Abstract:

OBJECTIVE: To evaluate the frequency and degree of severity of abnormalities in the auditory pathways in patients with Chiari malformations type I and II. METHOD: This is a series-of-case descriptive study in which the possible presence of auditory pathways abnormalities in 75 patients (48 children and 27 adults) with Chiari malformation types I and II were analyzed by means of auditory evoked potentials evaluation. The analysis was based on the determination of intervals among potentials peak values, absolute latency and amplitude ratio among potentials V and I. RESULTS: Among the 75 patients

Abstract:

Arnold chiari II malformation is a congenital CNS abnormality characterised by downward displacement of posterior fossa structures into spinal canal. This malformation is a causative factor of death in neonates and infants. A thorough understanding of the direct and indirect sonographic findings is necessary for the diagnosis of chiari II malformation in developing fetus.

Abstract:

✓ The authors report their recent experience with 14 meningomyelocele patients with the Arnold-Chiari II malformation. Three major types of fourth ventricle anomalies seen in the Arnold-Chiari II malformation are defined, based on preoperative magnetic resonance imaging and intraoperative ultrasound studies. The Type A deformity is defined as no cystic dilatation of the fourth ventricle. In the Type B anomaly, there is intracranial dilatation of the fourth ventricle. The Type C deformity involves intraspinal dilatation of the fourth ventricle, either dorsal to the cord or within the substance

The formation of hydrocephalus in Arnold – Chiari type II anomaly has an obstruction mechanism, which consists in disconnecting the cerebrospinal fluid system of the brain and the cerebrospinal fluid space, turning off the damper function. Having considered the pathogenetic foundations and anatomical variants of the relationship between the structures of the posterior cranial fossa, it was revealed that endoscopic third ventriclostomy does not restore the communication of two liquor compartments and, as a result, cannot be a method of treating hydrocephalus in this pathology.

Bending and stretching of the neck is restricted, and anesthetic management is problematic in patients with the disorder.

Abstract:

Introduction: Myelomeningocele is one of the most common types of closed neural tube defect. Repair of this malformation should be conducted as early as possible to avoid contamination with the external environment. In 2011, an American randomized clinical trial was carried out showing there are neurological benefits in performing intrauterine surgery compared to postnatal surgery, with fewer cases of cerebrospinal fluid shunt and hindbrain herniation. In Brazil, this technique is not yet widespread and many services perform repair after birth. Objective: To describe the epidemiological profil

Abstract:

Introduction: Myelomeningocele (MMC) is an embryonic malformation that occurs in the first four weeks of gestation due to a failure in the closure of the neural tube. They have multifactorial etiology such as genetic and environmental factors that affect folic acid metabolism. Several anomalies may be associated with MMC, with the occurrence of hydrocephalus and Arnold Chiari type II malformation being most present. Surgical repair should ideally occur within the first 24 hours after birth to prevent or decrease the risk of infection, preservation of all viable nerve tissue, anatomical reconst

Objective: To determine the frequency of congenital malformations diagnosed by prenatal ultrasound in the “Dr. Freddy Guevara Zuloaga” Perinatology Unit of the University Hospital of Caracas, Venezuela, in the period between January 1, 2015 and December 31, 2020. Methods: Retrospective, descriptive, cross-sectional study. The statistical records of the Unit were reviewed, with a population of 56,712 and 1844 patients were included in accordance with the inclusion criteria. Results: A general prevalence of 3.3% was obtained. The largest number of studies was conducted in 2016 (12,781). The high

Abstract:

Abstract BACKGROUND AND IMPORTANCE: This is the first case report of clipping a cerebral aneurysm in a patient with Loeys-Dietz syndrome (LDS). LDS is a newly described autosomal dominant connective tissue disease with systemic vascular involvement. Unique to this syndrome is the development of aneurysms at a young age with the propensity of dissection or rupture at a stage that is earlier than when surgical intervention is typically indicated. We describe the nuances in intraoperative and postoperative management. CLINICAL PRESENTATION: A 31-year-old woman who recently received a diagnosis of

Abstract:

Introduction Klinefelter’s syndrome (KS) is considered as a genetic risk factor for intellectual disability and specifically for impairment on verbal skills. Prenatal and perinatal morbidity concurrent with this diagnosis determine the entity and typology of neurodevelopmental deficits.

Abstract OBJECTIVE This report describes two shunted patients evaluated with continuous intracranial pressure (ICP) monitors for worsening headaches and subsequently diagnosed with obstructive sleep apnea. CLINICAL PRESENTATION AND INTERVENTION ICPs were monitored with strain-gauge sensors inserted into the frontal cortex. After the initial diagnosis of sleep apnea, 8-hour attended polysomnography was performed in each patient. Both patients showed apnea-hypopnea indices greater than 15. Consequently, a “split-night study” was performed to evaluate treatment with titrated nasal continuous posi
