ECMO Rescues Patients With Acute Respiratory Failure Related to GPA.

Front Med (Lausanne) 2021 28;8:671396. Epub 2021 May 28.

Department of Respiratory Medicine (Department of Respiratory and Critical Care Medicine), Xiangya Hospital, Central South University, Changsha, China.

Granulomatosis with polyangiitis (GPA) is a subtype of anti-neutrophil cytoplasmic antibody-associated vasculitis with a wide range of clinical symptoms related to the systemic involvement of small blood vessels. The respiratory system is one of the most frequently involved, and life-threatening acute respiratory failure could occur due to diffusive alveolar hemorrhage and tracheal stenosis. When maximum mechanical ventilation is unable to maintain oxygenation, extracorporeal membrane oxygenation (ECMO) should be considered as the final respiratory supportive method, if available.

Post-intubation tracheal stenosis after severe COVID-19 infection: A report of two cases.

Ann Med Surg (Lond) 2021 Jul 9;67:102468. Epub 2021 Jun 9.

Department of Thoracic Surgery, Al-Mouassat University Hospital, Damascus, Syrian Arab Republic.

Introduction And Importance: Coronavirus disease 2019 (COVID-19) is a pandemic disease that spread rapidly throughout the world and became a major public health concern. Approximately 5-12% of COVID-19 patients require admission to the intensive-care unit (ICU), where they often require oxygen therapy and prolonged intubation. Post-intubation laryngotracheal stenosis (PILS) is a complication that occurs in 10-22% of non-COVID-19 patients after prolonged intubation, while the rate of COVID-19 related PILS remains unknown.

Kishore Sandu

Clin Med Insights Case Rep 2021 28;14:11795476211020590. Epub 2021 May 28.

Department of Otolaryngology, Lausanne University Hospital CHUV, Switzerland.

During the current COVID-19 pandemic, several emerging cases of laryngotracheal stenosis following prolonged intubation and tracheostomy are being reported. The patients' pre-existing comorbidities, the disease itself and the pronation maneuvers increase the risk for endolaryngeal and tracheal damage. In this commentary, we report 4 such patients with acquired severe laryngotracheal stenosis. Read More

Perioperative instrumental swallowing evaluation in adult airway reconstruction: A retrospective observational cohort study.

Clin Otolaryngol 2021 Jun 4. Epub 2021 Jun 4.

National Centre for Airway Reconstruction, Charing Cross Hospital, London, UK.

Objectives: Airway reconstruction for laryngotracheal stenosis (LTS) encompasses several procedures. Dysphagia is a well-recognised sequela of LTS and airway surgery, however studies have employed mostly non-validated assessments post-operatively in small, heterogenous samples, perpetuating uncertainty around the contributions of LTS and its management to impaired deglutition. Consequently, considerable variation in LTS perioperative nutritional management exists. Read More

Experimental Tracheal Replacement: Angiogenesis and Null Apoptosis Promote Stenosis.

J Chest Surg 2021 Jun;54(3):191-199

Tecnológico de Monterrey, México.

Background: Tracheal replacement is a challenge for thoracic surgeons due to stenosis in the trachea-prosthesis anastomosis. We propose that stenosis occurs due to fibrosis as a result of an abnormal healing process, characterized by an increased expression of wound healing growth factors (vascular endothelial growth factor [VEGF], survivin, and CD31), which promote angiogenesis and decrease apoptosis. We analyzed the immunoreactivity of VEGF, survivin, CD31, and caspase-3 in the development of fibrotic stenosis in prosthetic tracheal replacement. Read More

Department of Thoracic Surgery, Ruhrlandklinik, University Medicine Essen, Essen, Germany.

Background:  Tracheal and laryngotracheal surgery provides both excellent functional results and long-term outcomes in the treatment of tracheal stenosis. Consequently, challenging re-resections are rarely necessary. The purpose of this study was to compare the outcome of (laryngo-)tracheal re-resection and surgery after bronchoscopic interventions with that of primary surgery. Read More

Relationship between a Tracheal and Left Pulmonary Artery Stenosis Index and the Prognosis of Pulmonary Artery Sling with Tracheal Stenosis.

Pediatr Cardiol 2021 May 27. Epub 2021 May 27.

Children's Hospital of Fudan University, National Children's Medical Center, Shanghai, China.

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 (T) has a high risk of death and a relatively poor prognosis. This study explored the relationship between the T and left pulmonary artery stenosis (P) ratio and the effects of surgery for pulmonary artery sling with tracheal stenosis. Read More

Severe central airway stenosis and tracheomalacia in hunter syndrome.

Med J Malaysia 2021 May;76(3):441-445

Hospital Kuala Lumpur, Genetic Department, Malaysia.

Hunter Syndrome is a genetic disease characterized by deficiency of Iduronate-2-Sulfatase enzyme activity, resulting in accumulation of glycoaminoglycans in various organs including the central airways. We report a case of severe tracheomalacia and airway stenosis at Hospital Sultanah Aminah, Johor Bahru, Malaysia requiring mechanical ventilation in a middle aged gentleman who was previously undiagnosed of mucopolysaccharidosis.

Pre-tracheotomy for Potentially Emergent Airway Scenarios: Indications and Outcomes.

Laryngoscope 2021 May 22. Epub 2021 May 22.

Department of Surgery, Division of Otolaryngology-Head and Neck Surgery, University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin, U.S.A.

Objectives/hypothesis: Airway access in the setting of unsuccessful ventilation and intubation typically involves emergent cricothyrotomy or tracheotomy, procedures with associated significant risk. The potential for such emergent scenarios can often be predicted based on patient and disease factors. Planned tracheotomy can be performed in these cases but is not without its own risks. Read More

Department of Thoracic Surgery, Shang Hai Pulmonary Hospital, Shanghai, China.

Background: Our study aims to explore the feasibility of uniportal video-assisted complex sleeve lung resection and summarize the surgical techniques and clinical outcomes.

Methods: From June 2016 to April 2020, a total of 20 complex sleeve pulmonary and distal tracheal resections were performed by the single surgical team at the Thoracic Surgery Department of the Shanghai Pulmonary Hospital.

Airway Surgery for Laryngotracheal Stenosis During the COVID-19 Pandemic: Institutional Guidelines.

J Cardiothorac Vasc Anesth 2021 Apr 20. Epub 2021 Apr 20.

Department of Anesthesia, intensive care and pain management, Ain Shams University, Cairo, Egypt.

Objective: The management of laryngotracheal stenosis is challenging, as patients usually require in-time interventions. The current coronavirus disease 2019 (COVID-19) pandemic has added unique challenges to this procedure. The presence of the virus in high concentrations in the aerodigestive tract and the need for an open airway during surgery can increase the risk of aerosolization of the virus and subsequent infection of the surgical, anesthetic, and operating room (OR) personnel.

Unexpected difficult tracheal intubation secondary to subglottic stenosis leading to emergency front-of-neck airway.

Anaesth Rep 2021 Jan-Jun;9(1):90-94. Epub 2021 May 9.

Department of Anaesthesia Prince Charles Hospital Llantrisant UK.

A 26-year-old woman presenting for an elective day case procedure under general anaesthesia had undiagnosed subglottic stenosis leading to a life threatening airway emergency requiring emergency front-of-neck airway. We outline the case and discuss key anaesthetic considerations in subglottic stenosis, including concerning features of a medical/anaesthetic history and the potential for rapid deterioration of a stenotic airway following manipulation. We also consider the effect of anaesthesia on the calibre of subglottic stenosis and the effects of positive pressure ventilation. Read More
