Özet

Objective: The lungs have a pair of vascular supplies, including the pulmonal artery, which carries lowpressure,

oxygen-free blood, and the bronchial artery (BA), responsible for carrying high-pressure,

oxygenated blood. Our study aimed to evaluate the normal anatomy and variations of the ABs in a group

of patients undergoing computed tomographic (CT) angiography of the thoracic aorta.

Methods: We retrospectively analyzed CT angiography images of the thoracic aorta captured between

2021 and 2022. These images were retrieved from the hospital PACS system (Sectra Workstation IDS7;

Sectra AB, Linköping, SWEDEN). Any images with motion artifacts, those that couldn’t be assessed, and

patients under 18 years of age were excluded from the study.

Results: The total number of BAs of 344 patients in our study group was 859, of which 446 (52%) were

right BAs and 413 (48%) were left BAs. When the total number of BAs was analyzed on a case basis, it was

seen that 16 (4.7%) patients had 1 BA, 141 (41%) patients had 2 BAs, 130 (37.8%) patients had 3 BAs, and

45 (13%) patients had 4 BA branches. When the thoracic aorta and intercostal-bronchial common trunk

(TICBA) were evaluated together, the most common combination was 1 right and 1 left bronchial artery

branch and no branch from the TICBA was observed.

Conclusion: Multidetector CT offers interventionalists a comprehensive vascular access map before

procedures. Understanding the variations in the BA is of great clinical
