Correlation between CTA obstruction score and %FEV1.0. The CT angiogram obstruction score was defined as the total score of each sub-segmental pulmonary arteries (score 0: no thrombi; score 1: the artery was narrowed by chronic thrombi but contrast medium passed to distal areas; score 2: the artery was obstructed by chronic thrombi and contrast medium did not pass to distal areas). Significant correlation was observed between CTA obstruction score and the %FEV1.0
