Sleep Apnea Following Percutaneous Cervical Cordotomy

Abstract

ABSTRACT:Sleep apnea (Ondine's Curse) is an uncommon but potentially fatal complication of percutaneous cervical cordotomy. The authors have had the opportunity to review the case histories of 6 patients who have died of sleep apnea following this procedure. In a series of 112 patients, 144 cervical percutaneous cordotomies were performed from 1977 to 1985 — 80 unilateral cordotomies and 32 staged bilateral cordotomies. Six (5%) patients died as the result of sleep apnea. Five patients (16%) died following bilateral cordotomy and one (1%) patient with pulmonary disease died following unilateral cordotomy. The clinical data of these 6 patients are presented and unique spinal cord pathology is described in this report. The pathophysiology of the sleep apnea syndrome is also discussed.
