Bronchus cardiacus accessorius dexter
Insights
Bronchus cardiacus accessorius dexter (BCAD), a rare bronchial anomaly, was found in 25 of 30,000 patients. While often asymptomatic, BCAD can cause significant hemorrhage and is associated with other developmental anomalies.
Area of Science:
- Medical Science
- Anatomy
- Pulmonology
Background:
- Bronchus cardiacus accessorius dexter (BCAD) is a rare congenital bronchial anomaly.
- Its clinical significance and associations are not well-established in the literature.
Purpose of the Study:
- To report the incidence of BCAD in a large patient cohort.
- To describe clinical presentations and associated anomalies of BCAD.
- To review existing literature on BCAD and its implications.
Main Methods:
- Retrospective analysis of bronchoscopic investigations in 30,000 adult patients.
- Detailed case reporting of complex BCAD presentations.
- Literature review on BCAD and associated developmental anomalies.
Main Results:
- BCAD diagnosed in 25 out of 30,000 patients (0.083%).
- One case presented with significant hemorrhage; another with multiple congenital anomalies.
- Associated anomalies included tracheobronchomegaly, mitral valve prolapse, and pectus excavatum.
Conclusions:
- BCAD is a rare anomaly, but its recognition is crucial for diagnosing persistent bronchopulmonary symptoms.
- Associated vascular anomalies require careful evaluation for surgical planning.
- Further research is needed to understand the full spectrum and management of BCAD.
Abstract:
The diagnosis of bronchus cardiacus accessorius dexter (BCAD) has occurred in 25 cases during the bronchoscopic investigations of 30,000 adult patients of the authors. In most of the cases, this bronchial anomaly has been revealed as an accessory phenomenon, nevertheless, in one of the patients, it was the source of a considerable hemorrhage. In another case reported here in detail, it occurred together with multiple developmental anomalies, such as tracheobronchomegaly, mitral valve prolapse, pectus excavatum, hypoplasy of sinus frontalis on the right side, inguinal hernia on the left side and hyperlipidemia type IV. Family analysis did not confirm the presence of any chromosomal disorders or accumulation of similar developmental anomalies. The forms and frequency of associations of the anomalies are surveyed on the basis of literary data. The recognition of BCAD is of diagnostic importance, since it may explain the persistence of some bronchopulmonary symptoms; furthermore, the exploration of the associated abnormal vascular branches may be very useful in case of an eventual thoracic surgical intervention.

Mechanism of Breathing III: The Accessory Muscles
The respiratory system is a complex network that relies on primary respiratory muscles like the diaphragm, but also involves accessory muscles to enhance lung expansion and airflow during both inhalation and exhalation.
Enhancing Inhalation with Accessory Muscles:
Accessory muscles such as the sternocleidomastoid, scalene, intercostal, and abdominal muscles are crucial when additional respiratory effort is required, such as during deep...
