高频超声诊断小儿急性肠系膜淋巴结炎的临床价值

High Clinical Value of Ultrasonography in the Diagnosis of Acute Mesenteric Lymphadenitis in Children

目的评价高频超声诊断小儿急性肠系膜淋巴结炎的临床价值;方法选择2014年1月—2015年12月在该院接受高频超声检查的CAML患儿66例,以高频超声诊断,测量淋巴结的长径、短径,并计算纵横比(长径/短径),仔细察看肿大淋巴结多普勒血流表现。治疗一周后复查。结果脐周肿大淋巴结患儿21例(31.82%),右上腹部肿大淋巴结40例(60.61%),左上腹部肿大淋巴结5例(7.58%)。淋巴结多呈簇状分布,未见融合。边缘光滑,呈肾形或椭圆形,皮质髓质界限清晰。长径为(1.48±0.37)cm,短径为(0.72±0.17)cm,纵横比均>2。肿大淋巴结内均可探及分支状或点状彩色血流。一周后复查,所有患儿淋巴结数量均减少,体积缩小或消失,多普勒彩色血流难以探及。结论小儿CAML具有明确的高频超声特征,以高频超声诊断小儿CAML准确率高,具有较高临床应用价值。

Objective Evaluation of high frequency ultrasonography in the diagnosis of acute mesenteric lymphadenitis in children clinical value; Methods From January 2014 to December 2015 examined by high frequency ultrasound in our CAML 66 cases of children, using high-frequency ultrasound in diagnosis and measurement, short of length and diameter of lymph node size and calculate the aspect ratio(lengthdiameter/short diameter) and examined lymph Doppler blood flow.Treatment a week later. Results Umbilicus in children with enlarged lymph nodes in 21 cases(31.82%),right of swollen lymph nodes in abdomen in 40 cases(60.61%), upper left abdominal adenopathy in 5 cases(7.58%).Clusters of lymph nodes are distributed, no fusion.Smooth edges, are kidney-shaped or oval, cortex and Medulla boundaries clear.Length to diameter(1.48±0.37) cm, shorter sizes(0.72±0.17) cm, The aspect ratio>2, and branch-like or point-like color flow.A week later, all number of lymph node in patients with decreased volume or disappear, Doppler color flow to, and; Conclusion CAML has clear characteristics of high frequency ultrasound in children, using high-frequency ultrasound in diagnosis of children with CAML high accuracy with high clinical value.
