Abstract

BACKGROUND: High risk of thrombotic complications is typical for patients with COVID-19-associated pneumonia, including in the postoperative period. Multispiral computed tomography (MSCT) with intravenous bolus contrast in assessing the condition of the pulmonary arteries improves visualization of the vascular bed, allowing to clearly determine the presence of thrombi, the degree of stenosis, occlusion. This method is non-invasive and highly informative, which allows to quickly and accurately diagnose such life-threatening conditions as pulmonary embolism (PE), as well as to exclude or confirm other vascular pathologies. MSCT with intravenous bolus contrast is a modern, fast and accurate diagnostic method that allows to timely identify and evaluate pathological changes in the pulmonary arteries, which is critical for choosing the optimal treatment tactics and improving the patient's prognosis.

AIM: To evaluate the method of multislice computed tomography with intravenous bolus contrast in the diagnosis of pulmonary embolism in patients with COVID-19-associated pneumonia; to study the relationship between the incidence of PE and the degree and stage of pneumonia caused by SARS-CoV-2.

MATERIALS AND METHODS: The retrospective research was conducted included 184 patients with COVID-19-associated pneumonia and suspected pulmonary embolism (PE) according to laboratory tests. Patients underwent contrast-enhanced multispiral computed tomography (MSCT-AG) to assess the state of the branches of the pulmonary arteries and lung parenchymal changes.

RESULTS: According to the study, every 5th patient was diagnosed with PE with a predominantly mild degree of perfusion deficiency and a minimal volume of pneumonia-damaged lung parenchyma.

CONCLUSIONS: The study demonstrated the high information content of the MSCT-AG method in diagnosing pulmonary embolism in patients.
