研究目的: |
回顾性分析动脉分水岭定位法(A-WALM)、静脉分水岭定位法(V-WALM)与 CT 引导定位法(CT-GL)在不可触及肺结节术中定位中的应用效果,明确三种方法的定位成功率、操作时间、并发症发生率、医疗成本等核心指标差异;进一步结合肺裂发育程度(完全 / 不完全)、结节所在肺段(如右上叶后段、左上叶尖后段等),建立 A-WALM 与 V-WALM 的临床选择标准,为临床医生制定精准、安全、经济的肺结节定位方案提供循证依据。 |

|
Objectives of Study: |
We conducted a retrospective analysis of the application efficacy of arterial watershed localization method (A-WALM), venous watershed localization method (V-WALM) and CT-guided localization method (CT-GL) in the intraoperative localization of non-palpable pulmonary nodules, aiming to clarify the differences in core indicators including localization success rate, operation time, complication rate and medical cost among the three methods. Furthermore, combined with the degree of pulmonary fissure development (complete/incomplete) and the pulmonary segment where the nodule is located (e.g., posterior segment of the right upper lobe, apical posterior segment of the left upper lobe, etc.), we established the clinical selection criteria for A-WALM and V-WALM, so as to provide evidence-based basis for clinicians to formulate accurate, safe and economical localization schemes for pulmonary nodules. |

|
Exclusion criteria: |
1. History of severe underlying lung disease, including pneumoconiosis, active pulmonary tuberculosis, chronic obstructive pulmonary disease (COPD, pulmonary function class >= II), pulmonary fibrosis, etc.; 2. Allergy to iodine contrast agent or indocyanine green (ICG), or a history of severe drug allergy; 3. Patients requiring segmentectomy or lobectomy due to nodule characteristics (e.g., suspected invasive carcinoma with diameter >20 mm) or location (e.g., near the hilum); 4. History of previous ipsilateral lung surgery (e.g., lobectomy or segmentectomy), or conditions such as pleural adhesions or thoracic deformity that impair surgical procedure; 5. Patients with severe concomitant dysfunction of vital organs (heart, liver, kidney) or coagulation disorders rendering them unfit for surgery; 6. Incomplete medical records, such as missing documentation of localization time, complications, or pathological results. |
