She underwent flow diversion therapy for both aneurysms with a PED, but the distal shortening of the PED after deployment led to the exposure of the anterior choroidal artery aneurysm. Follow-up angiography revealed complete obliteration of the posterior communicating artery aneurysm, but the anterior choroidal artery aneurysm remained. Three years after the endovascular surgery, the patient experienced a subarachnoid hemorrhage due to the rupture of the anterior choroidal artery aneurysm. Retrospective analysis of angiographic images revealed a change in the vascular geometry surrounding the ruptured aneurysm after PED deployment; this was further accompanied by an increase in the flow velocity inside the aneurysm.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>Because PED use might induce the adverse effects on the adjacent uncovered aneurysm by changing the vascular geometry and hemodynamic stress, a cautious therapeutic strategy, such as proper placement of the stent and using a longer and appropriate-sized PED, should be chosen when deploying the PED.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case21651","type":"journal-article","created":{"date-parts":[[2022,4,4]],"date-time":"2022-04-04T03:08:50Z","timestamp":1649041730000},"source":"Crossref","is-referenced-by-count":0,"title":["Rupture of an adjacent cerebral aneurysm following the deployment of a Pipeline embolization device: illustrative case"],"prefix":"10.3171","volume":"3","author":[{"given":"Atsushi","family":"Nakayashiki","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, National Hospital Organization Sendai Medical Center, Sendai, Miyagi, Japan; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyuki","family":"Sakata","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, National Hospital Organization Sendai Medical Center, Sendai, Miyagi, Japan; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masayuki","family":"Ezura","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, National Hospital Organization Sendai Medical Center, Sendai, Miyagi, Japan; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hidenori","family":"Endo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, National Hospital Organization Sendai Medical Center, Sendai, Miyagi, Japan; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Inoue","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, National Hospital Organization Sendai Medical Center, Sendai, Miyagi, Japan; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Atsushi","family":"Saito","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, National Hospital Organization Sendai Medical Center, Sendai, Miyagi, Japan; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Teiji","family":"Tominaga","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Tohoku University Graduate School of Medicine, Sendai, Miyagi, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Neurointerv Surg","doi-asserted-by":"publisher","first-page":"i9","DOI":"10.1136\/jnis.2009.000083.rep","article-title":"Curative cerebrovascular reconstruction with the Pipeline embolization device: the emergence of definitive endovascular therapy for intracranial aneurysms","volume":"10","author":"Fiorella D","year":"2018","unstructured":"Fiorella D, Lylyk P, Szikora I,  Curative cerebrovascular reconstruction with the Pipeline embolization device: the emergence of definitive endovascular therapy for intracranial aneurysms.
