    Abstract:
    OBJECTIVE: To determine if concomitant CT-guided biopsy and percutaneous fiducial seed placement in the lung can be performed in a selective patient population without increased complication or decreased success rates compared to either procedure alone. MATERIALS AND METHODS: An IRB approved retrospective analysis of 285 consecutive patients that underwent CT-guided placement of fiducial seeds in the lung alone (N=63), with concomitant core biopsy (N=53) or only core biopsy (N=169) was performed. Variables compared included: patient demographics, lesion size, depth from pleura, needle size, number of passes through pleura, number and size of core biopsies, number of seeds placed and technical success rates. Statistical analysis was performed using univariate and multivariate pair-wise comparisons. RESULTS: A pathologic diagnosis of malignancy was confirmed in all cases undergoing seed placement alone and seed placement with concurrent biopsy, and in 144 of the biopsy alone lesions. On univariate analysis, major complication rates were similar for all three groups as were lesion size, depth, number of pleural passes, and technical success. Pair-wise comparisons of the remaining variables demonstrated a significant younger age and smaller needle size in the biopsy only group, and less minor complications in the fiducial only group. Overall there were 80/285 (28.1%) minor and 29/285 (10.2%) major complications. All major complications leading to admission consisted of either pneumothorax or hemothorax, while minor complications included asymptomatic stable or resolving pneumothoraces, transient hemoptysis or small hemothoraces. CONCLUSIONS: A combined procedure of percutaneous pulmonary core biopsy and stereotactic seed placement can be performed without additional risk of a major complication when compared to performing these separately.
