ABSTRACT
Objective To investigate the risk factors of pneumorrhagia and pneumothorax occurring after CT-guided cutting needle biopsy for pulmonary solid nodules.Methods The clinical data and imaging materials of 320 patients with pulmonary solid nodule (≤3 cm),who received 16 G semi-automatic cutting needle biopsy,were retrospectively analyzed.Both univariate and multivariate logistic regression analysis methods were used to evaluate the risk factors of pneumorrhagia and pneumothorax.Results The incidence of needle track hemorrhage was 33.1% and the incidence of pneumothorax was 18.1%,the diagnostic accuracy for benign and malignant nodules was 99.6%.Needle track length was an independent risk factor for pneumorrhagia;every increase of 3 cm in needle track length,the risk of pneumorrhagia would increase 3.881 times,besides,the risk of pneumorrhagia had a parallel relationship with the time used for puncturing (P=0.061) as well as with the number of pleural puncturing (P=0.062).The age,lesion's location and needle-pleural angle were independent risk factors for pneumothorax.Each increase of 10 years in age,the risk of pneumothorax would increase 2.102 times.The pneumothorax risk of pulmonary lesion located at upper lung lobe was strikingly lower than that of pulmonary lesion located at lower lung lobe.Each increase of 20 degrees in needle-pleural angle,the risk of pneumothorax would increase 2.413 times.Emphysema was excluded from the equation because it had only a minute difference (P=0.086).Based on the pneumorrhagia and pneumothorax probability values,ROC curves of pneumorrhagia and pneumothorax were drawn,and AUC values of pneumorrhagia and pneumothorax were 0.753 and 0.725 respectively.Conclusion The occurrences of pneumorrhagia and pneumothorax after CT-guided cutting needle biopsy for pulmonary solid nodules are affected by many factors.Careful preoperative evaluation and skilled intraoperative manipulation can effectively reduce the incidence of pneumorrhagia and pneumothorax.
