Lung infarction or pulmonary infarction occurs when an artery to the lung becomes blocked and part of the lung dies. [1] It is most often caused by a pulmonary embolism . Because of the dual blood supply to the lungs from both the bronchial circulation and the pulmonary circulation , this tissue is more resistant to infarction .
Lung complications, such as pulmonary contusion and pulmonary edema, may result from other aspects of PCAS such as CPR and left ventricular dysfunction, respectively. Finally, pneumonia is a common pulmonary complication due to multifactoral mechanisms including: loss of airway protection, aspiration, emergency intubation, and mechanical ...
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 ...
Spinal Cord Infarction after Bronchial Artery Embolization for Hemoptysis: A Nationwide Observational Study in Japan - This study used Japan's DPC healthcare database to determine the incidence of spinal cord infarction after BAE, revealing a rate of 0.19%. The incidence varied depending on the embolic material, with significantly lower rates ...
It is used in ST elevation myocardial infarction, stroke, and in cases of severe venous thromboembolism (massive pulmonary embolism or extensive deep vein thrombosis). [citation needed] The main complication is bleeding (which can be dangerous), and in some situations thrombolysis may therefore be unsuitable.
Infarction occurs as a result of prolonged ischemia, which is the insufficient supply of oxygen and nutrition to an area of tissue due to a disruption in blood supply.The blood vessel supplying the affected area of tissue may be blocked due to an obstruction in the vessel (e.g., an arterial embolus, thrombus, or atherosclerotic plaque), compressed by something outside of the vessel causing it ...
Possible complications of arterial embolism depend on the site of the obstruction: In the heart it can cause myocardial infarction [2] In the brain, it can cause a transient ischemic attack (TIA), [2] and, in prolonged blood obstruction, stroke. [2] Blockage of arteries that supply arms or legs may result in necrosis and gangrene [1]
Complications: If reversed, coma, persistent vegetative state, post-cardiac arrest syndrome; if not reversed, death: Usual onset: The risk of onset increases with age [3] Causes: Coronary artery disease, congenital heart defect, major blood loss, lack of oxygen, electrical injury, very low potassium, heart failure, myocardial infarction ...
