In the clinical settings, disseminated intravascular coagulation (DIC) and complications such as hemorrhage are commonly seen in acute promyelocytic leukemia patients, whereas thrombosis is rarely reported. We reported a case here that the patient presented with cerebral infarction as the first manifestation. During the admission, the patient encountered differentiation syndrome, pulmonary embolism, pulmonary hemorrhage, and myocardial ischemia, as well as bleeding and thrombosis complications. Hence the patient was diagnosed as DIC. After the treatment of blood transfusion instead of anticoagulation, his condition was stable and the remission was completely achieved. The treatment experience provides guides for other patients with similar complications of simultaneous bleeding and thrombosis.
急性早幼粒细胞白血病常见出血等并发症，而栓塞并发症较少报道。本例患者以脑梗死表现起病，治疗过程中出现分化综合征、肺动脉栓塞合并肺出血和心肌缺血的表现，即同时存在出血和栓塞并发症，诊断为弥散性血管内凝血。经过成分输血等治疗，患者顺利完成诱导缓解治疗。该患者的治疗经验可为出血合并栓塞并发症的患者提供帮助。.
