Pulmonary embolism (PE) is that the patient's blood to form clots (often in the deep veins of the lower limbs), which entered the bloodstream into the pulmonary artery. This leads to partial or complete blockage of blood vessels that carry blood from the heart to the lungs.
Normally, the blood is coming from the right heart to the lungs where it absorbs oxygen and gives carbon dioxide. The vessel on which the blood goes to the lungs is called pulmonary artery. Sated with oxygen and carbon dioxide by giving the blood system in the pulmonary veins returned to the systemic heart. Thence through the aorta, and from there into smaller arteries, blood, oxygen-rich, goes to the tissues and organs. Next, the system of veins, which are collected in two major veins - the upper and lower hollow - it goes back to the right of the heart. Then the circle again repeated.
In the case of a patient such diseases as deep vein thrombosis of lower extremities are at risk of separation of clot formation or part. Detached thrombus with blood comes through veins to the right around the heart. From there, he falls into the pulmonary artery. Depending on the size and number of blood clots, the manifestations of thromboembolic pulmonary artery branches can vary. No less typical place of blood clots are the veins of the prostate.
