An unusual case of prenatal diagnosis of isolated subaortic left brachiocephalic vein with HDlive flow and spatiotemporal image correlation(STIC)

Prenatal diagnosis of double aortic arch with subaortic left brachiocephalic vein and right-side ductus arteriosus using high-definition flow render mode and spatiotemporal image correlation

Double aortic arch (DAA) with subaortic left brachiocephalic vein (LBCV) and right-side ductus arteriosus (RDA) was not reported before delivery, only in adults with anatomy course findings. We present a case of fetal DAA with subaortic LBCV and RDA using high-definition (HD) flow render mode and spatiotemporal image correlation (STIC).

Prenatal diagnosis of fetal inferior vena cava malformation using HDlive flow combined with spatiotemporal image correlation

OBJECTIVES

This study aimed to examine the application value of high-definition live (HDlive) flow combined with spatiotemporal image correlation (STIC) in the diagnosis of fetal inferior vena cava malformation (IVCM).

METHODS

Twenty cases of IVCMs were diagnosed using two-dimensional HDlive flow and HDlive flow combined with STIC and retrospectively analyzed to examine the impact of using HDlive flow combined with STIC in the diagnosis of IVCM.

RESULTS

HDlive flow combined with STIC detected one case of duplicated IVC, four cases of left IVC (two cases with complex malformations), and 15 cases of interrupted IVC (two cases of isolated IVC disconnection, five cases with left atrial heterogeneous syndrome, and eight cases with other complex malformations).

CONCLUSION

HDlive flow combined with STIC can help in the diagnosis of IVCM, and this technique has important clinical value.
