The five characteristics of hymen atresia are four common methods of signal inspection and diagnosis

Hymen is the beauty of young girls, and hymen is also abnormal. hymen atresia is one of them, and there are many abnormal manifestations, which must be checked immediately.

Hymen atresia

1. Delayed menarche: Under normal circumstances, women aged 12-14 years old have menarche. When they suffer from hymen atresia, women have delayed menarche or delayed menarche after puberty.

2. Periodic lower abdominal pain: hymen atresia, resulting in blood accumulation, and periodic lower abdominal pain gradually worsens.

3. There is a lump in the lower abdomen: the lump can be touched in the lower abdomen and increases month by month.

4. External expansion of hymen: during the examination, hymen expands outward, with purple blue surface, and no vaginal opening.

5. Urinary system symptoms: in severe cases, it is accompanied by urinary system symptoms such as constipation, frequent urination, urinary accumulation, constipation, anal expansion, etc.

Pathological characteristics of hymen closure

Many hymen close to puberty without symptoms. After menarche, the hymen is locked and the blood cannot be drained. Initially, menstrual blood accumulates in the vagina. After multiple menstrual cycles, menstrual blood accumulates, and uterine and fallopian tube hematomas are collected and organized by doctors and educational networks. Abdominal hematomas can cause endometriosis and inflammatory changes in the pelvis.

Examination of hymen atresia

1. Gynecological anal examination: prominent hymen, vaginal mass, rectal expansion, uterus enlargement, cystic mass on both sides. Diagnosis is usually based on the above symptoms and signs, without the need for auxiliary examination.

2. Gynecological ultrasonic examination: ultrasonic examination can judge the location and degree of blood accumulation caused by hymen atresia, and estimate the prognosis. Ultrasonic examination is a common method to examine abdomen and perineal organs, and is the most ideal method to examine hymen atresia.

3. Puncture inspection: The thick dark brown or old blood can be drawn from the protruding part of hymen with a thick needle, which is diagnosed as hymen atresia. Puncture biopsy is the main way to obtain pathological diagnosis.

4. Pelvic MRI: MRI can be used to check congenital malformations, and can be used to check whether hymen atresia is caused by congenital malformations. Magnetic resonance has the advantages of high resolution, uniform magnetic field, fast scanning speed, relatively low noise, and multi-directional imaging.

Diagnosis and treatment of hymen atresia

Once confirmed, hymen should be cut as soon as possible to drain accumulated blood, and attention should be paid to the prevention and control of infection. After local anesthesia, puncture the swollen part of the hymen, draw out the brown accumulated blood, cut the hymen into an x shape, remove the excess membrane flap while draining the accumulated blood, and suture the marginal mucosa with 3-0 catgut to keep the drainage smooth and prevent the adhesion of the wound edge. The catheter was retained for 1-2 days on the operation day, and the vulva was scrubbed 1-2 times a day until the accumulated blood was drained.
