Patient's question:
Recently, I don't know why I've been feeling discomfort in my heart. Although I take medication to control it, the effect is not obvious. When I went to the hospital for a check-up, they also prescribed medication. Could you please tell me what the main source of thrombi in acute pulmonary embolism is?Doctor's answer:
Hello, for patients who experience recurrent acute pulmonary embolism, the source of the embolus is primarily the venous system. The most common site is the lower extremity veins. Some people are inactive, or have lower extremity trauma, which are all risk factors for lower extremity venous thrombosis. If deep vein thrombosis recurs in the lower extremity, it is very easy to cause the thrombus to detach. Once it enters the right heart, it will lead to the recurrence of pulmonary embolism.
