Causes of ascites in test tube infants
In vitro fertilization (IVF) refers to the transfer of embryos to the mother's uterus for pregnancy. In some IVF babies, ascites may occur during pregnancy. Ascites refers to the accumulation of excessive fluid in the abdominal cavity of the fetus, which may cause many serious complications. The causes of ascites are related to many aspects. The following four aspects will be described in detail, including fetal problems, pregnancy complications, maternal health and treatment measures.
Fetal problems
A common cause of IVF ascites is the problem of the fetus itself. Congenital heart disease, gastrointestinal tract abnormalities or urinary tract system abnormalities may lead to the accumulation of fluid in the abdominal cavity of the fetus. For example, ventricular septal defect (VSD) in fetal congenital heart defects may lead to cardiac enlargement, thus affecting the heart's blood pumping function and causing the accumulation of pleural fluid and ascites. In addition, fetal gastrointestinal abnormalities such as esophageal atresia, intestinal atresia, etc. may also cause gastric or intestinal fluid to enter the abdominal cavity and cause ascites.
In addition, placental problems are also a factor in IVF ascites. Placental abnormalities lead to intrauterine infection, which leads to fetal edema and pleural effusion. For example, placental abruption, placental infection and other conditions may lead to fetal pleural and peritoneal effusion.
It should be noted that the above fetal problems are not absolute causes, and the specific causes of ascites need to be comprehensively analyzed in combination with specific cases.
Pregnancy complications
There are some differences between IVF pregnancy and natural pregnancy. In the process of IVF, the use of hormones and the operation of IVF technology may increase the risk of complications for pregnant women. Among them, pregnancy complications are also a cause of ascites in test tube babies.
Some pregnancy complications, such as pregnancy induced hypertension syndrome (including pre eclampsia and eclampsia) and gestational diabetes, may lead to edema in pregnant women, and then cause fetal ascites. These complications may cause increased intrauterine pressure in pregnant women, thus affecting the normal function of the placenta and fetus, resulting in ascites.
In addition, infection of pregnant women is also a cause of ascites in test tube babies. Infection during pregnancy, such as urinary tract infection and cervicitis, may cause intrauterine infection, which may lead to the formation of ascites.
Maternal health
Maternal health is also an important factor in IVF ascites. There are some chronic diseases in the mother, such as kidney disease, liver disease, hyperthyroidism, which may lead to ascites in test tube babies.
For example, kidney disease may affect the urination function during pregnancy, thus causing renal pelvis dilatation or urine backflow to the abdominal cavity of the fetus. Liver disease may lead to abnormal liver function, affect water metabolism in the body, and then lead to edema and ascites. Hyperthyroidism causes metabolic abnormalities and increases the risk of accumulation of fetal metabolic waste in the fetal abdominal cavity.
In addition to chronic diseases, bad living habits before pregnancy, such as smoking and drinking, may also have adverse effects on the health of test tube babies and increase the incidence of ascites.
Treatment measures
Treatment of ascites in test tube infants may also lead to ascites formation. When some treatment measures are taken during IVF pregnancy, adverse reactions may occur, which may cause ascites.
For example, in the process of taking out fetal chromosome in the abdominal cavity, amniotic fluid reduction, etc., puncture may damage the abdominal cavity of the fetus, causing fluid accumulation. In addition, the use of hormones and side effects of drugs may also lead to the formation of ascites.
Summary
The causes of test tube baby ascites can be divided into fetal problems, pregnancy complications, maternal health and treatment measures. Fetal problems include heart disease, gastrointestinal abnormalities, etc; Pregnancy complications include hypertension syndrome, gestational diabetes, etc; Maternal health status involves kidney disease, liver disease, hyperthyroidism, etc; Treatment measures may cause adverse reactions. For test tube babies with ascites, professional doctors need to conduct comprehensive analysis according to specific cases and take targeted treatment measures.
