Abstract Introduction The tracheobronchial tree exhibits a wide range of variations. The purpose of this study is the investigation of the frequency and multidetector tomographic (MDCT) findings of anatomical variations of the main bronchi and of the lobar bronchi, as well as the detection of abnormal bronchi originated from the trachea, in subjects without severe bronchial pathology. Materials...

The ability to measure airway dimensions is important for clinicians, interventional bronchoscopists and researchers in order to accurately quantify structural abnormalities and track their changes over time or in response to treatment. Most quantitative airway measurements are based on X-ray computed tomography and, more recently, on multidetector computed tomography. Quantitative bronchoscopi...

Real bronchial tree is very complicated piping system. Analysis of flow and pressure losses in this system is very difficult. Due to the complex geometry and the very small size in the lower generations is examination by CFD possible only in the central part of bronchial tree. For specify the pressure losses of lower generations is necessary to provide a mathematical equation. Determination of ...

Introduction High prevalence of obstructive lung disease has been reported in patients undergoing surgical correction of thoracic scoliosis. Airway narrowing due to spine morphology is analysed as a contributing factor. Methods Preoperative surgical planning CTs of 34 patients with right-sided thoracic scoliosis (age: 17.6±9.0) were retrospectively analysed and compared with 15 non-scoliotic ...

Introduction: Tracheobronchial foreign body removal, is a common emergent problem especially in pediatric population and it is associated with greatest challenge to the anesthesiologist as well as to the surgeon as the airway has to be shared by both. Various pulmonary changes associated with foreign body impaction also occurs. Methods: This is a retrospective analysis of foreign body removal o...

The authors reviewed their experience with therapeutic bronchoscopy for removal of tracheobronchial foreign bodies in the adult. Bronchoscopy records and collection of foreign bodies in the endoscopic department were retrospectively examined. Among 37,466 bronchoscopies performed between 1974-1998, 62 (0.2%) were performed for the removal of tracheobronchial foreign bodies. Medical history was ...

Presentation of a thymoma during pregnancy means that safe delivery becomes more challenging. We present 33-year-old pregnant woman who was diagnosed with large causing marked compression the tracheobronchial tree and right atrium. After various multidisciplinary meetings she presented for elective caesarean section at 31 weeks gestation. A combined spinalepidural anaesthesia performed, along c...
