The patients who died of COVID had a lot of water in their lungs and a lot of clots in the small blood vessels, says medical examiner Cristian Stan. He dispelled the myth that “one does not die from COVID”, but from other diseases that patients had and explained how organs give way due to infection.
“The deceased patients, who were autopsied after infection with the SARS CoV2 virus, also had a bacterial superinfection. This infection drastically lowers the immune capacity of the lungs and then any bacteria are grafted into the lungs and bronchopneumonic foci appear. But from the point of view of the evolution of viral pneumonias, that is the rule “, said the doctor.
The deceased COVID patients had “very hydrophilic pulmonary edema, a lot of water in the lungs, there was pulmonary thrombosis in almost all stages of the disease – small blood vessels with clots. The effect of these clots, especially in the early stages of the disease, is that they practically stop the arrival of blood and lung tissue dependent on that clot. Thus, on the one hand, local inflammation is accentuated and, on the other hand, oxygenation of the blood decreases ”, he added.
There are some particular cases in the COVID-19 disease, the so-called “silent hypoxia” or “happy hypoxia”, in which the patient has a decrease in oxygen in the blood, but is not short of breath, which should occur when concentrating of oxygen. There are various theories. One of them says that if the carbon dioxide in the blood does not increase, practically the brain centers do not react ”, explained the forensic doctor.
“The idea is that the COVID-19 disease, from what I have seen and read, differs from other viral pandemics by several characteristics. One of them is that it does not have a linear evolution, it has an evolution either with a sudden drop in health , or in two stages, or an apparently positive evolution but with coagulation phenomena that cause some effects of infarction – myocardial, cerebral, renal obstructions or other types of vascular obstructions that deteriorate health suddenly and unexpectedly. That is why it is somehow way a very misleading disease.In my opinion, this is the most important feature.
There is also liver damage, but it is not as common. There is brain damage, there are cases of encephalitis, encephalopathies that have been reported in international journals, there are neurological disorders – loss of smell, loss of taste, loss of balance or other types of neurological disorders, even psychiatric, that can be explained by brain invasion by viruses or there may be explanations for this obstruction of the small cerebral vessels by these thrombi that appear in the early stages of the disease ”, said Cristian Stan.
Dr. Adrian Marinescu explained, in turn, that these microthromboses reach everywhere.
“It is obvious at this point that changes in coagulation occur regardless of shape, especially if they are medium and severe. We can affect practically any organ,” he said.
Cristian Stan also explained that “he dies of COVID”, since there were voices that assured that the deaths of infected patients were not caused by the virus, but by the diseases they already had.
“The infection is what causes the patient to reach the collapsed state of immunity and, of course, all subsequent septic phenomena or multi-organ failure or systemic inflammatory syndrome are caused by this viral infection.” It is true that the vast majority can die from organ failure, which is mixed, septic and inflammatory, but it is the viral disease that creates the premises for these complications. It’s scientifically obvious, “he said.
