Tracheal research covers two main areas of interest: tracheal reconstruction and tracheal fixation. Tracheal reconstructions are aimed at rearranging or replacing parts of the tracheal tissue using implantation and transplantation techniques. The indications for tracheal reconstruction are numerous: obstructing tracheal tumors, trauma, post-intubation tissue reactions, etc. Although in the past...
The elaborate branching pattern of the Drosophila tracheal system originates from ten tracheal placodes on both sides of the embryo, each consisting of about 80 cells. Simultaneous cell migration from each tracheal pit in six different directions gives rise to the stereotyped branching pattern. Each branch contains a fixed number of cells. Previous work has shown that in the dorsoventral axis, ...
Tracheal transplantation remains a challenge for General Thoracic Surgery. A large number of surgical techniques and implantable devices has been tested with poor results. In spite of that, some recent findings on tracheal revascularization and graft epithelial replacement have renewed the interest on tracheal transplantation, with special attention to graft bioengineering. However, in order to...
Abstract Background Caudal tracheal stent migration can be potentially life threatening by causing distal luminal obstruction. We present a rare double hitch stitch procedure (for prevention of stent), which is an external fixation technique in case tracheoesophageal fistula with and esophageal self-expandable metallic (SEMS). Case presentation A 50-year-old male patient who presented cough dys...
We report a case of tracheal rupture in an 84-yr-old patient after tracheal intubation. The aetiology and treatment are discussed and the recent literature is reviewed.
OBJECTIVE This paper is aimed at identifying putative morphological changes induced in the rat's tracheal mucosa by chronic hyperbaric oxygen (HBO) treatment or chronic intermittent hypoxia (CIH). STUDY DESIGN Tracheal samples were obtained from three groups of 11, 12 and 13 adult Wistar rats. The first group was submitted to 20 sessions of 100 min-long HBO treatment; the second group was sub...
Introduction: Laryngoscopy and tracheal intubation necessitate to start a surgery and induction of general anesthesia as well as the maintenance of the air way and to provide ventilation. However, Laryngoscopy and tracheal intubation may lead to hemodynamic response that appear with the symptoms of hypertension tachycardia, arrhythmia and myocardial ischemia and results in myocardial infarction...
BACKGROUND Prevention of rise in intraocular pressure (IOP) is essential in patients undergoing surgery for perforated eye injuries. Metoclopramide, a prokinetic agent, is commonly used to hasten gastric emptying in emergency surgeries. AIM To study the change in IOP after intravenous metoclopramide and to study the influence of metoclopramide on change in IOP after succinylcholine and trache...
A 57-year-old woman was referred to our hospital for further examination of a tracheal stenosis shown on computed tomography findings. Bronchoscopy revealed multiple protruding tumors in the lumen of the trachea. Cytological findings of the cell block material from pleural effusion indicated that the T-cell lymphoma was composed of pleomorphic lymphoid cells. Serum human T-cell leukemia virus t...
Key points † Optimizing tracheal sealing is of clinical interest: fluid leakage past the tube cuff plays an important role in the pathogenesis of VAP. † Tapered shaped tube cuff offering a sealing zone with reduced folds and channels is a new strategy to minimize fluid leakage past the tracheal tube cuff. † Tracheal tube cuffs made from PVC show much more and faster fluid leakage than cuffs mad...
