Abstract

Aims:  The aim of the study recognize and classify
the Tracheal Bronchus (TB) in our population.

Materials and
Methods: 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).

Conclusions: 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.

Abstract

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.
