According to correlative literatures, the diagnosis and treatment of bronchiolitis obliterans syndrome in three patients with hematological malignancies after allo-HSCT were analyzed. The function of haematopoiesis re-established successfully. The acute graft versus host disease did not occur in these patients except one patient occurred grade Ⅱ aGVHD, and the chronic graft versus host disease occurred in the 5th, 6th and 6th months after allo-HSCT respectively, but the cGVHD was recrudescent after treatment. The bronchiolitis obliterans syndrome occurred in the 9th, 7th and 11th months after allo-HSCT respectively, and they received the treatment of immunosuppressive, immune human serum globulin, azithromycin and to breathe in β2 receptor agonist and budesonide.

结合相关文献，对3例恶性血液病患者异基因造血干细胞移植后发生闭塞性细支气管炎综合征的临床特点和诊断治疗进行分析。3例患者移植后造血功能均顺利重建，2例未发生急性移植物抗宿主病，1例发生II度急性移植物抗宿主病；3例患者分别于移植后5，6，6个月发生广泛型慢性移植物抗宿主病，经治疗后病情仍有反复；3例患者分别于移植后9，7，11个月发生闭塞性细支气管炎综合征，给予免疫抑制剂、静脉免疫球蛋白、阿奇霉素及局部使用β2受体激动剂及布地奈德吸入治疗，2例在治疗4周后病情有所改善，另1例病情无改善。

Of 15 stenotic coronary arteries(14 occluded) with wellestablished collateral vessels, 14 displayed high signal intensities,while of the other 25 vessels (1 occluded) without any collateral vessels, only 11 had high signal intensities within the related segments.
