摘要
目的：系统评价三维超声成像技术在诊断先天性泪囊突出中的应用价值。方法：回顾性分析18例先天性泪囊突出胎儿的产前超声图像特点，并与产后结果进行对比分析。全部病例均从眼科医生或直接从患儿父母处获得随访结果。结果：胎儿先天性泪囊突出超声图像特点：二维超声扫查可见胎儿眼眶内眦部内下方类圆形，边界清晰的无回声液性区，CDFI未检出血流信号。应用三维超声成像技术同时在A（矢状切面）、B（横切面）、C（冠状面）平面显示该液性区，多层面分析病灶与周围组织的毗邻关系，利用三维表面成像技术可直观显示内眦部向表面突出的包块。产前共18例胎儿怀疑为先天性泪囊突出，产后均得到证实。囊肿直径在0.3~1.2 cm之间，均无眼球受压移位现象。结论：三维超声成像技术可对先天性泪囊突出病灶处做出全面的评估，包括病变位置，病灶各个径线的大小，血运情况，与周围软组织及骨性结构的毗邻关系等。本研究发现先天性泪囊突出病灶最长径线大于或等于1.0 cm，且多次复查未见明显减小者，自愈率低，预后相对较差。三维超声成像技术在诊断胎儿先天性泪囊突出中有重要的临床应用价值。
Abstract
Objective: To assess the application value of three-dimensional ultrasonography in the diagnosis of congenital dacryocystocele. Methods: Ultrasonic findings of 18 fetuses with congenital dacryocystocele were retrospectively analyzed and compared with the findings after induction. All of the patients’ follow-up results were obtained from the Ophthalmology doctor or directly from the parents of children. Results: Congenital dacryocystocele ultrasonic image features: 2D ultrasound scanning showed well-defined anechoic fluid zone over the medial infraorbital area with no blood flow signal on CDFI. Three-dimensional ultrasonography could analyse the relationship between the lesions and surrounding tissues through multilayer surface by displaying the liquid zone through A-plane(sagittal section), B-plane(transverse section), C-plane(coronal section) at the same time. The bulging mass from the surface over the medial infraorbital area could be directly displayed by using three-dimensional surface imaging technology. The 18 fetuses were all diagnosed and confirmed with congenital dacryocystocele after birth. The cysts’ diameters were between 0.3~1.2 cm. There were no signs of eyeball compression or displacement. Conclusion: Three-dimensional ultrasonography can make comprehensive evaluation of congenital dacryocystocele, including the location, size, hemodynamic conditions, and relations with surrounding soft tissue and bony structures. When the longest diameter of congenital dacryocystocele was not less than 1.0 cm with no reduction by follow-up, low self-healing rate and poor prognosis would occur. Three-dimensional ultrasonography has great clinical value in diagnosis of congenital dacryocystocele.
