AI Article Synopsis
- Tracheal bronchus (TB) is an abnormal bronchus that typically arises from the right side of the trachea and is found in about 0.45% of bronchoscopic exams according to a study conducted from 2009 to 2011.
- It’s important for clinicians to be aware of TB when planning for one lung ventilation (OLV), particularly when using a bronchial blocker for left-sided procedures.
- For patients diagnosed with TB, using a double lumen tube instead of a bronchial blocker may be more effective for achieving complete OLV.
Article Abstract
Tracheal bronchus (TB) is an aberrant, accessary or ectopic bronchus arising almost exclusively from the right side of the tracheal wall above the carina. In our center, 673 bronchoscopic examinations were performed from 2009 to 2011 in patients undergoing one lung ventilation (OLV) and 3 TB were found. The incidence of a TB at bronchoscopy was 0.45% in our research, which is consistent with the reported incidence range from 0.1-5%. The clinician should consider the possibility of anomalous right upper lobe bronchus and perform bronchoscopy prior to the right bronchial blocker insertion, when left-sided OLV using bronchial blocker is planned. Also, for the patient with TB, a double lumen tube insertion is recommended than a blocker insertion to achieve OLV completely.

The plane running between two adjacent pulmonary segments consists of a very thin layer of connective tissue through which the pulmonary vein also runs. To perform an anatomically correct segmentectomy, this segmental plane needs to be divided. Before the operation, the locations of vessels and bronchi are confirmed by three-dimensional computed tomography.

Although segmentectomy is the standard surgical procedure for small-sized peripheral non-small cell lung cancer, reports on segmentectomy for right middle robe are rare because of the anatomical feature. We report a case of an 81-year-old woman with a history of left S4 segmentectomy, left basal segmentectomy, and right upper lobectomy for multiple primary lung cancer with a part solid nodule in S4a. Owing to the increased volume of the right middle lobe following a right upper lobectomy, a right S4 segmentectomy was performed.

Background: The technical complexity of segmentectomy and preservation of lung parenchyma compared with lobectomy vary by lobe. This study evaluated the impact of non-small cell lung cancer tumor location on segmentectomy use and outcomes.
Methods: Outcomes after lobectomy or segmentectomy for cT1N0M0 (≤2 cm) non-small cell lung cancer patients stratified by tumor location in smaller (right upper/middle) vs larger (bilateral lower/left upper) lobes were evaluated with logistic regression, Kaplan-Meier curves, and Cox proportional hazards methods.

Bronchial atresia (BA) and azygos lobe (AL) are rare congenital pulmonary abnormalities in pediatric patients. We herein report an infantile case of BA combined with AL that was treated with thoracoscopic surgery. The patient was an 8-month-old boy who was preoperatively diagnosed with BA of the right upper lobe (RUL) combined with an AL using fetal magnetic resonance imaging and postnatal enhanced computed tomography.
