Pulmonary artery tumor embolism is a rare phenomenon and its diagnosis is important because of a poor prognosis. We report a 20-year-old male with history of metastatic osteosarcoma who presented with acute pulmonary embolism. He was urgently taken to the catheterization laboratory and underwent transcatheter aspiration of pulmonary artery mass using an INARI Triever aspiration catheter. Pathology of the aspirated specimen lead to the diagnosis of pulmonary artery tumor embolism, not thrombus. This case highlights the diagnostic utility of transcatheter aspiration for the pulmonary artery tumor embolism.

使用 INARI Triever 抽吸导管对肺动脉肿瘤栓塞进行诊断性经导管抽吸

肺动脉肿瘤栓塞是一种罕见的现象，由于预后不良，其诊断很重要。我们报告了一名 20 岁男性，有转移性骨肉瘤病史，表现为急性肺栓塞。他被紧急送往导管室，并使用 INARI Triever 抽吸导管对肺动脉肿块进行了经导管抽吸。抽吸标本的病理学导致肺动脉肿瘤栓塞的诊断，而不是血栓。该病例突出了经导管抽吸术对肺动脉肿瘤栓塞的诊断效用。
