【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 evaluate the value of three-dimensional ultrasonography in the diagnosis of congenital lacrimal sac herniation.Methods: the ultrasonographic features of 18 cases of congenital lacrimal sac protruding fetus were analyzed retrospectively and compared with postpartum results.All cases were followed up from ophthalmologists or directly from parents.Results: the characteristics of fetal congenital lacrimal sac protruding ultrasound image: 2D ultrasound scan showed that the fetal orbital medial canthus was round below the medial canthus and the boundary was clear. CDFI did not detect the bleeding flow signal.Three-dimensional ultrasound imaging was used to display the fluid region on the A (sagittal section) C (coronal) plane simultaneously. The adjacent relationship between the lesion and the surrounding tissue was analyzed on multiple layers.By using three-dimensional surface imaging technique, the medial canthus projecting mass can be visualized.A total of 18 fetuses suspected congenital lacrimal sac protrusion were confirmed postpartum.The diameter of cyst was between 0.3 and 1.2 cm, and there was no displacement of eyeball compression.Conclusion: Three-dimensional ultrasound imaging can be used to evaluate the location of congenital lacrimal sac protruding lesions, including the location of lesions, the size of each diameter of the lesions, the blood flow, the adjacent relationship with the surrounding soft tissue and bone structure, etc.In this study, we found that the longest diameter of congenital lacrimal sac protrusion was greater than or equal to 1.0 cm, and the self-healing rate was low and the prognosis was relatively poor.Three-dimensional ultrasound imaging has important clinical value in the diagnosis of congenital lacrimal sac herniation.
