Intertubal pregnancies and uterine horn pregnancies are both ectopic pregnancies, with the main difference being the site of implantation of the fertilized egg. Intertubal pregnancies are closer to the mucosa of the fallopian tube, whereas uterine horn pregnancies are located on the side of the uterine cavity. Interstitial pregnancy is rare, but due to the thick muscle layer around the lumen of the interstitial part of the fallopian tube and the rich blood flow, once ruptured, it is like a rupture of the uterus, and the symptoms are extremely serious, and the symptoms of hypovolemic shock will appear in a short period of time, which has serious consequences. Horn pregnancy can lead to rupture of the uterine horn, resulting in very serious consequences, and it is difficult to distinguish between the two due to their very similar clinical manifestations. If a pregnant woman is found to have tubal pregnancy or uterine horn pregnancy, it is recommended that she consult a doctor in time, under the guidance of the doctor, complete the relevant examinations to clarify the cause of the disease and treat the symptoms.
