[Surgical complications in patients with COVID-19]

To analyze in-hospital perioperative complications in COVID-19 patients.

We analyzed medical records of 1.250 patients with COVID-19 for the period from April 2020 to December 2021. Mean age of patients was 62.8±2.1 years, length of hospital-stay - 44.3±3.7 days. All patients received therapy in accordance with the national guidelines on prevention, diagnosis and treatment of new coronavirus infection (COVID-19)» (versions 1-12). Visualization of hematomas, arterial and venous thrombosis was performed using ultrasound, CT and CT angiography.

Mortality rate was 1.5%. Surgical complications included various hematomas, arterial and venous thrombosis of great vessels. Hematomas were detected in 15 (1.2%) patients, 2 of them died. There were hematomas of extremities in 5 cases, retroperitoneal space - 4, soft tissues of the body - 4, internal organs (spleen) -2 patients. The volume of hematoma was up to 100 ml in 6 patients, 100-500 ml in 5 patients, 500-1000 ml in 3 patietns, more than 1000 ml in 1 patient. Hematomas occurred in 23.1±1.1 days after laboratory verification of COVID-19. Four (26.7%) patients underwent emergency surgery. Conservative therapy was followed by lysis of hematoma after 25.1±2.7 days. Venous thrombosis without signs of flotation occurred in 20 (1.6%) patients, arterial thrombosis - in 3 (0.24%) patients (2 ones required surgery).

Management of COVID-19 patients with various hematomas should be as conservative as possible. Arterial thrombosis and extensive spleen hematomas requiring surgical treatment are features of COVID-19.
