    Abstract:
    BACKGROUND Chronic graft-versus-host disease (GVHD) is a major complication of hematopoietic stem cell transplantations. Due to fibrotic changes, patients with GVHD are at risk for difficult airway management. We encountered a case of chronic GVHD that went into a "cannot intubate, cannot ventilate" (CICV) condition after induction of general anesthesia and was managed using cricothyrotomy. CASE REPORT A 45-year-old man with uncontrolled chronic GVHD developed pneumothorax of the right lung. Thoracoscopic dissection of the adhesions, closure of the pneumostomy, and drainage under general anesthesia were planned. In the preoperative airway assessment, we concluded that using a video laryngoscope or endotracheal fiber would be sufficient to intubate the patient after sedation and that airway management after the loss of consciousness would not be difficult. Therefore, general anesthesia was induced by rapid induction; however, the patient developed difficult mask ventilation. Intubation was attempted via a video laryngoscope or bronchofiber but failed. Ventilating using a supraglottic instrument was difficult. The patient was evaluated to have a CICV condition. Thereafter, because of a rapid decrease in oxygen saturation (SpO2) and bradycardia, a cricothyrotomy was performed. Subsequently, ventilation became adequate, SpO2 increased immediately and drastically, and respiration and circulatory dynamics recovered. CONCLUSIONS We believe that anesthesiologists should practice, prepare, and simulate airway emergencies that can be experienced during surgery. In this case, we recognized that skin sclerosis in the neck and chest could lead to CICV. It may be suitable for airway management of scleroderma-like patients to select conscious intubation with a bronchoscope as a first choice.
