Vascular complications from transradial percutaneous coronary intervention (PCI) are rare. We report an unusual case of stridor after PCI due to brachiocephalic artery perforation, pseudoaneurysm formation, and development of a large mediastinal hematoma with tracheal compression. Endovascular repair of the brachiocephalic artery was achieved with covered stent placement at the neck of the pseudoaneurysm. This case highlights the importance of careful guide catheter placement from the right radial approach...

Laryngotracheal stenosis refers to abnormal narrowing of the central airways from larynx to carina. It is caused by an eclectic group of conditions that include intubation-related airway stenosis, granulomatosis with polyangiitis, tracheal compression or malignancy, and congenital laryngotracheal malformations. A significant proportion of patients with this condition can be satisfactorily treated using a combination of endoscopic and open surgical techniques and when definitive treatment is not possible, most of the remaining patients can be managed with a combination of endoscopic airway maintenance, stents, T-tubes, and/or tracheostomies...

BACKGROUND: Airway stenting has been reported to be useful for patients with malignant airway stenosis as a bridge to tumor-specific therapy, such as chemotherapy and radiation therapy, as well as palliative therapy. However, its role in patients with small-cell lung cancer (SCLC), the most aggressive lung cancer subtype, is unclear. We investigated the efficacy of airway stenting for patients with airway stenosis resulting from SCLC. METHODS: All stenting procedures were performed using both rigid and flexible bronchoscopes under general anesthesia...

Modern thoracic surgery requires knowledge and skill in advanced bronchoscopic techniques. Rigid bronchoscopy remains a workhorse for the management of central airway obstruction. Dilation of tracheal strictures is now much simpler with the advent of the balloon dilator, which can be passed through a therapeutic bronchoscope. Numerous adjuncts, such as laser, argon beam coagulation, electrocautery, and cryotherapy, can be used to improve airway patency. There are now numerous stenting options for strictures that require stenting to maintain airway patency...

BACKGROUND: Benign stenosis involving laryngeal and upper tracheal structures represents a therapeutic challenge. Open surgery and endoscopic management have to be discussed by a multidisciplinary board in order to evaluate the risk and benefit for each patient. OBJECTIVE: The objective of this retrospective study was to report the experience of two French centers with transcordal silicone stents (TSS) in the endoscopic management of benign laryngotracheal stenosis (BLTS) in adults, with focus on efficacy, safety, and tolerability...

INTRODUCTION: Slide tracheoplasty is now considered gold standard treatment for long segment congenital tracheal stenosis. Outcomes are typically focused upon airway patency. Dysphagia is often reported in children undergoing cardiothoracic surgery, but not specifically after slide tracheoplasty. This study was carried out to describe the nature and prevalence of dysphagia following slide tracheoplasty for long segment congenital tracheal stenosis. METHODS: Retrospective case note review was conducted on a series of patients who underwent swallow evaluation following slide tracheoplasty between 2006 and 2014...

PURPOSE: An original technique using laparoscopic instruments in a gastric endocavitary work chamber with potential for esophagus, stomach and D1 vizualisation. The main purpose of laparagastroscopy is to improve the quality of life of the patient disabling by the esophageal tumor. This method has several advantages: providing physiological feeding, harvesting materials for histopathological examination, solving eso-tracheal fistulas concurrently with the proposed operation and hemostatic role through compression, low energy and plastic consumption, rapid socio-economic reintegration, mental psychological care of the patient...

Long-segment tracheal reconstruction remains a challenge. The ideal tracheal substitute should be an epithelialized tube to prevent stenosis and sufficiently rigid to maintain airflow patency. An autologous technique using a radial forearm free flap reinforced by rib cartilage has been recently described for tracheal reconstruction. We report here two cases of complex tracheal reconstruction with a modification of this technique, which consists of the creation of two independent skin paddles to allow the reconstruction of the trachea and a second adjacent defect (eg, cervical skin, esophagus)...

BACKGROUND: Critical central airway obstruction (CAO) requires emergent airway intervention, but current guidelines lack specific recommendations for airway management in the emergency department (ED) while awaiting rigid bronchoscopy. There are few reports of the use of noninvasive ventilation (NIV) in tracheomalacia, but its use as a temporizing treatment option in fixed, malignant CAO has not, to the best of our knowledge, been reported. CASE REPORT: An 84-year-old woman presented to the ED in respiratory distress, too breathless to speak and using her accessory muscles of respiration, with bilateral rhonchi throughout the lung fields...

Although controversy over the role of flexible versus rigid bronchoscopy for airway foreign body management persists, the effort should focus on prevention of aspiration of foreign bodies instead. This article discusses several recent advances in the bronchoscopic management of congenital tracheal stenosis, pediatric airway stenting, and the use of different types of lasers in children. The lack of randomized clinical trials leaves pediatric interventional bronchoscopic procedures without much national or international standards or guidelines...

Malignant stricture and fistula of the esophagus and tracheobronchus adversely affect the quality of life(QOL)in patients with advanced esophageal cancer. Stenting is one ofthe therapies available for these patients. We investigated the outcomes ofesophagus and tracheobronchial stenting in our institution. Eight patients with advanced esophageal cancer underwent double stenting from 2010 to 2016. Among them, 4 patients underwent double stenting as planned. One patient underwent an emergency tracheal stenting because ofstenosis ofthe trachea caused by esophageal stenting...

OBJECTIVES: Currently, most of the artificial airway organs still require scaffolds; however, such scaffolds exhibit several limitations. Alternatively, the use of an autologous artificial trachea without foreign materials and immunosuppressants may solve these issues and constitute a preferred tool. The rationale of this study was to develop a new scaffold-free approach for an artificial trachea using bio-3D printing technology. Here, we assessed the circumferential tracheal replacement using scaffold-free trachea-like grafts generated from isolated cells in an inbred animal model...

The Montgomery T-tube (MTT) is a useful tool for post-tracheostomy tracheal stenosis. However, MTTs can get blocked. We present a case series of life-threatening MTT blockage, wherein a split-function option was implemented, which was a customized silicone Dumon stent above the tracheostomy to maintain both airway and phonation. This tracheostomy-customized stent combination serves the same function as an MTT, with a greater margin of safety due to the easy suctioning capacity of the tracheostomy. With a fenestrated tracheostomy and stent above, speech is effectively preserved...
