Here, we analyzed the position of LPS shunts placed without portable fluoroscopy in 72 patients, a subset of whom developed postoperative radiculopathy.<\/jats:p>\n<\/jats:sec>\n\nMethods: <\/jats:title>\nWe retrospectively analyzed how frequently 72 consecutive NPH patients experienced radiculopathy following LPS catheter placement performed without intraoperative fluoroscopy.<\/jats:p>\n<\/jats:sec>\n\nResults: <\/jats:title>\nThe rate of incorrect catheter placement was 15.3% (11\/72 cases). We observed that is, downward placement in 6.9% (5\/72 cases), hyperflexion in 6.9% (5\/72 cases), and subcutaneous migration in 1.4% (1\/72 cases) patients. One patient with initial correct LPS placement developed radicular pain 5-day postoperatively attributed to 1-cm of catheter movement; they recovered simply by utilizing oral analgesics for 1-month duration.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nLPS insertion without fluoroscopic guidance resulted in a 15.3% risk of spinal catheter displacement. We suggest, therefore, that intraoperative imaging guidance be utilized for the placement of LPS in patients with NPH and\/or for other pathology to avoid the 15.3% risk of postoperative radiculopathy.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_791_2022","type":"journal-article","created":{"date-parts":[[2022,9,23]],"date-time":"2022-09-23T08:58:41Z","timestamp":1663923521000},"page":"437","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Incidence of radiculopathy following lumboperitoneal shunt placement without fluoroscopy for normal pressure hydrocephalus"],"prefix":"10.25259","volume":"13","author":[{"given":"Tatsuya","family":"Tanaka","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, International University of Health and Welfare, School of Medicine, Narita, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hirofumi","family":"Goto","sequence":"additional","affiliation":[{"name":"Department of Neurology, Imari Arita Kyoritsu Hospital, Arita, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuaki","family":"Momozaki","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Imari Arita Kyoritsu Hospital, Arita, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eiichiro","family":"Honda","sequence":"additional","affiliation":[{"name":"Department of Neurospinal Surgery, Shiroishi Kyoritsu Hospital, Shiroishi, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2022,9,23]]},"reference":[{"key":"10.25259\/SNI_791_2022\/ref-1","doi-asserted-by":"crossref","first-page":"998","DOI":"10.1227\/00006123-199006000-00013","article-title":"Lumboperitoneal shunt: Clinical applications, complications, and comparison with ventriculoperitoneal shunt","volume":"26","author":"Aoki","year":"1990","journal-title":"Neurosurgery"},{"key":"10.25259\/SNI_791_2022\/ref-2","doi-asserted-by":"crossref","first-page":"427","DOI":"10.3171\/jns.1971.35.4.0427","article-title":"Lumboperitoneal shunts.
