Data sharing not applicable to this article as no datasets were generated or analysed during the current study. Videoclip S1 Transvaginal grayscale ultrasound sagittal sweep of lower uterine segment (left to right), showing boomerang vessel arising from placenta, running down along left lateral wall to reach internal cervical os, and then turning and running back along right lateral wall to reach placenta. In midsagittal plane, cross-section of vessel looks like a bubble and along lateral walls, it looks like two parallel lines, as described in literature3.
