“…In addition, infectious agents or smoking can cause damage to the bronchial wall that might be conducive to the formation of bronchial diverticula [10]. Previous studies have demonstrated that bronchial diverticula have a significant association with COPD and smoking-related lung disease [11,12]. Sverzellati et al [12] evaluated the large population of smokers and showed that the existence of more than 3 bronchial diverticula were associated with severe functional impairment (defined by FEV 1 , FVC and FEV 1 /FVC ratio values).…”

Objective: Tracheal diverticulum (DV) is an incidental finding in thoracic computed tomography examinations. Tracheal DV may be associated with chronic cough and chronic obstructive pulmonary disease (COPD). A few studies have investigated the relationship between tracheal DV and COPD. There is still no consensus on the relationship. The purpose of this study was to determine the incidence of tracheal DV and its coexistence with bronchial DV and hyperaeration. Materials and Methods:For the study, 299 patients from a total number of 12 800 patients who underwent a thoracic computed tomography examination were included. Tracheal diverticula were evaluated for localization, size, contour, wall thickness and communication with the tracheal lumen. The association of tracheal DV with bronchial DV and hyperaeration was also noted. The relationship between tracheal DV and hyperaeration was analyzed. Results:Of the 299 patients, a total of 412 tracheal diverticula were observed. Out of these, 148 of the tracheal diverticula were in females, and 264 of the tracheal diverticula were in male patients. The incidence of tracheal DV was determined to be 2.38% in this study. In total, 400 of the tracheal diverticula (97.1%) were located at the right posterolateral aspect of the trachea, and 320 of the tracheal diverticula were associated with hyperaeration. There was no significant relation between the tracheal DV and hyperaeration. However, 84 of 412 tracheal diverticula had a bronchial DV, and 72 of 84 of these bronchial DV were associated with COPD. Statistical analysis indicated a significant correlation with COPD and bronchial DV (p<0.05). Conclusion:Tracheal DV is often asymptomatic and mostly located in the right posterolateral aspect of the trachea. Tracheal DV is more common in men than in women. The incidence of tracheal DV was 2.38% in this study. Our data demonstrate that there was no significant association between tracheal DV and COPD. However, there was a significant association between subcarinal bronchial DV and COPD.Key Words: Bronchi, Chronic Obstructive Pulmonary Disease, computed tomography, diverticula, trachea ÖzetAmaç: Trakeal divertiküller, toraks bilgisayarlı tomografi incelemesinde insidental olarak saptanır.

“…However, narrowing of the trachea in the coronal plane (saber-sheath trachea) is associated with COPD-particularly with more advanced stages of COPD (121)(122)(123). Diverticula or outpouching from the central airways may also be present; although the prevalence of bronchial diverticula is not different in patients with COPD than in control subjects (124), an increased number of diverticula is associated with a history of cigarette smoking (125) and with symptoms of cough (126).…”

“…Bronchial diverticulum was present in patients who smoked (45%). 25 In our study, 81.5% of the patients with tracheal diverticulum had a history of smoking. The number of cigarettes smoked and the size of the diverticulum were directly proportional in both studies.…”

racheal diverticulum is an air cyst commonly occurring along the right posterolateral tracheal aspect of the tracheal air column at the level of the thoracic inlet.1 It can be uni-or multilocular and its size A AB BS ST TR RA AC CT T O Ob bj je ec ct ti iv ve e: : To investigate the incidence of tracheal diverticula in routine chest tomography and the relation between the presence and size of the tracheal diverticulum and smoking. M Ma a--t te er ri ia al l a an nd d M Me et th ho od ds s: : The study included 2270 consecutive patients who underwent a thoracic computed tomography (CT) exam with Dual Source Tomography due to distinct pathological signs. The size, localization and configurations of the diverticulum were reviewed and the smoking habits of the patients were questioned followed by the classification of the subjects in 5 groups. The correlation between the presence and the size of the diverticulum and smoking was investigated with non-parametric statistical tests. R Re es su ul lt ts s: : The tracheal diverticulum was determined in 119 (5.2%) patients. The size of the diverticulum varied significantly between the groups. Of the 119 patients with diverticulum, only 22 were non-smokers; the remaining 97 patients (81.5%) were smokers. Statistical analyses revealed a clear correlation between smoking and diverticulum size. Diverticulum sizes increased in proportion with the severity of smoking. The largest diverticula were identified in the most intensive smoking group. C Co on nc cl lu us si io on n: : This study suggests that the presence and size of the tracheal diverticulum increases proportionally with smoking and the size of the diverticula may be an indicator of smoking related damage. K Ke ey y W Wo or rd ds s: : Trachea; diverticulum; tomography, X-Ray computed; smoking Ö ÖZ ZE ET T A Am ma aç ç: : Rutin göğüs tomografisinde trakeosel (trakeal divertikül) sıklığını araştırmak, trakeosel varlığı ve boyutu ile sigara kullanımı arasındaki ilişkiyi belirlemektir. G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Farklı nedenlerle toraks bilgisayarlı tomografi (BT) taraması yapılan 2270 hasta çalışmaya katılmıştır. Trakeoselin yeri, boyutu ve konfigürasyonu değerlendirilmiş, divertiküllü hastalar retrospektif olarak sigara kullanımı yönünden sorgulanmıştır. Sigara alışkanlığına göre 5 gruba ayrılan hastalarda, gruplardaki divertikülün varlığı ve boyutu ile sigara kullanma arasındaki ilişki non-parametrik testler kullanılarak araştırılmıştır. B Bu ul lg gu ul la ar r: : Çalışma grubunu oluşturan 2270 hastanın 119 (%5,2)'unda divertikül saptanmıştır. Divertiküllü hastaların 97 (%81,5)'si sigara kullanmakta, yalnızca 22'si sigara içmemektedir. İstatistiksel analizler sonucunda divertikül varlığı ve boyutu ile sigara kullanma alışkanlığı arasında anlamlı bir bağlantı gözlenmiştir. Divertikül boyutu, sigara kullanma yoğunluğu ile doğru orantılı olarak artmaktadır. En büyük divertikül boyutları en yoğun sigara içen grupta saptanmıştır. S So on nu uç ç: : Bu çalışmaya göre divertikülün varlığı ve boyutuy...
