In this form oftubal pregnancy, ruptureof the gestation sac maynot take place until muchlater than with the ordi-nary form. Also, therupture may in somecases be into the uterinecavity, so that there isa possibility of this formof tubal pregnancy term-inating as a normal (in-tra-uterine) pregnancy inthe early stages approaches in symptoms and signs very close to normal preg-.

If the place of lodgment of the fertilized happens to be near the outer end of thetube (Fig. 639) the resulting enlargement of the lumen of the tube by the develop-ing embryo, opens the end of the tube, and the embryo with its membranes islikely to be extruded from the end ofthe tube into the peritoneal is called tubal abortion (, 643). Tubal abortion is accom-panied with more or less intraperito-neal bleeding and gives rise to practic-
