In pregnancies with multiple gestation, an adverse outcome is directly proportional to the number of fetuses within the uterus, primarily because of an increased predisposition to premature delivery. Although there is a good deal of information about multifetal reduction in triplets and quadruplets and even quintuplets, there is very little on sextuplets, and virtually nothing on septuplets. Among the different techniques proposed for selective termination, two approaches have been more widely adopted: transcervical aspiration and transabdominal needling of the embryo using grey scale ultrasonography, but as yet there is no report on multifetal reduction using colour Doppler ultrasound. A method for selective termination of multiple pregnancy using transabdominal colour Doppler ultrasonography has been described here for the first time in a case of septuplets.
在多胎妊娠中，不良结局与子宫内胎儿数量成正比，主要原因是早产倾向增加。虽然有大量关于三胞胎、四胞胎甚至五胞胎减胎术的信息，但关于六胞胎的信息很少，而关于七胞胎的几乎没有。在提出的用于选择性终止妊娠的不同技术中，有两种方法被更广泛采用：经宫颈抽吸术和使用灰阶超声经腹针刺胚胎，但目前尚无使用彩色多普勒超声进行减胎术的报道。本文首次报道了在一例七胞胎病例中使用经腹彩色多普勒超声进行选择性终止多胎妊娠的方法。
