However, there are few reports of obstructive hydrocephalus after spinal surgery for other pathologies of the craniovertebral junction (CVJ). The authors herein report a 52-year-old female with achondroplasia presenting with an 8-month history of myelopathy due to spinal cord compression at CVJ. She underwent resection of the C1 posterior arch and part of the edge of the occipital bone. A computed tomography (CT) scan obtained 1-week after the surgery revealed bilateral infratentorial fluid collection. The patient was first managed conservatively; however, on the 17th day, her consciousness level showed sudden deterioration. Emergency CT demonstrated marked hydrocephalus due to obstruction of the cerebral aqueduct. Acute obstructive hydrocephalus can occur late after decompression surgery at the CVJ, and thus should be included in the differential diagnosis of a deteriorating mental status.<\/jats:p>","DOI":"10.4103\/1793-5482.179643","type":"journal-article","created":{"date-parts":[[2016,4,5]],"date-time":"2016-04-05T07:54:44Z","timestamp":1459842884000},"page":"311-312","source":"Crossref","is-referenced-by-count":5,"title":["Acute obstructive hydrocephalus complicating decompression surgery of the craniovertebral junction"],"prefix":"10.1055","volume":"11","author":[{"given":"Junichi","family":"Ohya","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Faculty of Medicine, The University of Tokyo, Tokyo 113-8655"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hirotaka","family":"Chikuda","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Faculty of Medicine, The University of Tokyo, Tokyo 113-8655"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hirofumi","family":"Nakatomi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Faculty of Medicine, The University of Tokyo, Tokyo 113-8655"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryuji","family":"Sakamoto","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Faculty of Medicine, The University of Tokyo, Tokyo 113-8655"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nobuhito","family":"Saito","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Faculty of Medicine, The University of Tokyo, Tokyo 113-8655"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sakae","family":"Tanaka","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Faculty of Medicine, The University of Tokyo, Tokyo 113-8655"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2022,9,20]]},"reference":[{"key":"key-10.4103\/1793-5482.179643-1","unstructured":"Carey CM, Tullous MW, Walker ML.
