The endoscope is then advanced into the third ventricle and the floor of the third ventricle is confirmed in the midline anterior to the mammillary bodies and posterior to the infundibular recess fig.
Floor of third ventricle perforation.
Short term memory loss is another potential complication of endoscopic third ventriculostomy.
Running through the third ventricle is the interthalamic adhesion which contains thalamic.
B view of the floor of the third ventricle.
Large bleeds due to vessel injury under the third ventricle can be catastrophic but they are rare.
Transient diabetes insipidus one of its rarest complications.
Perforation of the thick floor of the third ventricle with bipolar diathermy coagulation and perforation with decq forceps when you cannot visualize the basilar artery aim towards the direction of the dorsum sellae to avoid injuring it.
From anterior to posterior the optic chiasm infundibulum tuber cinereum paired mammillary bodies are clearly seen.
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.
Endoscopic third ventriculostomy procedure.
Like other ventricles the third ventricle has a cavity an anterior wall a posterior wall a floor a roof and two lateral walls.
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 floor of the third ventricle was subsequently fenestrated in a standard fashion often with balloon dilation through the endoscope.
This procedure can cause a variety of complications reported in the literature.
The third ventricle is a narrow cavity located between the two hemispheres of the diencephalon of the forebrain the third ventricle is part of a network of linked cavities cerebral ventricles in the brain that extend to form the central canal of the spinal cord the cerebral ventricles consist of the lateral ventricles third ventricle and fourth ventricle.
Etv is technically difficult in post infective hydrocephalus especially in acute phase of disease due to presence of inflammation thick and opaque floor of third ventricle 7 10 17 it is comparatively simple in chronic phase of disease there is an increased risk of hemorrhage and neurovascular injury especially in acute phase.
The scope was then removed the craniostomy plugged with gel foam and a layered closure was subsequently performed.
The basilar artery can also be seen between the mammillary arteries and must be avoided upon perforation of the third ventricular floor.
