luteal hematoma
Introduction
Introduction to luteal hematoma The corpus luteum hematoma is a normal ovulation process, the follicular layer ruptures, causing hemorrhage, and more blood is retained in the follicle or the corpus luteum to form a hematoma. basic knowledge The proportion of illness: 0.001% Susceptible people: no special people Mode of infection: non-infectious Complications: irregular menstruation female infertility
Cause
Cause of corpus luteum hematoma
After ovulation, the follicular membrane ruptures, causing hemorrhage, and blood is retained in the follicle or the corpus luteum to form a hematoma.
Prevention
Luteal hematoma prevention
1. Avoid cold during menstruation.
2, pay attention to reproductive health and avoid inflammation.
3, to maintain a happy spirit, bad mood can lead to inhibition of pituitary function.
4. Moderate life.
5. Eat high-protein foods and ginger soup, lamb, vegetables, and fruits. Drink plenty of water to keep your stools open.
Complication
Luteal hematoma complications Complications, irregular menstruation, female infertility
Luteal cysts, infertility.
Symptom
Luteal hematoma symptoms common symptoms abdominal pain corpus luteum rupture abdominal bleeding
The normal corpus luteum is about 15 mm in diameter, and later turns into a white body, and naturally resolves in the follicular phase of the next cycle. If there is more bleeding in the corpus luteum, a luteal hematoma, or hemorrhage in the corpus luteum, hemorrhagic corpus luteum is formed. The corpus luteum hematoma is mostly unilateral, generally 40mm in diameter, even up to 100mm. The corpus luteum hematoma can cause corpus luteum cysts after absorption. Larger hematoma rupture can occur intra-abdominal hemorrhage, severe abdominal pain, a small amount of vaginal bleeding and peritoneal irritation. Not easy to distinguish from ectopic pregnancy.
1. In the early stage of luteal hematoma, when there is more intracapsular hemorrhage, it is characterized by a nearly round cyst in the ovary, a thick wall of the capsule, a rough inner wall, a disordered low echo in the capsule, and a variety of echoes. (sometimes a near-uneven solid echo)
2. In the middle stage of luteal hematoma, the blood in the corpus luteum is coagulated, partially absorbed, the wall of the capsule is thinned, the inner wall is smooth, and the echo in the capsule is reduced, showing a coarse mesh and a fine mesh structure. (Intensive dot echoes are also visible in the capsule)
3, late luteal hematoma, cysts become smaller after blood absorption, into white body, internal echoes are slightly higher echoes, and the surrounding ovarian tissue is unclear, face by color ultrasound shows its surrounding annular blood flow judgment, when the blood is completely After absorption, a corpus luteum cyst is formed, the wall of the capsule becomes smooth, and there is no echo in the capsule, which is indistinguishable from other cysts of the ovary.
4, CDFI: luteal hematoma or corpus luteum cystic color Doppler performance is characteristic, in the medulla of the corpus luteum near the ovary can be seen a supply of blood vessels, radial branches to the corpus luteum wall, color Doppler or energy Doppler blood map The circumference of the corpus luteum shows a circular or half-circle blood flow signal.
Examine
Examination of corpus luteum hematoma
1. Color ultrasound examination;
2, gynecological examination;
3, laparoscopy.
Diagnosis
Diagnosis and differentiation of corpus luteum
Luteal hematoma needs to be differentiated from solid ovarian tumors:
The corpus luteum hematoma is complicated and variable due to its different amount and time of bleeding. Especially the large early hemorrhagic corpus luteum is easily misdiagnosed as ovarian solid tumor. When misdiagnosed as ovarian solid tumor, the corpus luteum rupture sonogram is not easy to distinguish from ectopic pregnancy, and can be identified according to the menstrual cycle and urine HCG. When the early hemorrhage is more, it is a round cyst in the ovary. The capsule is thick and the inner wall is rough. The cyst is mostly heterogeneous, low echo or fine mesh, and coarse mesh structure. This period of luteal hematoma is easily misdiagnosed as a ovarian neoplastic tumor. At this time, according to the menstrual cycle and blood
The flow distribution features are identified.
The color ultrasonographic manifestations of corpus luteum hematoma have its characteristics. Around the corpus luteum, a circle or half circle of blood flow signals can be seen, which is easy to record into the blood flow spectrum. The early blood flow velocity of the corpus luteum is high, up to 20-20 cm/s. Diastolic components are rich, blood flow resistance is low, RI can also be reviewed in a short period of time. If there is continued bleeding, the mass can be enlarged first, and the sonogram is a coarse mesh structure, which is more bloody, and the blood coagulates into a blood clot. After the corpus luteum blood is absorbed, the cyst becomes smaller, usually 25 to 30 mm in diameter, which is difficult to distinguish from ovarian cysts. Some of them are due to the loss of luteinizing hormone, corpus luteum atrophy, increased intraluminal fibrous tissue, and converted into white body. The sonogram of corpus luteum hematoma becomes unclear, and the internal echo is slightly higher than the echo, which disappears after the next menstrual clean.
In summary, the sonogram of the corpus luteum hematoma is manifested by its hemorrhage. The different sonograms of the corpus luteum are complicated and variable, but there are still certain rules to follow. The key to the diagnosis is to fully understand the characteristics of the corpus luteum hematoma. Internal review, changes in the sonogram to support the diagnosis of corpus luteum hematoma. Ultrasound, a non-invasive method of examination, can be repeated and dynamically observed to reduce the rate of misdiagnosis.
Ultrasound performance: According to the amount and time of hemorrhage of the corpus luteum, the sonogram is diversified.
