Causes of Pulmonary Embolization
Blood clots, or thrombi, can occur in the body due to a number of factors. The thrombi that cause pulmonary embolism are most commonly caused by deep vein thrombosis. This condition allows blood clots into the deep veins in the body. Blood clots are the main cause of pulmonary embolism. They usually travel from the leg or pelvis veins to the lungs. Virchow’s triad is a term used by medical professionals to describe three factors that can cause pulmonary embolism. These include sedentary living, hyper-coagulability and trauma to veins. There are many reasons why blood clots can form in the deep veins. These include:
Physical trauma or injury
Blood clots can form when blood vessels are damaged by injuries like bone fractures and muscle tears. The blood clots travel from the injury site to other parts of the body, including the lungs. After reaching into the lungs, these blood clots not only block the blood flow but also decrease the space for gas exchange at the alveolar sacs thus causing mismatch in ventilation/perfusion ratio. A lower leg injury can damage a blood vessel or blood vessel wall. This can lead to the formation of blood-clots within the deeper veins. These blood clots start to move towards the lungs, causing pulmonary embolism.
