RESUMEN
BACKGROUND: Surgical resection of vertebral hemangiomas in the setting of cord compression can be technically difficult and has the potential for life-threatening hemorrhage. The authors report a case of intraoperative direct intralesional n-butyl-cyanoacrylate embolization for intractable vertebral hemangioma bleeding. OBSERVATIONS: A 53-year-old woman presented for repeat surgery of a residual vertebral hemangioma after a previous debulking, laminectomy, and fixation that were without problems with bleeding. The second surgery was complicated by intractable hemorrhage. Bleeding was controlled with direct intralesional n-butyl-cyanoacrylate embolization after fluoroscopy without accompanying endovascular embolization. LESSONS: Aggressive vertebral hemangiomas should ideally be managed in centers where transarterial embolization is available. If such centers are not available or there is still intractable intraoperative bleeding despite preoperative embolization, direct intralesional embolization may be considered as a potential salvage technique.
RESUMEN
Post-operative dysphagia is the most common complication following anterior cervical discectomy and fusion (ACDF), with reports varying from 1% to 79%. We report a case of a 63-year-old female patient complaining of dysphagia presenting 9 years post surgery. The cause of dysphagia is often multifactorial with the true aetiology poorly understood. One potentially life-threatening cause of post-operative dysphagia is hardware migration associated with pharyngoesophageal perforation. This patient presents a unique case of a conservatively managed hardware migration with delayed onset dysphagia after 8 years of minimal symptoms. On further investigation, barium swallow identified a freely mobile screw in the oesophageal submucosa, rotating on swallowing. Retrieval of the screw was achieved transcervically with no visible perforation and resolution of dysphagia occurred 1 week post-operatively. Understanding the aetiology with early diagnosis and appropriate management of delayed hardware migration are paramount in reducing patient morbidity and potential life-threatening otolaryngologic complications.
