RESUMEN
Objective:The purpose of this study was to investigate the clinical value of CT-guided localization of pulmonary nodules with soft wire hook-wire by trailing technique.Methods:The clinical data of 211 pulmonary nodules of 185 patients from November 2020 to March 2022 in Beijing Aerospace General Hospital were retrospectively analyzed. The pulmonary nodules were localized with soft wire hook-wire by trailing technique before video-assisted thoracic surgery (VATS). The success rate, complications, pathological results and localization operations related data were statistically analyzed.Results:The success rate of localization was 97.63% (206/211), and the success rate of VATS removal was 99.53% (210/211). The average operation time was (7.19 ± 2.62) min, and the average time required for resection of lesions was 27 min (10 to 126 min). During the surgery, the soft wire hook-wire of two patient was found to be dislocated and retracted into the chest wall. The pulmonary nodules were successfully located and removed according traces left by puncture points on the lung surface. It was found that the hook-wire was located in the interlobar fissure in 3 patients. The pulmonary nodules were successfully removed by the hook-wire position and appropriately expanding the resection range. A minor pneumothorax occurred in 49 patients, but no closed drainage was needed; 12 patients developed intrapulmonary hematoma; 15 patients with chest pain were treated with analgesia.Conclusions:For small pulmonary nodules requiring thoracoscopic surgery, the computed tomography-guided pulmonary nodule localization with soft wire hook-wire by trailing technique is more convenient, safe and effective, and is worthy of promotion to use.
RESUMEN
Venous thromboembolism (VTE) is a preventable perioperative complication of malignant tumor in thoracic surgery. At present, low molecular weight heparin anticoagulants are the first choices for perioperative drug prevention of malignant tumors, and direct oral anticoagulants are not recommended for perioperative use of malignant tumors in thoracic surgery, but their application in other related fields is relatively mature. This article will introduce direct oral anticoagulants and analyze the prospect of their perioperative application in patients with thoracic malignant tumors. It is helpful to better understand the relevant contents of "perioperative VTE prophylaxis in thoracic cancer patients: Chinese experts consensus (2018 edition)".
