​Clots and air blocks: Has Pulmonary Embolism increased after COVID?

​What is Pulmonary Embolism?

A pulmonary embolism is a blob of blood clot/ fat/ air that blocks and stops blood flow to an artery in the lungs. Most clots start in the deep veins of the legs and travel to the lungs. Rarely, blood clots form in veins in other parts of the body. When blood clots form in one or more deep veins in the body, it is called deep vein thrombosis (DVT).
2/6

​How risky is this health condition?

Pulmonary embolism can be life-threatening because one or more blood clots block blood flow to the lungs and cause lack of oxygen. This makes it difficult for the lungs to deliver oxygen to the rest of the body. However, prompt treatment greatly reduces the risk of death.

3/6

​Causes of Pulmonary Embolism:

Bedridden patients who have had major surgeries and are unable to mobilize well for more than 3 weeks, those with cancers, those with clotting disorders, those who are on oral contraceptives, or women who have a history of multiple miscarriages are prone to this condition. The root cause needs to be evaluated and can be eventually fully treated and cured.

4/6

​Here’s what the expert says:

Dr. Sivaresmi Unnithan, Pulmonology, Fortis, Anandapur, says, “The long-term health effects of COVID-19 are still largely unknown. This review highlights the importance of recognizing the potential increased incidence of venous thromboembolism in post-COVID-19 patients, even in those with mild or asymptomatic disease. I am emphasizing that further research is needed to establish appropriate clinical treatment guidelines to prevent thromboembolic complications in the post-COVID-19 period.”

5/6

Health risks involved with post COVID clotting:

Blood clots can result in issues that range in severity from minor to fatal. If a blood clot restricts blood flow in an artery or vein, the tissue normally supplied by that blood channel may become oxygen-deprived, which may cause the cells in that area to perish.

A stroke can be brought on by blood clots in the arteries that supply the brain. Some COVID-19 patients who were previously young and healthy also experienced strokes, which may have been brought on by irregular blood coagulation.

Kidney failure may result from blood clots blocking the kidney's blood arteries.

6/6

After COVID effect

Although COVID-19 has been viewed primarily as a respiratory disease, rapidly accumulating data suggested that COVID-19 is associated with a high incidence of venous thromboembolic complications.

“In COVID-19, a prothrombotic condition develops that may be brought on by heightened coagulation, diminished fibrinolysis, and immunological reactions. In COVID-19, endothelial inflammation, disruption of intercellular connections, and the production of microthrombi are all distinct microvascular abnormalities,” says Dr. Unnithan.
