Aug 5, 2023 · The tracheal bifurcation angle can have a wide range of normal values in patients and can vary significantly in serial radiographs. It is of poor diagnostic value due to the lack of sensitivity and specificity in identifying the underlying pathology.

Aug 28, 2024 · Left atrial enlargement (LAE) may result from many conditions, either congenital or acquired. It has some characteristic findings on a frontal chest radiograph. CT or MRI may also be used for diagnosis. An enlarged left atrium can have many clinical implications, such as:

The carina angle-new geometrical parameter associated with periprocedural side branch compromise and the long-term results in coronary bifurcation lesions with main vessel stenting only.

Aug 27, 2019 · The carina represents the inferior termination of the trachea into the right and left main bronchi. The carina usually sits at the level of the sternal angle and the T4/T5 vertebral level in the thoracic plane.

The carina occurs at the lower end of the trachea - usually at the level of the 4th to 5th thoracic vertebra. [3][4] This is in line with the sternal angle, but the carina may raise or descend up to two vertebrae higher or lower with breathing. The carina lies to the left of the midline, and runs antero-posteriorly (front to back). [citation ...

Apr 17, 2024 · The carina of the trachea is a cartilaginous projection of the last tracheal ring, found at the bifurcation of the trachea into the left and right main (primary/principal) bronchi. It lies in the sagittal plane and is located in line with the sternal angle, at …

Jun 9, 2015 · At present, the bifurcation angle (angle B) and carina angle (angle α) are considered to be critical geometrical angles and most widely used. Definition of bifurcation angles; A: angle A (take-off angle); B: angle B (bifurcation angle); C: angle C; α: angle α (carina angle); β: angle β.

Measurement of carina angle is a quite simple and effective method of assessing PDA. Carina angle may provide information about PDA when echocardiography cannot be done for the diagnosis.

The aim of this study was to investigate the effect of body habitus, dimensions of the thoracic cavity, location of the carina within the mediastinum, and left atrial size on tracheal carinal angle using CT scan.

Dec 1, 2009 · Carina angle (α)—the distal angle between main vessel (MV) before bifurcation and side branch (SB)—was measured pre‐ and poststenting. Clinical follow‐up 9–12 months was obtained with coronary angiography if needed.
