Cesarean Scar Pregnancy

## Cesarean Scar Pregnancy

A Cesarean scar pregnancy (CSP), also known as a scarred uterus pregnancy and cesarean scar implantation, is a rare complication of a previous cesarean section (C-section) where a fertilized egg implants in the lower uterine segment or the previous cesarean scar.

### Symptoms of CSP

Women with CSP may develop symptoms similar to other pregnancy-related complications, such as:

– Abdominal cramping
– Low backache
– Vaginal bleeding
– Abdominal or pelvic pain

### Causes of CSP

It is believed that CSP occurs when the placenta, the organ which attaches a baby to the uterine wall and supplies nutrients to it, places itself in the previous C-section scar instead of the upper uterine wall. This can happen when the endometrial lining (the lining of the uterus which thickens to prepare for implantation) is too thin to hold the placenta.

### Risks Factors of CSP

A CSP is a rare but serious complication in pregnancy. The following factors are associated with an increased risk of CSP:

– Previous Cesarean section
– Use of IVF or assisted reproductive technologies
– Increased parity (having more than 1 pregnancy)
– History of uterine fibroids or adhesions

### Detection of CSP

If you have had a previous C-section, your doctor will likely monitor you closely for any signs and symptoms of CSP. Ultrasound, a non-invasive imaging technique, is usually used to diagnose CSP. An ultrasound can detect the presence of a neovascularization (new blood vessels) in a prior Cesarean scar, which is an indication of CSP.

### Treatment of CSP

Treatment of CSP depends on the duration and type of pregnancy. If the pregnancy is in the first trimester, the treatment of choice is usually expectant management (waiting and monitoring) or termination. Progesterone supplementation is used to reduce the risks associated with CSP.

In the second and third trimester, treatment for CSP may include:

– Cesarean delivery
– Watchful waiting with regular ultrasound and Doppler studies
– Vaginal delivery, depending on the location of the placenta
– Preterm delivery in cases where the placenta or scar is deemed too fragile for delivery

### Conclusion

Cesarean scar pregnancies are rare but potentially dangerous complications of a previous C-section. Early detection and proper management are necessary to ensure optimal outcomes for mother and baby. It is important for women who have had a prior cesarean section to be aware of the warning signs and symptoms of CSP and to speak to their health care provider if they experience any of them.
