Subpleural nodules in the anterior basal segment of the lower lobe of the right lung are generally good for surgery. Subpleural nodule in the anterior basal segment of the lower lobe of the right lung is an imaging finding, and the subpleural nodule suggests that the location of the nodule is more peripheral and located under the pleura, which is generally not difficult to operate. According to the anatomical structure of the lungs, there are 2 lobes on the left side and 3 lobes on the right lung, and both the right and left lungs are divided into 10 lung segments, with 3 segments in the upper lobe of the right lung, 2 segments in the middle lobe, and 5 segments in the lower lobe. The lower lobe included the apical segment, medial base segment, anterior base segment, lateral base segment, and posterior base segment, and the anterior (basal) base segment was located in the lateral anterior position of the diaphragmatic surface of the lower lobe. During right lung surgery, the right lung was atrophied, because the thoracoscopic surgical entrance was in the thoracic 5-7 intercostal space, and the anterior basal segment of the lower lobe of the right lung was in the center of the field of vision, so it was easy to find the location of the lesion, and it was relatively easy to complete the operation. If wedge resection is performed at the lesion, it is a better operation. If a patient finds a subpleural nodule in the anterior basal segment of the lower lobe of the right lung, it is recommended that the patient consult a doctor in time, because if the nodule is malignant, it may further invade the pleura, and then it is not easy to operate.
