Analysis on Complications Associated with CT-guided Percutaneous Transthoracic Needle Biopsy

Objective To investigate the prevention and treatment of the complications due to CT-guided percutaneous transthoracic biopsy.Methods CT-guided percutaneous transthoracic needle biopsy was performed in 300 patients.The complications and the contributing factors were analyzed.The methods for the prevention and treatment of the complications were suggested.Results CT-guided percutaneous transthoracic needle biopsy was succeeded in 300 cases.The major complications associated with CT-guided needle biopsy included pneumothorax(13%)and pulmonary hemorrhage(%).Pneumothorax was associated with the lesion size,lesion location,and emphysema.Pulmonary hemorrhage was associated with the lesion size,lesion location.A small quantity of pneumothorax or pulmonary hemorrhage were not particularly treated.Conclusion The prevention of complications is important for CT-guided needle biopsy.The key factors to prevent the complications include accurate location of the lesions and skillful intra-operative puncture.
