Abstract:
OBJECTIVE: To investigate the clinical characteristics and etiologic factors of pregnancies with fetal death in utero (FDIU). METHODS: Retrospective review of medical records of 184 pregnancies with FDIU between March 1996 and March 2006 was conducted and descriptive analysis was done. Medical records were unavailable in 14 cases which were excluded in the analysis of etiology and diagnostic evaluation. RESULTS: The overall incidence was 1.31%. There was no significant difference in the yearly incidence during the study period. Age distribution of FDIU was between 18 and 44 and the incidence was highest in 25~29 year-old age group. The risk analysis showed statistically significant risk in the age group under 25 (OR, 2.455) and 25~29 (OR, 1.590) compared to 30~34 year-old age group. The risk of age group beyond 35 has a tendency to increase but was not statistically significant. FDIU was the most prevalent (38.58%) among pregnancies less than 29 weeks of gestation. Most of cases were delivered vaginally (86.5%). Etiologic factors included unexplained causes (37.1%), fetal factors (29.4%), placental and cord factors (18.2%) and maternal factors (15.3%). Autopsy was done in 128 cases (75.3%) and placental pathology was examined in 148 cases (87.1%). Among the workups done, autopsy and placental pathology were the most informative. CONCLUSION: Despite the advance of prenatal care, the incidence of FDIU was steady throughout the study period. The etiology of the largest proportion was unexplained. Once FDIU is diagnosed, prompt delivery should be done and appropriate diagnostic tests should be offered to aid in next pregnancy.
