高频超声对小儿肠系膜淋巴结炎的诊断价值

Diagnostic value of mesenteric lymphadenitis in childrn by high-freguency ultrasound

目的：探讨小儿肠系膜淋巴结炎的超声表现及诊断价值.方法：对150例反复腹痛,部分伴呕吐、发热、腹泻,经儿科医师诊断为肠系膜淋巴炎的患儿行高频超声检查.详细记录淋巴结回声以及出现部位、数目、大小,并用彩色多普勒观察淋巴结内部血流状况.结果：150例患儿腹腔内均可探及3枚以上淋巴回声,呈多个或簇状分布,纵径：1.0~2.7、横径：0.5~1.3,纵横比≥2.0.CDFI：肿大淋巴结内血流信号分布呈淋巴门型或无血流型,为低速低阻型,RI：＜0.7,经对症及抗炎治疗后复查,肿大淋巴结较前不同程度缩小或消失.结论：高频超声作为一种经济、无创、可重复的检查方法是小儿肠系膜淋巴结炎首选的诊断方法.

Objective To explore mesenteric lymphadenitis in children and diagnostic value of ahrasonography. Method 150 cases of recurrent abdominal pain, accompanied by vomiting, fever, diarrhea, were diagnosed of mesenteric lymphadenitis by high-frequency ultra- sound. Detailed records of lymph nodes,number, size, echo and parts with color doppler blood flow to look inside the lymph node sta- tus. Results 150 cases of children with abdominal cavity were available,and three or mole lymph echo,mnhiple or clusters of distributed, longitudinal diameter ： 1.0 - 2.7,transverse diameter ：0. 5 - 1.3, aspect ratio 2. 0 or higher of a CDIq ： enlarged lymph nodes in the distribu- tion of blood flow sign.,d was lymphatic door or no blood flew, type of low speed and low resistance, llI 〈 0. 7. By symptomatic and review af- ter anti - irfflammatory treatment ,swelling lymph nodes had different degrees of reduction or disappearance. Conclusion ttigh frequency ul- trasound, as a kind of economic,non -invasive and repeatable examination method is the preferred diagnostic method for pediatric mesenter- ic !ymphadenitis.
