Because of the deep location and a propensity for nonsaccular morphology, aneurysm trapping or endovascular occlusion of the parent artery are the usual treatment options, which are associated with varying risks of ischemic complications. The authors report on a 60-year-old woman who had a 3.5-mm unruptured aneurysm in the lateral pontomesencephalic segment of the SCA with a significant interval growth to 8 mm. Direct surgical intervention comprising trapping of the aneurysm through a subtemporal approach and intradural anterior petrosectomy combined with revascularization of the distal SCA using the superficial temporal artery (STA) was performed. This approach provided sufficient space for the bypass instruments to be introduced into the deep surgical field at a more favorable angle to enhance microscopic visualization of the anastomosis with minimal retraction of the temporal lobe. The patient was discharged with no neurological deficit. Preservation of the blood flow in the distal SCA should be attempted to minimize the risk of ischemic injury, particularly when the aneurysms arise in the anterior or lateral segment of the SCA. The authors demonstrate the safety and effectiveness of the intradural anterior petrosectomy for STA-SCA bypass along with a relevant anatomical study.<\/jats:p>","DOI":"10.3171\/2018.11.focus18432","type":"journal-article","created":{"date-parts":[[2019,2,26]],"date-time":"2019-02-26T20:59:11Z","timestamp":1551214751000},"page":"E9","source":"Crossref","is-referenced-by-count":5,"title":["Superficial temporal artery\u2013superior cerebellar artery bypass and trapping of a fusiform aneurysm using intradural anterior petrosectomy: technical case report and anatomical study"],"prefix":"10.3171","volume":"46","author":[{"given":"Soichi","family":"Oya","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Saitama Medical Center; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masahiro","family":"Indo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Saitama Medical Center; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masabumi","family":"Nagashima","sequence":"additional","affiliation":[{"name":"Department of Anatomy, Saitama Medical University, Saitama, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toru","family":"Matsui","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Saitama Medical Center; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Clin Imaging Sci","doi-asserted-by":"publisher","first-page":"47","DOI":"10.4103\/2156-7514.99181","article-title":"Endovascular management of fusiform superior cerebellar artery aneurysms: a series of three cases with review of literature","volume":"2","author":"Alurkar A","year":"2012","unstructured":"Alurkar A, Karanam LSP, Nayak S, Oak S: Endovascular management of fusiform superior cerebellar artery aneurysms: a series of three cases with review of literature.
