AIM Postoperative cerebrospinal fluid (CSF) leak following endoscopic endonasal transsphenoidal surgery (EETS) is associated with increased morbidity and mortality. This prospective study is the first evaluation of using autologous fibrin sealant for preventing postoperative CSF leak and related complications. MATERIAL AND METHODS 200 endoscopic endonasal transsphenoidal approaches were inclu...
We report on a case of endovascular management of pseudoaneurysm of the cavernous segment of the internal carotid artery with covered stent reconstruction. A 36 years-old woman with a history of previous transsphenoidal approach for pituitary macroadenoma and false aneurysma formation was studied in a protocol that included balloon test occlusion and cerebral blood flow evaluation. An endovascu...
Pituitary adenomas are common benign tumors that may or may not produce hormones that are rarely malignant. Those that do not generate hormones are considered non-functioning or non-secretory. Non-secretory pituitary adenomas are defined as tumors of the pituitary gland that lack the characteristic of hormone hypersecretion and account for 18 to31% of all surgically treated pituitary adenomas [...
Pituitary abscesses, rare lesions, may be divided into primary and secondary types. A 26-years-old woman presented with decreasing vision, and headache. Magnetic resonance images (MRI) was suggestive of a sellar tumour. She underwent a transsphenoidal approach to the pituitary gland. After dural opening, purulent material was obtained and no tumour or other associated lesion was detected. It co...
Pituitary apoplexy followed by cerebral infarction is rare. In this report, we present a 42-year-old man who had been diagnosed of pituitary adenoma presented with a sudden onset of unconsciousness, left hemiplegia and right ptosis. Investigations revealed the development of pituitary apoplexy. The extension of tumor mass compressed the supraclinoid portion of the right internal carotid artery,...
BACKGROUND A virtual reality (VR) neurosurgical simulator with haptic feedback may provide the best model for training and perfecting surgical techniques for transsphenoidal approaches to the sella turcica and cranial base. Currently there are 2 commercially available simulators: NeuroTouch (Cranio and Endo) developed by the National Research Council of Canada in collaboration with surgeons at ...
