Abstract:
Objective To observe the feasibility and safety of CT-guided fine-needle assisted localization for puncturing difficult lung or liver lesions.Methods Data of 30 patients with single difficult lung or liver lesion,i.e.lesion located at difficult part for puncturing or deep lesion with diameter of 0.5-2.0 cm who underwent CT-guided 22G needle assisted localization before puncturing were retrospectively analyzed.The success rate of fine-needle assisted localization,the success rate of the first-time puncturing and the occurrence of complications were recorded.Results Among 30 difficult lesions,there were 27 lung lesions and 3 hepatic lesions,with a mean diameter of(1.0±0.4)cm.Assisted localization of difficult lesions were successfully performed with 22G needle under CT guidance at the edge of lesion,1 cm adjacent to lesion or at the puncture path,with success rate of fine-needle assisted localization of 100%,and no obvious complication happened.The followed operations included preoperative localization of 14 lung nodules,biopsy of 10 lung nodules and 3 liver nodules,as well as microwave ablation of 3 liver nodules,with the success rate of the first-time puncturing of 100%.Mild pneumothorax was observed in 3 cases(3/27,11.11%)of difficult lung lesions after biopy.No other obvious complication occurred.Conclusion CT-guided fine-needle assisted localization for percutaneous puncturing difficult lung or liver lesions was feasible and safe.
