【摘要】：目的總結(jié)不對(duì)稱性聯(lián)體雙胎產(chǎn)前超聲表現(xiàn)并與產(chǎn)后病理尸檢結(jié)果對(duì)照分析。方法對(duì)2003年1月至2016年1月湖北省婦幼保健院產(chǎn)前超聲及病理尸檢確診的4例不對(duì)稱性聯(lián)體雙胎超聲聲像圖及尸檢結(jié)果進(jìn)行對(duì)照研究。結(jié)果產(chǎn)前超聲顯示4例不對(duì)稱性聯(lián)體雙胎中3例寄生胎均可顯示雙小上肢,其中2例可顯示從主胎胸腹部延伸出的雙小下肢及臀部,未見(jiàn)肢體自主活動(dòng);產(chǎn)前超聲漏診1例寄生胎(未檢出寄生胎的小肢體而漏診)。4例不對(duì)稱性聯(lián)體雙胎中2例主胎合并臍膨出,3例心臟畸形和脊柱畸形,2例膀胱外翻,2例顏面部畸形,3例羊水多。與引產(chǎn)胎兒檢查結(jié)果對(duì)照顯示,4例產(chǎn)前超聲診斷主胎合并畸形均與引產(chǎn)后X線及尸檢結(jié)果相符合,4例寄生胎均有小的臀部、雙小上肢及雙小下肢。引產(chǎn)胎兒標(biāo)本X線攝片均可清晰顯示寄生胎肢體及骨骼多發(fā)畸形、產(chǎn)前超聲僅漏診1例寄生胎。結(jié)論不對(duì)稱性聯(lián)體雙胎常合并全身多發(fā)畸形,產(chǎn)前超聲發(fā)現(xiàn)寄生胎及其多余的肢體是診斷不對(duì)稱性聯(lián)體雙胎的重要線索。超聲與X線檢查及胎兒尸檢是發(fā)現(xiàn)不對(duì)稱性聯(lián)體雙胎所有畸形并最終確診的重要檢查方法。
[Abstract]:Objective to summarize the antepartum ultrasonographic findings of asymmetrical conjoined twins and to compare the results with postpartum pathological autopsy. Methods from January 2003 to January 2016, the diagnosis of prenatal ultrasound and pathological autopsy in Hubei Maternal and Child Health Hospital was confirmed. Four cases of asymmetrical conjoined twins were studied by ultrasonography and autopsy. Results 3 of 4 cases of asymmetrical conjoined twins were detected by prenatal sonography, and 3 cases of parasitic fetuses showed double small upper limbs. In 2 cases, both small lower limbs and buttocks extending from the chest and ventral part of the main fetus were shown, and no spontaneous movement of the limbs was observed. Antepartum ultrasound missed the diagnosis of one parasitic fetus (no limb of the parasitic fetus and missed diagnosis of 4 cases of asymmetrical conjoined twins) 2 cases of main fetus with umbilical exophthalmos 3 cases of cardiac malformation and 2 cases of spinal deformity of bladder valgus. There were 3 cases of amniotic fluid in 2 cases of facial malformation and 3 cases of amniotic fluid. The results of fetal examination showed that 4 cases of main fetus complicated with malformation diagnosed by prenatal ultrasound were consistent with the results of X ray and autopsy after induced labor in 4 cases of parasitic fetus with small buttocks. Both small upper limbs and both small lower extremities. X ray films of fetal specimens of induced labor can clearly show multiple deformities of parasitic fetal limbs and bones. Only one parasitic fetus was missed by prenatal ultrasound. Conclusion asymmetrical conjoined twins are often associated with multiple malformations throughout the body. Prenatal ultrasound detection of parasitic twins and their excess limbs is an important clue for the diagnosis of asymmetrical conjoined twins. Ultrasound and X-ray examination and fetal autopsy are important examinations for the detection of all malformations and final diagnosis of asymmetrical conjoined twins. Methods.

【正文快照】： 聯(lián)體雙胎是一種罕見(jiàn)的先天畸形,是由于胚盤在受精13 d后發(fā)生的分離不全所致[1]。近年國(guó)內(nèi)報(bào)道的聯(lián)體雙胎發(fā)生率為0.001%~0.002%[2],國(guó)外報(bào)道發(fā)生率為0.0019%[3]。聯(lián)體雙胎畸形分為對(duì)稱性和不對(duì)稱性兩大類[4],對(duì)稱性聯(lián)體雙胎是指兩個(gè)發(fā)育接近正常的胎兒胸腹等部分相連,不對(duì)稱性，
