[Cesarean scar ectopic pregnancy].

OBJECTIVE

To present our clinical experience with cases of ectopic implantation in the uterine scar of a prior cesarean section and to analyse current articles with this topic. The authors experienced two cases of cesarean scar pregnancy with different clinical management and outcome.

DESIGN

Review article, case report.

SETTING

Institute for the Care of Mother and Child, Prague, Institute for Postgraduate Medical Education, Prague.

RESULTS

We experienced two cases of cesarean scar pregnancy during the year 2006. Missed abortion in the 12th week of pregnancy was diagnosed in the first patient. During instrumental evacuation of the uterine cavity in the district hospital severe bleeding occured. After transfer to our department abdominal hysterectomy was performed. In the second case early ultrasonographic diagnosis of ectopic nidation was completed. Hysteroscopic evaluation of gestational sac with subsequent instrumental evacuation with ultrasonographic assistance was performed as a fertility saving operation. Subsequent systemic application of methotrexate was indicated after surgery.

CONCLUSION

Cesarean scar pregnancy occurs in 1/800 - 1/2216 normal pregnancies. Early sonographic diagnosis enables surgical or medicamentous treatment preserving the fertility of the patient. Late or absent diagnosis of pathological implantation can cause severe uterine bleeding. Treatment options preserving fertility can not be used and hysterectomy is then the only life saving procedure.
