“…Sylvius aqueduct stenosis is not a stable condition (1). Functional processes such as deformation of the brain stem due to the ongoing enlargement of the supratentorial ventricles may worsen the obstacle and precipitate acute intracranial hypertension.…”

“…In children and adults, aqueduct width and cross-sectional area have been measured by MRI using the midline sagittal plane, perpendicular to its long axis [14, 15,17] . The aqueductal morphology in AS included a funnel-shaped enlargement of the proximal cerebral aqueduct related to distal obstruction, a diffuse reduction in its caliber reaching complete occlusion, and the presence of an aqueductal web [2,18,19] . In our pathological cases, AS diagnosis was suspected by aqueductal occlusion in 6 cases and funnel shape in 1.…”

“…In almost 75% of patients the etiology of the disorder is not known and in the remaining can be attributed to genetic factors, infection/inflammation, hemorrhage, venous hypertension, or tumors [2] . Classically, this condition is not secondary to an underlying malformation or destructive process, so the severe ventricular dilation is accompanied by an otherwise normal brain anatomy [3,4] .…”

Objective: To describe a technique for the visualization and measurement of cerebral aqueduct diameter through a 2D sagittal median plane, and to report its aspect and measurement in fetuses with aqueductal stenosis (AS). Methods: This was a cross-sectional study of 207 morphologically normal fetuses in low-risk pregnancies between 20 and 36 weeks of gestation. The cerebral aqueduct was visualized transvaginally in a midsagittal plane, and measurements of its greatest diameter (ampulla) were taken independently by an expert and a nonexpert sonographer. In addition, the aqueduct morphology from 7 fetuses with AS and complete follow-up were compared to the reference range. Results: Aqueductal measurements were obtained in 206 of 207 normal fetuses. Aqueductal growth occurred linearly with gestational age. Our method demonstrated excellent interobserver reproducibility. Among the 7 fetuses with AS, the aqueductal lumen could not be identified in 6 and had a funneling aspect in 1. Discussion: Our study demonstrated that it is possible to visualize and measure the cerebral aqueduct directly through a 2D ultrasound median plane. In fetuses with severe ventriculomegaly, the morphology and width of this structure could represent a relevant tool in improving AS diagnosis, differentiating it from other causes of significant ventricular dilation that carry a different outcome.

“…In this process a fenestration is made in the thinned floor of third ventricle which is an attempt to bypass the obstruction in the aqueduct of the Sylvius 1 . The process is not a cure for hydrocephalus rather a process for an alternative to shunt surgery 1,2 . The first open third ventriculostomy was done in 1922.…”

Background: Endoscopic third ventriculostomy (ETV) is the process of intra cranial CSF diversion to relieve the pressure inside the ventricles. This allows the cerebrospinal fluid to flow directly to the basal cisterns, thereby shortcutting any obstruction. It is used as an alternative to a cerebral shunt surgery. Objectives: To observe the Endoscopic third ventriculostomy (ETV) with causal factors and outcome. Methodology: The study was conducted in the Department of Neurosurgery in National Institute of Neurosciences (NINS) during the period from June, 2013 to August, 2014. All the study subjects included in the study were selected for endoscopic third ventriculostomy (ETV) following clinical and radiological diagnosis of hydrocephalus or raised ICP irrespective of age, sex and causal factors. The patients were followed post operatively to follow the outcome. Result: ETV was performed among 38 males and 35 females with a mean age of 24.67 years. Three major causal factors for ETV were aqueductal stenosis, posterior fossa SOL and CP angle tumour observed in 25 (34.3%), 22(30.2%), 11(15.1%) cases respectively. The successful ETV was done in 49 (67.1%) patients varied widely by diagnosis and patient age. Other 32.9% had suffered from several complications like local CSF drainage, local infection, meningitis and subarachnoid haemorrhage and treated conservatively. Conclusion: Endoscopic third ventriculostomy (ETV) is a safe and successful procedure in the management obstructive hydrocephalus. [J Natl Inst Neurosci Bangladesh 2015;1(1): 5-7]
