目的探讨彩色多普勒超声对小儿肠套叠的临床意义。方法对经X线空气灌肠、手术及病理证实的68例肠套叠患儿的彩色多普勒超声检查结果进行回顾性分析。结果 66例肠套叠患儿均经彩色多普勒超声检查明确诊断,诊断符合率为97.1%,误诊率2.9%,其中可探测到套入部肠管壁血流信号63例(95.45%),局部肠壁血流信号消失3例(4.54%)。4例行空气灌肠复位后复查超声发现仍有套叠声像表现,且套叠肠壁血流消失,根据超声结果行手术治疗。结论彩色多普勒超声,特别是彩色多普勒血流成像(colour Doppler flow imaging,CDFI)声像图对小儿肠套叠有重要诊断价值,且为临床选择治疗方式,及早手术避免肠管坏死发生提供可靠依据。
Objective To investigate the clinical significance of color Doppler ultrasound in children with intussusception. Methods 68 cases of intussusception confirmed by X-ray air enema, operation and pathology were retrospectively analyzed by color Doppler ultrasonography. Results 66 cases of intussusception in children were diagnosed by color Doppler ultrasonography, the diagnostic coincidence rate was 97.1%, the misdiagnosis rate was 2.9%, of which 63 cases (95.45%) of intestinal wall blood flow signals could be detected, Local intestinal wall blood flow signal disappeared in 3 cases (4.54%). 4 routine air enema re-examination ultrasound found that there are still nested ultrasound performance, and intussusception of blood flow disappears, according to the results of ultrasound surgery. Conclusions Color Doppler ultrasound, especially color Doppler flow imaging (CDFI), is an important diagnostic value in children with intussusception, and is a clinical choice of treatment, as early as possible to avoid the occurrence of intestinal necrosis Provide a reliable basis.
