Outcome After MTX & Transvaginal Surgery or UAE & Uterine Curettage in Patients With Cesarean Scar Pregnancy

Outcome After MTX & Transvaginal Surgery or UAE & Uterine Curettage in Patients With Cesarean Scar Pregnancy

Cesarean scar pregnancy (CSP)is one of the more serious complications of pregnancies that occur after a prior cesarean delivery. No clinical guidelines have been issued for the management of CSP. More than 30 treatment methods are reported to be used in managing CSP. However, which management can achieve better clinical effects remains unknown. Therefore, this prospective study is designed to compare the outcome between MTX + transvaginal surgery and UAE + D&C in the treatment of CSP.

Inclusion Criteria:

Increased levels of serum β-hCG and ultrasonography findings. The criteria for diagnosis by ultrasonography was the presence of the following: (1) an empty uterine cavity and endocervical canal; (2) detection of the placenta and/or a gestational sac embedded in the hysterectomy scar; (3) the presence of the gestation sac with or without a fetal pole and with or without fetal cardiac activity (depending on the gestational age) in the anterior part of the uterine isthmus; and (4) a thin (1-3 mm) or absent myometrial layer between the gestational sac and the bladder. All patients had taken Magnetic Resonance Imaging (MRI) to clarify the diagnosis . Pregnancy tissues were identified by histopathology examinations of the surgical tissues.

Exclusion Criteria:

All enrolled patients had no contraindications for transvaginal surgery or UAE, including renal failure, active pelvic infection, clotting disorders, or known allergy to the contrast material.
