“…However, CEUS has been reported to enable the detection of perfusion changes and extravasation of blood [5], and it is increasingly used when active abdominal bleeding is suspected, in particular in a trauma setting [6,7]. Furthermore, some reports suggested that CEUS could also represent an interesting tool in the detection of active bleeding outside the abdominal cavity [8][9][10], and the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) guidelines suggested that CEUS may detect an ongoing hemorrhage and is useful in monitoring all stages of post-procedure bleeding [11,12]. However, to our knowledge, CEUS has never been reported to enable not only the depiction of a bleeding but also the real-time demonstration of the spontaneous stop of the bleeding, as shown in this case in which CEUS played a key role in both settings.…”
