EXTRACTION OF FETAL HEART ACTIVITY BY USING BISPECTRUM-BASED ELECTROMYOGRAPHY SIGNAL PROCESSING

Background : Cesarean scar pregnancy (CSP) is the implantation of the gestational sac in the hysterotomy scar. The optimal treatment for a cesarean scar pregnancy is unclear and therapy should be selected according to the patients' clinical presentation. The aim of this study was reporting a successful medical treatment of a cesarean scar pregnancy with fetal heart activity and a very high level of beta human chorionic gonadotropin (β-hCG). Case Presentation: A 38-year-old woman referred for routine prenatal visit after 2 months of menstrual retard and positive pregnancy test. She had the history of 3 cesarean sections and a uterine curettage. Untrasonography revealed cesarean scar ectopic pregnancy. The serum level of β-hCG was 109063 mIU/ml. Two doses of systemic methotrexate therapy and intragestational sac injection of methotrexate and potassium chloride were administered. 8 weeks after the initial treatment, β-hCG level became undetectable. Conclusion: Combined medical treatment with local and systemic MTX administration may be a successful treatment with low complication even in the presence of high serum β-hCG level.

Cesarean scar ectopic pregnancy (CSP) is a rare type of ectopic pregnancy that is growing in incidence. The diagnosis of most CSP occurs when patients present in unstable conditions requiring surgical management and leading sometimes to hysterectomy. It has been shown that medical management is a safe option for early diagnosed hemodynamically stable CSP. However, no cases of CSP withβ-hCG higher than 62,000 IU/L, conservatively treated, have been reported. We report the case of a 29-year-old patient who presented for her first prenatal visit at 13-week gestation and was diagnosed with CSP with present fetal heart tones and a quantitativeβ-hCG of 144,337 IU/L. She was treated with bilateral uterine artery embolization and systemic methotrexate. Herβ-hCG significantly decreased and became undetectable within 10 weeks. We propose that patients with CSP with very highβ-hCG and fetal heart activity can be offered conservative or fertility preserving management.
