The subsequent fate of tubal pregnancy symptoms is much better understood than its cause. As indicated by studies of the earliest cases tubal pregnancy symptoms, the fertilized egg can be grafted directly to the mucosa or the crease between two pipes or sweet, sending their trophoblast in two folds, and then that, surely, is more common ways of imparting the first two – in the diverticulum, which was formed in the walls of the pipe.
Attach to the mucous folds of the tube or in the lumen of a diverticulum, the fertilized egg to its layer of trophoblast pelvic inflammatory disease, the same way as a normal uterine pregnancy, and slowly dissolves the tissue embedded in it.
Tubal pregnancy symptoms and signs
Implantation in the uterus leads to the egg, immersed in a thick layer of decidua, reaching its trophoblast to the muscle layer of the uterus, stop here and continue its development chorionic villi do not overstep the boundaries of the muscle layer.
In another state of affairs in the case tubal pregnancy symptoms. The mucous tubal pregnancy symptoms does not react during pregnancy decidual change. If the tube and is sometimes found decidua tissue, in any case, it is very poorly developed and may not be used to complete the implantation.
Fine, do not undergo decidual transformation or subjected him to underserved tubal pregnancy symptoms mucosa can not completely ensure the growth of the developing egg here. This leads to the fact that the trophoblast, and subsequently developing it from the villi of chorion, using all of their development opportunities are not limited thickness of the mucosa, but grow in the muscle layer in the direction of a serous cover the pipe.
Growing egg very quickly cease to be placed and gradually stretches the tube that leads to the formation at the site where it develops, fusiform swelling of the tubal pregnancy symptoms, all increase with the eggs.
Tubal pregnancy symptoms
Infiltrating the mucosa and the thickness of the pipe wall, increasing the egg pushes lumen tubal pregnancy symptoms in a direction opposite to the place of implantation. Having a cross-section through such a tube can be observed the following picture: the entire lumen tubal pregnancy symptoms occupied by the growing egg, which pushes toward the periphery of the lumen of the tube, pressed and flattened egg.
Trophoblast eggs, continuing to grow deep into the muscle wall tubal pregnancy symptoms, their peripheral processes, usually serous cover up the pipe and forms are many subtle openings, not leading, however, the pipes to break. In some cases, hidden perforation does not go into the open, because on the surface of the pipe, in place of the hidden break, develops reactive deposition of fibrous tissue, as if warning the possibility of pipe rupture.
The further fate of the eggs is different. Chorionic villi penetrating into the capsule the eggs are subjected to its fibrous tissue degeneration, necrosis and melting, and gradually destroying the capsule up to the surface.
If this process is particularly energetic rupture hidden pipe turns into an open one. Pile tubal pregnancy symptoms are eating serosa, and the blood of the damaged epithelium villi vessels sometimes in large numbers poured directly into the abdominal cavity. In such cases we speak of discontinuities, rather, on the tube perforations.
Perforated pipe is more common in early ectopic pregnancy signs and symptoms periods of an tubal pregnancy symptoms. Perforation is usually small, and the force of bleeding depends on the gap, as sometimes subtle breaks make heavy bleeding.
If, conversely, more actively developing chorionic villi, facing in the direction of the internal capsule, the blood breaks into the egg and turns it into a voluminous blood clot that flows through the gap occurred in the lumen tubal pregnancy symptoms, and hence after an ampoule tube into the peritoneal cavity and then through its uterine end of the uterine cavity.
In what follows, the resulting gap of the internal capsule eggs cuts the pipe walls egg is expelled from his bed and goes to the ampullar part of the pipe and then into the abdominal cavity. This process, which takes place on the usual type of abortion is called a tubal pregnancy symptoms abortion.
Risk of ectopic pregnancy, which developed in the pipe, most often it ends in tubal abortion. Tubal pregnancy symptoms abortion occurs 8 times more frequently than perforation of the tube
