The diagnosis of pulmonary artery sarcoma (PAS) is challenging, and its definitive diagnosis is mainly confirmed using specimens obtained during surgery or autopsy. Endovascular catheter biopsy was performed in five patients with suspected PAS to establish a definitive diagnosis. Aspiration biopsy was performed in all patients, and forceps biopsy was performed in one patient. Three patients were diagnosed with PAS, and no definitive diagnosis was obtained in two patients with squamous cell lung carcinoma with pulmonary artery infiltration. Endovascular catheter biopsy is helpful in the diagnosis of PAS and should be performed when a tumor is suspected.

肺动脉肉瘤（PAS）的诊断具有挑战性，其确诊主要通过手术或尸检获取的标本得以证实。对5例疑似PAS的患者进行了血管内导管活检以明确诊断。所有患者均进行了抽吸活检，1例患者进行了钳取活检。3例患者被诊断为PAS，2例伴有肺动脉浸润的肺鳞状细胞癌患者未获得明确诊断。血管内导管活检有助于PAS的诊断，当怀疑有肿瘤时应进行该检查。
