Needle slippage from needle hub hardware during ablation

摘要

Re: Little MW, Chung D, Boardman P, Gleeson FV, Anderson EM (2012) Microwave ablation of pulmonary malignancies using a novel high-energy antenna system. Cardiovasc Intervent Radiol. Dr. Little et al. [1] report successful results for lung tumor microwave ablation. One under-appreciated technical pitfall that can be seen with microwave ablation in the lung is needle slippage and stabilization. This may become more relevant with the emergence of microwave and cryoablation needles, which often have heavy hubs, hardware, and cords exerting forces on the needle, which can change the depth or angle of insertion of the needle when it is not stabilized by the operator's hand. This may pull the needle off-angle or deeper than desired and may be more common in compliant lung tissue.
