According to scientific studies that analyzed comorbidities in patients who died from COVID-19 the most common pathology is arterial hypertension (AH). During hospitalization patients with hypertension in most cases feel worse than patients with other pa-thologies and, therefore the COVID-19 pandemic is a special problem for them. Objective. Morphological description of organs in COVID-19 patient with hypertension and aortic aneurysm. Material and methods. The analysis of medical documentation (outpatient medical records, medical history), clinical and morphological analysis using histological and immunohistochemical studies. Results. Patient B., 61 years old, was hospitalized with a diagnosis of Coronavirus infection. Out-of-hospital bilateral pneumonia, severe. A history of hypertension. Despite the treatment there was no positive dynamics in the patient’s condition and death was de-clared. In sectional examination the signs characteristic of aortic dissecting aneurysm were determined. On the sections between the visceral and parietal plates of the pericardium at the bases of the ventricles there were hemorrhages with dissection within the bases of the ventricles and with the transition to the atria. Detachment of the aortic intima began from the orifice to the distal aortic arch. An immunohistochemical study of elastin showed pronounced fragmentation of elastic fibers. The lungs showed signs of edema and diapedetic hemorrhages with moderate lymphocytic infiltration with disatelectasis in some places. Conclusion. The main cause of the patient’s death was a dissecting aortic aneurysm according to Stanford — type A, according to DeBakey — type II. The associated viral pneumonia aggravated the course of the disease and affected the death.
