Symptoms Pulmonary Infarction

What Is Pulmonary Infarction: Cause And Symptoms

Pulmonary infarction is a relatively frequent complication of pulmonary embolism (it affects approximately 10% of patients who suffer from this pathological condition). The obstruction of a pulmonary artery by an embolus (usually a blood clot resulting from thrombosis of the veins of the lower limb , such as the saphenous or femoral veins) can in fact lead to necrosis of the blood-deprived lung tissue, therefore of oxygen and nutrients . This event, called pulmonary infarction, is not particularly frequent because the pulmonary circulation is strongly anastomosed with the bronchial arterial network, of systemic origin, normally capable of supplying blood to the tissues downstream of the obstruction (there are numerous vascular bridges, therefore natural bypasses). Furthermore, the lung parenchyma benefits from direct oxygenation guaranteed by alveolar ventilation .In addition to patients predisposed to deep vein thrombosis, pulmonary infarction is more frequent in patients with heart disease (left heart failure, mitral stenosis), COPD , tumors, severe atherosclerosis or hematological disorders (e.g. sickle cell anemia ).

The symptoms of pulmonary infarction include the sudden onset of a violent stabbing pain in the chest, which is accentuated with breathing and coughing ( pleural-type pain), as well as dyspnea , tachypnea , cyanosis and cough with hemoptysis or hemophtoe (expectoration of material consisting almost entirely of mucus and blood) and fever .

Lung infarction may resolve with resorption and fibrosis (formation of scar tissue) or with complete resorption that leaves normal lung tissue (incomplete infarction). In itself, pulmonary infarction has a good prognosis, which is however affected by the possible appearance of complications and the underlying disease that generated it.
