The lung is a major target organ for acute and chronic complications in sickle cell disease. Acute chest syndrome is the second most common cause of hospital admission resulting in considerable morbidity and mortality. The mainstay of successful treatment remains high quality supportive care. Fluid management, analgesia, oxygenation, bronchodilators, incentive spirometry and judicious use of transfusion therapy are essential elements of supportive care management. Pulmonary hypertension (PHT) has emerged as one of the most frequent and serious complications in these patients. The pulmonary artery pressure should be evaluated periodically by echocardiography. If the PHT diagnosis is positive the use of hydroxiurea, anticoagulation, transfusions and oxygen therapy should be considered. Cardiac manifestations are common including enlargement of the heart, myocardial ischaemia, ventricular dysfunction and cor pulmonale. The management of these complications follows the current guidelines.
