目的:总结胎儿鳃裂囊肿的产前超声表现,结合预后探讨产前超声诊断价值。方法:回顾性分析35例鳃裂囊肿胎儿的临床资料,所有胎儿均随访至引产或分娩后手术。结果:35例患儿产前正确诊断29例,误诊2例,漏诊4例。声像表现为颈部软组织深面薄壁囊性无回声,2例见细分隔,均未见血流信号显示。囊肿大小和孕周无相关性,囊肿最大直径约24.1~53.9 mm,平均(37.7±9.3)mm。分娩后需外科手术治疗,手术难度较大。结论:鳃裂囊肿呈特征性颈部一侧囊性无回声。产前超声能明确囊肿与周围血管、组织之间的关系,并可与其他颈部肿块相鉴别,可作为有效的产前检查手段,指导临床决策。
OBJECTIVE: To summarize the prenatal ultrasound manifestations of fetal branchial cleft cyst and explore the value of prenatal ultrasound in combination with prognosis. Methods: The clinical data of 35 cases of branchial gland cyst rupture were retrospectively analyzed. All the fetuses were followed up until the abortion or postpartum operation. Results: 35 cases of prenatal correct diagnosis of 29 cases, misdiagnosis in 2 cases, missed diagnosis in 4 cases. The acoustic findings were deep thin cystic aneurysm in the soft tissue of the neck, and in 2 cases, fine separation was found. No blood flow signal was found. There was no correlation between cyst size and gestational age. The maximum diameter of cysts was about 24.1-53.9 mm, with an average of (37.7 ± 9.3) mm. Surgical treatment after childbirth, surgery more difficult. Conclusion: The branchial cyst is characteristic cystic anechoic on one side of the neck. Prenatal ultrasound can be clear cysts and the surrounding blood vessels, the relationship between the organization, and other neck mass can be differentiated, can be used as an effective prenatal examination to guide clinical decision-making.
