Cervical anterior lip edema
Introduction
Introduction Refers to the phenomenon of edema in the cervix during childbirth. During childbirth, cervical edema is caused by uneven pressure on the cervix and maternal premature breath. Can also be due to poor fetal head flexion, the front top compression of the cervix affects its retraction, resulting in anterior lip edema of the cervix.
Cause
Cause
Causes:
Due to poor fetal head flexion, the anterior top pressing the cervix affects its retraction, resulting in anterior lip edema of the cervix. Usually caused by fetal compression.
Pathogenesis:
The occurrence of cervical edema is related to the tissue composition of the cervix and the anatomy of the pelvis:
(1) At the beginning of the third trimester, the mucopolysaccharide in the matrix of the cervical tissue takes up a lot of water, and the cervical tissue is highly hypertrophied, making the cervical tissue extremely soft. Soft cervical tissue, if stressed, can easily lead to edema. With the expansion of the cervix and the first exposure, the anterior lip of the cervix is sandwiched between the two bone tissues of the fetal head and the pubic symphysis. In addition, the maternal prematurely holds out the breath, so that the incompletely expanded cervix is over-stressed and the blood flow is blocked. As a result, edema and congestion occur. Changes in histology and hemorheology occur in the edema of the cervix.
(2) Cervical vein and lymphatic drainage disorder, leading to vasospasm, tissue hypoxia.

Diagnosis
Differential diagnosis
Cervical anterior lip edema needs to be differentiated from the following symptoms:
1. Cervical softness: The degree of softness and hardness of the female cervix can be used as one of the signs of whether the fetus can be delivered.
2, cervical edema: the expansion and disappearance of the cervix after entering the labor process is not only the result of passive traction, but also caused by its active changes, plays a vital role in childbirth, but due to a series of histochemistry in the cervix during pregnancy And changes in blood rheology make it more prone to edema.
