Studies show that all of these issues can arise from lying in the supine position during late pregnancy, which can cause compression and obstruction of the inferior vena cava by the uterus. [1] Symptoms of late pregnancy inferior vena cava syndrome consist of intense pain in the right hand side, muscle twitching, hypotension , and fluid retention.
During pregnancy, the enlarged abdomen and gravid uterus place additional strain on lumbar muscles and shift the pregnant woman's center of gravity. These postural compensations culminate in an increased load on both lumbar spinal musculature and the sacroiliac ligaments, manifesting as low back pain and/or pelvic girdle pain. [14]
Aortocaval compression syndrome, also known as supine hypotensive syndrome, is compression of the abdominal aorta and inferior vena cava by the gravid uterus when a pregnant woman lies on her back, i.e. in the supine position.
Other causes are acquired, such as cervical stenosis, intrauterine adhesions, endometrial cancer, and cervical cancer. [ 3 ] 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 ...
Uterine distention caused by things like more than one fetus present, polyhydramnios, fetal macrosomia, uterine fibroids, chorioamnionitis can also lead to decreased uterine function and atony. Retained placental tissue or placental disorders, such as an adherent placenta, placenta previa , and abruption placentae increase the mother's risk of PPH.
Uterine prolapse is a form of pelvic organ prolapse in which the uterus and a portion of the upper vagina protrude into the vaginal canal and, in severe cases, through the opening of the vagina. [4] It is most often caused by injury or damage to structures that hold the uterus in place within the pelvic cavity. [ 2 ]
According to Oller, “With uterine didelphys there is a higher risk of miscarriage, preterm labor, breech presentation, the need for a Cesarean section, pregnancy-associated hypertension, lower ...
In 2015 about 6.5 million cases of obstructed labour or uterine rupture occurred. [5] This resulted in 23,000 maternal deaths down from 29,000 deaths in 1990 (about 8% of all deaths related to pregnancy). [2] [6] [9] It is also one of the leading causes of stillbirth. [10] Most deaths due to this condition occur in the developing world. [1]
