Coexistence of Obstructive Sleep Apnea and Superior Vena Cava Syndromes Due to Substernal Goitre in a Patient With Respiratory Failure: A Case Report.

BACKGROUND

Substernal goiter may rarely cause superior vena cava syndrome (SVCS) owing to venous compression, and cause acute respiratory failure due to tracheal compression. Obstructive sleep apnea syndrome (OSAS) may rarely occur when there is a narrowing of upper airway by edema and vascular congestion resulting from SVCS.

METHODS

We presented the clinical course and treatment of acute respiratory failure (ARF) developed in a patient with SVCS and OSAS due to substernal goiter. After treatment of ARF with invasive mechanical ventilation, weaning and total thyroidectomy were successfully performed through collar incision and median sternotomy without complications.

CONCLUSIONS

Our case showed that if the respiratory failure occurred due to substernal goiter and SVCS, we would need to investigate the coexistence of OSAS and SVCS.
