Information on Cesarean Scar Pregnancy
In a CSP the gestational sac and the placenta implant on or within a previous cesarean section scar. The incidence of CSP was estimated to range from 1:1,800 to 1: 2,216 pregnancies9. The main risk factor for CSP is a previous cesarean section. Continuation of the pregnancy is associated with an abnormally invasive placenta.. Women can show signs of profound bleeding and in severe cases rupture of the uterus in the area of the scar. In CSP the invasion of the pregnancy into the myometrium occurs through a defect in the uterine scar on the basis of incomplete healing.
The management of women with CSP is challenging. One of the reasons is that CSP can be misdiagnosed as a low-lying intrauterine pregnancy or a cervical pregnancy. Another reason is that there is no widely accepted treatment modality. Termination of a CSP remains challenging as some treatment modalities fail to terminate the pregnancy or cause excessive bleeding requiring laparotomy and hysterectomy.
