What are the causes of poor healing of uterine incision?

Poor healing of uterine incision often brings a lot of trouble to patients. Poor healing of uterine incision can cause heavy bleeding in the late pregnancy, damage the patient's uterus, and severely threaten the patient's life. It is a very dangerous disease for female friends. Poor healing of uterine incision is so dangerous, so how can we know what causes poor healing of uterine incision? Today we will talk about the reasons for poor healing of uterine incision?

1. Related to the anatomy of the lower uterine segment. The arcuate arteries in the lower segment and isthmus of the uterus are shorter and smaller with fewer branches than those in the uterine body. Therefore, when performing a cesarean section through a lower transverse incision, the downward oblique uterine artery branches are often cut off, resulting in insufficient blood supply to the incision, especially at the lower edge of the incision, causing poor incision healing.

2. The presenting part of the delayed fetus compresses the lower part of the uterus for a long time, causing local ischemia, edema, increased tissue fragility, and incision tearing. In one case in this group, due to prolonged labor, the cervix was fully opened and it was difficult to remove the head by cesarean section, resulting in incision tearing and bleeding.

3. The height of the transverse incision. Because the tissue of the isthmus of the uterus is similar to that of the body of the uterus, it is mainly muscle tissue and has good healing ability; while the tissue of the cervix of the uterus is mainly fibrous tissue, with muscle cells accounting for only about 10%, and has poor healing ability. Therefore, if the incision is made near or on the cervix, its healing ability will be poor, which may easily lead to wound ischemia, infection, and tissue necrosis.

4. Suturing methods and sutures. In all 5 cases reported here, the myometrium was sutured continuously in two layers using No. Ⅰ chromic catgut. Some authors have confirmed through animal experiments that poor healing of lower uterine segment cesarean section incisions is related to this suture method. It is now changed to single-layer continuous lock-edge stitching.

5. Infection problems. Pathological examination of the 5 cases in this group confirmed that there were a large number of inflammatory cells infiltrating the uterine muscle wall, especially at the incision site.

The above are the reasons for poor healing of uterine incision. Therefore, doctors should improve the quality of surgery and control the time of surgery. They should have a balanced nutrition after surgery, improve the body's resistance, and strengthen personal hygiene after surgery. As long as these are implemented, I believe that poor healing of uterine incision will occur less and less. I hope the reasons we collected will be helpful to you.
