A series of 25 fetuses in which ARSA was diagnosedusing transverse views was found in a group of pregnant women(between 16–36 weeks of pregnancy) attending our Fetal MedicineUnit for ultrasound examination (Figure 1A). After its detection ina transverse view, fetal ARSA was visualized in the coronal view bysweeping the probe at the level of the fetal thorax in a coronal planeanterior to the spine (Figure 1B). In this plane we were able to seethe thoracic descending aorta and the origin of the aberrant vesselin a distal position. Color and Pulsed Doppler was used to definethe course of the ARSA and distinguish it from other vessels.
