高频超声在儿童腹型过敏性紫癜中的应用

Application of high frequency ultrasound in children with Henoch-Schonlein purpura

目的探讨高频超声检查在儿童腹型过敏性紫癜中的应用价值。方法选取76例经临床确诊为腹型过敏性紫癜的患儿,回顾性分析其治疗前腹部超声特征。结果 76例患儿中有64例在治疗前出现不同程度肠壁增厚,增厚肠壁血流较周围正常肠壁增多且伴肠蠕动异常,病变均位于小肠,部分合并肠系膜淋巴结肿大及盆腹腔积液。腹型过敏性紫癜合并消化道出血患者肠壁增厚比例明显高于无合并消化道出血的患者。结论腹型过敏性紫癜声像图改变具有一定特异性,有助于该病的早期诊断及疗效观察,超声可作为常规首选检查方法。

Objective To explore the value of high frequency ultrasound in the diagnosis of abdominal type Henoch-Schonlein purpura（HSP） in children.Methods A retrospective analysis was carried out on abdominal ultrasound characteristics of 76 children who were clinically diagnosed with abdominal type HSP. Results Of 76 cases, 64 cases showed bowel wall thickening in different degrees before treatment, blood flow in the thickening intestinal wall was more than surrounding normal intestinal wall, and accompanied by abnormal peristalsis.Lesions were located in small intestine, and partly with mesenteric lymph nodes enlargement arid pelvic and peritoneal effusion. The proportion of intestinal wall thickening in patients with abdominal type HSP complicated with gastrointestinal bleeding was significantly higher than that in patients without gastrointestinal bleeding.Conclusion The uhrasonogram changes of abdominal type HSP are specific, which is helpful for the early diagnosis and curative effect observation of the disease, and ultrasound can be used as the first choice of routine examination.
