Observation of bronchial anatomy and variation of the middle lobe of the right lung based on three-dimensional reconstruction of lung CT.

ABSTRACT:

Purpose

To explore the anatomical types and variations of lung segments and subsegment bronchi based on CT 3D reconstruction technology, and to provide anatomical theoretical support for thoracic surgeons in terms of surgical techniques.

Methods

The 3D CT reconstructed images of 541 patients were retrospectively analyzed. We explored the anatomical structure of the bronchi in the middle lobe of the right lung, sorted out the variations, and classified them in detail according to different bronchial types.

Results

In the CT 3D reconstruction of 541 patients, the bronchial anatomical types of the right middle lobe were divided into two types. There were 530 cases (98.0%) of two-branched type and 11 cases (2.0%) of three-branched type, and no four-branched type was found
