Objective: Recently, few studies have evaluated bronchial morphometric parameters focusing on length, diameter, or angles. These can be an important indicator in various pathological processes and are essential for simulating the flow of aspiration inspired particle transport. The aim this study is to determine trachea, diameters right left main bronchus, angle carina angulations bronchus; To i...

Previously, it was demonstrated that acute (4 min) and chronic (12 d) occlusion of an extrapulmonary primary bronchus triggers pulmonary hypertension but not pulmonary hypertension syndrome (PHS, ascites) in broilers. The present study was conducted to determine whether a more prolonged period of bronchus occlusion causes PHS similar to that induced by clamping one pulmonary artery. Male and fe...

1 of 3 DESCRIPTION A 70-year-old man with mediastinal lymphadenopathy was referred to our centre for endobronchial ultrasound with transbronchial needle aspiration. During the bronchoscopic examination, two separate anatomical bronchial variances were observed: a supernumerary ‘true’ tracheal bronchus branching off from the distal right lateral wall of the trachea ( fi gure 1A ) and a displaced...

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...

To evaluate the utility of the CT bronchus sign in making a choice between transbronchial biopsy (TBB) and transthoracic needle aspiration (TTNA) as the first diagnostic procedure in a patient with a solitary pulmonary nodule (SPN), we reviewed the results of TBB and TTNA in 26 patients who had a bronchogenic carcinoma less than 3 cm, studied with thin-section CT. The patients were divided into...

Tracheal bronchus is a common anomaly that occurs in approximately 2% of people. Two children with multiple medical problems which led to endotracheal intubation are described. The hospital course for each child was complicated by persistent right upper lobe atelectasis. The presence of a tracheal bronchus was not recognized in either case initially; identification of this anatomic variant allo...

Smelt7 described several variations of the congenital anomaly which they termed tracheal lobe. Essentially, an otherwise normal right upper lobe bronchus originates above the tracheal carina or bifurcation and provides the customary three segmental divisions. There may, however, be a complete duplication of the right upper lobe bronchus by an ectopic tracheal bronchus. Usually the anterior and ...

BACKGROUND Sleeve resection and reconstruction of the bronchial corner between the upper lobar bronchus and the intermediate bronchus is technique demanding. CASE PRESENTATION A 33-year-old Chinese man suffered from recurrence of low-grade malignant mucoepidermoid carcinoma located at the orifice of upper lobar bronchus with invasion to the main bronchus nearly 1 year after he had undergone a...

The possible contribution of computed tomography (CT) in the management of patients with solitary pulmonary nodules (SPNs) or masses was reviewed retrospectively in 65 patients undergoing fiberoptic bronchoscopy (FOB). Nodules were evaluated by size, location, surface contour, and the presence in cross-section of a bronchus leading to or contained within the nodule or mass, a "positive bronchus...
