Thyroidectomy Complicated by Severe Septic Shock Due to Streptococcus pyogenes: A Case Study

<b>Background</b>: In recent years, the incidence of thyroid cancer has been increasing due to environmental, biological, and genetic factors. One of the treatment methods for thyroid cancer is strumectomy, a procedure associated with a high risk of postoperative complications. <b>Methods</b>: The following case presents septic shock with sudden cardiac arrest and cardiopulmonary resuscitation, caused by <i>Streptococcus pyogenes</i>, in a 45-year-old woman who underwent surgery for papillary carcinoma. <b>Results</b>: The patient required long-term interdisciplinary treatment in the Clinical Department of Anesthesiology and Intensive Care. <b>Conclusions</b>: Necrotizing mediastinitis after thyroidectomy caused by <i>Streptococcus pyogenes</i> is a rare and dangerous complication. The analysis of the case proves how important the preoperative assessment of the patient's health (especially taking a detailed history) and the patients' awareness of possible risk factors are. An equally important aspect is the awareness of the therapeutic team regarding the transmission of infections, their dynamics, and the consequences of the procedures undertaken.
