Introduction: In this study, we aimed to reveal the normal anatomy and variations of the bronchial arterial system and to determine the sex distribution of these variations by retrospectively reviewing the images of patients who underwent thoracal multidetector computed tomographic angiography for various reasons.
Materials And Methods: Multidetector computed tomographic images of a total of 208 patients (151 men; mean age, 59 years) were retrospectively reviewed to assess the normal anatomy and variations of the bronchial arterial system.
Results: A total of 531 bronchial arteries (median, 3; minimum, 1; maximum, 5; mean, 2.5) were detected. The number (mean diameter) of the right bronchial arteries were higher than the left bronchial arteries (290 [1.43 mm] and 241 [1.26 mm], respectively; P < .05 for both number and diameter). The mean number (diameter) of the bronchial arteries were higher with men than with women (2.58 [1.45 mm] and 2.47 [1.32 mm], respectively; P < .05 for both number and diameter). The most common (24%) branching pattern was the combination of 1 right intercostal-bronchial trunk and 1 left bronchial artery, and, secondarily (13.46%), the combination of 2 right (1 intercostal-bronchial trunk and 1 bronchial artery) and 1 left bronchial arteries. Seventy-eight ectopic bronchial arteries were detected in 59 cases (28.3%). They most commonly originated from the aortic arch (37.2%), the descending aorta below the level of T6 (35.9%), or the aortic branches (16.7%). The number of right ectopic bronchial arteries was significantly higher than the left ectopic bronchial arteries (50 [64%] vs 28 [36%]; P < .01). The incidence of ectopic bronchial arteries was statistically higher with men versus women (45 [29.8%] vs 14 [24.6%]; P < .05).
Conclusion: The origins, numbers, diameters, and courses of the bronchial arteries can vary substantially among individuals. Multidetector computed tomographic angiography enables a detailed road map of the bronchial arterial system to interventional radiologists and thoracic surgeons.

Bronchial artery pseudoaneurysm presenting with hemoptysis and hemothorax after pulmonary lobectomy: a case report and literature review.

Background: Bronchial artery pseudoaneurysm is a rare vascular disorder, and cases of bronchial pseudoaneurysms reported after lung surgery are even rarer. The number of reported cases is very limited due to the unclear pathogenesis, lack of diagnostic criteria and treatment guidelines, and nonspecific clinical manifestations.
Case Presentation: The paper reports a case of a patient with primary lung adenocarcinoma who developed hemoptysis, chest and back pain, and right hemothorax after lobectomy.

The present meta-analysis aimed to provide the most detailed and comprehensive anatomical description of bronchial arteries (BAs) using data available in the literature. Adequate knowledge of the normal anatomy and morphological variations of BAs can be clinically significant; for example, this approach can prevent potential risks while undertaking bronchial artery embolization (BAE) procedures and, ultimately, lead to better patient outcomes. Major medical databases such as PubMed, Scopus, Embase, Web of Science, Google Scholar, and the Cochrane Library were searched.

From the Department of Interventional Treatment, First Hospital of Qinhuangdao, Qinhuangdao, Hebei, China.
Background: As a proven and preferred technique for hemoptysis, bronchial artery embolization (BAE) cannot avoid the possibility of postoperative recurrence; however, few studies have examined the causes of hemoptysis recurrence after BAE.
Objectives: Identify the risk factors for hemoptysis recurrence after BAE treatment.
Design: Retrospective.
Article Synopsis
- - Bronchial artery-pulmonary artery fistula (BPF) is a rare blood vessel issue related to conditions like congenital heart disease and usually shows up in adulthood alongside hemoptysis (coughing up blood) as a symptom.
- - Bronchial Dieulafoy disease (BDD) is another uncommon vascular anomaly involving an abnormal artery in the bronchial tree, often linked to chronic inflammation or injury.
- - This report highlights a unique case where BPF and BDD occurred together in a patient with recurrent hemoptysis, emphasizing the importance of accurate diagnosis through angiography and bronchoscopy to improve clinical understanding of these conditions.
