ABSTRACT

OBJECTIVES:

The purpose of this study is to investigate the clinical risk factors of emergency cesarean hysterectomy in patients with pregnancies complicated by placenta previa and whether the third trimester transvaginal ultrasonographic findings of placenta previa would predict emergency cesarean hysterectomy. MATERIALS AND

METHODS:

Between January 1995 and March 2005, we retrospectively reviewed the records and compared between patients with pregnancies complicated by placenta previa who underwent cesarean hysterectomy and patients with pregnancies complicated by placenta previa who did not undergo cesarean hysterectomy.

RESULTS:

There were 314 had placenta previa and 34 patients were performed cesarean hysterectomy (10.83%). There were significant differences on the basis of maternal age (31.53+/-4.41 vs 34.06+/-4.12, p<0.05), parity (0.81+/-0.70 vs 1.29+/-0.63, p<0.05) , the number of cesarean section (0.36+/-0.56 vs 0.91+/-0.75, p<0.05), previous history of placenta previa and presence of placenta accreta, but not on the basis of gestational age, the number of antenatal vaginal bleeding, the number of abortions and emergency operation between two groups. On the basis of third trimester transvaginal ultrasonographic findings, significant differences were found on the distances from the internal os of cervix (1.18+/-3.66 vs 2.67+/-2.94, p<0.05) and thickness of lower placental edge. However, the presence of lacuna in the lower placenta was not associated with emergency hysterectomy.

CONCLUSIONS:

Patients with placenta previa are at a higher risk of undergoing cesarean hysterectomy when they are associated with placenta accreta, thick lower placenta edge, and positively longer distance to the internal os of cervix. The other clinical factors such as maternal age, parity, the number of cesarean section and previous history of placenta previa might be associated the risk of cesarean hysterectomy.
