Histopathology of a pulmonary artery with fat embolism (seen as multiple empty globular spaces on this H&E stain since its processing dissolves fat). There is a bone marrow fragment in the middle, and multiple single hematopoietic cells in the blood, being evidence of fracture as the source of the embolism.
The pulmonary embolism rule-out criteria (PERC) helps assess people in whom pulmonary embolism is suspected, but unlikely. Unlike the Wells score and Geneva score , which are clinical prediction rules intended to risk stratify people with suspected PE, the PERC rule is designed to rule out the risk of PE in people when the physician has already ...
Bronchial artery embolization is a treatment for hemoptysis, abbreviated as BAE. It is a kind of catheter intervention to control hemoptysis (airway bleeding) by embolizing the bronchial artery, which is a bleeding source. Embolic agents are particulate embolic material such as gelatin sponge or polyvinyl alcohol (PVA), and liquid embolic ...
[22] [24] A point-of-care echocardiogram can also assess for causes of obstructive shock. The vena cava would be dilated due to the obstruction. In pulmonary embolism, the right ventricle will be dilated. Other findings include paradoxical septal motion or clots in the right heart or pulmonary artery. Echocardiography can assess for pericardial ...
The term embolus refers generally to any free-floating mass in the bloodstream. A related term is embolism, which describes the phenomenon of an embolus lodging in a vessel and creating a blockage. [2] An embolism is technically a consequence of an embolus, but the terms are sometimes used interchangeably. [6]
A multiplace chamber is the preferred facility for treatment of decompression sickness as it allows direct physical access to the patient by medical personnel, but monoplace chambers are more widely available and should be used for treatment if a multiplace chamber is not available or transportation would cause significant delay in treatment ...
Venous thrombosis can lead to pulmonary embolism when the migrated embolus becomes lodged in the lung. In people with a "shunt" (a connection between the pulmonary and systemic circulation), either in the heart or in the lung, a venous clot can also end up in the arteries and cause arterial embolism. [citation needed]
An embolism can cause ischemia—damage to an organ from lack of oxygen. [1] A paradoxical embolism is a specific type of embolism in which the embolus travels from the right side of the heart (venous circulation) to the left side of the heart (arterial circulation) and lodges itself in a blood vessel known as an artery.
