Floor Of Third Ventricle Perferated

The floor of the third ventricle is formed by a number of structures including the hypothalamus subthalamus mammilary bodies infundibulum pituitary stalk and the tectum of the midbrain.

Floor of third ventricle perferated.

As a general rule etv is used for obstructive rather than communicating hydrocephalus 37 38 although its use has been reported in ah. Side walls these are the lateral walls of third ventricle formed by thalamus hypothalamic groove or sulcus and hypothalamus itself. Floor and roof the floor is formed by the optic chiasma the tuber cinereum and the infundibulum the mamillary bodies the posterior perforated substance and the tegmentum of the midbrain. An endoscopic third ventriculostomy can be performed in order to release extra fluid caused by hydrocephalus.

The scope was then removed the craniostomy plugged with gel foam and a layered closure was subsequently performed. These cells produce cerebrospinal fluid. Like other ventricles the third ventricle has a cavity an anterior wall a posterior wall a floor a roof and two lateral walls. Describe the location and boundaries of third ventricle.

The floor of the third ventricle was then perforated and dilated with a four french fogarty catheter bipolar cautery and irrigation were used as necessary for hemostasis. The floor of the third ventricle is formed by hypothalamic structures and this can be opened surgically between the mamillary bodies and the pituitary gland in a procedure called an endoscopic third ventriculostomy. Floor it is actually the floor of third ventricle it extends across optic chiasma tuber cinerium infundibulum and mamillary bodies to posterior perforated substance 6. Its upper part assists in forming the floor of the third ventricle.

A post operative mri shows very small residual under the corpus callosum adherent to the roof of the left lateral ventricle. This procedure can cause a variety of complications reported in the literature. Anterior wall is formed from above downwards by. The floor of third ventricle is perforated anterior to the halfway point between infundibular recess and mamillary bodies and a balloon dilatation technique is the most used during the ventriculostomy.

37 while in theory this is a simple. Patients were stratified into three groups. It is a cavity within diencephalon it is a midline slit like cavity situated between the two thalami and the part of hypothalamus. The third ventricle has.

The posterior perforated substance is the depressed area between the crura is termed the interpeduncular fossa and consists of a layer of gray matter which is pierced by small apertures for the transmission of blood vessels. Its lower part lies on the ventral aspect of the medial portions of the tegmenta and contains a nucleus named the interpeduncular ganglion.
