The severe course of the new coronavirus infection (COVID-19) is associated with multiple life-threatening complications that lead to delayed initiation of active rehabilitation and unfavorable long-term treatment outcomes. Tracheoesophageal fistula is one of these complications. The specific feature of this event in COVID-19 is delayed tissue regeneration which requires a non-standard approach to management of such patients.The article presents a clinical case of a pregnant patient after a complicated severe course of COVID-19 with the development of tracheoesophageal fistula, sepsis, and weakness syndrome acquired in ICU. The combination of complications of the disease led to a prolonged (about five months) period of rehabilitation.Modern standard components of intensive therapy of such patients including regular monitoring of endotracheal/tracheostomy tube cuff pressure, dynamic assessment of nutritional status and its correction, rational antimicrobial therapy, screening of psychiatric disorders and early rehabilitation, will minimize the number of both early and delayed complications of COVID-19.
