Floor of third ventricle perferated.

37 while in theory this is a simple. This video shows how the floor of the third ventricle is perforated. It is a cavity within diencephalon it is a midline slit like cavity situated between the two thalami and the part of hypothalamus. An endoscopic third ventriculostomy can be performed in order to release extra fluid caused by hydrocephalus.

The third ventricle has. A post operative mri shows very small residual under the corpus callosum adherent to the roof of the left lateral ventricle. 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. Describe the location and boundaries of third ventricle.

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 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. The lateral walls of the third ventricle are formed by the walls of the left and right thalamus. This procedure can cause a variety of complications reported in the literature.

Anterior wall is formed from above downwards by. 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. 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.

39 40 the etv procedure consists of advancing a fiberoptic endoscope into the lateral ventricle through the foramen of monro into the third ventricle so that under direct visualization the membranous floor of the third ventricle can be perforated bluntly followed by enlargement of the fenestration using a balloon. The scope was then removed the craniostomy plugged with gel foam and a layered closure was subsequently performed. Side walls these are the lateral walls of third ventricle formed by thalamus hypothalamic groove or sulcus and hypothalamus itself. 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.

Like other ventricles the third ventricle has a cavity an anterior wall a posterior wall a floor a roof and two lateral walls. Its lower part lies on the ventral aspect of the medial portions of the tegmenta and contains a nucleus named the interpeduncular ganglion.
