CT-guided accurate localization of small pulmonary nodule with memory alloy coil before thoracoscopic resection / 中国介入影像与治疗学

ABSTRACT

Objective: To observe the value of CT-guided accurate localization of small pulmonary nodule with memory alloy coils before video-assisted thoracoscopic surgery (VATS). Methods: Totally 92 patients (102 small pulmonary nodules) underwent localization of small pulmonary nodules with memory alloy coils before VATS were enrolled. VATS was performed within 24 h after localization. The localization effect and complications were observed. Results: The success rate of localization of 102 small pulmonary nodules was 98.04% (100/102), and the operation time of localization for each lesion ranged 8 min to 45 min, with the average time of (17.26±5.92)min. The memory alloy coils of 2 patients took off from lung tissue and remained in the chest wall in VATS. After localization, the incidence of small amount of pneumothorax was 10.78% (11/102), of small amount alveolar hemorrhage was 12.75% (13/102), whereas the patients had no symptom and untreated. VATS was successfully performed for 102 small pulmonary nodules without conversion to thoracotomy. Conclusion: CT-guided accurate localization of small pulmonary nodule with memory alloy coils before VATS is effective and safe.
