We report a rare case of a male in his late 30s with NF1 presenting with a left-sided hip dislocation and an unusual response to spinal anaesthesia. Spinal anaesthesia was attempted using 3\u2009mL of 0.5% hyperbaric bupivacaine (dextrose 8%), resulting in a unilateral block. Pulmonary function tests did not favour general anaesthesia; hence, an MRI was performed that showed extensive abnormalities in the spine. The next day, ultrasound-guided epidural anaesthesia at T10\u2013T11 was performed successfully with placement of an epidural catheter in situ for postoperative pain control. This is a rare phenomenon underlining the complexity of anaesthetic management in patients with NF1 and significant spinal abnormalities.<\/jats:p>","DOI":"10.1136\/bcr-2024-263362","type":"journal-article","created":{"date-parts":[[2025,7,22]],"date-time":"2025-07-22T05:10:16Z","timestamp":1753161016000},"page":"e263362","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Successful ultrasound-guided epidural anaesthesia following failed spinal anaesthesia in a patient with neurofibromatosis 1"],"prefix":"10.1136","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2093-296X","authenticated-orcid":false,"given":"Atul","family":"Aman","sequence":"first","affiliation":[{"name":"Trauma and Emergency Medicine, All India Institute of Medical Sciences Kalyani, Kalyani, West Bengal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Debanjan","family":"Nandi","sequence":"additional","affiliation":[{"name":"Radiodiagnosis, All India Institute of Medical Sciences Kalyani, Kalyani, West Bengal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ravi","family":"Anand","sequence":"additional","affiliation":[{"name":"Trauma and Emergency Medicine, All India Institute of Medical Sciences Kalyani, Kalyani, West Bengal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sathiyaraj","family":"G","sequence":"additional","affiliation":[{"name":"Anaesthesiology, All India Institute of Medical Sciences Kalyani, Kalyani, West Bengal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jitendra","family":"Kumar","sequence":"additional","affiliation":[{"name":"Orthopaedics, All India Institute of Medical Sciences Kalyani, Kalyani, West Bengal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bismaya","family":"Sahoo","sequence":"additional","affiliation":[{"name":"Orthopaedics, All India Institute of Medical Sciences Kalyani, Kalyani, West Bengal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0738-2809","authenticated-orcid":false,"given":"Saurabh","family":"Raj","sequence":"additional","affiliation":[{"name":"General Surgery, All India Institute of Medical Sciences Kalyani, Kalyani, West Bengal, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,7,21]]},"reference":[{"key":"2025082709403291000_18.7.e263362.1","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(14)70063-8"},{"key":"2025082709403291000_18.7.e263362.2","doi-asserted-by":"crossref","first-page":"939","DOI":"10.1016\/B978-0-444-52902-2.00053-9","article-title":"Neurofibromatosis type 1 (NF1): diagnosis and management","volume":"115","author":"Ferner","year":"2012","journal-title":"Handb Clin Neurol"},{"key":"2025082709403291000_18.7.e263362.3","doi-asserted-by":"publisher","DOI":"10.1177\/088307380201700802"},{"key":"2025082709403291000_18.7.e263362.4","doi-asserted-by":"crossref","unstructured":"Upadhyaya M , Cooper DN .
