核素淋巴显像诊断乳糜胸腹水

目的 :评估核素淋巴显像定性及定位诊断乳糜胸腹水的价值。材料和方法 :回顾性总结 5 7名拟诊为乳糜胸腹水患者共 79例次的淋巴显像 ,分析图像特点 ,并与其他影像学检查手段进行比较。结果 :5 7例患者的首次显像中 32例为阳性 ,2 1例基本可以确定漏出部位 ,7例随访患者的多次显像结果与临床表现及其他影像学检查基本一致。该方法定性诊断的灵敏度为 82 % ,特异性为 10 0 % ,准确性为 88%。结论 :淋巴显像对乳糜胸腹水的定性及定位有重要作用 ,并能为病因诊断提供线索 ,同时也是评估治疗效果的可靠方法

Clinical Application of Lymphoscintigraphy in Chylothorax and Chyloperitoneum

Purpose: To evaluate the clinical efficacy of lymphoscintigraphy in chylothorax and chyloperitoneum. Materials and Methods: 79 lymphoscintigrams in 57 cases suspected of chylothorax or chyloperitoneum were analyzed retrospectively. Results: 32 cases were found positive sintigraphically and the sites of leakage could be identified in 21 cases. Multiple followup scans in 7 cases corresponded closely to the clinical manifestation and other imaging findings. The sensitivity, specificity and accuracy of the modality in diagnosis is 82%, 100% and 88% respectively. Conclusion: lymphoscintigraphy plays an important role in confirming and localizing chylothorax or chyloperitoneum, and is helpful in etiological diagnosis. It is also the best modality to evaluate therapeutic effect.
