Uterine disease and habitual abortion

Repeatability abortion and the uterine diseases, abortion repeatedly about the 15%. Uterine disease -- a classification. Uterine congenital dysplasia of human uterus is the vice renal tube development Evolution of organ formation. Bilateral lumen incomplete fusion, or the integration of the mediastinum not absorbed or incomplete absorption may lead to uterine malformations. Varying degrees of septate uterus is the most common deformity vulnerable to early abortion. Other single-uterine horn, Bicornuate and double uterus, they can lead to abnormal implantation of gestation, the impact of the placenta, fetal development where abortion. 2. Asherman repeatedly for abortion, excessive curettage. Intrauterine surgery and pregnancy-stranded as a result of injury and infection can cause uterine adhesions. Asherman patients about 14% risk of miscarriage. Go adhesions caused rhetoric, deformation and endometrial reduction, endometrial function of the damaged layer. implantation of the embryo can be influenced by the development and lead to miscarriage. 3. Uterine fibroid uterine fibroids and abortion depends on the relationship between the types of fibroids, the location, size and the availability of secondary changes. So submucosal uterine myoma deformation, endometrial surface often formed in the shallow ulcers, the implantation and gestation impact development, fibroids obstructive role in the endometrium and myometrium vasodilators, congestive, reduced blood flow and is not conducive to embryonic development. In addition, the partial pressure of fibroids, uterine deformation and degeneration caused contraction of the uterus where abortion. 4. Cervical dysfunction cervical dysfunction performance is largely premature and, repeatability late abortion repeated abortion rate of 8% to 15%. (1) of congenital cervical dysfunction : about 1 / 3 of patients with cervical incompetence caused by congenital factors. accompanied Müllerian developmental abnormalities, such as single-uterine horn or septate uterus, cervix may also be histological defects cervical elastic protein content inadequate. (2) acquired cervical dysfunction : often occurred in obstetric or gynecological surgery after injury, as rowdy crowd at the Palais I dilatation, resection of cervical cone and childbirth cervical laceration suture not timely; also in the secondary uterine cervix or lower part of the anatomy changes, the case of fibroids. (3) cervical physiological dysfunction : Some scholars believe that within the cervix during pregnancy mouth with functional sphincter, Asian clinical contraction of the uterus or cervix low tension within the mouth of patients with cervical I sphincter weakened role. In addition, Bromelain and papain can cervical relaxation. Cervical dysfunction, can not afford an increase in pregnancy with intrauterine pressure increased, frequently used in the second trimester amniotic since the break occurred while abortion may be discharged completely normal embryonic tissues. ??-- A diagnosis. Congenital abnormalities and uterine Asherman, uterine fibroids can be used ultrasound, Hysterosalpingography. Hysteroscopy, or laparoscopy. Without the above conditions or expanding the probe can be used for diagnosis of the Palais heavier adhesion of mediastinal or deformity. 2. Cervical insufficiency (1) history : history is typical of advanced natural membranes rupture, soon after childbirth out completely normal fetuses, but each pregnancy than previous pregnancy in premature labor. (2) cervical screening : Non cervical palpation during pregnancy, cervical isthmus short but relatively relaxed. 8-Hegar expander can be passed without resistance cervical mouth for the diagnosis of cervical incompetence simple method. (3) Foley catheter traction test : Add intrauterine Foley catheter. Wizard of intraarticular injection into the water was tube-fed, it 6mm diameter, this can easily be pulling out of intrauterine I (traction less than 600mg) can be suspected cervical incompetence. should further diagnosis. (4) Hysterosalpingography : It is reported that under normal circumstances the uterine isthmus average diameter of 2.63mm. but cervical incompetence were isthmus average diameter increased significantly, uterine cervix under the control of the angle disappeared. (5) Ultrasonic Inspection : abdomen, perineum or vaginal ultrasound during pregnancy is the diagnosis of cervical incompetence most common and effective method. Second-trimester cervical diameter less than 19mm be excluded from cervical incompetence, and ≥ 23 mm in diameter can be determined diagnosis. Membranes were beak - or funnel-shaped mouth into the cervix is diagnosed with cervical incompetence of the ultrasound image, this levy appears shortened cervix before. Cervical length of> 30mm normal; Length <20mm>
