Required, human blood circulation: left apical artery Jeffery capillary Bellow vein Owens capillary "Barrow Vehicle" Under normal circumstances, the thrombus from the vein to the right atrium will not reach the left heart because it will Blockage in the lungs. An abnormal thrombus enters the left heart through an undiagnosed foramen ovale. When I was six months old, I took my child to take the test, but the test was not over yet. According to doctors, it seems that depending on where it is, some positions will close on their own as they grow older, and some may require surgery. But the cost of the surgery will be borne by the state.
Oval patent generally does not require treatment, and subsequent treatment is also possible. Patented feed UFOs depend on whether other aspects of the heart's structure are normal. For example, there are no other complex congenital diseases. Other structures of the heart were normal. As long as you comply, you can retest your mid- to mid-term ultrasound in one or more years. The foramen ovale is a small hole in the septum between the left and right rooms, which connects the left and right atria during fetal life. After birth, normal FOI pulmonary circulation is established, intra-atrial pressure increases, and the valve of the fossa ovale presses against the edge of the fossa ovale to form a functional closure. Anatomically complete closure should wait until 5-7 months after birth.
Fetal oxygen is provided by the placenta. Blood from the placenta enters the right atrium and right ventricle and flows into the left atrium through the feeding oval. The blood in the left atrium provides nutrition to the whole body through the aorta. When the umbilical cord is disconnected, the blood no longer passes through the umbilical cord, but enters the lungs through the pulmonary artery in the right ventricle for oxygenation, and then the foramen ovale gradually closes. It does not affect development. It is normal for babies to have foramen ovale before one year old. The foramen ovale is an essential life passage for fetal development. It is through this channel that blood from the mother's umbilical vein enters the left heart cavity of the fetus and is then distributed throughout the body to provide oxygen and nutrients for fetal development.
Under normal circumstances, it can be completely closed after 7 months to 1 year. After 1 year, you can go to a tertiary hospital to check the color of Doppler echocardiography. If it is not closed, the gap is relatively large and requires surgical repair. During fetal life, the oval is a small hole in the septum between the left and right rooms, i.e. Blood from the left atrium and right atrium are connected during fetal life to maintain fetal blood circulation. Anatomical closure is usually completed within the first year of life. If the ovoid feed has not closed in a child over three years of age, it is called a male ovoid patent.
