Embolism is a dangerous and hard on the body condition. Characterized by transferring foreign to blood composition elements leading to blockage of the blood vessel. Transmitted matter bears the name “embolus”. The latter can be of endogenous origin – thrombi, oil drops and tumor cells, and of exogenous origin – bacteria, parasites.
Thromboembolism is the most common embolism. It is a critical condition which is observed at the branches of the pulmonary artery. In a large percentage of cases leads to death. If there is venous stasis in the lung develops necrosis in the parenchyma perfused by this court. This necrosis is referred to as hemorrhagic infarction.
Fat embolism is the second most common after thromboembolic events. Proceeds with carrying fat droplets in the blood stream. Cause of fat embolism is crushing subcutaneous adipose tissue in trauma or fractures of long tubular bones containing fatty marrow. Fat droplets spread veins, reaching the lung, where clog the pulmonary capillaries. As a result, occurs acute respiratory failure which is fatal.
Amniotic embolism may occur as a complication after birth. It represents a huge risk to the mother. However, its frequency is low – once in 50,000 births, but 86% of the cases fatal. Due to the rupture of the placental membrane rupture of the veins of the uterus, in which amniotic fluid enters the blood stream of the mother. As a result, acute respiratory failure occurs due to clogging of the capillaries of the lung.
Air and gas embolism. Characterized entry of air bubbles or gas into the bloodstream. This leads to obstruction of the vessels, which occurs in tissue damage. Example of gas embolism is aeroembolism.
