These Silastic catheters are elastic and durable; however, catheter-associated malfunctions are well reported in the literature. Fractured catheters are managed with some variability, but entirely intradural retained fragments are often managed conservatively with observation.<\/jats:p>\n<jats:p>The authors describe a case of a 70-year-old man with an implanted intrathecal morphine pump for failed back surgery syndrome who presented to an outside hospital with a history of headache, neck pain, nausea, and photophobia of 3 days' duration. He also described mild weakness and intermittent numbness of both legs. Unenhanced head CT demonstrated subarachnoid hemorrhage (SAH). A right C-5 hemilaminectomy was performed.<\/jats:p>\n<jats:p>This case is unique in that there was no indication that the lumbar intrathecal catheter had fractured prior to the patient's presentation with SAH. This case demonstrates that intrathecal catheter fragments are mobile and can precipitate intracranial morbidity. Extrication of known fragments is safe and should be attempted to prevent further neurosurgical morbidity.<\/jats:p>","DOI":"10.3171\/2014.9.spine147","type":"journal-article","created":{"date-parts":[[2014,10,31]],"date-time":"2014-10-31T14:02:53Z","timestamp":1414764173000},"page":"47-51","source":"Crossref","is-referenced-by-count":8,"title":["Migrating lumbar intrathecal catheter fragment associated with intracranial subarachnoid hemorrhage"],"prefix":"10.3171","volume":"22","author":[{"given":"Luke","family":"Hnenny","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hatem A.","family":"Sabry","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey S.","family":"Raskin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jesse J.","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neil E.","family":"Roundy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aclan","family":"Dogan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-spine147","series-title":"Pain","doi-asserted-by":"publisher","first-page":"274","DOI":"10.1016\/j.pain.2005.08.005","article-title":"Intraparenchymal migration of an intrathecal catheter three years after implantation","volume":"118","author":"Albrecht","year":"2005"},{"key":"b2-spine147","series-title":"South Med J","doi-asserted-by":"publisher","first-page":"634","DOI":"10.1097\/00007611-199606000-00019","article-title":"Cranial migration of a lumboperitoneal shunt catheter","volume":"89","author":"Alleyne","year":"1996"},{"key":"b3-spine147","series-title":"Clin Neurol Neurosurg","doi-asserted-by":"publisher","first-page":"203","DOI":"10.1016\/S0303-8467(99)00036-0","article-title":"Intracranial dislocation of a lumbo-peritoneal shunt-catheter: case report and review of the literature","volume":"101","author":"Anthogalidis","year":"1999"},{"key":"b4-spine147","series-title":"Anesth Analg","doi-asserted-by":"publisher","first-page":"46","DOI":"10.1213\/ANE.0b013e3181ddddd6","article-title":"Lumbar cerebrospinal fluid drainage for thoracoabdominal aortic surgery: rationale and practical considerations for management","volume":"111","author":"Fedorow","year":"2010"},{"key":"b5-spine147","series-title":"Spinal Cord","doi-asserted-by":"publisher","first-page":"639","DOI":"10.1038\/sc.2008.24","article-title":"Device-related complications of long-term intrathecal drug therapy via implanted pumps","volume":"46","author":"Fl\u00fcckiger","year":"2008"},{"key":"b6-spine147","series-title":"J Pain Symptom Manage","doi-asserted-by":"publisher","first-page":"209","DOI":"10.1016\/S0885-3924(99)00153-0","article-title":"A prospective study of catheterrelated complications of intrathecal drug delivery systems","volume":"19","author":"Follett","year":"2000"},{"key":"b7-spine147","series-title":"J Neurosurg Spine","doi-asserted-by":"publisher","first-page":"641","DOI":"10.3171\/2011.8.SPINE11387","article-title":"Subarachnoid hemorrhage due to retained lumbar drain.
