ABSTRACT
Objective To clarify the risk,treatment and preventive measurement of transfusion related acute lung injury (TRALI) occurred in HLA half-matched hematopoietic stem cell transplantation. Methods A case of TRALI occurred in HLA half-matched hematopoietic stem cell transplantation was analyzed,including the clinical characteristics,the laboratory and instrumental examination,the treatment measure and prognosis,and then the associated literature was reviewed.Results Owing to the blood products(fresh platelet) transfusion during transplantation,the patient got TRALI. And after active rescue,the patient eventually died due to the worsen condition.Conclusion The risk of TRALI is very high in HLA half-matched hematopoietic stem cell transplantation since the blood products transfusion is inevitable,so the effective and timely treatment and preventive measurement are necessary.
