Objective: To analyze epidemiological characteristics and fetal/neonatal complications of twin pregnancy at the Military Hospital of Maracaibo. Methods: A descriptive and retrospective study of patients admitted with twin pregnancies, from January 1st, 1998 to May 30th, 2013. Maternal age, fetal presentations, mode of delivery, reason for interruption of the pregnancy, chorionicity, fetal/neonatal complications, weight and congenital anomalies were registered. Results: There were 31 (1.26 %) twin deliveries (or 1/80) in 2 469 pregnant woman admitted for delivery. Average maternal age was 28. The most common fetal presentation was vertex-breech in 12 (38.7 %) and in 27 (87.1 %) patients cesarean section was performed. The most common indication of pregnancy interruption were the elective delivery in 12 (38.7 %) and prematurity in 11 (35.5 %). 62 fetuses were obtained and mortality was 17.7 % with 11 stillbirth and/or perinatal death, in 8 (72.7 %) were due to monochorionicity (P< 0.05) and its consequences, of these 5 (45.46 %) were for twin-twin transfusion syndrome. Intrauterine growth restriction in 13 babies (20,9 %) and mild or severe discordant fetal growth in 26 (42 %). Congenital anomalies were observed in 8 fetuses (8.1 %) with a musculoskeletal predominance. Conclusion: Multiple pregnancy has high fetal/neonatal morbimortality which is principally dependent of the complications derived from the chorionicity, amnionicity, prematurity and the possibility of congenital anomalies. An early diagnose of the chorionicity allows the planning of antenatal care and guaranteeing the improvement of the mother and fetal/neonatal life and health.
