Common complications due to CT-guided transthoracic aspiration biopsy and the comprehension of puncture / 介入放射学杂志

ABSTRACT

Objective To analyze the complications due to CT-guided transthoracic aspiration biopsy for pulmonary lesions and discuss the role of puncture skill for reducing the complications.Methods CT- guided transthoracic aspiration biopsy was performed in 116 patients with intrapulmonary parenchymal occupied lesions from June 2006 to June 2007 in our hospital.The complications and the whole process of puncture were analyzed to obtain the experience for reducing the occurrence of complications.Results CT-guided transthoracic aspiration biopsy was succeeded in all 116 cases.The major complications included pneumothorax (15.51%),puncture tract hemorrhage(10.34%),hemoptysis(4.31%)and others(1.72%).Only 1 case of pneumothorax was treated by closed thoracic drainage and no specific treatment for others.Conclusion CT- guided transthoracic aspiration biopsy for pulmonary lesions is an efficient and safe diagnostic modality.The criteria for reducing the complications are associated with accurate localization,the correct breath training and evaluation of lesion before the operation.(J Intervent Radiol,2007,16847-849)
