Research into Morphofunctional Characteristics of Erythrocytes in COVID-19 Patients.

In this paper, the erythrocytes of healthy donors and people with a confirmed diagnosis of COVID-19 were tested by Raman spectroscopy and laser interference microscopy. We argue that erythrocytes (red blood cells) in COVID-19 patients have an irregular shape, and their morphometric characteristics are impaired in comparison to healthy red blood cells. Raman spectroscopy also allows us to detect a decreased oxygen transport function of these erythrocytes.

[Results of endovascular treatment of acute tandem occlusion of internal carotid and middle cerebral arteries].

Objective: To evaluate the results of endovascular treatment of patients with ischemic stroke caused by acute tandem occlusion of the internal carotid and middle cerebral arteries (ICA and MCA).

Material And Methods: Endovascular intervention was performed in 8 patients with tandem occlusion of ICA and MCA. The neurological deficit on admission was 17.

[Endovascular interventions in treatment of patients with acute impairment of mesenteric blood circulation].

The authors share herein their experience of treating a total of eight patients with acute impairment of mesenteric blood circulation, describing both technical and instrumental peculiarities of interventions on the superior mesenteric artery. Technical success defined as restoration of the main blood flow through the superior mesenteric artery was achieved in seven (87.5%) patients.
