Covid-19’s latest deadly surprise: Mysterious blood clots


The right leg of the player, Nick Cordero, who stayed in the intensive care unit for about three weeks and received Covid-19 treatment, was cut.

Their doctor said that Cordero, 41, whose blood flow was blocked due to clotting, decided to cut his foot.

Thrombotic events occur very often in intensive care patients for a variety of reasons.

However, in Covid-19 patients, this rate is stated to be at a high level far beyond the estimates.

“I have patients in their 40s who have a clot in their intensive care unit, and I think they will lose their fingers in the intensive care unit, and they will only lose their fingers for the virus, not for any other reason.” says.

One of the patients suffers from a lack of blood circulation in both hands and feet. His doctor thinks that amputation may be necessary. Or its veins can be damaged enough that the tips of the hands and feet can fall off on their own.

Blood clots are dangerous not only for the limbs, but also for the lung, heart or brain.

Because clot can cause deadly pulmonary embolism (sudden occlusion of the lung artery), heart attack and strokes in these areas.

A recent study published in the Journal of Thrombosis Studies from the Netherlands revealed that 31 percent of 184 patients in this country experience thrombotic complications.

Researchers state that this figure is quite high. As a result, although the rate of amputation (cutting any organ) is not high.

Thrombotic episodes or thrombosis is caused by blood clotting inside the vein causing blockages in the heart, lungs and veins.

Why is this happening?

Doctor Behnood Bikdeli from New York Presbyterian Hospital established an international expert consortium to study the issue.

The team’s findings were published in the American Journal of Cardiology.

Accordingly, experts determined that the risks to Covid-19 patients are enormous.

“Covid-19 patients may need to take preventive, prophylactic blood thinners even before testing,” said Doctor Bikdeli. used expressions.

What exactly does it cause?

Although the reasons are not fully understood, Bikdeli’s team’s research offers several possible possibilities.

People with Covid-19 disease often have other underlying causes, such as heart or lung disease, which themselves are already associated with higher clotting rates.

The second reason is to stay in intensive care. When the person is immobile for too long, the clot is likely developing in the body.

Another is that Covid-19 disease is associated with an abnormal immune reaction called “cytokine storm”. Some research even reveals that this is linked to higher clotting rates.

It is also stated that the virus may be something that directly causes clotting, and its peers in other viral diseases are exemplified.

On the other hand, in an article published in Lancet magazine last week, it was shared that the virus could infect the inner cell layer of organs and blood vessels called endothelium.

Theoretically, this also means intervention in the coagulation process.

Micro clots

According to Brosnahan, thinners like Heparin are effective in some patients, but not in all patients because clots are sometimes very small.

“There are too many microclots.” “We’re not sure exactly where they are,” Brosnahan said. she adds.

However, the arrival of a new mystery can contribute to resolving an older enigma.

“The lungs filled with micro-clots help explain why ventilators don’t work well in patients with oxygen deficiency,” says Cecilia Mirant-Borde, an intensive care doctor at a military hospital in Manhattan.

In the first period of the epidemic, doctors treated patients with the method developed for acute respiratory distress, also known as “wet lung syndrome”.

In some cases, however, this was due to the fact that the lungs are not filled with water, but rather because microcoagulation inhibits blood circulation and the blood leaves less oxygen than it should be in the lungs.

“Viruses tend to act mysteriously”

More than 5 months have passed since the virus appeared in Wuhan, China, and researchers learn more about the effects of Covid-19 every day during this time.

“We shouldn’t be surprised if we react with surprise because viruses tend to behave mysteriously.” “Even though the dizzying complications of the virus seem daunting, it is possible that there will be one or more unifying mechanisms that explain how the damage occurred. Eventually, a solution will be found.” Brosnahan said. says.

Experts state that Covid-19 increases blood clotting, causing complications from many cardiovascular systems such as heart attack, cardiac muscle inflammation, rhythm disturbances, clotting and embolism.

While the body’s defense mechanism, which acts against Covid-19, fights the virus, it can also damage one’s own organs.

For example, people with coronary vascular disease can disrupt the structure of vascular plaques, increase the risk of heart attack, and damage the heart’s functioning by holding the heart muscle.

In addition, it increases blood clotting, impairs blood flow, may cause elevated blood pressure, and prepares the ground for coagulation in the vessels.
