Abstract:
Objective To explore a precise method with a microwave antenna for puncture of pulmonary nodules and analyze phenomena that affect the puncture results. Methods Clinical data of 107 cases with solitary malignant pulmonary nodules were collected, and the mean length of pulmonary nodules was 13.6±0.6 mm in CT axial position. A thread-hanging method was used to assist the puncture of pulmonary nodules. The procedure was successful when the needle was not withdrawn and inserted into the central region of the nodule. The success rate and complications of the pulmonary procedure were recorded. The incidence of the following phenomena were also documented: needle coercing, needle slipping, needle tip pushing, pulmonary nodule prolapsing, radial nodule deformation, nodular masking, and radial movement distance of needle tip. Results In all of 107 cases evaluated, the antenna puncture was successful in 101 cases (94.4%) but failed in 6 cases (5.6%). Pneumothorax and pulmonary hemorrhage occurred in 23 (21.5%) and 19 cases (17.8%), respectively. The following phenomena occurred: needle coercing in 9 cases (8.4%), needle slipping in 6 cases (5.6%), needle tip pushing in 19 cases (17.8%), pulmonary nodule prolapsing in 15 cases (14%), radial nodule deformation in 14 cases (13.1%), and nodular masking in 5 cases (4.7%). The mean radial adjusting distance of needle tip was 0.7±0.4 cm. Conclusion The thread-hanging method can assist in the accurate puncture of microwave antenna for pulmonary nodules. We should focus and deal with phenomena that may occur and affect the result of puncture.
