Why is there bleeding after vaginal extravasation?

Vaginal ultrasound refers to ultrasonic ultrasound of the genitals. Many women will have a vaginal ultrasound before and after pregnancy. Some women also experience bleeding after vaginal ultrasound. In such cases, there are many factors to consider. Generally speaking, when a woman has vaginal bleeding, she should take it seriously and also pay attention to conditioning. The relationship between vaginal ultrasound and vaginal bleeding confuses many people. So what happens if there is bleeding after a vaginal ultrasound?

1. Vaginal ultrasound usually does not cause bleeding

Vaginal ultrasound is to insert the ultrasound probe into the vagina. It has a high diagnosis rate for diseases in the adnexal area, especially for those who do not hold urine or have thick abdominal fat. Vaginal ultrasound is often performed without causing vaginal bleeding. Abnormal bleeding is often caused by vaginitis, cervical lesions, and endometrial lesions, so it is necessary for you to have a gynecological examination to see where the blood comes from, and then consider how to deal with it.

2. Dysfunctional uterine bleeding

It often occurs during adolescence and menopause. The length of menstrual period varies, and the amount of blood can be several times the amount of menstrual blood and even cause shock. In contrast, the amount of blood can be continuous. Therefore, the ovarian function in both phases is unstable and most of the bleeding is anovulatory. Patients often experience a period of amenorrhea followed by uterine bleeding. Sometimes it starts with heavy or prolonged menstruation and then turns into irregular or persistent uterine bleeding. Sometimes bleeding can last for more than ten days or longer, and pelvic examination shows no lesions. The basal body temperature is monophasic; the endometrial biopsy shows proliferative endometrium or excessive hyperplasia, which can confirm the diagnosis.

3. Miscarriage

If a woman of childbearing age has had regular menstruation in the past and experiences vaginal bleeding after amenorrhea, early abortion should be considered first. During threatened abortion, there is a small amount of vaginal bleeding, no abdominal pain or mild lower abdominal pain, and early pregnancy reactions. Examination may reveal that the cervix is ​​not open, the size of the uterus is consistent with the month of amenorrhea, and blood and urine pregnancy tests are positive. If the fetus is dead or the cause of miscarriage has not been eliminated, vaginal bleeding increases with paroxysmal uterine pain, and the cervix is ​​open, it should be diagnosed as inevitable miscarriage. If the fetus is expelled but part or all of the placenta remains in the uterine cavity, hindering uterine contraction and causing continuous vaginal bleeding, it is diagnosed as incomplete abortion. Sometimes there may be heavy bleeding or even shock. At this time, the cervix is ​​relaxed and placental tissue can often be seen blocking the cervix. The above types of miscarriage are not difficult to diagnose based on medical history and examination.
