Upper-airway obstruction after multilevel cervical corpectomy for myelopathy
SE Emery, MD Smith and HH Bohlman
Department of Orthopaedics, University Hospitals, Cleveland, Ohio.
We reviewed the cases of seven patients who had had obstruction of the
upper airway immediately after an anterior procedure on the cervical spine
and had required reintubation. All patients had had moderate or severe
myelopathy preoperatively (average, 3.6 on the Nurick scale), and all had
had a multilevel anterior cervical corpectomy for decompression followed by
arthrodesis. The early compromise of the upper airway was believed to be
due to edema rather than to the formation of a hematoma. Five patients had
no sequelae, but two died of complications related to the obstruction. Risk
factors common to these patients included moderate or severe myelopathy and
multilevel corpectomy. Six patients had a history of heavy smoking and one,
of asthma. We believe that extra caution should be used in the
postoperative management of the airways when multilevel corpectomy is
performed in patients who have these pre-existing conditions.
