Ovary forms corpus luteum after ovulation. If there is a large amount of fluid in the corpus luteum cavity, which makes the cavity diameter greater than 3cm, it is called corpus luteum cyst. Luteal cyst can cause rupture and bleeding of cyst for some reason, and in severe cases, it can cause acute abdomen [1], especially for young women aged 14 ~ 30. 1 Clinical data 1. 1 Clinical manifestations 1. 1 Symptoms usually occur on the 20th to 27th day of menstrual cycle, with sudden onset of lower abdominal pain, nausea and vomiting, frequent urination, difficulty in defecation, and severe cases of shock. 1. 1.2 signs of anemia, rapid pulse, decreased blood pressure, tenderness of lower abdomen, positive moving dullness, full posterior vault, obvious pain when touching the cervix, and a lump with unclear boundary can be touched on one side of uterus. 1.2 treatment 1.2. 1 conservative treatment is suitable for patients with mild bleeding.

It often occurs under the action of external forces, such as violent jumping, running or impact on the lower abdomen, which can lead to a sudden increase in abdominal pressure and rupture. In addition, during sexual life, the female reproductive organs are dilated and congested, and the tension of the corpus luteum is increased. The man's rude actions will also lead to the rupture of the corpus luteum. Therefore, the above external factors should be avoided and prevented. After leaving the hospital, you must take birth control pills for 3 ~ 6 months continuously, adjust the hormone level, and prevent the corpus luteum from rupturing itself. refer to
