Contusion involves hemorrhage in the alveoli (tiny air-filled sacs responsible for absorbing oxygen), but a hematoma is a discrete clot of blood not interspersed with lung tissue. [4] A collapsed lung can result when the pleural cavity (the space outside the lung) accumulates blood or air (pneumothorax) or both (hemopneumothorax). These ...
A lung illustration depicting a pulmonary embolism as a thrombus (blood clot) that has travelled from another region of the body, causes occlusion of the pulmonary bronchial artery, leading to arterial thrombosis of the superior and inferior lobes in the left lung: Specialty: Hematology, cardiology, pulmonology, Emergency medicine: Symptoms
Acquired risk factors include the strong risk factor of older age, [5] which alters blood composition to favor clotting. [59] Previous VTE, particularly unprovoked VTE, is a strong risk factor. [60] A leftover clot from a prior DVT increases the risk of a subsequent DVT. [61]

Surgical or catheter embolectomy is a procedure performed in patients with pulmonary embolism, which is a blockage of an artery in the lung caused by a blood clot. This procedure is typically used for patients who are in a critical condition, such as those who are experiencing persisting shock despite receiving supportive care, and who have an ...
Example of a CTPA, demonstrating a saddle embolus. The white area above the center is the pulmonary artery, opacified by radiocontrast. Inside it, the grey matter is blood clot. The black areas on either side are the lungs, with around it the chest wall.
Assuming a normal circulation, an embolus formed in a systemic vein will always impact in the lungs, after passing through the right side of the heart. This will form a pulmonary embolism that will result in a blockage of the main artery of the lung and can be a complication of deep-vein thrombosis .
