Incidental Diagnosis of Left Pneumothorax Using a New Variant of the Lung Point Sign During Cardiac Ultrasound.

Background: Pneumothorax is a common issue in the intensive care unit and emergency department, often diagnosed using lung ultrasound. The absence of lung sliding and the presence of the lung point sign are characteristic findings for pneumothorax. We describe a case of left pneumothorax diagnosed incidentally while performing a cardiac ultrasound through a new variant of the lung point sign.

Effect of prone position on right ventricular dysfunction due to pulmonary embolism assessed by speckle tracking echocardiography.

Prone position has shown beneficial hemodynamic effects in patients with right ventricular dysfunction associated with acute respiratory distress syndrome decreasing the right ventricle afterload. We describe the case of a 57-year-old man with right ventricular dysfunction associated with pulmonary thromboembolism with severe hypoxemia that required mechanical ventilation in prone position. With this maneuver, we verified an improvement not only in his oxygenation, but also in his right ventricular function assessed with speckle tracking echocardiography.

Tips for carotid ultrasound in the intensive care unit.

The ultrasonography of carotid arteries plays a key role in evaluating cerebrovascular disease. There are some useful considerations to perform it correctly in the intensive care unit, such as using different kind of transducer, Doppler mode optimization, and the correct interpretation of the findings.

A new approach of non-invasive hemodynamic assessment by echocardiography in the intensive care unit: The right intercostal transhepatic window.

Echocardiography has gained great acceptance in the management of critically ill patients, allowing non-invasive hemodynamic assessment, through conventional cardiac windows such as the parasternal, apical and subxiphoid views. However, it is not always possible to get good quality images because of the interposition of the lung or the presence of surgical drainages at the thoracic region. Based on these issues, we described a case in which echocardiographic assessment was possible through a novel approach: the right intercostal transhepatic window (RITW), through which we diagnosed significant aortic regurgitation in a patient with pulmonary edema.
