Follow-up lung scans were obtained in 9 children to determine whether perfusion lung scanning could be used to verify completeness of foreign-body removal. In 4 patients, extensive perfusion defects were present 4-19 days after removal of the object. In 1 patient, the area of hypoperfusion was larger than the territory served by a persistently obstructed lobar bronchus. Follow-up lung scans are of limited value for verifying completeness of foreign-body removal and localization of retained fragments.
对9名儿童进行了后续肺部扫描，以确定灌注肺扫描是否可用于验证异物清除的完整性。4例患者在异物取出后4 - 19天出现广泛的灌注缺损。1例患者的灌注减低区域大于由持续阻塞的肺叶支气管所供应的区域。后续肺部扫描在验证异物清除的完整性和残留碎片的定位方面价值有限。
