With increased awareness and advancements in imaging modalities, they are now more frequently detected. However, concerns regarding their suboptimal treatment and lack of proper analysis still exist. We are hereby reporting our experience of treating this entity in a small cohort.<\/jats:p><jats:p>\n               Materials and Methods\u2003It is a retrospective study of all the cases of SAH resulting from rupture of BAPA, which were treated by the same surgical team. Demographic data, treatment characteristics, and follow-up data of our cases along with published literature were studied.<\/jats:p><jats:p>\n               Results\u2003Our cohort comprised of five patients (mean age 55 years). Three cases were treated with flow diverter alone and the rest underwent flow diverter and overlapping stent placement. Initial diagnostic cerebral angiography (digital subtraction angiography) was negative in three of them. There was one mortality and favorable outcome was encountered in the remaining cases. All of them demonstrated complete occlusion of the aneurysm in follow-up.<\/jats:p><jats:p>\n               Conclusion\u2003Following treatment, all the cases demonstrated complete angiographic occlusion of the aneurysm. In available literature, studies have small sample sizes. Future randomized studies in a larger cohort and proper reporting and analysis of outcomes will help us formulating a treatment protocol for BAPA.<\/jats:p>","DOI":"10.1055\/s-0045-1804999","type":"journal-article","created":{"date-parts":[[2025,3,6]],"date-time":"2025-03-06T19:28:31Z","timestamp":1741289311000},"page":"322-329","source":"Crossref","is-referenced-by-count":0,"title":["Ruptured Basilar Artery Perforator Aneurysm: Nightmare of a Treating Neurosurgeon"],"prefix":"10.1055","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9827-7937","authenticated-orcid":false,"given":"Pragyan","family":"Sarma","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-3285-4560","authenticated-orcid":false,"given":"Atul","family":"Agrawal","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1110-9469","authenticated-orcid":false,"given":"Amit Kumar","family":"Sharma","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2025,3,6]]},"reference":[{"issue":"02","key":"ref1","doi-asserted-by":"crossref","first-page":"393","DOI":"10.1097\/00006123-199608000-00034","article-title":"Distal basilar perforator artery aneurysm: case report","volume":"39","author":"Z Ghogawala","year":"1996","journal-title":"Neurosurgery"},{"issue":"04","key":"ref2","doi-asserted-by":"crossref","first-page":"412","DOI":"10.1136\/neurintsurg-2019-015311","article-title":"A systematic review of non-trunk basilar perforator aneurysms: is it worth chasing the small fish?","volume":"12","author":"M F Granja","year":"2020","journal-title":"J Neurointerv Surg"},{"issue":"05","key":"ref3","doi-asserted-by":"crossref","first-page":"263","DOI":"10.1016\/j.neuchi.2016.03.003","article-title":"A dissecting aneurysm of a basilar perforating artery","volume":"62","author":"R Aboukais","year":"2016","journal-title":"Neurochirurgie"},{"issue":"07","key":"ref4","doi-asserted-by":"crossref","first-page":"669","DOI":"10.1136\/neurintsurg-2016-012407","article-title":"Basilar artery perforator aneurysms (BAPAs): review of the literature and classification","volume":"9","author":"S R Satti","year":"2017","journal-title":"J Neurointerv Surg"},{"issue":"03","key":"ref5","doi-asserted-by":"crossref","first-page":"783","DOI":"10.1007\/s00062-021-01133-y","article-title":"Flow diverter treatment of ruptured basilar artery perforator aneurysms : a multicenter experience","volume":"32","author":"S Elsheikh","year":"2022","journal-title":"Clin Neuroradiol"},{"issue":"05","key":"ref6","doi-asserted-by":"crossref","first-page":"639","DOI":"10.1007\/s00234-020-02618-2","article-title":"Comparison between stenting and conservative management of posterior circulation perforator aneurysms: systematic review and case series","volume":"63","author":"D Gardijan","year":"2021","journal-title":"Neuroradiology"},{"key":"ref7","doi-asserted-by":"crossref","first-page":"366","DOI":"10.1016\/j.wneu.2016.10.038","article-title":"A dissecting aneurysm of a basilar perforating artery.
