Increased overall pulmonary hemorrhage was observed with underlying emphysema (<jats:italic>P<\/jats:italic>=.022), non-peripheral location of the lesion (<jats:italic>P<\/jats:italic>&lt;.001), increased needle pathway (<jats:italic>P<\/jats:italic>&lt;.001), fissure penetration (<jats:italic>P<\/jats:italic>=.011), increased number of pleura penetrations (<jats:italic>P<\/jats:italic>=.024), prolonged needle time across pleura (<jats:italic>P<\/jats:italic>=.037), and decreased lesion size (<jats:italic>P<\/jats:italic>=.033). The pneumothorax rate increased with non-peripheral location of the lesion (<jats:italic>P<\/jats:italic>&lt;.007), fissure penetration (<jats:italic>P<\/jats:italic>=.021), prolonged needle time across the pleura (P=.013), and decreased lesion size (<jats:italic>P<\/jats:italic>=.002). In the logistic regression analyses for he two most common complications, the only risk factor for both alveolar hemorrhage and pneumothorax was a non-peripheral location of the lesion (<jats:italic>P<\/jats:italic>&lt;.001, OR=14.7, 95% CI=3.9\u201355.4 for alveolar hemorrhage) and (<jats:italic>P<\/jats:italic>=.001, OR=156.2, 95% CI =7.34\u20133324.7 for pneumothorax).<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION:<\/jats:title><jats:p>Most common complications of CT-CNLB were pneumothorax and pulmonary alveolar hemorrhage with a 5.7% major complication rate.
