Pulmonary embolism or deep vein thrombosis is a serious medical condition. Blood clot formation is its primary cause. When this clot enters the bloodstream, there's a high risk for it to reach the lungs. Consequently, the clot hinders the lung arteries and curtails the oxygen and blood flow. Usually, it develops inside the deeper veins in the legs. When detected, the pulmonary embolism treatment must be immediate as it may prove to be fatal without immediate care.
