“…Since there is no evidence that twins have a lesser intrinsic growth potential than singletons, their smaller average size must be attributed to an environmental effect. This is substantiated by both birth weight (McKeown and Record, 1952;Naeye et a/, 1966;Bleker et al, 1979) and ultrasound (Bleker et al, 1977) studies. Consequently, when assessing perinatal risks, singleton standards may be used to definite abnormalities of fetal size, growth and birth weight in twins, as has been done in the studies described here.…”

Summary As methods for identifying the small‐for‐dates fetus in twin pregnancies, serial ultrasonic cephalometry and a new two‐stage ultrasound examination schedule have been evaluated and compared. Serial cephalometry is associated with technical and interpretative problems, and only 24 (56 per cent) of 43 small‐for‐dates fetuses in 66 retrospectively studied twin pregnancies showed detectably abnormal biparietal diameter growth. The two‐stage schedule comprises an accurate assessment of gestational age in early pregnancy, and determination of the product of the crown‐rump length and trunk area at 34 to 36 weeks; this identified all 15 small‐for‐dates fetuses in 21 prospectively studied twin pregnancies, and the method offers several other advantages over serial cephalometry.

“…Meanwhile, as nulliparity increased, instance of PIH increased and that of SGA delivery decreased in twins. Considering a contradictory view by Blecker et al ., 15 we hypothesized that relatively high immune adaptation in multiparous women may limit BP elevation to suboptimal levels. Shared interplacental blood flow is not sufficient to nourish both fetuses to an AGA size due to low uteroplacental perfusion.…”

“…Analisando-se a literatura pertinente, detecta-se erros cometidos na obtenção de algumas curvas de crescimento dos parâmetros biométricos ultrasonográficos para gestações gemelares. As principais são a omissão de critérios de inclusão e exclusão da população analisada por alguns autores 17,18,19,20,21,22,23 ou a inclusão de gestações gemelares com patologias fetomaternas 24,25,26,27 , fatos que podem comprometer o resultado dos trabalhos.…”

“…A maioria dos estudos constata valores menores do diâmetro biparietal médio nos fetos gêmeos comparados aos únicos durante o terceiro trimestre 1,16,18,22,25,26,30,31 . Outros verificam que o diâmetro biparietal médio de gêmeos é menor durante todo o período gestacional em relação a fetos únicos 19,20,32 , enquanto alguns 2,21,23,24 não encontram diferenças significativas.…”
