胎儿血管瘤与浅表血管瘤的超声影像研究

Ultrasonographic study of fetal hemangioma and superficial hemangioma

目的:研究不同病理分型浅表血管瘤的超声影像特点和胎儿血管瘤的超声影像及预后转归。方法:回顾性分析3例胎儿血管瘤的影像特点并追踪其预后转归;对17例浅表血管瘤分析其影像特点,并根据病理结果分组进行对照研究。结果:3例胎儿血管瘤,1例为2个病灶、2例为单发,回声为低回声或等回声,血流较丰富,血供以动脉为主,未合并其他畸形及心衰,随诊至生后病灶未见消退。17例浅表血管瘤中,病理结果以海绵状血管瘤与毛细血管瘤多见,两组对照,病灶回声、血流的差异有统计学意义(P <0.05);病灶大小、边界、形态的差异无统计学意义(P> 0.05)。结论:超声可较准确诊断血管瘤及其病理分型,对于胎儿血管瘤超声可评估病变,随访转归,对临床干预措施的选择有重要的指导作用。

Objective To study the imaging features of superficial hemangioma with different pathological types and the ultrasonographic features and prognosis of fetal hemangioma.Methods The imaging features and prognosis of 3 cases of fetal hemangioma were analyzed.The imaging features of 17 cases of superficial hemangioma were analyzed retrospectively.Comparative study based on pathological results in groups.Results In 3 cases of fetal hemangioma,1 case was two lesions,2 cases were single,echo was hypoechoic or isoechoic,blood flow was abundant,blood supply was mainly artery,no other malformation and heart failure were complicated.In 17 cases of superficial hemangioma,cavernous hemangioma and capillary hemangioma were more common than those in control group.There was significant difference in echo and blood flow between the two groups(P<0.05).There was no significant difference in the size,border and shape of the lesion(P﹥0.05).Conclusion Ultrasound can accurately diagnose hemangioma and its pathological classification,and can be used to evaluate Characteristics of lesions in fetal hemangioma and follow up the outcome of the lesions.It has an important guiding role on the choice of clinical intervention measures.
