{"title":"CSF Rhinorrhoea after Transsphenoidal Surgery","authors":"E. Elgamal","doi":"10.5580/848","DOIUrl":"https://doi.org/10.5580/848","url":null,"abstract":"Objectives: The author investigated the incidence, risk factors, prevention and management of post-transsphenoidal cerebrospinal fluid (CSF) rhinorrhoea in 146 cases with sellar lesions. Patients and Methods: A review was conducted of 146 consecutive patients who underwent transsphenoidal (TSS) surgery for mainly pituitary adenomas, or other lesions such as craniopharyngioma, Rathk's cleft cyst, meningioma or chordoma in the sella turcica that performed between January 1995 and December 2007 in King Khalid University Hospital, Riyadh, Saudi Arabia. Results: Four CSF leaks (2.7%) developed within 7 days after TSS surgery for pituitary adenoma, two were prolactin-secreting, and the other two were non-secretory macroadenomas. One patient with Cushing syndrome developed CSF leak 30 days after TSS surgery. Intra-operative CSF leak was encountered in 31 cases (21%), and insertion of lumbar CSF drain was effective in treating them. Post-operative CSF leak occurred in none of the 31 cases using preventive lumbar CSF drainage, but observed in 4 out of 115 cases without lumbar drain (P < 0.01). Lumbar CSF drainage was also effective in the treatment of the postoperative CSF leaks; it cured 4 early CSF leaks out of 5 cases. The case with late CSF leaks needed surgical repair. Conclusion: When a CSF leak is encountered during TSS procedure, meticulous layered closure of the defect and reenforcement with tissue glue and fat graft, in addition to insertion of CSF lumbar drain, is necessary to reduce the incidence of postoperative CSF leak.","PeriodicalId":326784,"journal":{"name":"The Internet Journal of Neurosurgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129742312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: This is a report of an elderly lady with presenting with sudden backache and radiating pain to both legs with bilateral foot drop. There was no urinary or bowel involvement. Clinical examination showed a bilateral L5 radiculopathy with normal perianal sensation. Investigations excluded other causes of bilateral foot drop. MRI revealed a L4 L5 central disc prolapse causing severe canal stenosis at that level. Results: Patient underwent L4 L5 laminectomy and discectomy. At follow up a month later her bilateral foot drop had improved to normal and she was independent. Conclusion: This case highlights the fact that though very rare, L4 -L5 disc prolapse can manifest with bilateral foot drop and surgery can produce a good result.","PeriodicalId":326784,"journal":{"name":"The Internet Journal of Neurosurgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114251800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 58-year-old female was transferred with confusion, fever, headaches and visual abnormalities. She had CSF pleocytosis and a presumptive diagnosis of meningitis and was on antibiotics. CT showed a large pituitary mass 21×19×21mm, an increased density on the left of the mass compatible with hemorrhage, a moderate soft tissue density and mild inflammatory change in left sphenoid sinus, erosion of the floor of the sella on the left primarily and right deviation of the midline bony septum of the sphenoid sinus. MRI confirmed these findings. The pituitary mass was debulked. Pathology revealed scant foci of poorly preserved pituitary adenoma with extensive necrosis, active inflammation and granulation tissue. Cultures were again negative. Pituitary apoplexy is an important noninfectious entity to keep in mind beside pituitary abscess when a patient presents with fever and acute neurological, visual and endocrine manifestations.","PeriodicalId":326784,"journal":{"name":"The Internet Journal of Neurosurgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133469426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used frequency domain near infrared spectroscopy (FD-NIRS) to study brain oxygenation during DEX intravenous bolus injection. Oxyhemoglobin (OHb), deoxyhemoglobin (HHb), brain oxygen saturation (SO2) and total hemoglobin (tHb) were acquired on the frontal right and left side in 4 neurosurgery patients without cerebral pathology. Measurements were performed using a portable brain oxymeter, Oxiplex TS (ISS, Champaign, IL). Dexmedetomidine 0.2 mcg/kg was given to attenuate hypertension during the initial stages of desflurane anesthesia. During DEX administration, regional cerebral OHb decreased from 17.7 ± 6.9 Mol/L to 16.1 ± 6.3 Mol/L (p < 0.05) and SO2 from 61 ± 12 % to 58 ± 12 % (p < 0.05). HHb did not change from 10.5 ± 2.8 Mol to 10.5 ± 2.7 Mol/L. Recovery of brain oxygenation to pre-DEX levels occurred within 5 minutes. After administration of DEX, a small but consistent decrease in OHb was observed, probably mediated by a local vasoconstrictor effect. Brain oxygenation decreased transiently with DEX treatment without an increase in HHb production.","PeriodicalId":326784,"journal":{"name":"The Internet Journal of Neurosurgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129862879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
