title: Risk factors of complications after CT-guided percutaneous needle biopsy of lumps near pulmonary hilum.
abstract: The factors influencing the incidence of common complications (pneumothorax and pulmonary hemorrhage) of CT-guided percutaneous needle biopsy of lumps near pulmonary hilum were investigated. CT-guided percutaneous needle biopsy of lumps near pulmonary hilum was performed on 48 patients. The complications of pneumothorax and pneumorrhagia as well as the contributing factors were analyzed statistically. The major complications associated with CT-guided needle biopsy included pneumothorax (13 cases, 27.1%) and pulmonary hemorrhage (14 cases, 20.24%). χ(2) test revealed that pneumothorax was associated with the lesion size and depth of needle penetration, and pulmonary hemorrhage with the depth of needle penetration and needle retention time with a significant P value. Pneumothorax was observed in 7 cases (17.5%) out of 40 cases with diameter of mass greater than 3 cm, and in 6 cases (60%) out of 10 cases with depth of needle penetration greater than 4 cm. Additionally, pulmonary hemorrhage was identified in 12 cases (41.4%) out of 29 cases with needle retention time longer than 15 min, and pulmonary hemorrhage in 7 cases (70%) out of 10 cases with depth of needle penetration greater than 4 cm. CT-guided percutaneous needle biopsy of lumps near pulmonary hilum is safe and effective. The key factors to prevent the complications include correct evaluation of lesion size, depth of needle penetration and the needle retention time before the operation.
