UNLABELLED Transsphenoidal surgery is the most commonly used surgical procedure to handle the hypophyseal region, sometimes associated with oronasal complications. MATERIAL AND METHODS/AIM To evaluate prospectively (specific questionnaire, clinical evaluation) undiagnosed chronic oronasal complications in patients submitted to conventional transsphenoidal adenomectomy surgery, operated at dif...

BACKGROUND Postoperative cerebrospinal fluid (CSF) fistula is the most serious complication after transsphenoidal surgery. OBJECTIVE To analyze the incidence of CSF fistula after endoscopic transsphenoidal surgery for tumor removal in sellar region; to discuss associated factors and methods used for sellar closure. METHOD Retrospective study of 67 patients (73 surgeries) operated via transs...

Uncontrolled cerebrospinal fluid (CSF) leakage after transsphenoidal surgery (TSS) for pituitary adenoma can lead to meningitis. Intracranial mycotic pseudoaneurysm is a rare complication in central nervous system infection. Large single pseudoaneurysm is more uncommon. Most mycotic aneurysms occur due to endocarditis. The present patient had no heart problem and was infected by CSF leakage aft...

Internal carotid artery (ICA) injury following transsphenoidal surgery is a rare but potentially fatal complication. Usually, endovascular occlusion of the ICA or stent graft placement is the treatment of these vascular complications described in literature. We present a case of ICA perforation during transsphenoidal surgery in a patient with limited collateral cerebral blood flow and with ecta...

The aim of this study was to elucidate the risk factors for cerebrospinal fluid (CSF) rhinorrhoea following transsphenoidal surgery and discuss its prevention and treatments. We retrospectively reviewed 474 consecutive cases of pituitary adenoma treated with 485 transsphenoidal surgical procedures from January 2008 to December 2011 in our department. We analysed the incidence of intra- and post...

Cerebrospinal fluid (CSF) leak is the most commonly encountered perioperative complication in transsphenoidal surgery for pituitary lesions. Direct closure with a combination of autologous fat, local bone, and/or synthetic grafts remains the standard of care for leaks encountered at the time of surgery as well as postoperatively. The development of the vascularized nasoseptal flap as a closure ...

The coexistence of cerebral aneurysm and pituitary adenoma has been described previously. Most of such cases harbor functional tumors and anterior circulation aneurysms, with very rare cases of posterior circulation aneurysms. In this report, we present a case of subarachnoidal hemorrhage due to rupture of an undetected basilar apex aneurysm during microscopic transsphenoidal surgery for a nonf...

Transsphenoidal surgery produces changes in the parana sal sinuses and sella that should be familiar to radiologists in view of the frequency of this type of surgery. Some of these changes, such as soft-tissue-density debris in the sinuses, are transient. Fat and other packing material identifiable in the sinuses and sella after surgery is permanent. The procedure is associated with a variety o...

Objective: This study aims to analyze the complications of endoscopic transsphenoidal surgery for pituitary neoplasms. Methods: 326 patients who underwent neuroendoscopic endonasal transsphenoidal surgery at the neurosurgery department of the First Affiliated Hospital of Chongqing Medical University from July 2012 to July 2015 were enrolled in this retrospective analysis. Results: Among the 326...
