RESUMEN
Surgical resection of the stenotic segment with end-to-end anastomosis is considered the gold standard in postintubation tracheal stenosis. However, outcomes of this concrete aetiology are not well described. With the aim to examine the extent, range and characteristics of the existing evidence, a scoping review was performed. Data sources included MEDLINE, Scopus, Ovid and the Cochrane databases. Inclusion criteria consisted of studies in adult patients with postintubation tracheal stenosis that reported characteristics, surgical management and outcomes. A total of 125 articles were identified, of which 10 were included in the final analysis. All studies were case reports or case series (level 4 evidence) grouping 110 patients, 75 males and 35 females. The age ranged from 15 to 71 years. Cotton-Myer stenosis grade was 1 [1 (0.9%)], 2 [25 (22.7%)], 3 [70 (63.6%)] and 4 [14 (12.7%)]. Stenosis location was in the tracheal upper-third in 108 (98.2%), in the middle-third in 1 (0.9%) and in the lower-third in 1 (0.9%). Stenosis length ranged from 1 to 5.6 cm. Follow-up ranged from 1 to 60 months (2 years for the most). Most frequent complications were transitory dysphagia in 13 (11.3%), granuloma formation in 8 (7.3%), dehiscence or air leak in 5 (4.5%) and wound infection in 4 (3.6%). Restenosis rate ranged from 2% to 25%. There was no perioperative mortality. Tracheal resection and primary anastomosis in postintubation tracheal stenosis appear to be safe and effective in the short and mid-terms; however, the very low level of evidence found prevents definitive conclusions.

A female newborn presented with respiratory distress at birth and was diagnosed with congenital tracheal stenosis. The stenosis was positioned at the distal trachea and compromised the carina and the right and left bronchi. She underwent surgical treatment using circulatory life support with veno-arterial peripheral extracorporeal membrane oxygenation, and the airway was reconstructed using the slide tracheoplasty technique to build a neocarina. The patient had an excellent postoperative course, was successfully weaned from extracorporeal membrane oxygenation and invasive ventilation, and was discharged.

Introducción: La infección por SARS-CoV-2 puede presentar síndrome de distrés res-piratorio agudo con requerimiento de ventilación mecánica prolongada y retraso en la realización de traqueostomía. Esto trae como consecuencia un incremento en casos de estenosis traqueal y la necesidad de métodos menos invasivos para su abordaje. Métodos: Estudio descriptivo de corte transversal, desde marzo 2020 hasta diciem-bre 2021 en el Hospital Universitario Nacional de Colombia, en adultos con estenosis traqueal postintubación asociado SARS-CoV-2. Se realizó análisis univariado entre los grupos con infección o no por SARS-CoV-2 como control, y reintervención, grado de estenosis, uso de inyección intramucosa con dexametasona intratraqueal o múltiples estenosis como desenlaces de importancia. Se usó test exacto de Fisher, t Student y Man-Whitney según la naturaleza de variables. Se consideró p estadísticamente significativo menor a 0.05.Resultados: Se identificaron 26 pacientes, 20 tenían COVID-19 y 6 no. Se encontraron diferencias en edad (p=0,002), epilepsia (p=0,007) y estenosis múltiple (p= 0,04). En 85% de los casos se utilizó láser blue más dilatación con balón pulmonar, en 35% inyección intramucosa con dexametasona intratraqueal y reintervención en 35%, sin diferencias significativas entre grupos. Conclusiones: Se observó un incremento tres veces mayor de pacientes con estenosis múltiple en el grupo de infección por COVID-19, así mismo se encontró que el método más utilizado en este grupo para la recanalización fue el uso de láser blue más dilatación con balón pulmonar y la innovación en el uso de inyección intramucosa.
Introduction: SARS-CoV-2 infection can lead to acute respiratory distress syndrome with a prolonged need for mechanical ventilation and delayed tracheostomy, resulting in an increase in cases of tracheal stenosis and the necessity for less invasive approaches.Methods: A descriptive cross-sectional study was conducted from March 2020 to December 2021 at the Hospital Universitario Nacional de Colombia, focusing on adults with post-intubation tracheal stenosis associated with SARS-CoV-2. Univariate analysis was performed between groups with or without SARS-CoV-2 infection as a control, considering reintervention, degree of stenosis, use of intratracheal steroids, or multiple stenoses as important outcomes. Fisher's exact test, Student's t-test, and Mann-Whit-ney test were employed based on the nature of variables. A p-value less than 0.05 was considered statistically significant.Results: A total of 26 patients were included, with 20 having COVID-19 and 6 without. Significant differences were found in age (p=0.002), epilepsy (p=0.007), and multiple stenosis (p=0.04). In 85% of cases, laser blue plus balloon pulmonary dilation was used, intratracheal dexamethasone in 35%, and reintervention in 35%, with no significant differences between groups.Conclusions: A threefold increase in subglottic stenosis was observed during the SARS-CoV-2 pandemic, with more instances of multiple stenosis and predominantly the use of laser blue plus balloon pulmonary dilation as a successful recanalization technique. There was a higher use of intratracheal dexamethasone in this group compared to oth-er pathologies causing tracheal stenosis.

OBJECTIVE: To assess management strategies for pediatric patients with the challenging combination of congenital heart diseases (CHDs) and airway anomalies. STUDY DESIGN: Patients diagnosed with CHD and airway anomalies in the Pediatric Cardiac Surgery Centre of Fuwai Hospital from January 2016 to December 2020 were included in this retrospective study. Patients were divided into three groups based on different management, including the conservative group, the slide group (slide tracheoplasty), and the suspension group (suspension with external stenting). Patients' data and computed tomography measurements from medical records were reviewed. RESULTS: A total of 139 patients were included in the cohort; 107 had conservative airway treatment (conservative group), 15 had slide tracheoplasty (slide group), and 17 had tracheal suspension operation (suspension group). The top three associated intracardiac anomalies were ventricular septal defect (n = 34, 24%), pulmonary artery sling (n = 22, 16%), and tetralogy of Fallot (n = 15, 11%). Compared with patients with conservative airway management (100 minutes [median], 62-152 [IQR]), the extra airway procedure prolonged cardiopulmonary bypass duration, with 202 minutes (IQR, 119-220) for the slide group and 150 minutes (IQR, 125-161) for the suspension group. Patients who underwent slide tracheoplasty required prolonged mechanical ventilation (129 minutes [median], 56-328 [IQR]). Of the total cohort, 6 in-hospital deaths, all in the conservative group, and 8 mid-to long-term deaths, with 6 in the conservative group, occurred. CONCLUSIONS: Both conservative and surgical management of CHD patients with airway anomalies have promising outcomes. Extra tracheobronchial procedures, especially the slide tracheoplasty, significantly prolonged cardiopulmonary bypass duration. Based on multidisciplinary team assessment, individualized management strategies should be developed for these patients.

Tracheal luminal stenosis can cause clinical respiratory distress in wild birds. We describe a case of tracheal stenosis due to diffuse ossification with osteopetrosis of tracheal rings in a yellow-crowned parrot (Amazona ochrocephala) with a history of chronic respiratory distress and death after development of marked dyspnoea. An ante-mortem radiographic examination revealed that the tracheal rings were radiopaque and that there were multiple areas of osteopenic change in long bones. At necropsy, there was stenosis of the tracheal rings characterized by complete replacement of cartilage by thickened compact bone with osteopetrosis and bone necrosis. The clinical respiratory distress and death of the parrot were associated with tracheal luminal stenosis due to thickening of the tracheal rings by diffuse ossification with osteopetrosis.

Introducción: la infección por COVID-19 afecta el tracto aerodigestivo superior a través de la enzima convertidora de angiotensina 2 (ECA2) y/o la proteasa transmembrana serina 2 (TMPRSS2). Sus manifestaciones agudas y secuelas han sido muy variadas y no todas están relacionadas con la intubación orotraqueal. El objetivo es describir las características sociodemográficas, clínicas y los hallazgos endoscópicos de los pacientes con síntomas laringofaríngeos posteriores a una infección por SARS-CoV-2 evaluados en el Hospital Militar Central y Hospital Universitario Clínica San Rafael entre marzo de 2020 y marzo de 2022. Materiales y métodos: estudio observacional de corte transversal con datos sociodemográficos, comorbilidades, necesidad de intubación orotraqueal, variedad de síntomas y sus hallazgos endoscópicos. Resultados: se recolectaron datos de 118 pacientes; la edad media fue de 51 años ± 14,4. El síntoma más frecuente fue la disfonía (69,5 %), seguido de la disnea (39,8 %). El 58,9 % requirió intubación orotraqueal y, de estos, la manifestación más frecuente fue disfonía por tensión muscular (DTM) y estenosis subglótica-traqueal. En el 41,1 % restante su hallazgo más frecuente fue la laringitis irritativa. Conclusiones: la COVID-19 tiene múltiples manifestaciones laringofaríngeas en relación con su mecanismo de infección e invasión en los tejidos de esta zona, de tipo inflamatorio y estructural, y no todos están relacionados con la intubación.
Introduction: COVID 19 infection affects the upper aerodigestive tract through angiotensin-converting enzyme 2 (ACE2) and/or Transmembrane serine protease 2 (TMPRSS2). Its acute manifestations and sequelae have been very varied, and not all of them are related to orotracheal intubation. The objective is to describe the sociodemographic and clinical characteristics and the endoscopic findings of patients with laryngopharyngeal symptoms after SARS-CoV-2 infection evaluated at the Hospital Militar Central and Hospital Universitario Clínica San Rafael between March 2020 and March 2022. Methods: Cross-sectional observational study, obtaining sociodemographic data, comorbidities, need for orotracheal intubation, variety of symptoms and their endoscopic findings. Results: 118 patients were collected; the mean age was 51 years ± 14.4. The most frequent symptom was dysphonia (69.5%), followed by dyspnea (39.8%). 58.9% required orotracheal intubation and of these the most frequent manifestation was muscular tension dysphonia (MTD) and subglottictracheal stenosis. In the remaining 41.1%, the most frequent finding was irritative laryngitis. Conclusions: COVID-19 has multiple laryngopharyngeal manifestations in relation to its mechanism of infection and invasion in the tissues of this area, as an inflammatory and structural type, and not all of them are related to intubation.

Abstract Stenting for lower tracheal stenosis is a tricky situation and for the safe conduct of anesthesia, it is imperative to maintain spontaneous respiration. Airway topicalization is routinely recommended for anticipated difficult airway. We report a case of upper airway obstruction following lidocaine nebulization in a patient to be taken for tracheal stenting for lower tracheal stenosis. We would like to highlight that close monitoring of the patient is advisable during airway topicalization to detect any airway obstruction at the earliest and how fiberoptic intubation can play a pivotal role to secure the airway in an emergency scenario.

Introducción: La rápida propagación del SARSCoV2 ha provocado una pandemia mundial. Si bien puede salvar vidas, la intubación traqueal presenta el riesgo inherente de inducir daño en la mucosa traqueal con estenosis, con una incidencia estimada de 4,9 casos por millón cada año. Objetivo: Caracterizar la presentación de una estenosis traqueal por intubación prolongada en un paciente que sufrió neumonía grave por coronavirus. Presentación del caso: Se asiste a un paciente de 55 años que sufrió neumonía grave por coronavirus y necesitó intubación orotraqueal prolongada. Una vez recuperado comienza con disnea de empeoramiento progresivo. Se diagnostica una estenosis traqueal y se decide tratamiento quirúrgico donde se realiza resección y anastomosis. El paciente no presentó complicaciones y evolucionó satisfactoriamente. Conclusiones: La estenosis traqueal debe reconocerse como una complicación potencial, aun cuando los pacientes se recuperan de una neumonía grave por COVID-19. El diagnóstico definitivo de estenosis traqueal se realiza mediante fibrobroncoscopia. La resección traqueal con anastomosis entre tráquea y tráquea es el procedimiento más comúnmente realizado(AU)
Introduction: The rapid spread of SARS-CoV-2 has resulted in a global pandemic. Although tracheal intubation can save lives, it presents the inherent risk of inducing tracheal mucosal damage with stenosis, with an estimated annual incidence of 4.9 cases per million. Objective: To characterize a case of tracheal stenosis due to prolonged intubation in a patient with severe coronavirus pneumonia. Case presentation: A 55-year-old patient who suffered severe coronavirus pneumonia and required prolonged orotracheal intubation was attended. Once recovered, the patient began with progressively worsening dyspnea. Tracheal stenosis was diagnosed and surgical treatment was decided, in which resection and anastomosis were performed. The patient did not present any complications and evolved satisfactorily. Conclusions: Tracheal stenosis should be recognized as a potential complication, even when patients recover from severe COVID-19 pneumonia. A definitive diagnosis of tracheal stenosis is made by fibrobronchoscopy. Tracheal resection with anastomosis between trachea is the most commonly performed procedure(AU)

Desde la aparición de la enfermedad por SARS-CoV-2, han cambiado paradigmas en la ciencia médica y actualmente nos enfrentamos a las repercusiones a largo plazo que algunos de los pacientes desarrollan. Entre el grupo de pacientes que han cursado con neumonía severa-síndrome de dificultad respiratoria aguda (SDRA) por SARS-CoV-2 y que requirieron intubación orotraqueal (IOT), se documentan complicaciones multisistémicas (1-4). En este artículo destacaremos las complicaciones relacionadas con la vía aérea que se presentan en forma de estenosis benignas, siendo las lesiones subglóticas tipo simples o complejas las más frecuentes. A continuación, presentamos el caso de un paciente que presentó estenosis traqueales pos-IOT a causa de una neumonía severa por COVID-19 con diagnóstico, seguimiento y manejo por un grupo multidisciplinario de vía aérea.
Since the appearance of SARSCoV-2 disease, paradigms have changed in medical science, and we are currently facing the long-term repercussions that some of the patients develop. Within the group of patients who have had severe pneumonia - Acute respiratory distress syndrome (ARDS) due to SARSCoV-2 and who required orotracheal intubation (OTI), multisystemic complications are documented (1-4), in In this article, we will highlight airway-related complications that occur in the form of benign stenosis, with simple or complex subglottic lesions being the most common. We present a case of a patient who presented tracheal stenosis post-OTI due to severe COVID-19 pneumonia as main diagnosis, follow-up, and management by a multidisciplinary airway group.

BACKGROUND: Tracheal stenosis (TS) is a complication of prolonged intubation, tracheotomy, and tracheal surgery that compromises the vascular supply. Animal models are essential for studying its pathophysiology and the effect of interventions. OBJECTIVE: To establish a TS model in rats secondary to tracheal autotransplantation with a graft submerged in bleomycin (Atx-Bleo). Additionally, to evaluate the clinical and histological changes, as well as the expression of newly formed collagen (NFC), isoforms of transforming growth factor beta (TGFß), fibronectin (FN), elastin (ELN), integrin ß1 (ITGß1), and matrix metalloproteinase 1 (MMP1) in TS. METHODS: Twenty Wistar rats were divided into three groups: group I (n = 20) control; group II (n = 10) end-to-end anastomosis of the trachea (tracheoplasty); and group III (n = 10) Atx-Bleo. The animals were evaluated clinically, tomographically, macroscopically, morphometrically, and microscopically. NFC deposition, and the expression of profibrotic and antifibrotic proteins were evaluated in tracheal scars. RESULTS: All animals survived the surgical procedure and the study period. Compared with the other study groups, the Atx-Bleo group developed TS and fibrosis, exhibited higher expression of NFC, TGFß1, TGFß2, FN, ELN, and ITGß1, and mild expression of TGFß3 and MMP1 (p < 0.005; analysis of variance, Dunnett and Tukey tests). CONCLUSION: Atx-Bleo in TS model rats produces tomographic and histological changes, and induces the upregulation of profibrotic proteins (TGFß1, TGFß2, collagen, FN, ELN, ITGß1) and downregulation of antifibrotic proteins (TGFß3, MMP1). Therefore, this model may be used to test new pharmacological treatments for reversing or preventing TS, and conduct basic studies regarding its pathophysiology.

El complejo ring-sling es una asociación entre el sling de la arteria pulmonar y la estenosis traqueal congénita por anillos traqueales completos. El sling de la arteria pulmonar es una forma rara de anillo vascular dentro de las cardiopatías congénitas. Se presenta el caso clínico de un niño con estridor laríngeo asociado a dificultad respiratoria evaluado en otro centro, donde se realizó endoscopia respiratoria y se observó compresión traqueal extrínseca. Ante la sospecha clínica de anillo vascular, se solicitó angiotomografía computada (angioTC) y se confirmó diagnóstico de sling de arteria pulmonar. Fue derivado a nuestro hospital y durante la intervención quirúrgica se realizó nueva endoscopia respiratoria y traqueobroncografía. Se llegó al diagnóstico de estenosis traqueal congénita con bronquio derecho accesorio (pig bronchus) y anillos vasculares completos, ambos reparados en el mismo acto quirúrgico.
The ring-sling complex is an association between pulmonary artery sling and congenital tracheal stenosis. Pulmonary artery sling is a rare form of vascular ring in congenital heart disease. The clinical case of a child with inspiratory laryngeal stridor associated with respiratory distress is presented, evaluated in another center where respiratory endoscopy was performed, observing extrinsic tracheal compression. Given the clinical suspicion of a vascular ring, CT angiography was requested, confirming the diagnosis of pulmonary artery sling. He was referred to our hospital and during the surgical intervention a new respiratory endoscopy and tracheobronchography were performed, reaching the diagnosis of congenital tracheal stenosis, right accessory bronchus (pig bronchus) and complete vascular rings, both repaired in the same surgical act.

BACKGROUND: Perioperative management of Tracheal Resection and Reconstruction (TRR) presents many challenges to the physicians involved in airway management. Factors related to postoperative outcomes can be identified as early as the preoperative setting and can even be linked to demographic characteristics of patients affected by tracheal stenosis. The primary aim of this study is to describe the experience of patients undergoing TRR at our hospital from an anesthesiology perspective, describing as a second aim demography, preoperative conditions, and postoperative complications. METHODS: This was a single institution retrospective review of patients who underwent TRR between 2009 and 2020. We did a post-hoc exploratory analysis to identify possible associations between perioperative complications and perioperative management. RESULTS: Forty-three ASA I-IV adult patients aged 18-72 years who underwent TRR were included. Prolonged intubation (72%) is the primary cause of tracheal stenosis. Intraoperative management: intravenous induction and laryngeal masks are now the most frequently used for airway management, especially in subglottic stenosis. Perioperative complications were vocal cord paralysis (25.6%), postoperative ventilatory support (20.9%), and need for surgical reintervention (20.9%). One patient (2%) died in the postoperative period due to anastomotic complication. After resection, dexmedetomidine is the preferred choice (48.8%) for sedoanalgesia in the ICU. CONCLUSIONS: Perioperative management of TRR at our hospital has a low mortality and high morbidity rate. We did not find an association between perioperative anesthetic interventions and postoperative complications. Further studies are needed to evaluate which anesthetic interventions may be associated with better outcomes.

BACKGROUND: The clavicle is a long bone that forms the anterior border of the thoracic inlet. Anatomic abnormalities of the clavicle can lead to compression of the innominate artery and trachea due to mass effect. These anatomic abnormalities can be amenable to surgical resection, which can provide complete resolution of symptoms. METHODS: We present a case of tracheal compression by the innominate artery in an adult man, caused by a clavicular abnormality due to an underlying bone mineralization disorder, corrected by partial resection of the right clavicle. RESULTS: The patient underwent successful open surgical resection of his right clavicular head leading to resolution of his tracheal compression by the innominate artery. CONCLUSIONS: We believe that this is the first description of tracheal compression due to osteomesopyknosis. This case demonstrates that compression of the innominate artery due to a clavicular abnormality can be safely corrected via open surgical resection.

INTRODUCTION: The Montgomery T-tube is a device used as a combined tracheal stent and tracheostomy tube to prevent post-operative tracheal stenosis. OBJECTIVES: The purpose of this retrospective study is to evaluate the outcome following Montgomery T-tube stenting performed in for neck and airway injury in patients with acute blunt laryngotracheal trauma over a period of 12 years. METHODS: Between 2005 and 2017, 19 patients with acute blunt laryngotracheal trauma underwent Montgomery T-tube stenting. All 19 laryngotracheal trauma patients had undergone a preoperative tracheostomy in the emergency department by an ENT surgeon. Montgomery T-tube stenting was done later through an external approach. The follow up period ranged from 2 to 10 years. The Montgomery T-tube was removed after a period ranging from 6 months to 1½ year. RESULTS: The majority of patients in the study were in the age group of 21-30 years. A preoperative tracheostomy was done in all 19 patients. All patients except 3 underwent successful decannulation, and experienced long-term satisfactory result. CONCLUSION: Management of acute blunt laryngotracheal trauma is a challenging problem that demands a multidisciplinary approach. The ideal treatment option should be individualized according to the patient's condition and characteristics of injury. According to our study we suggest that cases of acute blunt laryngotracheal trauma patients should be managed following the protocol as mentioned in our study, and we strongly emphasize that Montgomery T-tube should be left for at least 1 complete year in the airway as it results in negligible chances of post-traumatic stenosis of airway later.

Introducción. La causa más común de estenosis laringotraqueal benigna es iatrogénica, secundaria a intubación orotraqueal. El manejo quirúrgico sigue siendo la alternativa que ha mostrado mejores resultados a largo plazo. El objetivo de este estudio fue analizar la experiencia en el manejo quirúrgico de la estenosis laringotraqueal durante 15 años en un hospital de alta complejidad en Colombia.Métodos. En este estudio se revisaron las historias clínicas de todos los pacientes tratados con reconstrucción de estenosis traqueal benigna, entre los años 2005 y 2020. Para el análisis estadístico se usaron métodos de estadística descriptiva, con análisis de frecuencias y medidas de tendencia central o de dispersión.Resultados. Se identificaron 38 pacientes con estenosis laringotraqueal, con un grado variable de estenosis. La nasofibrolaringoscopia fue bien tolerada y segura para determinar el grado y la longitud de la estenosis. El uso de tomografía sirvió para determinar la extensión y las características anatómicas. Los resultados del presente estudio son similares a los de la literatura en cuanto a complicaciones, mortalidad y falla de la anastomosis. Las complicaciones más frecuentemente reportadas son reestenosis, infección del sitio operatorio, lesión nerviosa y fístula, que en general se presentan en un tercio de los pacientes. Conclusiones. La experiencia de manejo quirúrgico de estenosis laringotraqueal en este hospital permite concluir que la reconstrucción traqueal es una opción segura en nuestro medio. Las tasas de éxito y de falla del tratamiento son equiparables a las reportadas en la literatura.
Introduction. The most common cause of benign laryngotracheal stenosis is iatrogenic, secondary to orotracheal intubation. Surgical management continues to be the alternative that has shown better long-term results. The objective of this study was to analyze the experience in the surgical management of laryngotracheal stenosis for 15 years in a high-level complexity hospital in Colombia.Methods. Medical records of patients treated with reconstruction of benign tracheal stenosis between 2005 and 2020 were reviewed. Descriptive statistical methods were used, with frequency analysis and measures of central tendency or dispersion.Results. Thirthy-eight patients with laryngotracheal stenosis were identified, with a variable degree of stenosis. Nasofibrolaryngoscopy was well tolerated and safe to determine the degree and length of the stenosis. The use of tomography served to determine the extension and anatomical characteristics. The results of the present study are similar to those of the literature in terms of complications, mortality and failure of the anastomosis. The most frequently reported complications are restenosis, surgical site infection, nerve injury, and fistula, which generally occur in one third of patients.Conclusions. The experience of surgical management of laryngotracheal stenosis in our hospital allows us to conclude that tracheal reconstruction is a safe option in our environment. Treatment success and failure rates are comparable to those reported in the literature.

INTRODUCTION. Airway abnormalities are rare but potentially fatal. Stridor is a res-piratory noise with greater predominance in the inspiratory phase. OBJECTIVE. To evaluate the etiology of stridor, determine its comorbidities and mortality. MATERIALS AND METHODS. Retrospective cross-sectional study. Population of 110 and sample of 33 data from the Medical Records of neonatal or infant patients who presented stri-dor at the Carlos Andrade Marín Specialties Hospital of Quito-Ecuador, from january 2009 to december 2020. RESULTS. The 51,51% (17; 33) of cases were men. The age of the first consultation for stridor was within the first month in 18,00% (6; 33) and 40,00% (13; 33) at 3 months. The most frequent congenital laryngeal patholo-gy was: laryngomalacia 81,82% (27; 33), followed by subglottic stenosis 9,09% (3; 33), bilateral chordal paralysis 6,06% (2; 33) and tracheal stenosis 3,03% (1; 33). The 51,51% (17; 33) presented comorbidities of causes: neurological, pulmonary and genetic among the main ones. Mortality was 18,20% (6; 33) related to the severity of comorbidities, except one secondary to tracheal stenosis. CONCLUSION. Laryn-gomalacia and subglottic stenosis were the predominant pathologies with congenital stridor. The comorbidities that occurred were neurological, pulmonary, genetic and caused mortality within 90 days after diagnosis.
INTRODUCCIÓN. Las anomalías de la vía aérea son poco frecuentes, pero potencialmente mortales. El estridor es un ruido respiratorio con mayor predominio en la fase inspiratoria. OBJETIVO. Evaluar la etiología del estridor, determinar sus comorbilidades y la mortalidad. MATERIALES Y MÉTODOS. Estudio transversal retrospectivo. Población de 110 y muestra de 33 datos de Historias Clínicas de pacientes neonatos o lactantes que presentaron estridor en el Hospital de Especialidades Carlos Andrade Marín de Quito - Ecuador, de enero 2009 a diciembre 2020. RESULTADOS. El 51,51% (17; 33) de casos fueron hombres. La edad de la primera consulta por estridor fue dentro del primer mes en el 18,00% (6; 33) y del 40,00% (13; 33) a los 3 meses. La patología congénita laríngea más frecuente fue: laringomalacia 81,82% (27; 33), seguida de estenosis subglótica 9,09% (3; 33), parálisis cordal bila-teral 6,06% (2; 33) y estenosis traqueal 3,03% (1; 33). El 51,51% (17; 33) presentaron comorbilidades de causas: neurológica, pulmonar y genética entre las principales. La mortalidad fue 18,20% (6; 33) relacionada con la severidad de las comorbilidades, excepto una secundaria a estenosis traqueal. CONCLUSIÓN. La laringomalacia y la estenosis subglótica fueron las patologías que predominaron con estridor congénito. Las comorbilidades que se presentaron fueron neurológica, pulmonar, genética y causaron mortalidad dentro de los 90 días posteriores al diagnóstico.

The current global COVID-19 pandemic is caused by the novel coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Currently, acquired tracheoesophageal fistulas are mainly iatrogenic lesions produced by prolonged tracheal intubation. We present a case of tracheoesophageal fistula with severe tracheal stenosis following tracheal intubation in a patient with SARS-CoV-2 infection.
