In the adult it is associated with multiple pathological conditions including trigeminal neuralgia, ophthalmoplegia, hypopituitarism, intracavernous fistula, brain aneurysms and posterior circulation strokes. The latter may occur through steal phenomena or thrombosis in the anterior circulation. PTA associated vertebrobasilar hypoplasia has yet to be associated to TIA like events, however, in the reported case, that seems to be the case with reported vertigo being probably linked to vertebrobasilar insufficiency.<\/jats:p>\n              <\/jats:sec>\n              <jats:sec>\n                <jats:title>Case report<\/jats:title>\n                <jats:p>We present a case of an 82-year-old man with sudden onset neurological deficits, including left hemiparesis with crural predominance, vertical nystagmus, right internuclear ophthalmoplegia, dysarthria and dysmetria on the left arm. CT angiography disclosed basilar artery hypoplasia in the proximal two thirds and a persistent trigeminal artery. He was diagnosed with acute ischemic stroke. He was submitted to rt-PA with partial reversion of deficits.<\/jats:p>\n              <\/jats:sec>\n              <jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>The ischemic events related to PTA remain a rare cause of stroke with specific pathophysiological mechanisms and implications. They may occur through steal phenomena or thrombosis in the anterior circulation. Upon literature review, in the described case both mechanisms seem possible, however the transient episodes of vertigo could have been the first sign of vertebrobasilar insufficiency.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12883-019-1492-2","type":"journal-article","created":{"date-parts":[[2019,10,27]],"date-time":"2019-10-27T13:02:16Z","timestamp":1572181336000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Persistent trigeminal artery in a patient with posterior circulation stroke treated with rt-PA: case report"],"prefix":"10.1186","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3792-8542","authenticated-orcid":false,"given":"Axel","family":"Ferreira","sequence":"first","affiliation":[]},{"given":"Paulo S.","family":"Coelho","sequence":"additional","affiliation":[]},{"given":"V\u00edtor Tedim","family":"Cruz","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2019,10,27]]},"reference":[{"issue":"1","key":"1492_CR1","doi-asserted-by":"publisher","first-page":"5","DOI":"10.1007\/s00234-011-0995-3","volume":"55","author":"S Meckel","year":"2013","unstructured":"Meckel S, Spittau B, McAuliffe W.
