Presentation transcript:

Normal 6- to 7-week IUP. A: Magnified TV sonogram of 3-mm embryo/yolk sac (arrow). Compare to Figure 3-1H. B: TV sonogram of 6-week IUP with 6-mm embryo (between x’s) adjacent to the yolk sac. C: Magnified TV scan of 6-week IUP demonstrating embryo within embryonic cavity (1), extraembryonic coelom (2), and yolk sac (3). D: Magnified TV sonogram of 6-week IUP demonstrating embryo/yolk sac complex and decidua capsularis and vera. Compare to Figure 3-1L. E: Yolk sac/embryo surrounded by choriodecidual layers. F: TVS showing embryo/yolk sac complex. The embryo is 3 mm in size, and heart motion was seen. G: TVS of “deflated” gestational sac with enlarged yolk sac but no definite embryo. This is consistent with embryonic demise. H: Five- to six-week IUP in a bicorunate uterus. H(a): Transverse TVS showing gestational sac in right horn of a bicornate uterus. H(b): Sagittal TVS through left nongravid horn. H(c): Sagittal TVS through right horn with gestational sac.
