Arteries are blood vessels that carry oxygen-rich blood away from the heart to the body, while veins carry blood low in oxygen from the body back to the heart. Covid produces blood clots. “Studies have shown that around 20 to 30 per cent of hospitalised COVID-19 patients have developed this complication," he told PTI. Some of these clots occupy big blood vessels and become macroscopic blood clots. “The virus invades these blood vessels and starts affecting the inner lining of these blood vessels which produces a dysfunction within the blood vessels which produces these clots," the surgeon said.
