Figure legends CAT
FIGURE 1: (a) Two-dimensional image showes that the main pulmonary artery originated from the left side of the arterial trunk.(b) STIC image showing the main pulmonary artery originating from the left side of the arterial trunk. CAT: common arterial trunk, PA: pulmonary artery, MPA: main pulmonary artery, LPA: left pulmonary artery, RPA: right pulmonary artery.
FIGURE 2: (a) Two-dimensional image shows that the left and right pulmonary arteries originate behind the arterial trunk, respectively. (b) STIC image showing the left and right pulmonary arteries originate behind the arterial trunk, respectively. AO: aorta, TA: arterial trunk, RPA: right pulmonary artery, LPA: left pulmonary artery.
FIGURE 3: (a) Two-dimensional ultrasound shows that the left pulmonary artery originates from the arterial trunk and the right pulmonary artery is supplied by the ductus arteriosus.(b) STIC image showing the left pulmonary artery originates from the arterial trunk and the right pulmonary artery is supplied by the ductus arteriosus. LV: left ventricle, RV: right ventricle, Tr: trunk, LPA: left pulmonary artery, RPA: right pulmonary artery, DA: ductus arteriosus.
FIGURE 4: (a) Two-dimensional ultrasonography and CDFI of the three-vessel tracheal section showed that the left subclavian artery was interrupted in the distal aortic arch, and the right subclavian artery originated from the origin of the descending aorta.(b) STIC shows that the arterial trunk divides into the pulmonary artery and the ascending aorta, and the right subclavian artery arises from the origin of the descending aorta. AAO: ascending aorta, PA: pulmonary artery, Tr: trunk, DA: ductus arteriosus, DAO: descending aorta, ARSA: aberrant right subclavian artery.
