OBJECTIVE: To investigate the possible role of multifetal pregnancy reduction as a risk factor for the development of periventricular leukomalacia, which has been associated with prematurity and twin pregnancies.
DESIGN: A case-control study.
SETTING: In Vitro Fertilization Unit and Intensive Care Nursery of the Tel Aviv Sourasky Medical Center, Tel Aviv, Israel.
PATIENT(S): A total of 1,401 consecutive preterm infants who were born between January 1, 1994, and December 31, 1995.
INTERVENTION(S): Cranial ultrasonographic evaluation of each infant within 3 days of birth.
MAIN OUTCOME MEASURE(S): Premature infants who developed periventricular leukomalacia (cases) were compared with premature infants who did not develop this disorder (controls) when multifetal pregnancy reduction was considered.
RESULT(S): Fourteen premature infants developed periventricular leukomalacia. Of these, 28.6% (4 infants) were exposed to multifetal pregnancy reduction, compared with 1.9% of the controls, giving an odds ratio (OR) of 20.9 (95% confidence interval [CI] 5.5-79.4). Adjustment of this OR for IVF treatment (OR, 18.6; 95% CI, 1.8-140.3), twinning (OR, 6.3; 95% CI, 1.3-30.3), and for both IVF treatment and twinning simultaneously (OR, 8.5; 95% CI, 1.7-42.2) did not explain all the observed associations between periventricular leukomalacia and multifetal pregnancy reduction.
CONCLUSION(S): Our data suggest that multifetal pregnancy reduction may be an additional risk factor for periventricular leukomalacia among premature infants, regardless of twinning.
