Common complications of IVF hemorrhage
IVF (assisted reproductive technology) refers to the cultivation and implantation of fertilized eggs into the mother's uterus for development through in vitro fertilization, embryo transfer and other technologies. Although IVF technology has made remarkable achievements in helping infertile couples realize their reproductive dreams, there are also some risks and complications in the process. One of the most common complications is IVF hemorrhage. This article will introduce the common complications of IVF hemorrhage from four aspects.
Endometrial bleeding
Endometrial bleeding refers to the bleeding phenomenon caused by damage, stimulation or inflammation of the endometrium during embryo implantation. Such bleeding usually occurs within a few days after embryo implantation, and may be accompanied by abdominal pain and vaginal bleeding. The incidence of endometrial bleeding is about 10% to 20%. Although this bleeding is usually self limiting, in some cases, additional treatment may be required, such as local hemostasis measures or drug treatment.
Endometrial bleeding has various causes, which may be related to factors such as the endometrial environment, endometrial abnormalities and implantation techniques. Some hospitals can reduce the incidence of endometrial bleeding by using drugs that promote endometrial stratification in the IVF procedure.
Ovarian Hyperstimulation Syndrome
Ovarian hyperstimulation syndrome (OHSS) is a serious complication of IVF. It usually occurs after injection of ovulation promoting drugs and is characterized by ovarian enlargement, fluid retention and blood concentration. This condition may cause severe symptoms such as abdominal distension, dyspnea, chest pain and abdominal pain.
Although the incidence of OHSS is relatively low, it is a very dangerous complication for patients. Some hospitals take measures to reduce the risk of OHSS, such as monitoring the dosage of drugs during ovarian stimulation, using new generation ovulation promoting drugs and frozen embryo transfer.
Ectopic pregnancy
Ectopic pregnancy is another serious complication of IVF. It refers to the development of ectopic pregnancy from embryos implanted outside the uterus. Ectopic pregnancy may occur in the fallopian tube, ovary, abdominal cavity or other organs. This situation may lead to serious risks such as internal bleeding, abdominal pain and ectopic pregnancy rupture.
In order to prevent the occurrence of ectopic pregnancy of embryos, some hospitals will carry out positioning inspection during the process of IVF to ensure that the embryos are accurately implanted into the uterine cavity, and deal with the ectopic pregnancy of embryos in a timely manner when it is found.
Embryo implantation failure
The failure of embryo implantation is one of the common complications in IVF. Sometimes, although the embryo was transferred, it failed to implant and develop successfully. This may be caused by factors such as poor embryo quality, abnormal intrauterine environment or immune response.
In order to reduce the risk of embryo implantation failure, hospitals usually optimize embryo culture conditions, select higher quality embryos for implantation, and conduct appropriate immunomodulation therapy.
Summary
Hemorrhage is a common complication of IVF. Endometrial hemorrhage, ovarian hyperstimulation syndrome, ectopic pregnancy and embryo implantation failure are common complications of IVF hemorrhage. In order to reduce the incidence of these complications, the hospital usually takes a series of preventive measures and treatment methods, such as optimizing the treatment plan, monitoring the patient's condition and regular review. The progress of IVF technology and the standardized operation of hospitals will further reduce the risk of bleeding complications and improve the success rate of IVF.
