Answer

This study may be helpful in ruling out chronic pulmonary thromboembolic disease, but it is rarely needed. A ventilation-perfusion scan is generally sufficient to clinically exclude significant or, more precisely, operable, chronic pulmonary thromboembolic disease.

A selective pulmonary artery angiogram in a patient with suspected pulmonary veno-occlusive disease (PVOD) offers very little additional clinically relevant information when ventilation-perfusion scan findings are normal or show a low probability for chronic pulmonary thromboembolic disease or in patients who are not suitable candidates for pulmonary thromboendarterectomy, even if they were diagnosed with chronic pulmonary thromboembolic disease.
