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 .
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 ...
Obstruction can occur at the level of the great vessels or the heart itself. [2] Causes include pulmonary embolism, cardiac tamponade, and tension pneumothorax. [3] These are all life-threatening. Symptoms may include shortness of breath, weakness, or altered mental status. Low blood pressure and tachycardia are often seen in shock. Other ...
Unlike the temporary, healing kind, it lingers over time, often quietly wreaking havoc in the background. When inflammation becomes long-term (or chronic), it can start damaging tissues and ...
Pulmonary laceration usually heals quickly after a chest tube is inserted and is usually not associated with major long-term problems. [8] Pulmonary lacerations usually heal within three to five weeks, [12] and lacerations filled with air will commonly heal within one to three weeks but on occasion take longer. [1]
Infant prematurity is the factor most commonly associated with pulmonary hemorrhage. Other associated factors are those that predisposed to perinatal asphyxia or bleeding disorders, including toxemia of pregnancy, maternal cocaine use, erythroblastosis fetalis, breech delivery, hypothermia, infection (like pulmonary tuberculosis), Infant respiratory distress syndrome (IRDS), administration of ...
This is in contrast to wound healing, or partial regeneration, which involves closing up the injury site with some gradation of scar tissue. Some tissues such as skin, the vas deferens, and large organs including the liver can regrow quite readily, while others have been thought to have little or no capacity for regeneration following an injury.
