Delayed Postoperative Hyponatremia Following Endoscopic Transsphenoidal Surgery for Non-Adenomatous Parasellar Tumors

[Endoscopic transsphenoidal pituitary surgery].

Endoscopic surgery has been performed in our Department since 1996 as assistance in micro-neurosurgical procedures. In the same way the endoscope was used in transsphenoidal pituitary surgery, but from the beginning of 2004 we started with "pure" endoscopic surgery. We present our experience with the first ninety patients to demonstrate our way of operating. Endoscopic pituitary surgery is perf...

Management of Pituitary Adenomas: Mononostril Endoscopic Transsphenoidal Surgery

Introduction: The endoscopic transsphenoidal approach for pituitary adenomas and other sellar lesions is quickly becoming the procedure of choice in their surgical management. The most common approach is binostril three-hand technique which requires a large exposure and subjects both nasal cavities to potential trauma. To reduce nasal morbidity, we employ a mononostril two-hand technique with t...

Postoperative Low-Flow Cerebrospinal Fluid Leak of Endoscopic Endonasal Transsphenoidal Surgery for Pituitary Adenoma

To assess the effectiveness of continuous lumbar drainage (LD) for management of postoperative cerebrospinal fluid leaks after endoscopic endonasal transsphenoidal approach for resection of pituitary adenoma. Three hundred eighty-four medical records of patients who were admitted to our institute during a 2.5-year period were retrospectively reviewed, 33 of them experienced low-flow cerebrospin...

Delayed postoperative pituitary apoplexy after endoscopic transsphenoidal resection of a giant pituitary macroadenoma.

Postoperative pituitary apoplexy is rare and usually occurs in the immediate postoperative period (within 12 hours) after subtotal resection of giant pituitary macroadenomas with fatal outcomes. We describe a unique patient with pituitary apoplexy occurring in a delayed fashion on the third postoperative day. Early detection and emergent endoscopic transsphenoidal exploration resulted in gross ...
