【摘要】：目的:觀察和探討產(chǎn)前進(jìn)行超聲診斷胎兒四肢骨骼系統(tǒng)發(fā)生畸形的情況,針對(duì)不同孕期檢出率進(jìn)行比較分析,以期為臨床診斷和預(yù)測胎兒肢體骨骼畸形提供客觀的理論依據(jù)。方法:入選于我院進(jìn)行產(chǎn)前超聲篩查的孕婦2380例作為研究觀察對(duì)象,對(duì)產(chǎn)前超聲診斷為肢體骨骼畸形的胎兒進(jìn)行引產(chǎn)后經(jīng)放射線診斷和尸檢結(jié)果證實(shí)均存在肢體骨骼畸形,分析產(chǎn)前超聲檢查對(duì)胎兒肢體骨骼畸形檢出情況,并針對(duì)不同孕期的診斷準(zhǔn)確性進(jìn)行對(duì)比分析。結(jié)果:經(jīng)篩查結(jié)果顯示,2380例胎兒經(jīng)孕婦產(chǎn)前常規(guī)超聲檢查出現(xiàn)肢體骨骼畸形28例,肢體骨骼畸形發(fā)生率為1.18%。對(duì)不同類型胎兒肢體骨骼畸形進(jìn)行超聲篩查結(jié)果顯示,經(jīng)引產(chǎn)或尸檢證實(shí)例數(shù)為45例,其中產(chǎn)前超聲診斷符合率為62.2%,產(chǎn)后證實(shí)率為37.8%;針對(duì)不同孕周胎兒肢體骨骼畸形超聲篩查結(jié)果進(jìn)行統(tǒng)計(jì)分析結(jié)果顯示,孕18~24周檢出率高達(dá)93.75%,孕25~32周檢出率高達(dá)93.33%,其檢出率明顯高于孕11~17周(37.5%)及孕期33周(50%),差異具有顯著性(P0.05)。結(jié)論:產(chǎn)前超聲檢查診斷胎兒肢體骨骼系統(tǒng)發(fā)育畸形準(zhǔn)確率較高,同時(shí)具有無創(chuàng)性、可重復(fù)性、安全性等優(yōu)勢,特別是中孕期進(jìn)行超聲診斷大大提高了畸形的檢出率,因此在中孕期進(jìn)行超聲診斷是產(chǎn)前診斷胎兒肢體骨骼畸形的有效手段。
[Abstract]:Objective: to observe and discuss the ultrasonic diagnosis of fetal limb skeletal system malformation in prenatal, and to compare and analyze the detection rate of fetal limb skeletal system in different pregnancy, in order to provide objective theoretical basis for clinical diagnosis and prediction of fetal limb bone malformation. Methods: 2380 pregnant women who were screened by prenatal ultrasound in our hospital were selected as the observation objects. The fetus diagnosed by prenatal ultrasound was proved to have limb bone malformation by radiography and autopsy after induced labor. To analyze the detection of fetal limb deformities by prenatal ultrasound, and to compare the diagnostic accuracy of different pregnancies. Results: the results of screening showed that 28 cases of limb bone malformation were detected by prenatal routine ultrasound in 2380 fetuses, and the incidence of limb bone malformation was 1.18%. The results of ultrasonic screening of different types of fetal limb bone deformity showed that 45 cases were confirmed by induced labor or autopsy. The coincidence rate of prenatal ultrasound diagnosis and postpartum diagnosis was 62.2% and 37.8% respectively. According to the results of ultrasonic screening of fetal limb bone deformity in different gestational weeks, the results showed that the detection rate of fetal limb bone deformity in 1824 weeks and 2532 weeks of pregnancy was as high as 93.75 and 93.33 respectively. The detection rate was significantly higher than that of 1117 weeks (37.5%) and 33 weeks (50%) of pregnancy (P0.05). Conclusion: the accuracy of prenatal ultrasound in diagnosing fetal limb skeletal system deformity is high, and it has the advantages of noninvasive, repeatability and safety. Especially, ultrasound diagnosis during pregnancy can greatly improve the detection rate of deformities. Therefore, ultrasound diagnosis during pregnancy is an effective method for prenatal diagnosis of fetal limb deformities.
