Pulmonary embolisms usually start out as a DVT or deep vein thrombosis or a blood clot in one of the major veins. These can form for a number of reasons. If someone has blood that is more prone to clotting than others or if they don't move for an extended period of time which would allow the blood to pool in the vein. When the clot has formed it will stay in the limb that it had started in for a period of time, mine was stayed in my leg a week before moving. When it moves it follows the blood flow to the lung, then it gets stuck there again causing the pulmonary embolism or lung blood clot. The sequential order of a blood clot in the leg or DVT is pieces of thrombus break off and travels up the vein to the inferior vena caba to the right atrium, through the biscupid valve to the right ventrical, then through the pulmonic valve into the pulmonary artery into the lung. Until it gets to a portion of artery that is so small the clot can't pass any further. At that point the clot forms an obstruction.
What else can I help you with?
What is a saddle pulmonary embolism?
A saddle pulmonary embolism is an occlusion of the left and right portion of the pulmonary artery
What is a pulmonary embolism?
A pulmonary embolism is a blood clot in the lung. Clots that form elsewhere in the body can become lodged in the blood vessels leading from the right ventricle to the lungs.
What is dose of heparin for pulmonary embolism?
Only your doctor can tell for sure what is right for you!
Is Pulmonary Embolism the same as Pulmonary Hypertension?
A pulmonary embolism is also characterized as central or peripheral, depending on the location or the arterial branch involved. Central vascular zones include the main pulmonary artery, the left and right main pulmonary arteries, the anterior trunk, the right and left interlobar arteries, the left upper lobe trunk, the right middle lobe artery, and the right and left lower lobe arteries.
What is the pathway that an embolism from the great saphenous vein of the leg would take before lodging in the pulmonary artery?
An embolism from the great saphenous vein in the leg would first travel through the venous system into the femoral vein, then into the external iliac vein. From there, it would enter the common iliac vein and subsequently the inferior vena cava. Finally, the embolism would flow into the right atrium, pass into the right ventricle, and then be pumped into the pulmonary artery, where it may lodge and cause a pulmonary embolism.
Can a pulmonary embolism cause heart block?
Yes, a pulmonary embolism can potentially cause heart block, particularly if it leads to significant strain on the right side of the heart or results in acute right heart failure. This strain can disrupt normal electrical conduction pathways, potentially leading to various types of heart block. Additionally, severe hypoxia or changes in hemodynamics due to the embolism may also contribute to arrhythmias or conduction abnormalities. However, heart block is not a common direct consequence of pulmonary embolism.
Vena cava compression are obstructions which cause what type of shock syndrome?

What is the difference between cor pulmonale and pulmonary embolism?
A pulmonary embolism is a tissue fragment (part of a blood clot, fat, amniotic fluid, part of a tumour or bullet fragment) that became loose in the blood stream and was carried by the blood stream to a different location. A pulmonary embolism is, in most cases, a thromboembolism (part of a blood clot), which is carried from the deep veins of the legs or the pevis. It travels up the blood stream, through the inferior vena cava, into the heart, and subsequently into the pulmonary artery. In the pulmonary artery, it arrests, forming a potentially life threating occlusion. Cor pulmonale is hypertrophy of the right ventricle due to chronic pulmonary hypertension. The pulmonay hypertension means that the right ventricle has to pump blood with greater force, causing its muscle to hypertrophy (enlarge in size). Therefore, to summarize, a pulmonary embolism is an obstruction of pulmonary blood flow while cor pulmonale is the morphological change of the right ventricle due to pulmonary hypertension.
What keeps blood from passing into the right atrium?
Well, its supposed to get into the right atrium as part of the Pulmonary and Systemic circuits, but it could be prevented by a hole somewhere or some sort of embolism
Jugular vein distention is associated with?
right-sided heart failure, when the right ventricle is hypertrophied or dilated which is secondary to pulmonary hypertension (usu. d/t pulmonary embolism in acute cor pulmonale, but d/t COPD in chronic cor pulmonale)
What might a person feel like if there was a blood clot blocking the left and right pulmonary arteries?
Pulmonary embolism is a very non specific problem. Many people may have varrying levels of chest pain and most commonly seen is a non productive cough that won't go away.
Does pulmonary embolism lead to pulmonary edema?
Congestive heart failure can cause pulmonary edema but I am not sure about an embolism.Congestive heart failure (CHF) depending on the severity of the condition can cause pulmonary edema. As the disease progresses, if the patient has left sided CHF, the blood does not flow properly and will get backed-up into the lungs thereby causing pulmonary edema. For those with right-sided heart failure, you will get back-up into the peripheral vascular system and will have edema of the extremities (hands and feet). As for the embolism, again, as the CHF worsens, the work of the heart is increasing and the heart is not effectively pumping the blood. As the heart begins to pump less and less blood with each contraction, you can get stagnation of the blood in the chambers of the heart. Blood clots (ie embolism) can occur. This is also true for individuals who have atrial fibrillation because the blood is not effectively pumped out of the heart.
