[Effects of subchorionic hematoma on pregnancy outcome: a meta analysis]
1Obstetrics and Gynecology Hospital, Fudan University, Shanghai 200090, China.
Objective:
To study the effects of subchorionic hematoma (SCH) on pregnancy outcome.
Methods:
We searched publications from January 2000 to July 2015 for cohort and case-control studies evaluating subchorionic hematoma and perinatal outcomes, including spontaneous abortion, premature delivery and delivery mode.
Results:
Data of 6 articles analyzed by meta-analysis showed that SCH group had higher rate of spontaneous abortion, while no difference in premature delivery and delivery mode, compared with threatened abortion group.
Conclusion:
Subchorionic hematoma increases the risk of spontaneous abortion, while premature delivery rate and delivery mode are not affected if the pregnant women can continue the pregnancy.
