Measurement of the Distance Between the Corresponding Anatomical Landmarks in the Thoracic Cavity and the Incisors

• Conditions: Pulmonary Resection

• Registration Number: NCT03720405
• Lead Sponsor: Nanfang Hospital, Southern Medical University

Brief Summary

Patients who agree to receive pneumonectomy will be arranged to measure the distance from the incisors to the corresponding anatomical landmarks, including the cardia, the inferior pulmonary vein, the carina, the azygos vein, the lower edge of the aortic arch, the upper edge of the aortic arch, and the cupula of pleura through " fiber measurement method within nasogastric tube " . After building regression equations with the above data, the distance from the incisors to these corresponding anatomical landmarks could be inferred by means of indexes including height and so on.
