Small sac size in the first trimester: a predictor of poor fetal outcome

Article Abstract:

Up to 25 percent of clinically recognized pregnancies end in a spontaneous (natural) abortion. Once a fetal heartbeat is detected, the risk of spontaneous abortion decreases dramatically, occurring in only 2 to 4 percent of pregnancies. It is not clear whether there are indicators of a possible spontaneous abortion once the heartbeat has been established. Some evidence exists that a small embryonic sac size during the first trimester of pregnancy, even when the fetal heartbeat is present, indicates a higher risk of spontaneous abortion. This study followed 17 pregnancies in which a fetal heartbeat was present but so was a small sac during the first trimester. A group of 52 pregnancies where sac size was normal was also followed for purposes of control. A small sac size was determined to be a difference between mean sac size (MSS) and crown-rump lengths (CR) of less than 5 mm. Results found that in the small sac group, spontaneous abortion occurred in 15 of the 16 pregnancies (94 percent) compared with 4 of 52 (8 percent) in the control group. These results indicate that once a fetal heartbeat has been established, a small sac size during the first trimester is a good indicator of a probable poor outcome of the pregnancy.
