Definition of abbreviations: BA = bronchial artery; COPD = chronic obstructive pulmonary disease; CT = computed tomography; IPF = idiopathic pulmonary fibrosis; L = left; R = right; Tp = transplant lung.
*
Represents all measurements of all BAs (e.g., one length means one measurable BA was observed assessed). Length measurement began at the carina and followed down the bronchus as far as could be radiologically discerned.
†
Average Tp BA length vs average native BA length, P < 0.0001 by paired t test; and all measured Tp BAs vs. all measure native BA, P = 0.0005 by Mann-Whitney test.
‡
Patient had two serial CT scans and BA measurements.
