Filter by:We used a segment of cryopreserved aorta as a graft for reconstruction for long segment tracheobronchial lesion in human.
Multicenter randomized controlled trial comparing endoscopic laser resection vs dilatation in benign tracheal stenosis.
Define the actual incidence of tracheal stenosis in patients who underwent either prolonged intubation or tracheostomy and to compare incidence, clinical course and outcome between COVID-19 and non-COVID-19 patients.
This is a retrospective, observational cohort study carried out in two operative Units of the University Hospital of Modena (Italy): the Diagnostic and Interventional Bronchoscopy Unit (Unit A) and the Otolaryngology Unit (Unit B). The two units have different protocols routinely applied to treat tracheal benign stenosis. In Unit A, endoscopic treatment is performed through mechanical dilatation via rigid bronchoscopy and further stent placing while in Unit B the endoscopic treatment is performed through balloon dilatation via direct laryngoscopy. The primary purpose was to compare the efficacy of the two technique on tracheal stenosis treatment over time. Patients were defined as "cured" if during the 2 years after 12 months since the last intervention they did not present any of the following: respiratory symptoms, need for a re-intervention or stenosis instability.
1. To estimate the importance of bronchoscopic treatment of tracheal stenosis and its effectiveness and safety. 2. To diagnose and evaluate tracheal stenosis characteristics as location, vertical extension and severity of obstruction.
Pulmonary artery sling is a rare congenital pulmonary vascular malformation, often associated with tracheal or bronchial stenosis. Surgical treatment of pulmonary artery sling with tracheal stenosis has a high risk and a relatively poor prognosis. This article aims to explore the relationship between the index of tracheal and left pulmonary artery stenosis and the surgical effect of pulmonary artery sling with tracheal stenosis. Methods: Retrospective analysis of the cases of pulmonary artery sling surgery in our center from January 2010 to December 2018. Before operation, routine cardiac enhancement CT examination was performed, and the diameter of the left pulmonary artery and the tracheal stenosis were measured on the CT tomogram respectively, and the ratio of the degree of tracheal stenosis / left pulmonary artery stenosis (T / P) was calculated, combining the surgical method and clinical prognosis analyzed and discussed.
The aim of this study is to evaluate the effect of high-flow nasal cannula oxygen administration on maintenance of oxygenation and removal of carbon dioxide during apnoeic period in pediatric patients undergoing general anesthesia with rigid bronchoscopy
In this study, we used the covered metallic segmented airway stent to treat malignant strictures involving carina and bronchi distal to carina and aimed to determine the feasibility, efficacy and safety of this technique.
The investigators propose a preliminary study performing exome sequencing on samples from patients and their biologically related family members with tracheal and esophageal birth defects (TED). The purpose of this study is to determine if patients diagnosed with TED and similar disorders carry distinct mutations that lead to predisposition. The investigators will use advanced, non-invasive magnetic resonance imaging (MRI) techniques to assess tracheal esophageal, lung, and cardiac morphology and function in Neonatal Intensive Care Unit (NICU) patients. MRI techniques is done exclusively if patient is clinically treated at primary study location and if patient has not yet had their initial esophageal repair.
The purpose of the study is to prospectively assess the use of a modified tracheal balloon dilator in children (<13 years old) with subglottic or tracheal stenosis. The hypothesis is that the device will effectively dilate the stenotic segment, whilst maintaining oxygenation (if applicable). The primary aim is to measure the stenosis prior to, and after dilatation; using diameter and the modified Myer-Cotton grading system. Secondary aims include assessment of stenosis at six-week follow-up and monitoring arterial oxygenation nadir (using peripheral plethysmography) during the procedure.
