Brief Summary
The right-sided double lumen endobronchial tube (R-DLT) is seldom. The principal cause of reticence for using the R-DLT are the difficult positioning of its lateral orifice in front of the origin of the right upper lobe (RUL) and the variability of the length of the right main stem bronchus (RMSB). Both the angle between the right upper lobe (RUL) bronchus origin and the RMSB and the length of the RMSB can be measured with high resolution CT-scan. These measures can be useful in clinical practice as they help to determine when a R-DLT should not be used or used with caution when facing a large variation of the angle of the RUL or a proximal implantation of a RUL bronchus .

Primary Outcomes (2)
Measurement of the length of the right mainstem bronchus
1 day
Measure of the right upper lobe bronchus antero-posterior angulation
1 day
Study Arms (1)
Thoracic CT-Scan
Measurement of the length of the right main stem bronchus and of the right upper lobe bronchus antero-posterior angulation on consecutive thoracic CT-Scan reconstruction
Interventions
Measurement of the length of the right main stem bronchus on CT-Scan
Measurement of the right upper lobe bronchus antero-posterior angulation on CT-Scan
Eligibility Criteria
Evaluation of radiological consecutives thoracic CT-Scan reconstruction in a tertiary university hearth and lung institute. Patients had CT- scan for diagnosis or follow-up purposes
You may qualify if:
- Aged 35 to 85 years old
You may not qualify if:
- Unavailable weight and height
- Tracheobronchial tree pathologies (e.g. : tracheomalacia, tracheobronchomegaly, endobronchial lesions, bronchiectasis, etc.)
- Mediastinal pathologies inducing an extrinsic compression of the tracheobronchial tree.
- Pulmonary pathologies inducing a deformation of the tracheobronchial tree (e.g.: retraction, important atelectasis, pulmonary fibrosis, chronic tuberculosis, etc.)
- Patients that have had a treatment or surgery inducing a deformation of the tracheobronchial tree (e.g.: lobectomy, pneumonectomy, radiotherapy)
- An important musculoskeletal deformity at the thoracic level
- Low-quality CT scan exams (e.g.: significant kinetic artifacts where measurements should be taken
