Multidisciplinary Approach for a Relapsing Goiter with Severe Tracheal Stenosis: A Case Report in an Elderly Patient
2012
Summary Total thyroidectomy is considered the gold standard for thyroid benign pathology treatment. Unfortunately, many partial interventions carried out in the past created many complications due to the tendency of the goiter to relapse and the formation of adherences in the anterior region of the neck. A woman 72 years of age with a relapsing goiter and severe respiratory symptomatology underwent thyroidectomy. After thyroid removal, tracheal stenosis persisted, making the positioning of a T silicon prosthesis (Montgomery’s T-tube) necessary. After 60 days, the prosthesis was replaced with a new made out of the same material but with a larger diameter and a softer consistency, which was r…
Secondary Carina and Lobar Bronchi Stenting in Patients with Advanced Lung Cancer: Is It Worth the Effort? A Clinical Experience
2020
Background: The lobar airway stenting remains an endoscopic procedure not well standardized in patients with locally advanced lung cancer disease. The goal of this study was to evaluate technical feasibility, clinical outcome, and complications of different stents in patients with malignant lesions involving lobar bronchi, primary and secondary carina. Methods: Between November 2008 and October 2013, we retrospectively analyzed 146 patients with benign and malignant tracheobronchial stenosis who underwent airway stent insertion below main carina and main bronchi. Results: In all, 170 airway stenting procedures were performed on 146 patients. In all, 51 of them with malignant peripheral airw…
Tracheomalacia Repair Using Ceramic Rings
1992
Tracheomalacia resulting from tracheostomy or compressive thyroid disease often represents a difficult problem in airway management. In an attempt to improve this condition, biocompatible ceramic rings were surgically implanted in 16 patients to restore normal patency of the airway by first expanding the tracheal lumen lateral, and then in an anterior dimension. Preoperatively, patients displayed moderate to severe obstruction with marked restrictions in lifestyle, as confirmed by history, physical examination, and airway resistance studies. Additionally, three of these patients were trach-dependent at the time of implantation. Postoperatively all 16 patients have normal airway resistance p…
Computed tomography-based tracheobronchial image reconstruction allows selection of the individually appropriate double-lumen tube size
1999
Objectives: To determine whether individualized selection of double-lumen tubes or alternatives based on three-dimensional reconstruction of the tracheobronchial image from routine preoperative computed tomography (CT) scans leads to clinically appropriate choices. Design: Prospective observational study; comparison to historic controls. Setting: Anesthesia and radiology facilities of a university medical center. Participants: Forty-nine patients undergoing thoracic surgery requiring one-lung ventilation. Interventions: Three-dimensional image reconstruction of individual tracheobronchial anatomy was performed from routine preoperative spiral CT scans as well as from scans of five left-side…
Surgical management of benign tracheal stenosis.
2014
Abstract This chapter provides a step-by-step explanation of the indications, basic technique and pitfalls of tracheal surgery for cases of benign tracheal stenosis. Approach, trachea dissection and end-to-end anastomosis in tracheal surgery is described in detail. An algorithm for laryngotracheal technique selection according to different criteria (stenosis location, vocal cords status and tracheal mucosa and/or cartilaginous larynx involvement) is also depicted. Finally, a review of the most important reported series in tracheal surgery is presented.
Three-dimensional helical CT of the tracheobronchial tree: evaluation of imaging protocols and assessment of suspected stenoses with bronchoscopic co…
1996
To assess the accuracy of three-dimensional (3D) helical CT of normal airways, we evaluated different imaging protocols in test objects and patients. The clinical value of 3D helical CT was composed with bronchoscopy in patients with suspected stenoses, especially before and after endobronchial procedures.Solid test objects--one of central airways and one of peripheral airways--were scanned and assessed for volume defects and stairstep artifacts. Fifty helical studies were performed in 36 patients. We evaluated these images for visualization of segmental bronchi; frequency of artifacts; and presence, localization, and degree of stenoses. Bronchoscopic correlation was available for 40 CT exa…
Use of decellularized tracheas for airways engineering
2016
Background/Objective: Tracheal stenosis produces serious dyspnea. In some cases, a defective correction or timely intervention can lead to the death of the patient. The Hospital Clinico Universitario de Valencia is a reference hospital for the treatment of patients with airway problems exhibiting complex tracheal stenosis. Surgery is limited to a maximum length of 6-7 cm and it is not exempt of mortality (3-5%). In this study we have study the useful of decellularized porcine tracheas to be used in airway regenerative medicine. Methods: Three porcine tracheas were cut in 3 cm rings and exposed to SDS 2% for up to four weeks. Cell content was evaluated by fluorescence microscopy (DAPI) weekl…
Single-staged laryngotracheal reconstruction for idiopathic tracheal stenosis.
2013
Background This study retrospectively evaluated the results of surgically treated idiopathic tracheal stenosis. Methods Of the 220 patients surgically treated for idiopathic subglottic and tracheal stenosis in the participating hospitals, we reviewed the surgical records of all patients with idiopathic tracheal stenosis. This subgroup required resection of all of the involved mucosa but frequently had undergone more conservative treatments that damaged the tracheal mucosa and cartilage and complicated the definitive surgical treatment. Results During the study period, 60 women (93.8%) and 4 men (6.2%), who were a mean age of 50 years (range, 19 to 77 years), were surgically treated for idio…
Optimization of a decellularized protocol of porcine tracheas. Long-term effects of cryopreservation. A histological study
2021
[EN] Objective: The aim of this study was to optimize a decellularization protocol in the trachea of Sus scrofa domestica (pig) as well as to study the effects of long-term cryopreservation on the extracellular matrix of decellularized tracheas. Methods: Porcine tracheas were decellularized using Triton X-100, SDC, and SDS alone or in combination. The effect of these detergents on the extracellular matrix characteristics of decellularized porcine tracheas was evaluated at the histological, biomechanical, and biocompatibility level. Morphometric approaches were used to estimate the effect of detergents on the collagen and elastic fibers content as well as on the removal of chondrocytes from …
ENDOTRACHEAL STENT IN A CASE OF SEVERE TRACHEAL STENOSIS FROM RELAPSING GOITER
2009
Objectives:The surgical approach for tracheal complications in thyroidectomy sometimes requires tracheotomy in urgency for supporting the airways flow (especially in presence of giant goiter). Nevertheless, tracheotomy, even if necessary to guarantee the restoration of respiratory function, it can not be considered as definitive therapy in presence of alterations of trachea (i.e. stenosis) susceptible to heal. An useful help in clinical management comes by tracheal prosthesis as we showed in a case of a giant relapsing multinodular goiter. Materials and methods: A 72 yr old woman, affected by giant relapsing goiter rapidly growing, came to our observation with severe orthopnea, due to steno…
