Maternal Care for Cesarean Scar Defect (Isthmocele) (ICD Code: O34.22)

Name of the Condition

• Common name: Isthmocele
• Medical term: Cesarean Scar Defect (CSD)

Summary

Isthmocele is a condition where a niche or defect forms in the uterine wall at the site of a previous Cesarean section scar. This can affect uterine function and may cause various complications in future pregnancies or menstrual cycles.

Causes

• Surgical technique during Cesarean delivery
• Poor healing of the uterine scar
• Consecutive Cesarean sections, resulting in increased scar tissue

Risk Factors

• Multiple Cesarean deliveries
• Short interval between pregnancies
• Infections post-surgery
• Surgical complications during Cesarean section

Symptoms

• Abnormal uterine bleeding, especially post-menstrual spotting
• Pelvic pain
• Infertility or difficulties in conceiving
• Menstrual irregularities

Diagnosis

• Transvaginal ultrasound
• Hysterosonography (saline infusion sonohysterography)
• Magnetic Resonance Imaging (MRI)
• Hysteroscopy

Treatment Options

• Hormonal therapies to manage symptoms
• Surgical repair, including laparoscopic or hysteroscopic correction
• This surgical repair may help alleviate symptoms such as abnormal bleeding and aid in fertility management.

Prognosis and Follow-Up

• Many women successfully manage symptoms with treatment.
• Regular follow-up is important to assess scar stability and potential implications for future pregnancies.

Complications

• Risk of uterine rupture in subsequent pregnancies
• Chronic pelvic pain
• Secondary infertility

Lifestyle & Prevention

• Adequate pregnancy spacing to allow full uterine healing
• Discussion with healthcare provider about delivery options in future pregnancies

When to Seek Professional Help

• Persistent abnormal bleeding
• Severe pelvic pain
• Difficulty in achieving pregnancy after multiple attempts

Additional Resources

• American College of Obstetricians and Gynecologists (ACOG)
• International Urogynecological Association (IUGA)
• Patient support groups for women with post-Cesarean complications

Tips for Medical Coders

• Ensure that the Cesarean scar defect relates specifically to the uterine scar from previous Cesarean deliveries.
• Avoid confusion with other uterine conditions; verify clinical documentation clearly indicates an isthmocele.
