A 34-year-old woman underwent satisfactory treatment of a ruptured giant basilar bifurcation aneurysm by BA ligation (Drake tourniquet) in 1985. She presented 25 years later with a new aneurysm in the left PCA, successfully treated by coil embolization. To the authors\u2019 knowledge, this is the first case of de novo aneurysm formation on a PCA, and the first de novo aneurysm reported as a complication of BA ligation therapy by Drake tourniquet. Long-term follow-up is necessary in patients with treated cerebral aneurysms, particularly those occurring in young patients, those with multiple aneurysms, those with complex posterior circulation aneurysms, and those undergoing flow diversion or flow-altering therapies.<\/jats:p>","DOI":"10.3171\/2016.11.jns161740","type":"journal-article","created":{"date-parts":[[2017,5,5]],"date-time":"2017-05-05T13:58:50Z","timestamp":1493992730000},"page":"1028-1031","source":"Crossref","is-referenced-by-count":4,"title":["De novo giant posterior cerebral artery aneurysm developing 25 years after basilar bifurcation aneurysm treatment using a Drake tourniquet: case report and implications for aneurysm follow-up"],"prefix":"10.3171","volume":"128","author":[{"given":"Rafael","family":"Martinez-Perez","sequence":"first","affiliation":[{"name":"Division of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David M.","family":"Pelz","sequence":"additional","affiliation":[{"name":"Medical Imaging, Department of Clinical Neurological Sciences, University of Western Ontario, London, Ontario, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen P.","family":"Lownie","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"785","DOI":"10.1227\/NEU.0b013e318265a416","article-title":"Safety and efficacy of endovascular treatment of basilar tip aneurysms by coiling with and without stent assistance: a review of 235 cases","volume":"71","author":"Chalouhi N","year":"2012","unstructured":"Chalouhi N, Jabbour P, Gonzalez LF, Dumont AS, Rosenwasser R, Starke RM, : Safety and efficacy of endovascular treatment of basilar tip aneurysms by coiling with and without stent assistance: a review of 235 cases.
