Figure 1: Sequence of images with high definition ultrasound with a 5-16 Mhz lineal probe in a longitudinal view where the application of the ultrasound-guided EPI® technique in the focus of the hematoma (a) is observed. Upon activating the EPI® the hematoma begins to dissolve with the smoke effect appearing (arrow). After the first 5 seconds of treatment, the MTR® suction system (b) is activated to obtain a complete evacuation of the hematoma, leaving the injury virtually sealed (c).
