Intraoperative MRI in trans-sphenoidal surgery using frameless stereotaxis

Intraoperative MRI and Image-guided Frameless Neuronavigation

Neurosurgeons have long used various image-guided systems, such as fluoroscopy, ultrasound, and threedimensional (3-D) stereotaxy in an attempt to more accurately localize intracranial targets (34). The development of advanced neuroimaging techniques over the years has provided the neurosurgeon with increasingly more accurate and precise tools to aid in the microsurgical treatment of intracrani...

Emergency reconstructive endovascular management of intraoperative complications involving the internal carotid artery from trans-sphenoidal surgery.

PURPOSE To report our experience with intraoperative complications involving the internal carotid artery (ICA) during trans-sphenoidal surgery and their outcome with reconstructive endovascular management. METHODS A retrospective review was conducted of patients with an ICA injury related to trans-sphenoidal surgery from 2000 to 2012. Demographic data, clinical charts, indications for treatme...

The History of Trans-sphenoidal Surgery for Pituitary Tumours

Frameless intraoperative navigation and referencing in maxillofacial surgery - advances and limitations

Computer-assisted surgery has found frequent application in oncological and reconstructive surgery of the maxillofacial region. For those indications, important features are a high degree of mobility of the patient’s head during navigation for a comfortable surgical handling and a high precision of the non-invasive referencing for a good surgical outcome. Common methods of reference-giving, suc...

Angio-oedema after trans-sphenoidal surgery in a patient with Cushing's disease.

Cushing’s disease is bilateral adrenocortical hyperplasia secondary to excessive secretion of ACTH by the pituitary gland. Angio-oedema is due to oedema in the deeper subcutaneous and submucosal tissues. We report a patient with acquired angio-oedema which developed after transsphenoidal surgery for Cushing’s disease (CD). A 50-year-old woman admitted to the endocrinology department with a two-...
