Usefulness of pulsed Doppler in the ultrasound diagnosis of occult pneumothorax: A case report

Abstract

Here we present the case of a patient who consults for respiratory distress after a traffic accident, where the chest radiography and the usual modes of ultrasound did not allow the diagnosis to be made, while the performance of PW suggested the presence of pneumothorax, which it was subsequently confirmed by chest tomography, considering PW mode it could a complement to the lung ultrasound algorithm to rule out the presence of pneumothorax in order to improve its performance. PW is an easy and quick method to perform, allowing an accurate diagnosis.
