【Abstract】 Objective To evaluate the diagnostic accuracy and complications of CT-guided percutaneous pulmonary biopsy with a spring-core biopsy needle. Methods The intact data of 150 patients underwent percutaneous pulmonary biopsy with a spring-core biopsy needle under CT guidance from Jun. 1998 to Dec. 2001 were analyzed. The diagnosis of all the cases was confirmed by operation, pathology and follow-up. Results Two-hundred lung biopsies were performed in 150 cases and satisfactory tissue specimens obtained in 148 cases, the success rate being 98.7%. The diagnostic accuracy for malignant tumors and benign lesions was 93.2% and 88.7%, respectively. False-negative was 6.8% in malignant tumors and 11.3% for benign lesions. The overall accuracy rate was 91.3% and false negative 8.7%. Pneumothorax was noted in 16 cases(10.7%)and hemoptysis seen in 13 patients (8.7%). Conclusion The diagnostic accuracy is high by using CT-guided spring-core biopsy needle for percutaneous pulmonary biopsy for both malignant and benign lesions.更多还原
