All eight patients (100%) who underwent combined surgery had tumors with multilobulations, extensions, and encasement of the vessels in the circle of Willis (COW). Of 72 patients who underwent ETSS alone, 21 (29.1%) had a multilobulated tumor, 26 (36.2%) tumors had anterior\/lateral extensions, and 12 (16.6%) had encasement of the COW. The mean TTV, TEV, and SET for the combined surgery group were significantly higher than those in the ETSS group. None of the patients who underwent combined surgery suffered postoperative residual tumor apoplexy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Patients with GPAs in whom there are significant lateral intradural or subfrontal tumor extensions should be considered for combined surgery at the same sitting to avoid devastating postoperative apoplexy in the residual tumor, which can occur when ETSS alone is performed.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/0028-3886.378658","type":"journal-article","created":{"date-parts":[[2023,8,24]],"date-time":"2023-08-24T04:18:06Z","timestamp":1692850686000},"page":"439-446","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Preventing Postoperative Apoplexy in Giant Pituitary Adenomas using Combined Trans-Sphenoidal and Cranial Surgery"],"prefix":"10.4103","volume":"71","author":[{"given":"Manish","family":"Baldia","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vedantam","family":"Rajshekhar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-8-20240907","doi-asserted-by":"crossref","first-page":"133","DOI":"10.1080\/02688690220131723","article-title":"Giant pituitary adenomas: Clinical characteristics and surgical results","volume":"16","author":"Garibi","year":"2002","journal-title":"Br J Neurosurg"},{"key":"R2-8-20240907","doi-asserted-by":"crossref","first-page":"621","DOI":"10.3171\/2012.11.JNS121190","article-title":"Endoscopic endonasal surgery for giant pituitary adenomas: Advantages and limitations","volume":"118","author":"Koutourousiou","year":"2013","journal-title":"J Neurosurg"},{"key":"R3-8-20240907","doi-asserted-by":"crossref","first-page":"993","DOI":"10.1227\/01.NEU.0000255459.14764.BA","article-title":"Surgical treatment of giant pituitary adenomas: Strategies and results in a series of 95 consecutive patients","volume":"60","author":"Mortini","year":"2007","journal-title":"Neurosurgery"},{"key":"R4-8-20240907","doi-asserted-by":"crossref","first-page":"326","DOI":"10.4103\/0028-3886.16933","article-title":"Post operative'pituitary apoplexy'in giant pituitary adenomas: A series of cases","volume":"53","author":"Ahmad","year":"2005","journal-title":"Neurol India"},{"key":"R5-8-20240907","doi-asserted-by":"crossref","first-page":"37","DOI":"10.1080\/02688699550041728","article-title":"Fatal postoperative'pituitary apoplexy': Its cause and management","volume":"9","author":"Goel","year":"1995","journal-title":"Br J Neurosurg"},{"key":"R6-8-20240907","doi-asserted-by":"crossref","first-page":"59","DOI":"10.3109\/02688697.2011.591947","article-title":"Post operative pituitary apoplexy: Preoperative considerations toward preventing nightmare","volume":"26","author":"Kurwale","year":"2012","journal-title":"Br J Neurosurg"},{"key":"R7-8-20240907","doi-asserted-by":"crossref","first-page":"380","DOI":"10.1016\/S0090-3019(02)00705-X","article-title":"Combined transsphenoidal and pterional craniotomy approach to giant pituitary tumors","volume":"57","author":"Alleyne","year":"2002","journal-title":"Surg Neurol"},{"key":"R8-8-20240907","doi-asserted-by":"crossref","first-page":"1401","DOI":"10.1007\/s00701-011-1029-y","article-title":"Combined simultaneous transcranial and transsphenoidal resection of large-to-giant pituitary adenomas","volume":"153","author":"Leung","year":"2011","journal-title":"Acta Neurochir (Wien"},{"key":"R9-8-20240907","first-page":"485","article-title":"Combined supra-infrasellar approach for large pituitary tumors","volume":"14","author":"Loyo","year":"1984","journal-title":"Neurosurgery"},{"key":"R10-8-20240907","doi-asserted-by":"crossref","first-page":"21","DOI":"10.1007\/s00701-006-1044-6","article-title":"Objective criteria for successful transsphenoidal removal of suprasellar nonfunctioning pituitary adenomas.
