BACKGROUND Vascular injuries in transsphenoidal surgery for pituitary adenomas are uncommon but can result in serious disability or death. CASE DESCRIPTION A 46-year-old man, who underwent resection of a pituitary adenoma with suprasellar extension via a transsphenoidal approach, presented with massive epistaxis five days postoperatively. Angiography revealed an arteriovenous fistula (AVF) be...

Occurrence of symptomatic chronic subdural haematoma (SDH) following transsphenoidal decompression of pituitary adenoma, which needed surgical evacuation, is not reported. Author reports a case of symptomatic chronic subdural haematoma observed in a series of 480-transsphenoidal surgery. A 52-year old female underwent transsphenoidal surgery for pituitary adenoma. She developed cerebrospinal fl...

Background: Currently, transsphenoidal surgery is considered the procedure of choice for treating most sellar lesions. There are two different surgical options for performing the transsphenoidal procedure, the transseptal and the endonasal techniques. Objective: the aim of this study is to compare transseptal and endonasal approaches in endoscopic transsphenoidal surgery for pituitary tumors re...

OBJECTIVE The aim of this study was to describe the use of equine pericardium sheet (Lyomesh (®) ) as dural substitute for sellar reconstruction after endoscopic endonasal transsphenoidal surgery for the removal of pituitary adenomas. METHODS We reviewed data of patients that underwent surgery by means of an endoscopic endonasal transsphenoidal approach for the removal of pituitary adenomas o...

CONTEXT Surgery is the primary treatment of acromegaly. However, it often fails to cure the patient. New strategies that improve surgical outcome are needed. OBJECTIVE Our objective was to investigate whether 6-month preoperative treatment with octreotide improves the surgical outcome in newly diagnosed acromegalic patients. PATIENTS During a 5-yr period (1999-2004), all newly diagnosed acr...

Transsphenoidal microsurgery has been the standard approach to sellar lesions since the repopularization of the technique with modifications by Dott, Guiot, and Hardy. The endonasal transseptal transsphenoidal approach, as introduced by Hirsch, is still commonly used by pituitary surgeons to remove lesions of the sellar and parasellar region. One disadvantage of this approach is that the submuc...

OBJECTIVES/HYPOTHESIS This study aimed to determine the incidence of major complications following both primary and revision transsphenoidal pituitary surgery. Major complications included endocrinopathic, skull base, orbital, hemorrhagic and thromboembolic complications, respiratory failure, and death. Secondarily, this study aimed to examine factors associated with the occurrence of complicat...
