Key result
Endovascular catheter biopsy successfully diagnoses PAS in 60% of patients without acute complications.
Why the study?
Pulmonary artery sarcoma is a rare and lethal malignancy lacking a standard diagnostic tool due to its rarity and fatality.
Is endovascular catheter biopsy a feasible and safe diagnostic modality for patients with pulmonary artery sarcoma?
Population
25 patients with histologically confirmed pulmonary artery sarcoma at a single center
Comparison
Endovascular catheter biopsy versus endobronchial ultrasonography-transbronchial needle aspiration or surgical biopsy after biopsy failure
Design
Retrospective case series

May warrant consideration for suspected pulmonary artery sarcoma when noninvasive diagnosis is uncertain; leaves open need for prospective validation before broader adoption.

Is endovascular catheter biopsy a feasible and safe diagnostic modality for patients with pulmonary artery sarcoma?
Endovascular catheter biopsy appears to be a feasible and safe diagnostic tool for pulmonary artery sarcoma when clinically indicated.
Kwon et al. (2018) conducted an observational in Pulmonary artery sarcoma (PAS) (n=25). Endovascular catheter biopsy was evaluated on Successful diagnosis of PAS. Endovascular catheter biopsy successfully diagnosed pulmonary artery sarcoma in 3 out of 5 patients (60%) without acute or fatal complications.
