“…The youngest patient was 7 days old and the oldest was 75 years old; among them, males had a higher proportion than females (1.9:1). Similar to some other countries, [ 3 , 10 , 14 ] tracheal bronchus is a very rare disease in Vietnam; our patients’ age fluctuated in a wide range, because we had randomly selected patients undergoing chest MDCT in the two aforementioned hospitals, most of whom had clinical symptoms related to the heart and lungs.…”

“…The tracheal bronchus that originated from the lower third of the trachea accounted for 96.0% and those that originated from the carina accounted for 4.0%. [ 14 ] According to RuchonnetMetrailler et al . (2015), patients with type I, II, III accounted for 56%, 31%, and 13%, respectively.…”

“…In the literature, many abnormalities have been reported to be associated with tracheal bronchus. [ 1 , 2 , 4 , 14 ] However, these abnormalities can be divided into two main groups: (1) cardiovascular diseases and (2) other pathologies. The incidence of these abnormalities varied widely among studies, depending on the patient group selected for the study and what diagnostic modality was used; however, generally, bronchopulmonary and cardiovascular abnormalities were easier to detect, because patients often had clinical manifestations.…”

“…The incidence of these abnormalities varied widely among studies, depending on the patient group selected for the study and what diagnostic modality was used; however, generally, bronchopulmonary and cardiovascular abnormalities were easier to detect, because patients often had clinical manifestations. [ 14 ] In this study, MDCT was used to investigate the patients with cardiovascular and respiratory symptoms; therefore, we could only detect the lesions in the lungs, trachea, bronchi, heart, and major blood vessels [ Table 2 ], but not genetic abnormalities in other organs. To sum up our point, we found that 75.0% of the patients had associated cardiovascular diseases [ Figure 6 ] and 12.5% had other pathologies.…”

Tracheal bronchus (TB) is a very rare condition, which is often associated with some other pathologies. This study was designed to characterize the morphology of tracheal bronchus and associated pathologies in Vietnamese individuals using multidetector-row computed tomography (MDCT). From August 2016 to February 2021, 16, 64-, and 128-detector-row computed tomography scanners were used to perform chest scans of 3663 patients, of whom 32 had tracheal bronchus and associated pathologies. The prevalence of tracheal bronchus was 0.9%, of which 0.6% were male and 0.3% were female. We found that one patient had bilateral tracheal bronchus (3.1%) and 31 patients (96.9%) had right-sided tracheal bronchus. Most patients (75.1%) had type II tracheal bronchus, whereas 15.6% and 6.2% had type III and type I tracheal bronchus, respectively. The average distance from the tracheal bronchus to the carina was 6.6 ± 6.4 mm. The average diameter of the tracheal bronchus was 4.4 ± 2.2 mm; the group with 2–4-mm tracheal bronchus accounted for the highest proportion (46.9%). Associated pathologies included congenital heart diseases (i.e., valvular heart disease, tetralogy of Fallot, cyanotic congenital heart disease-APSO, and aortic coarctation) (43.7%), stenosis of the bilateral pulmonary arteries (15.6%), absent left pulmonary artery (6.2%), stenosis of the right pulmonary artery (3.1%), anomalous pulmonary venous connection (3.1%), stenosis of the trachea (3.1%), stenosis of the left main bronchus (3.1%), bronchogenic cyst (3.1%), and bronchial atresia (3.1%), and the remaining 12.5% had no abnormalities. tracheal bronchus is a very rare abnormality among Vietnamese and is often accompanied by other pathologies. MDCT with a high spatial resolution and a good tissue contrast, along with contrast agent and appropriate scanning protocols, is efficient in detecting tracheal bronchus and associated pathologies.

Amaç: Bu çalışmanın amacı, popülasyonumuzdaki Trakeal Bronkusları (TB) tespit etmek ve sınıflandırmaktır. Gereç ve Yöntem: Bu retrospektif çalışmaya farklı nedenlerle torasik BT çektiren toplam 1500 hasta dahil edildi. 12 bireyde TB tespit edildi. TB'li 12 hastanın; beşi erkek, yedisi kadındı. TB prevalansı %0,8 bulundu. Kadınlarda (% 58,3) erkeklerden (% 41,7) daha sık tespit edildi. Bulgular: TB'lu 12 bireyin yedisinde displaced tip (% 58.3), ikisinde supernumarary tip (% 16.7) ve üçünde pig tip (% 25) bronkus vardı.Displaced tip kadınlar arasında en yaygın olanıdıydı. Beş erkekten ikisinde displaced tip, ikisinde pig tip, birinde supernumerary tip görüldü. Cinsiyet ve tip arasındaki ilişki istatistiksel olarak anlamlı bulunmadı (p = 0.516). TB'nin ortalama çapı 5.24 ±1.53 mm idi. Displaced ve pig bronkus tipleri arasındaki çapa göre fark istatistiksel olarak anlamlıydı (p = 0,017). Bu çalışmada ayrıca carina ve TB arasındaki mesafe de ölçüldü. Displaced tip ile pig bronkus tiplerinin carina'ya olan mesafeleri açısından fark yoktu (p = 0.067).Sonuç: TB'nin tanınması endotrakeal entübasyonda kritik öneme sahiptir. TB, tüpün yan yüzü tarafından tıkandığında, lob kollapsa uğrayabilir. Diğer yandan, yanlışlıkla entübe edildiğinde, aşırı havalanma sonucu pnömotoraks oluşabilir. Abstract ÖzEmre Can ÇELEBİOĞLU1, Selma ÇALIŞKAN2, Sinem AKKAŞOĞLU2, Hilal Göktürk Nakkaş3, İbrahim Tanzer SANCAK4Aim: The aim of the study recognize and classify the Tracheal Bronchus (TB) in our population. Material and Method:A total of 1500 patients who underwent thoracic Computed Tomography (CT) examination for different reasons were enrolled in this retrospective study. 12 patients with TB were reported. Of the 12 patients with TB; five were males and seven were females. Prevalence of TB was found to be 0.8%. It was indicated more frequently in women (58.3%) than in men (41.7%). Results:Of the 12 patients with TB seven had displaced type (58.3%), two had supernumerary type (16.7%) and three had pig bronchus (25%). Displaced type was most common among the females. Of the five males two had displaced type, two had pig bronchus and one had supernumerary type. Relation between gender and type was not found to be statistically significant (p=0.516). The mean diameter of the TB was 5.24±1.53 mm. Difference between displaced and pig bronchus types according to diameter is statistically significant (p=0.017). Distance between carina and TB was also measured in the present study. There was no difference between displaced type and pig bronchus type according to distance from carina (p=0.067). Conclusion:Recognizing the TB is critically important during endotracheal intubation. When the TB is occluded by the side of the tube the lobe may collapse. On the other hand when it is mistakenly intubated, over aeration may lead pneumothorax.
