“What Covid clots look like. Covid produces blood clots. The incidence of heart attack, stroke, or limb loss due to an arterial clot in Covid varies from 2 percent – 5 percent. We pried these out of the lower limb arteries of a Covid patient. We were able to save the limb”.
Mr Satwik explained his tweet, which drew a lot of attention and questions, saying the COVID-19 patient had an acute circulatory cutoff due to the clots, and the limb was in danger. The surgeon explained, “So we had to physically do a surgical procedure and extract these clots, otherwise there would have been gangrene, and he would have ended up with an amputation. We were successfully able to take the clots out and save the limb”.
According to the authors of a Lancet paper published in November last year, studies indicate a connection between COVID-19 and the risk of thromboembolism (TE), which is the obstruction of a blood vessel by a blood clot. The authors of the study concluded that COVID-19 TE concentrations are high and linked to an increased risk of death. Mr Satwik said, “We have been understanding the pathophysiology of COVID-19 for over a year now. When it first hit China and the global west, it was thought that it was typical viral pneumonia. Severe cases of acute COVID-19 were being labelled as similar to the acute respiratory distress syndrome (ARDS), which leads to respiratory failure”.
A series of autopsies on COVID-19 patients and their lungs, on the other hand, showed that the doctors were not seeing traditional ARDS. Mr Satwik added, “…in addition to that, they were finding clots in the microcirculation of the lungs. So it was then kind of understood that COVID is as much a disease of blood vessels as much it’s a disease of the lungs”.
According to Mr Kumar, When blood vessels in a COVID-19 patient are injured, they release a protein that attracts platelets and other clotting factors, which then combine to form a clot. He said, “Studies have shown that around 20 to 30 percent of hospitalised COVID-19 patients have developed this complication”.
According to Mr Satwik, since blood vessels can be found all over the body, clots can form anywhere. Some of these clots become macroscopic blood clots as they occupy large blood vessels. He said, “But otherwise we are seeing diffused microscopic clots in microcirculation in various organs”.
According to a study published in April by the University of Oxford, the chance of rare blood clotting after COVID-19 is…
