Overview
A method of ICG counterstaining localization under target artery occlusion without cutting，It's a new method of localization of small pulmonary nodules.
Description
- This technology can replace part of CT puncture-guided positioning, which not only saves CT positioning costs for patients, but also saves time and space resources in CT room;
- The target artery occlusion technique does not cut off the blood vessels, and the operation is still a wedge resection. Compared with the standard segmentectomy/subsegmentectomy, the steps of cutting off the veins and bronchial tubes are reduced, the operation time is shortened, and the turnover rate is improved.
- There is less damage to the lung tissue, and the lung function is well preserved. The patients can be discharged in an average of 3 days after the operation, which improves the bed turnover efficiency of the department.
Eligibility
Inclusion Criteria:
- <1cm CTR≤0.75; <1.5cm CTR≤0.5; <2cm CTR≤0.25 Lung nodules
- The tumor center is located in the peripheral 2/3 area of the lung field
- Preoperative analysis and planning of watershed by 3D reconstruction
- Clinically assessed as cT1aN0M0 stage IA1/cT1bN0M0 stage IA2 (eighth edition), clinically resectable
Exclusion Criteria:
- No surgical video, no postoperative gross specimen and related distance measurement records
- The incision edge does not exceed the target nodule diameter from the nodule edge
- The resection range exceeds 50% of the preoperative planning
- Postoperative pathological staging non-pT1aN0M0 IA1 stage/pT1bN0M0 IA2 stage (eighth edition)
- Any situation where the investigator feels the need for extended resection
- Patients with chronic diseases (such as COPD, pulmonary fibrosis, silicosis) that can cause loss of lung function in patients at risk of progression or potential progression
