Pathophysiology may involve complete stasis of venous and arterial blood flow in the lower extremity because venous return is occluded or massive edema cuts off arterial blood flow. Front Bioeng Biotechnol. Following is a list of causes or underlying conditions (see also Misdiagnosis of underlying causes of Thromboembolism) that could possibly cause Thromboembolism includes: . In most cases, pulmonary embolism is caused by blood clots that travel to the lungs from the legs or, rarely, other parts of the body (deep vein thrombosis).
