The objective of this study is to investigate the clinical characteristics of placental adhesions in order to improve maternal and fetal well-beings. METHODS: We reviewed the medical records of twenty cases of placental adhesions from January 1, 1995 to December 31, 1999 in Dankook University Medical Center. RESULTS: The incidence of placental adhesions is 0.267%. Of them, the percentage of placenta accreta was 35%, placenta increta, 60% and placenta percreta, 5%. Placental adhesions were observed more often in multipara (80%) than nullipara (20%). Co-existing placenta previa (50%), previous cesarean delivery (40%), multigravidity (5 or more; 40%) and previous artificial abortion (70%) were associated with placental adhesions. 85% of placental adhesions were treated by hysterectomy in order to manage postpartal uterine bleeding. Packed red cell transfusions were necessary in 18 cases of placental adhesions (90%). Maternal complications were wound infection (10%), disseminated intravascular coagulation, throm- boembolism, stress ulcer, postoperative fever, bladder perforation, pulmonary edema, and pleural effusion etc. Fetal complications were preterm birth (30%), neonatal death (5%), and fetal death in utero (10%). CONCLUSION: This study revealed that placental adhesions show grave maternal and fetal complications. Obstetricians should examine carefully to confirm placental adhesions and prepare thoroughly the postpartal emergency-care, especially in the high-risk gravida.
