BHS is a rare condition that can result from a variety of factors, including abnormal bone compression and vertebral instability. So far, there have been no reports in which both vertebral instability and osteophytes compress the VA at different sites, leading to stroke. Herein, we present a rare case of stroke attributed to BHS involving thrombosis formation due to osteophyte compression at C3\/4 and VA occlusion due to vertebral instability at the C4\/5 overlapped. A 72-year-old male presented with rotational vertigo and vomiting associated with a cerebellar infarction. Digital subtraction angiography revealed severe stenosis of the left VA with an intra-arterial thrombus. Percutaneous transluminal angioplasty improved the stenosis; however, intravascular ultrasound revealed compression of the VA by osteophytes at C3\/4. Additionally, left VA occlusion at C4\/5 was confirmed because of vertebral instability. The osteophyte was removed via the anterolateral approach, and the VA was decompressed. The patient's postoperative course was uneventful, with no recurrence for more than 2 years. BHS can occur in the lower cervical spine when vertebral instability coincides with intimal arterial damage caused by osteophytes at other sites.<\/jats:p>","DOI":"10.1055\/s-0044-1792160","type":"journal-article","created":{"date-parts":[[2024,11,5]],"date-time":"2024-11-05T01:15:41Z","timestamp":1730769341000},"page":"174-178","source":"Crossref","is-referenced-by-count":0,"title":["Bow\u2013Hunter Syndrome Due to Tandem Lesions; A Case Report"],"prefix":"10.1055","volume":"20","author":[{"given":"Shigeomi","family":"Yokoya","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Saiseikai Shiga Hospital, Imperial Gift Foundation Inc., Ritto, Shiga, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Nakauchi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Kanto Central Hospital of the Mutual Aid Association of Public School Teachers, Setagaya, Tokyo, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hidesato","family":"Takezawa","sequence":"additional","affiliation":[{"name":"Department of Neurology, Saiseikai Shiga Hospital, Imperial Gift Foundation Inc., Ritto, Shiga, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2024,11,4]]},"reference":[{"issue":"03","key":"ref1","doi-asserted-by":"crossref","first-page":"259","DOI":"10.1227\/00006123-197805000-00013","article-title":"Bow Hunter's stroke","volume":"2","author":"B F Sorensen","year":"1978","journal-title":"Neurosurgery"},{"issue":"06","key":"ref2","doi-asserted-by":"crossref","first-page":"625","DOI":"10.1016\/j.surneu.2005.08.016","article-title":"Rotational vertebral artery insufficiency resulting from cervical spondylosis: case report and review of the literature","volume":"65","author":"K R Bulsara","year":"2006","journal-title":"Surg Neurol"},{"issue":"06","key":"ref3","doi-asserted-by":"crossref","first-page":"1031","DOI":"10.3171\/jns.1997.86.6.1031","article-title":"Rotational occlusion of the vertebral artery caused by transverse process hyperrotation and unilateral apophyseal joint subluxation.
