What Is a Pulmonary Embolism?
A pulmonary embolism is a type of blood clot that affects a blood vessel, typically in the leg. This clot may move to a lung artery and unexpectedly restrict blood flow in the body. In most cases, the symptoms can be life-threatening as the blood flows to major organs are affected. Nevertheless, quick treatments can help lower the risk of casualty. People can also take preventive measures to avoid blood clots in their legs.
