital mortality was 54.17%, mortality at 90 days was 56%, mortality at 1 year was 59.2%, and mortality at 5 years was 66.4%. In the Glasgow Outcome Scale, a normal or disabled self-sufficient situation was recorded in 21.5% of patients at 6 months, in 25.5% of patients after 1 year, and in 22.1% of patients after 5 years of follow-up (4.5% missing). The Barthel Index score of survivors improved over time: 50 (25-80) points at 6 months, 70 (35-95) points at 1 year, and 90 (40-100) points at 5 years (p < 0.001). Quality of life evaluated with the EQ-5D-5L at 1 year and 5 years indicated that greater than 50% of patients had no problems or slight problems in all items (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). In the MIMIC-III study (N = 1354), hospital mortality was 31.83% and was 40.5% at 90 days and 56.2% after 5 years. CONCLUSIONS: In patients admitted to the intensive care unit with a diagnosis of nontraumatic intracerebral hemorrhage, hospital mortality up to 90 days after admission is very high. Between 90 days and 5 years after admission, mortality is not high. A large percentage of survivors presented a significant deficit in quality of life and functional status, although with progressive improvement over time. Five years after the hemorrhagic stroke, a survival of 30% was observed, with a good functional status seen in 20% of patients who had been admitted to the hospital.

Neuroendoscopic transventricular transchoroidal approach for access to the posterior zone of the third ventricle or pineal region.

The endoscopic transventricular transchoroidal approach facilitates entry into the posterior part of the third ventricle, allowing a visualization field from the foramen of Monro to the pineal region through this anatomical corridor. Combined surgery to treat the target lesion and possible endoscopic third ventriculostomy (ETV) can be performed through a single burr hole. A detailed description of this surgical technique is given, and a series of cases from our center is presented. This retrospective study included patients with lesions in the pineal region or posterior zone of the third ventricle who underwent surgery between 2004 and 2022 in our center for tumor biopsy or endoscopic cyst fenestration. In nine cases, the transchoroidal approach was performed. Demographic and clinical variables were collected: sex, age at diagnosis, clinical presentation, characteristics of the lesion, pathological diagnosis, characteristics of the procedure, complications, subsequent treatments, evolution, follow-up time, and degree of success of the endoscopic procedure. The mean and range of the quantitative variables and frequency of the qualitative variables were analyzed, together with the statistical significance (p < 0.05). Surgical planning was carried out by performing a preoperative MRI, calculating the ideal entry point and trajectory for each case. The preoperative planning of the surgical technique is described in detail. Of our sample, 55.6% were women, with a mean age of 35 years (7-78). The most common clinical presentation was intracranial hypertension (55.6%), with or without a focus. Eight patients presented hydrocephalus at diagnosis. The most frequent procedure was endoscopic biopsy with ETV (66.7%). The pathological diagnosis varied widely. Procedure-related complications included one case of self-limited bleeding of the choroidal fissure at its opening and one intraventricular hemorrhage due to tumor bleeding in the postoperative period. Non-procedure-related complications comprised two ETV failures and one case of systemic infection, while late complications included one case of disease progression and one case of radionecrosis. Four patients died, one due to poor neurological evolution after post-surgical tumor bleeding and three due to causes unrelated to the procedure. The rest of the patients had a favorable evolution and were asymptomatic or stable. The transchoroidal approach through a single burr hole is a feasible and safe option for access to the posterior part of the third ventricle. Proper planning of each case is necessary to avoid complications.

Endoscopic third ventriculostomy in children with chronic communicating congenital hydrocephalus: a single-center cohort retrospective analysis.

OBJECTIVE: The aim of this study was to analyze the role of endoscopic third ventriculostomy (ETV) in the treatment of pediatric chronic communicating congenital hydrocephalus (CCCH). MATERIAL AND METHODS: This retrospective study comprised a series of 11 children with CCCH treated with ETV. Data were recorded on gender, history, presenting symptoms, age at surgery, complications during surgery, clinical evolution, ETV survival, and follow-up period. Radiological variables including ventricular and cephalic diameters were also recorded to determine a series of ventricular indexes in magnetic resonance imaging (MRI) before and after the ETV procedure. The procedure was considered to be successful when there was clinical stability or improvement accompanied by a reduction in the radiological indexes in the postoperative control images, such that there was no need to place an extrathecal cerebrospinal fluid shunt. RESULTS: Over a mean follow-up period of 35.8 months (range: 6-108 months) from the ETV procedure, three patients required shunt placement; one of these was due to early failure in an 8-month old girl, the only patient younger than 12 months in our series. The radiological indexes were reduced in all patients except for one of the cases of ETV failure. The mean ETV survival among the successful cases was 32.1 months (range: 6-108 months), whilst that of the failed cases was 16 months (range: 6-108 months). CONCLUSION: Although studies with larger sample sizes are needed, ETV appears to be a promising option for the treatment of this type of patient with CCCH.

Life-threatening idiopathic intracranial hypertension: the role of venous sinus stenting.

BACKGROUND: Idiopathic intracranial hypertension (IIH) is a clinical syndrome characterised by raised intracranial pressure with no discernible aetiology. It is relatively rare in children and its demographic features may differ from those of adults. The relationship between IIH and venous sinus stenosis (VSS) is well known. As VSS plays an important role in the pathophysiology, treatments have been developed aimed at improving venous blood outflow in refractory IIH. In the last two decades, venous sinus stenting has emerged as a treatment option in cases where stenosis is documented. METHODS AND RESULTS: The scientific literature on paediatric cases of IIH and its treatment with venous sinus stenting was analysed. We present the case of a 6-year-old girl with a life-threatening presentation of IIH, who was treated with transverse sinus stenting and a lumboperitoneal shunt. We summarise the characteristic of paediatric stenting cases reported and review the literature focusing on the main aspects of venous sinus stenting. CONCLUSION: VSS stenting could be a treatment tool for the acute presentation of IIH with severe symptoms and VSS plus an elevated trans-stenotic pressure gradient. However, in some cases, additional surgical treatment may be necessary.

Analysis of complications in intraventricular neuroendoscopy in children: proposal for a standardization system.

Although intraventricular neuroendoscopy is considered a minimally invasive technique with good results, there is nevertheless a risk of developing certain complications. As no agreement apparently exists concerning the classification of these complications, we aim to propose a form of classification based on the results of our series, comparing them with recent publications. We undertook a retrospective study of 170 children who underwent intraventricular neuroendoscopy between 2003 and September 2020 at our center. Data were recorded on demographic and clinical variables: age, gender, presenting symptoms, etiology, number of procedures, type of procedure, and complications. Complications were divided into two main groups, intraoperative and postoperative, and in subgroups. The intraoperative complications included one group of systemic alterations and another group of surgical problems. The postoperative complications were divided into six groups: systemic, neurologic, hormone, fluid, hemorrhagic and death. A total of 202 neuroendoscopic procedures were performed in 170 children. The mean age at first surgery was 71 months (22-122). The most common etiology of the hydrocephalus was intraventricular tumors (32.9%), followed by aqueductal stenosis (13.5%). The most usual presenting sign was intracranial hypertension. The procedure most used was third ventriculostomy (62.9%). During the procedures, we experienced 5 surgical intraoperative complications (2.47% per procedure). In the postoperative period, there were 23.7% systemic complications per procedure, 12.87% neurologic, 8.41% hormone, 10.9% fluid, 0.5% hemorrhagic, and 0.99% for postoperative death. The rate of complications associated with intraventricular neuroendoscopy was similar in our series to those already published. Comparative studies require standardization for the analysis of neuroendoscopic complications.

Neuroendoscopic biopsy: analysis of a series of 80 patients.

Neuroendoscopy enables diagnostic biopsy of intraventricular and/or paraventricular tumors and the simultaneous treatment of associated hydrocephalus in selected cases. The objective of this paper was to analyze the effectiveness and safety of this procedure. This retrospective study included 80 patients between 2 months and 78 years old diagnosed with intraventricular and/or paraventricular expansive lesion who underwent neuroendoscopic biopsy from 2004 to 2016. Collected variables were gender, age at diagnosis, clinical presentation, tumor location, surgical technique, management of hydrocephalus, pathological findings, procedure-related complications, and follow-up time. Neuroendoscopic biopsy was performed in 80 patients. Mean age at diagnosis was 27 years, and 52.5% were men. According to the Depreitere Classification, 71 were level I (conclusive diagnosis), 1 level III (problematic categorization), and 8 level IV (non-interpretable diagnosis). The most frequent diagnosis was grade I astrocytoma (14%). Diagnostic success per patient was 88.7%. Sixty-nine patients had hydrocephalus at diagnosis, 37 of whom were treated with endoscopic third ventriculostomy (ETV), with septostomy (SPT) in 14, and only SPT in 4. Twenty-eight patients underwent ventricular peritoneal shunt (VPS), with SPT in 20. The ETV success rate was 70.9%. The complication rate per patient was 11%: five patients presented intraventricular hemorrhage, three of whom died; one patient presented cerebrospinal fluid fistula; three presented transient oculomotor impairment. Postoperative follow-up was from 1 month to 12.4 years (mean 45 months). Neuroendoscopy is an effective procedure for the pathological diagnosis of intraventricular and paraventricular tumors, allowing the treatment of associated hydrocephalus. Nevertheless, it is not exempt from serious complications and requires proper training.

LOVA: the role of endoscopic third ventriculostomy and a new proposal for diagnostic criteria.

The diagnostic criteria and management of this condition continue to be a topic of debate in the literature. The term definitive symptomatic LOVA (longstanding overt ventriculomegaly in adults) is applied to patients that fulfil a series of diagnostic criteria,which are reviewed in our paper. The main subject of our study is to propose a rearrangement of the criteria for the diagnosis of this entity and adjusted treatment strategies. We present our data evaluating the role of endoscopy in this pathology. This descriptive and analytical study comprised 27 adult patients with LOVA who underwent endoscopic third ventriculostomy (ETV). Data regarding age, gender and onset of symptoms, a previously implanted shunt, clinical examination and radiological findings at the time of diagnosis, and the intracranial pressure (ICP) recordings in some cases, were carefully retrospectively reviewed. ETV success was determined based on clinical state and radiological criteria. ETV was performed in all 27 cases. Mean follow up period was 4.2 years (6 months to 8 years). 2/27 patients (7.40%) were lost to follow-up. The overall success rate for ETV was 76% (21/25 patients). ETV resulted in shunt independency in two of the three patients with a previous shunt. Based on our results, we believe that ETV must be considered as the treatment of choice for patients with symptomatic LOVA.

Ethmoidal meningoencephalocele and CSF leak after posthaemorrhagic ventricular dilatation in a newborn child.

BACKGROUND: Rhinoliquorrhoea suggests a communication between the subarachnoid space and the sinonasal tract. Clinical presentation includes clear nasal discharge, headache, pneumocephalus, meningitis or brain abscess. Cerebrospinal fluid (CSF) leaks are mostly of traumatic origin (skull base fractures), iatrogenic (secondary to endoscopic endonasal surgery) or associated with tumour aetiology. Occasionally, hydrocephalus has been the cause of rhinoliquorrhoea in adults, presumably secondary to the chronically raised intracranial pressure with skull base erosion and meningocele. To our knowledge, the association of hydrocephalus and ethmoid meningoencephalocele/CSF leak has not been previously reported in a newborn child. CASE PRESENTATION: We present the case of a 9-month-old girl who was referred for rhinorrhoea. She had a history of posthaemorrhagic ventricular dilatation. Brain computed tomography (CT) and magnetic resonance imaging (MRI) showed a left ethmoidal meningoencephalocele and small ventricular size. The meningoencephalocele was surgically repaired using an intradural subfrontal approach. During the postoperative period, after the transient lumbar drain was withdrawn, she developed symptomatic hydrocephalus. Ventriculoperitoneal shunting was required. CONCLUSION: Progressive ventricular dilatation may arise from a meningoencephalocele/CSF leak in paediatric patients. Early identification and repair of the meningoencephalocele are critical to avoid development of complications.

Prognosis of atypical teratoid rhabdoid tumors (AT/RT) treated with multimodal therapy protocols. Report of our series.

OBJECTIVE: Atypical teratoid rhabdoid tumors (AT/RT) of the central nervous system are rare, very aggressive embryological tumors, typically diagnosed in young patients and having a low survival rate after diagnosis. The aim of this study was to emphasize, based on the latest results in the literature, the need for protocols for multidisciplinary treatment in these patients. MATERIAL AND METHODS: We report our series of 3 cases treated, diagnosed and followed up between 2009 and 2014. They were treated with multimodal therapy protocols (Rhabdoid SIOP-2007 and European Rhabdoid Registry EU-RHAB-2010). In addition, we carried out a literature review. RESULTS: Two of our 3 cases (supratentorial and spinal tumors) did not show any progression of the disease after long follow-up, in contrast with most of the cases available in the literature. The second patient had a shorter survival. CONCLUSIONS: Patient age at the time of diagnosis, supratentorial location of the mass and fewer complications with adjuvant treatments seem to be factors yielding good prognosis for AT/RT tumors. In agreement with the latest international protocols, multidisciplinary treatment is the ideal treatment, consisting of radiotherapy and chemotherapy after complete tumor resection.

Survival analysis of surgically evacuated supratentorial spontaneous intracerebral hemorrhage with intraventricular extension.

OBJECTIVE: To conduct a survival study and evaluation of surgical treatment in a cohort of patients with diagnosis of supratentorial spontaneous intracerebral hemorrhage (ICH). MATERIALS AND METHODS: The study included all consecutive patients with supratentorial ICH admitted to the Intensive Care Units of three Spanish hospitals with Neurosurgery Department between 2009 and 2012. DATA COLLECTED: age, APACHE-II, Glasgow Coma Score (GCS), and pupillary anomalies on admission, intracerebral hemorrhage (ICH) score, location/volume of hematoma, intraventricular hemorrhage (IVH), surgical evacuation alone or with additional external ventricular drain, and 30-days survival and at hospital discharge RESULTS: A total of 263 patients were included. Mean age: 59.74±14.14 years. GCS: 8±4 points, APACHE II: 20.7±7.68 points. ICH Score: 2.32+1.04 points. Pupillary anomalies were observed in 30%. The 30-day mortality: 51.3% (45.3% predicted by ICH-score), and 53.2% at hospital discharge. A significant difference (p=0.004) was observed in hospital mortality rates between surgically treated patients (39.7%, n=78) versus those conservatively managed (58.9%, n=185); specifically in those with IVH surgically treated (34.2%, n=38) versus non-operated IVH (67.2%, n=125), p<0.001. No significant difference was found between mortality rates in patients without IVH. Multiple logistic regression analysis showed an OR for surgery of 1.04 (95% CI; 0.33-3.22) in patients without IVH versus 0.19 (95% CI; 0.07-0.53) in patients with IVH (decreased mortality with surgical treatment). The propensity score analysis for IVH patients showed improved survival of operated group (OR 0.23, 95% CI; 0.07-0.75), p=0.01. CONCLUSIONS: Hospital mortality was lower in patients who underwent surgery compared to patients conservatively managed, specifically for the subgroup of patients with intraventricular hemorrhage.

Endoscopic endonasal resection of clival xanthoma: case report and literature review.

Bone xanthoma is an extremely rare and benign tumor in terms of its nature and growth over time. We describe the first case coexisting with ventriculomegaly secondary to aqueduct stenosis (non-tumoral hydrocephalus), the second xanthoma of the clivus described to date. The patient was a 51-year-old woman with headaches and absence seizures. Axial T1-weighted MRI showed a well-demarcated, hypointense, osteolytic, 25 × 18 × 15 mm lesion with cortical erosion located at the right margin of the clivus. Sagittal T2-weighted MRI demonstrated a hypointense mass without associated edema. Sagittal gadolinium-enhanced T1-weighted MRI showed contrast uptake with a partially hypointense rim. The increased ventricular size without periventricular edema was associated with aqueduct stenosis, and there was no contiguity with the tumor. A neuronavigation image-guided transsphenoidal approach was chosen to perform a macroscopically complete resection. Intraoperative histopathological study showed a chordoma of the clivus. Exhaustive postsurgical study revealed the benign nature of a bone xanthoma. Given the finding of a clival lesion, the differential diagnosis is essentially with other malignant entities with a rapidly fatal outcome, such as metastases, or with a possible invasive evolution, such as clivus chordomas. This report describes the clinical, radiological, and pathological keys for such differentiation in order to avoid unnecessarily aggressive treatment with ablative surgery and radiotherapy.

[Applicability of the da Vinci robotic system in the skull base surgical approach. Preclinical investigation]. / Aplicabilidad del sistema da Vinci en el abordaje transoral a la base del cráneo. Investigación preclínica.

INTRODUCTION: The role of robotic surgery is well established in various specialties such as urology and general surgery, but not in others such as neurosurgery and otolaryngology. In the case of surgery of the skull base, it has just emerged from an experimental phase. OBJECTIVE: To investigate possible applications of the da Vinci surgical robot in transoral skull base surgery, comparing it with the authors' experience using conventional endoscopic transnasal surgery in the same region. METHODS: A transoral transpalatal approach to the nasopharynx and medial skull base was performed on 4 cryopreserved cadaver heads. We used the da Vinci robot, a 30° standard endoscope 12mm thick, dual camera and dual illumination, Maryland forceps on the left terminal and curved scissors on the right, both 8mm thick. Bone drilling was performed manually. For the anatomical study of this region, we used 0.5cm axial slices from a plastinated cadaver head. RESULTS: Various skull base structures at different depths were reached with relative ease with the robot terminals CONCLUSIONS: Transoral robotic surgery with the da Vinci system provides potential advantages over conventional endoscopic transnasal surgery in the surgical approach to this region.

[Brachial plexus compression from supraclavicular encapsulated fat necrosis. A case report]. / Plexopatía braquial compresiva por necrosis grasa encapsulada supraclavicular. Caso clínico.

We report the case of a 44-year-old male, lacking clinical history of previous illness, who had surgery at our hospital to treat a mass in the supraclavicular space. The patient presented with a 1-month progressive distal paresis of the left arm. The histo-pathological examination of the mass revealed an encapsulated fat necrosis. Fat necrosis is characterised by cystic architecture, encapsulation with fat necrosis within, and inflammatory infiltration of its walls. Neural structure compression secondary to this tumour mass is very rare. Fat necrosis is more frequent in the lower limbs, in areas exposed to trauma. This article is the first report of brachial plexus compression due to supraclavicular fat necrosis.

[Cranial fasciitis: a case report and review of the literature]. / Fascitis craneal: caso clínico y revisión de la literatura.

Cranial fasciitis is an uncommon, rapidly-growing, benign, non-tumoural, myofibroblastic lesion of the skull, found mainly among young children in their first year of life. It is histologically similar to nodular fasciitis and pseudosarcomatous fasciitis. It may mimic more aggressive pathologies, such as sarcomatosis or histiocytosis, due to its rapid, nodular growth in subcutaneous tissue. Complete resection is considered curative and, therefore, entails a low risk of metastases or malignant recurrences. We present the clinical, radiological and pathological findings in a 4-year-old boy with cranial fasciitis in the deep, subcutaneous, soft tissue, with erosion of the outer table of the cranium, which also produced periosteal reaction, while respecting the inner table and meninges. The objective of this article is to highlight the absence of radiotherapeutic or chemotherapeutic adjuvant treatment. In addition, an exhaustive review of the literature is also presented.

Glomangioleiomyoma of the orbit--a case report.

Soft-tissue glomus tumours are benign lesions derived from the glomus bodies, which are specialized arteriovenous shunts that serve a thermoregulatory function and are concentrated in the distal extremities of the dermis. Glomangioleiomyoma is rarely found in the orbit, most likely because of the paucity of smooth muscle and glomus bodies in this location. We report the case of a woman with exophthalmos in whom computerized tomography and magnetic resonance imaging showed a large, lobulated mass in the right intraconal space.

[Isolated traumatic injuries of the axillary nerve. Radial nerve transfer in four cases and literatura review]. / Lesiones traumáticas aisladas del nervio axilar. Experiencia en 4 casos de transferencia nerviosa radial y revisión de la literatura.

OBJECTIVE: To analyze the results of an initial series of four cases of traumatic injuries of the axillary nerve, treated by a nerve transfer from the triceps long branch of the radial nerve. An extensive analysis of the literature has also been made. MATERIALS AND METHODS: Four patients aged between 21 and 42 years old presenting an isolated traumatic palsy of the axillary nerve were operated between January 2007 and June 2010. All cases were treated by nerve transfer six to eight months after the trauma. The results of these cases are analyzed, the same as the axillary nerve injuries series presented in the literature from 1982. RESULTS: One year after the surgery, all patients improved their abduction a mean of 70° (range 30 to 120°), showing a M4 in the British Medical Council Scale. No patient complained of triceps weakness after the procedure. These results are similar to those published employing primary grafting for the axillary nerve. CONCLUSIONS: Isolated injuries of the axillary nerve should be treated with surgery when spontaneous recovery is not verified 6 months after the trauma. Primary repair with grafts is the most popular surgical technique, with a rate of success of approximately 90%. The preliminary results of a nerve transfer employing the long triceps branch are similar, and a definite comparison of both techniques with a bigger number of cases should be done in the future.

[Sciatica secondary to extrapelvic endometriosis affecting the piriformis muscle. Case report]. / Ciatalgia secundaria a endometriosis extrapélvica del músculo piriforme. A propósito de un caso.

OBJECTIVE: We present a case report of symptomatic compression of the right sciatic nerve notch, secondary to piriformis muscle endometriosis, as well as a literature review. MATERIAL AND METHODS: We report the case of a 29-year-old woman with 2-year evolution of right chronic sciatica. During the first year, symptoms were episodic and associated with menstruation. During the second year, sciatica was constant and associated with gait disorder due to sciatic musculature weakness. Mononeuropathy was proved by a neurophysiological study, with MRI and PET studies revealing a mass in the sciatic notch and regional pathological increase in metabolic activity. Surgical treatment was performed in order to release the nerve and obtain a histological sample. RESULTS: The patient was treated by a transgluteal approach, with external neurolysis of the sciatic nerve and resection of an old-blood cyst at the level of the piriformis muscle. This was subsequently reported as endometriosis by histological examination. The sciatica was resolved after surgery. CONCLUSIONS: Extrapelvic sciatic nerve compression by adjacent endometriosis is very infrequent. Muscle denervation and lack of a histological diagnosis led to surgical exploration of the compression area in order to release the nerve, resect the cause of compression and obtain a definitive diagnosis. The procedure improved all symptoms.

[Primary prophylaxis of early seizures after surgery of cerebral supratentorial tumors: Group for the Study of Functional-Sterotactic Neurosurgery of The Spain Society of Neurosurgery recommendations]. / Control de las crisis epilépticas durante el postoperatorio inmediato de los tumores cerebrales supratentoriales: recomendaciones del Grupo de Neurocirugía Funcional y Estereotáctica de la Sociedad Española de Neurocirugía.

Our review of the literature is basically focused on the primary prophylaxis of early seizures after surgery of cerebral supratentorial tumors, with the aim of suggesting several recommendations in medical antiepileptic treatment to avoid this kind of seizures which occur immediately after surgery. In conclusion, it is recommended to provide criteria for prophylaxis of early seizures after surgery of cerebral supratentorial tumors. It́s recommended a one week treatment with antiepileptic drugs in patients who didnt have seizures jet, starting immediately after the surgical treatment. If seizures appear during progress of the disease, a large period treatment will be needed. Preferred antiepileptic treatment is intravenous and with a low interactions profile. Levetiracetam, followed by valproic acid seem to be most appropriated drugs due to their properties and protective effects, particularly for our patients requirements. These recommendations are considered a general proposal to effective clinical management of early seizures after surgery, not taking into account the single circumstances of our patients. Always, clinical features of the patients could modify even significantly these guides in the benefit of each patient.

Re-Do endoscopic third ventriculostomy. Retrospective analysis of 13 patients.

OBJETIVES: Indication for endoscopic third ventriculostomy (ETV) in the treatment for noncommunicating hydrocephalus is widely accepted. There is controversy regarding the indication of a second procedure (re-ETV) when the first has failed. The objective of this work is to revise ETV failures in a series in which re-ETV was performed and to describe the factors related to its prognosis. METHOD: Retrospective study of pediatric patients with ETV failure treated by re-ETV between 2003 and 2018. Gender, age in first and second ETV, time to failure of first ETV, etiology of hydrocephalus, previous presence of shunt, ETV-SS in the first and second ETV, intraoperative findings, success of the second procedure and follow-up were collected. The ETV-SS result was grouped into high (≥ 80), moderate (50-70) or low (≤ 40) scores. Endoscopic procedure failure was considered clinical worsening or the absence of radiological criteria for improvement (reduction in ventricular size or presence of ETV flow artifact in the floor of third ventricle). RESULTS: Of 97 ETV carried out in this period, 47 failures were registered, with 13 re-ETV performed. Of these, 8 were classified as successful (61.53%). Re-ETV was successful in 4/4 cases in which etiology was tectal tumor or aqueduct stenosis. In the group with a high ETV-SS score there was a higher rate of success (75%) than in the group with a moderate score (40%). 9 patients presented shunt prior to first ETV and in them, success was 66.6% compared to 50% in the group without prior shunt. All re-ETV were performed without complications. In 11 of the 13 procedures a closed stoma was found and the remaining 2 cases, we found a punctate opening. The mean follow-up after re-ETV was 61.23 months. CONCLUSION: The selection of patients for re-VET should be cautious. Factors such as age, etiology, and previous shunt (ETV-SS factors) have prognostic influence. However, there are specific factors which indicate favorable prognostic for re-VET such as a longer time to failure of the first procedure, the finding of a closed/punctate stoma or the loss of flow artifact in the follow-up MRI.

Quality of life in children with hydrocephalus treated with endoscopic third ventriculostomy.

OBJECTIVE: The objectives of this study were to determine the quality of life of a pediatric cohort with hydrocephalus treated by endoscopic third ventriculostomy (ETV), using the Hydrocephalus Outcome Questionnaire-Spanish version (HOQ-Sv), and study the clinical and radiological factors associated with a better or worse functional status. METHODS: This cross-sectional study was undertaken between September 2018 and December 2019. It comprised a series of 40 patients ranging from 5 to 18 years old with hydrocephalus treated by ETV. ETV was considered to be successful if there was no need for surgery for the treatment of hydrocephalus after a minimum follow-up of 6 months. The clinical variables included gender, age at hydrocephalus diagnosis, age at the time of ETV, age at completion of the questionnaire, etiology and type of hydrocephalus (communicating or not), prior shunt, repeat ETV, number of neurosurgical procedures, number of epileptic seizures, presenting signs, and follow-up duration until last office revision. The radiological variables were the Evans Index and the pre- and posttreatment frontooccipital horn ratio. An analysis was conducted of the association between all these variables and the various dimensions on the HOQ-Sv, completed by the parents of the patients via telephone or in the outpatient offices. RESULTS: The mean age of the children at ETV was 7 years (range 7-194 months), and on completing the questionnaire was 12 years (range 60-216 months). The mean HOQ scores were as follows: overall 0.82, physical domain 0.86, social-emotional (SE) domain 0.84, cognitive domain 0.75, and utility score 0.90. A history of epileptic crises was a predictive factor for a worse score overall and in the SE and cognitive domains. Factors related to a worse score in the physical domain were a previous shunt, the number of procedures, and the etiology and type of hydrocephalus. The mean follow-up duration from ETV to the last office visit was 5 years (64.5 months). No association was found between the degree of ventricular reduction and the quality of life. CONCLUSIONS: The factors related to a worse score in the different dimensions of the HOQ were a history of epileptic seizures, the number of procedures, communicating hydrocephalus, and having had a previous valve. No association was found between the reduction in ventricular size and the quality of life as measured on the HOQ-Sv.
