Contact aspiration has proven to be a valuable technique in treating ischemic strokes by removing the intraluminal thrombus causing cerebral perfusion deficits and neurological symptoms. The authors present a case of the removal of a foreign body from the vasculature via contact aspiration, which had embolized in a delayed fashion after aortic valve replacement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>OBSERVATIONS<\/jats:title>\n                    <jats:p>A 54-year-old male developed intermittent left-sided weakness 8 days after aortic valve replacement. A head computed tomography scan showed a metallic foreign body within the origin of the M2 superior division of the middle cerebral artery suspected to be a migrated Cor-Knot fastener.<\/jats:p>\n                    <jats:p>During angiography, the foreign body was repositioned and removed via contact aspiration. Postprocedurally, magnetic resonance imaging scans showed a small area of diffusion restriction in the right basal ganglia. The patient was neurologically intact and was discharged on postprocedure day 2 without further neurological sequelae.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>Contact aspiration is a safe and effective technique to remove foreign bodies from the intracranial circulation; however, it requires a quality interface between the aspiration catheter and the foreign body throughout the aspiration process.<\/jats:p>\n                    <jats:p>\n                      <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/thejns.org\/doi\/10.3171\/CASE24376\">https:\/\/thejns.org\/doi\/10.3171\/CASE24376<\/jats:ext-link>\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case24376","type":"journal-article","created":{"date-parts":[[2024,11,18]],"date-time":"2024-11-18T01:45:00Z","timestamp":1731894300000},"source":"Crossref","is-referenced-by-count":1,"title":["Endovascular removal of a symptomatic intracranial foreign body via contact aspiration: illustrative case"],"prefix":"10.3171","volume":"8","author":[{"given":"Jared M.","family":"Robichaux","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery, Louisiana State University Health Sciences Center, New Orleans, Louisiana"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sarah E.","family":"Lawhon","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery, Louisiana State University Health Sciences Center, New Orleans, Louisiana"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taylor W.","family":"Girolamo","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery, Louisiana State University Health Sciences Center, New Orleans, Louisiana"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kapland Q.","family":"Owens","sequence":"additional","affiliation":[{"name":"Departments of Surgery, Louisiana State University Health Sciences Center, New Orleans, Louisiana"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucido L.","family":"Ponce Mejia","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery, Louisiana State University Health Sciences Center, New Orleans, Louisiana"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"issue":"4","key":"bib1","series-title":"J Neurointerv Surg","first-page":"378","article-title":"Intraoperative vascular complications during 2278 cerebral endovascular procedures with multimodality IONM: relationship between signal change, complication, intervention and postoperative outcome","volume":"13","author":"Wilent","year":"2021","unstructured":"Wilent WBBelyakina OKorsgaard E, et al.
