Peripheral lung cancer in stage Ia
Conditions
Interventions
Control group:Combined intravenous and inhalation general anesthesia was used with double-lumen endotracheal intubation, single lung ventilation on the unaffected side, and collapsed lung on the affec
After 15-20 minutes, the anesthesiologist was instructed to fully puff up the lungs, ventilate the lungs on the unaffected side, and observe that the lung segment on the affected side is completely at

Eligibility
Sex/Gender
All
Age
18 Years to 65 Years
Inclusion criteria
Inclusion criteria: 1.Subjects voluntarily will participate this study and provide an informed consent form. 2.The participants are 18 to 65 years old. 3.Both FEV1 and DLCO are greater than 80% of the predicted values. 4.The diameter of the tumor to be resected is<=2 cm. Preoperative CT scans indicate that GGO is located in the target lung segment, aligning with the NCCN guidelines for pulmonary segment surgery.
Exclusion criteria
Exclusion criteria: 1.Subjects had a history of allergy to contrast media. 2.Subjects are on anticoagulant medication prior to surgery. 3.The patient presented with severe thoracic adhesions. 4.Preoperative computed tomography (CT) identified the tumor at the junction of lung segments, raising the possibility of missing the lesion during segmentectomy. 5.The patient cannot tolerate surgery due to the severe comorbidities. 6.Given the patient's severe condition and history of significant cardiovascular and cerebrovascular diseases, surgical intervention will be deemed intolerable.
