We present hairpin curve tortuous ascending aorta of the fetus using radiant flow and HDlive flow. In a fetus with cystic hygroma and ductus venosus reverse flow at 12 weeks and 6 days of gestation, hypoplastic right ventricle and enlarged right atrium with significant tricuspid regurgitation were noted, and hairpin curve tortuous ascending aorta was evident using radiant flow and HDlive flow. At 17 weeks and 5 days of gestation, chromosome analysis showed Miller–Dieker syndrome [46XY, del(17)(p13.1)]. In another fetus at 21 weeks of gestation, hairpin curve tortuous ascending aorta and dilated pulmonary artery were identified using radiant flow. HDlive flow clearly revealed hairpin curve tortuous ascending aorta, dilated pulmonary artery, and cervical aortic arch. There were no obvious phenotypic features of connective-tissue disorder or other malformation. Tortuous ascending aorta and cervical aortic arch were confirmed after birth. To the best of our knowledge, this might be the first report of hairpin curve tortuous ascending aorta of the fetus with no obvious phenotypic features of connective-tissue disorder.
