CT showed subarachnoid hemorrhage and digital subtraction angiogram demonstrated a right-side posterior inferior cerebellar artery (PICA) aneurysm. Given the medial and ventral position of the aneurysm, deep to the lower cranial nerves, which obviated distal control from an open approach, and the absence of an endovascular option able to reliably preserve the PICA, an endonasal approach was offered. A far medial approach was performed, and the aneurysm was successfully clipped. The patient developed a postoperative CSF leak with persistent posthemorrhagic hydrocephalus treated with reexploration and an eventual ventriculoperitoneal shunt. The patient was discharged without neurological deficits.<\/jats:p>\n \n The video can be found here:\n https:\/\/youtu.be\/_9hsM2CaMow<\/jats:ext-link>\n .\n <\/jats:p>","DOI":"10.3171\/2020.4.focusvid.19901","type":"journal-article","created":{"date-parts":[[2020,4,25]],"date-time":"2020-04-25T22:01:18Z","timestamp":1587852078000},"page":"V14","source":"Crossref","is-referenced-by-count":1,"title":["Endoscopic endonasal approach for clipping of a PICA aneurysm"],"prefix":"10.3171","volume":"2","author":[{"given":"Ezequiel","family":"Goldschmidt","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philippe","family":"Lavigne","sequence":"additional","affiliation":[{"name":"Otolaryngology, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carl","family":"Snyderman","sequence":"additional","affiliation":[{"name":"Otolaryngology, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul A.","family":"Gardner","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"131","DOI":"10.3171\/2018.5.JNS18595","article-title":"The medial wall of the cavernous sinus.
