Ultrasound Findings of Varices at the Site of Uterovaginal Anastomosis in a Pregnant Woman After Radical Trachelectomy

Complete placenta previa and increta after radical trachelectomy: A case report

Background

Placenta accreta spectrum (PAS) disorders are increasing in incidence and represent a significant contributor to severe maternal morbidity in the US. Prior uterine surgeries other than cesarean section are important, yet less common, risk factors for PAS.

Case

This is a case of a 43-year-old woman with a prior history of cervical cancer necessitating radical trachelectomy. She was subsequently diagnosed with a complete placenta previa with a high degree of suspicion for PAS. Multidisciplinary teams convened to plan for delivery. A cesarean hysterectomy was performed at 32 weeks. Final surgical pathology confirmed the presence of morbidly adherent placenta invading the vaginal cuff.

Conclusion

Patients who are diagnosed with early-stage cervical cancers have the option of fertility-preserving surgical management. Serial ultrasound evaluations, specifically looking for PAS, might be warranted in post-trachelectomy pregnancies.

Fertility-sparing options for cancer patients

Fertility preservation is becoming an integral part of cancer care among women of reproductive age. Despite advances in the treatment of pelvic malignancies, all the currently available treatment approaches, including radiotherapy, chemotherapy, and surgery, place women at high risk for future fertility impairment. With improved long-term survival rates associated with cancer, expanding the reproductive options available is of high priority. Several fertility preservation options are available today for women with gynecologic and non-gynecologic malignancies. Depending on the underlying oncological entity, these can include the following procedures whether alone or in combination: oocyte cryopreservation, embryo cryopreservation, ovarian tissue cryopreservation, ovarian transposition, and trachelectomy. The purpose of this review is to provide the most up-to-date information on the aforementioned fertility-preserving approaches and highlight the current challenges, drawbacks, and areas of research where more data are still very necessary to optimize outcomes in young female oncological patients desiring pregnancy in the future.

Management of pregnancy after radical trachelectomy

Radical trachelectomy (RT) is a surgery for early-stage cervical cancer treatment that preserves the childbearing ability, and its use has become increasingly common worldwide. Thus, the rate of conception in women who have undergone RT is increasing. However, pregnancy after RT is associated with a higher risk of several obstetric complications such as preterm delivery, preterm premature membrane rupture, and abnormal bleeding from varices at the site of uterovaginal anastomosis. Furthermore, since RT have a residual prophylactic cerclage, it is difficult to manage first- and second-trimester miscarriages. There is little previous data on the management of pregnancy after RT. In this review article, we summarize various management methods and experiences to provide a guide to clinicians for perinatal management after RT.
