Figure 2. Left, transverse view of the thoracostomy tube (TT) using the linear transducer. The TT appears as a thinly curved echo with shadowing (double white arrow). A rib can be seen adjacent to the TT with a hyperechoic curved echo with shadowing (thick white arrow). In this image, a pleural effusion is also seen (thick short arrow) as well as the visceral pleura (thin white arrow). Right, longitudinal view of the TT using the linear transducer. The TT appears as a linear anechoic structure that courses through the subcutaneous tissues and into the pleural space (double white arrow). The visceral line is also seen (thin white arrow).
