Figure 1: Fallopian tube embolization by microcoil. (A) The shape of bilateral fallopian tubes (indicated by black arrows) and the extent of hydrosalpinx are visualized by hysterosalpingography (HSG). (B) Two microcoils (indicated by white arrow heads) are pushed into the bilateral isthmus of fallopian tubes. (C) The fallopian tubes are blocked, as visualized by HSG. (D) The plantium microcoil.
