The lining of the uterus can be likened to an alluvial field, a fertile alluvial field is provided with nutrients and water, the plants will be lush. Endometrial doppler ultrasound, uterine lining ultrasound have helped doctors orientate and have a good prognosis in finding the cause of implantation failure: endometrial hyperplasia, endometrial polyps , uterine fibroids, or uterine malformations, uterine adhesions, cesarean section defects, and uterine fluid.
With a high quality ultrasound result at Vinmec IVF center, it will help doctors make the right decision for embryo transfer or hysteroscopy to diagnose and intervene: polyp removal, removal of uterine adhesions.

Transvaginal ultrasound of the uterus and ovaries is a routine assessment of the structure of the uterus - ovaries, especially important to monitor the growth of the uterine lining (NMTC) for decision and prognosis. embryo transfer.
Previously, the factors to determine a good endometriosis were the thickness of the endometrium (minimum 7mm), and endometrial morphology: tricuspid/coffee bean shape.
However, during the follow-up period, there were failed embryo transfer cases where the NMTC was still thick enough, 3 leaves. So, what is the doctor's strategy to get these patients pregnant?
One of the factors related to the implantation of the fetus will be a team of experienced doctors performing doppler ultrasound to assess endometrial perfusion, ultrasound survey of the uterus with a modern ultrasound system.

Endometrial doppler ultrasound is a transvaginal ultrasound of the uterus and ovaries that uses a color doppler to evaluate the blood flow to the lining of the uterus waiting for embryo implantation. Perfusion grade (types I, II, III) of the uterine lining is given only when the uterine lining reaches 7 mm or more, and there are favorable factors such as: uterine position, ultrasound machine, doctor experienced doctor. Ultrasound examination of the uterus: is a transvaginal ultrasound of the uterus - ovaries that uses vertical, horizontal, and horizontal sections to build 3D and 4D shapes to detect ovarian diseases. uterine polyps, uterine adhesions, uterine fibroids, and especially uterine malformations such as unicornuate uterus, septate uterus, double uterus...

The receptivity of the endometrium is an important factor for embryo implantation. It is agreed that both endometrial thickness and endometrial morphology are useful as prognostic parameters for successful pregnancy in embryo transfer. Sufficient perfusion to the endometrium is crucial for embryo implantation.
At IVF Center - Vinmec 100% of cases of preparation of the uterine lining for transfer of fresh or stored embryos are applied with doppler ultrasound of the uterine lining. In addition to using doppler waves to evaluate mucosal perfusion, during the examination of the uterus, the uterus is also evaluated and investigated for morphology, the occurrence of factors detrimental to the implantation process. , or detect uterine malformations, cesarean section scars, uterine fluid... that were not detected before.
In a statistical report at Vinmec IVF center in 2017, the pregnancy rate in the group of patients with doppler endometriosis type II, type III is much higher and statistically significant compared to the group with doppler endometriosis type. I.
In another retrospective study at the IVF center, Vinmec hospital, it was found that 90% of patients with ultrasound examination of the uterus and detected uterine pathology were correctly diagnosed by laparoscopic surgery: uterine polyps, uterine adhesions, uterine malformations, endometriosis just below the uterine lining...

Thus, ultrasound examination of the uterus is a non-invasive, low-cost, and highly effective method for patients.
Therefore, doppler ultrasound - uterine survey is an effective strategy to help find the cause of implantation failure in IVF.
Below is an illustration of a doppler ultrasound - survey of the uterus
