Background:
Injury to thoracic duct is a rare potential complication of time-honored conventional thyroidectomy. Nevertheless, it can be a cause of significant morbidity, and sometimes life-threatening.
Patient findings:
A 78-year-old female patient with a previous surgical history of thyroid lobectomy for nodular disease presented with primary hyperparathyroidism, and a nodule in the remaining thyroid lobe. The patient underwent completion thyroidectomy and parathyroidectomy. Less than 24h post operatively, the patient developed progressive shortness of breath and neck swelling requiring immediate intubation and re-exploration. A large amount of chyle was drained and an injured thoracic duct was identified and ligated.
Summary:
In experienced hands thyroid surgery is safe. Nevertheless, factors such as the type of pathology and its extent, the level of surgery, and re-operative surgery increase the risk of postoperative complications. Immediate surgical exploration is necessary when patients present with neck swelling and respiratory distress. In our case, a high output chyle leak in a confined space was life threatening.
Conclusion:
Timely re-exploration following thyroid surgery and thorough knowledge of the anatomy of neck structures is crucial in sparing patients potential morbidity and/or mortality.
