Anchor Wire Localization Retained In Vivo for 9 Days Prior to Wedge Resection of a Ground-Glass Nodule a case report

CT-guided lung nodule localization technique have matured significantly. It has now become the standard approach for preoperative localization of pulmonary nodules before thoracoscopic resection. To date, no instance of acute-onset arrhythmia following CT-guided lung nodule localization has been reported. And there is limited experience in managing such situations. We report the case of a 71-year-old man scheduled for thoracoscopic resection of a nodule in the left lower lobe. After preoperative CT-guided localization with a novel positioning needle, the patient experienced sudden cardiac arrhythmia. Antiarrhythmic and coronary vasodilator therapy was initiated first. After the patient returned to normal sinus rhythm, the anesthesiology team recommended canceling the immediate operation. The patient was transferred to the intensive care unit for close monitoring. Following nine days of comprehensive medical management and conditioning, a thoracoscopic wedge resection of the lung was performed. During surgery, the resection margin was determined based on the positioning of the anchor wire, resulting in wedge resection of the left lower lobe. The procedure proceeded smoothly, and the patient recovered well. This case report provides a reference for similar situations in the future.
