ABSTRACT
The Chiari malformation type I (CM-I) has been associated with sleep-disordered breathing, especially central sleep apnea syndrome. We report the case of a 44-year-old female with CM-I who was referred to our sleep laboratory for suspected sleep apnea. The patient had undergone decompressive surgery 3 years prior. An arterial blood gas analysis showed hypercapnia. Polysomnography showed a respiratory disturbance index of 108 events/h, and all were central apnea events. Treatment with adaptive servo-ventilation was initiated, and central apnea was resolved. This report demonstrates the efficacy of servo-ventilation in the treatment of central sleep apnea syndrome associated with alveolar hypoventilation in a CM-I patient with a history of decompressive surgery.
RESUMO
A malformação de Chiari tipo I (MC-I) tem sido associada a distúrbios respiratórios do sono, sobretudo à síndrome de apneia central do sono. Apresentamos o caso de uma paciente do sexo feminino de 44 anos de idade com MC-I que foi encaminhada à nossa unidade de sono por suspeita de apneia do sono. A paciente havia sido submetida a cirurgia descompressiva 3 anos antes. A gasometria arterial mostrou hipercapnia. A polissonografia revelou um índice de distúrbio respiratório de 108 eventos/h, sendo todos os eventos apneias centrais. Foi iniciado tratamento com servoventilação adaptativa e houve resolução da apneia central. Este relato demonstra a eficácia da servoventilação no tratamento da síndrome de apneia central do sono associada à hipoventilação alveolar em uma paciente com MC-I previamente submetida a cirurgia descompressiva.
