Additionally, hematometra may develop as a complication of uterine or cervical surgery such as endometrial ablation, where scar tissue in the endometrium can "wall off" sections of endometrial glands and stroma causing blood to accumulate in the uterine cavity. [1] It can also develop after abortion, [4] as well as after childbirth.
In women of reproductive age, two layers of endometrium can be distinguished. These two layers occur only in the endometrium lining the cavity of the uterus, and not in the lining of the fallopian tubes where a potentially life-threatening ectopic pregnancy may occur nearby. [4] [5] The functional layer is adjacent to the
Amnioinfusion is a method in which isotonic fluid is instilled into the uterine cavity.. It was introduced in the 1960s as a means of terminating pregnancy and inducing labor in intrauterine death, but is currently used as a treatment in order to correct fetal heart rate changes caused by umbilical cord compression, indicated by variable decelerations seen on fetal heart rate monitoring.
The uterine cavity is the inside of the uterus.It is triangular in shape, the base (broadest part) being formed by the internal surface of the body of the uterus between the openings of the fallopian tubes, the apex by the internal orifice of the uterus through which the cavity of the body communicates with the canal of the cervix.
The gestational sac is spherical in shape, and is usually located in the upper part (fundus) of the uterus.By approximately nine weeks of gestational age, due to folding of the trilaminar germ disc, the amniotic sac expands and occupy the majority of the volume of the gestational sac, eventually reducing the extraembryonic coelom (the gestational sac or the chorionic cavity) to a thin layer ...
The uterine cavity is a potential cavity and needs to be distended to allow for inspection. Thus, during hysteroscopy, either fluids or CO 2 gas is introduced to expand the cavity. The choice is dependent on the procedure, the patient's condition, and the physician's preference.
These cells secrete proteolytic enzymes to break down the endometrial extracellular matrix to allow for implantation of the blastocyst in the uterine wall. [26] The blastocoel fluid cavity contains amino acids, growth factors, and other molecules necessary for cellular differentiation. [27]
The Minerva – Endometrial Ablation System, FDA approved in July 2015, is the first new FDA-approved surgical treatment for heavy menstrual bleeding in over 15 years. Minerva works by generating heat from plasma energy that is created and contained inside a leak-proof ablation array that takes the shape of the uterine cavity. The hot membrane ...
