Neurological examinations were consistent with left-sided lesions between spinal cord segments C\n                    <jats:sub>1<\/jats:sub>\n                    and C\n                    <jats:sub>5<\/jats:sub>\n                    . Orthogonal radiographs of the cervical spine showed a microchip dorsoventrally oriented, partially embedded in the cervical vertebral canal. Fluoroscopy was used to localize and retrieve the foreign body from the cervical spinal cord in each case. Improvement in clinical condition and return to ambulation was observed in both cats within 48 hr of surgical removal of the implant. No significant perioperative adverse events were noted during the surgical retrieval of the microchip. Two previously reported cases of intraspinal canal microchip placement had been treated surgically by hemilaminectomy. This approach carries a risk of complications, including hemorrhage from the venous sinus, iatrogenic damage to the spinal cord, and improper identification of the surgical site, requires advanced surgical training, and typically has an extended surgical time. The use of fluoroscopy to assist intraoperative localization of a spinal canal foreign body may lessen the requirement for more invasive surgical procedures.\n                  <\/jats:p>","DOI":"10.5326\/jaaha-ms-7356","type":"journal-article","created":{"date-parts":[[2023,7,11]],"date-time":"2023-07-11T11:21:45Z","timestamp":1689074505000},"page":"193-197","source":"Crossref","is-referenced-by-count":1,"title":["Fluoroscopy-Guided Surgical Removal of a Microchip from the Spinal Canal of Two Cats"],"prefix":"10.5326","volume":"59","author":[{"given":"Justin","family":"Mergl","sequence":"first","affiliation":[{"name":"From Mississauga Oakville Veterinary Emergency and Speciality Hospital, Oakville, Ontario, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Nutt","sequence":"additional","affiliation":[{"name":"From Mississauga Oakville Veterinary Emergency and Speciality Hospital, Oakville, Ontario, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Augusto","family":"Pareja","sequence":"additional","affiliation":[{"name":"From Mississauga Oakville Veterinary Emergency and Speciality Hospital, Oakville, Ontario, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3280","reference":[{"issue":"2","key":"i1547-3317-59-4-193-b1","series-title":"J Am Vet Med Assoc","first-page":"160","article-title":"Characterization of animals with microchips entering animal shelters","volume":"235","year":"2009","unstructured":"Lord\n              LK,\n            \n            \n              Ingwersen\n              W,\n            \n            \n              Gray\n              JL,\n            \n          \n          .\n\t\t\t\t\tCharacterization of animals with microchips entering animal shelters.\n\t\t\t\t\tJ Am Vet Med Assoc2009;\n\t\t\t\t\t235(\n\t\t\t\t\t2):\n\t\t\t\t\t160\u2013\n\t\t\t\t\t7."},{"key":"i1547-3317-59-4-193-b2","unstructured":"Adverse reactions.\n          \n          British Small Animal Veterinary Association.\n\t\t\t\t\thttps:\/\/www.bsava.com\/Resources\/Veterinary-resources\/Microchipping\/Adverse-reactions.
