RESUMO
OBJECTIVE: To evaluate outcome of trial of labor after cesarean section (TOLAC) with fetal weight >3500 g. MATERIALS AND METHODS: This retrospective descriptive study was carried out between March 1, 2012, and February 28, 2015. Medical and obstetrical records of women with birth weight (BW) >3500 g admitted in the labor ward with advanced labor or admitted in early labor but with underestimated fetal weight >3500 g were analyzed. Main variables analyzed included maternal parity, vaginal delivery prior to TOLAC, the BW and the integrity of the uterine scar. RESULTS: Mean BW was 3789.3 g. Out of 36 women, 75 % had a successful TOLAC. Women who delivered vaginally before TOLAC had a higher success rate than women who never delivered vaginally (94.1 vs. 63.1 %, P < 0.044). CONCLUSION: Successful TOLAC with birth weight >3500 g can be observed among women, especially among those admitted in advanced labor or with successful vaginal delivery prior to the current TOLAC.
