Fulltext A case report of airway stenting in tracheal compression secondary to right subclavian artery pseudo-aneurysm

Muhammad Naimmuddin Abdul Azih, Aishah Ibrahim, How, Soon Hin, Kuan, Yeh Chunn

International Medical Journal Malaysia, 2018;17(1):141-144.
MyJurnal

We report a 55-year old lady with the presentation of stridor and type II respiratory failure requiring tracheal intubation. She had right Horner’s syndrome associated with pleural effusion. Her chest radiograph revealed right upper zone lobulated opacities and therefore right Pancoast tumor was the initial diagnosis. However, her CECT thorax revealed a huge right subclavian artery pseudoaneurysm with severe tracheal compression. This rare condition imposed a significant diagnostic as well as therapeutic challenge. Vascular surgery is the definitive treatment but it is associated with high risks. The exact role of rigid bronchoscopy for airway stenting is unknown due to limited evidence available. Indeed, this form of central airway obstruction may benefit from temporary tracheal stenting whilst the surgical repair of the lesion is planned. It may facilitate early weaning and allows less complicated airway control.

PMID: 34080535 DOI: 10.1017/S1047951121002110

BACKGROUND: Vascular compression of the airway often complicates CHD management. This study evaluated the use of CT in determining cardiovascular causes, clinical manifestations, and outcome of tracheobronchial compression among children with CHD.
METHODS: A retrospective review of clinical records of all patients with CT scan evidence of tracheobronchial compression from January 2007 to December 2017 at National Heart Institute. Cardiovascular causes of tracheobronchial compression were divided into three groups; group I: vascular ring/pulmonary artery sling, II: abnormally enlarged or malposition cardiovascular structure due to CHD, III: post-CHD surgery.
RESULTS: Vascular tracheobronchial compression was found in 81 out of 810 (10%) patients who underwent CT scan. Group I lesions were the leading causes of vascular tracheobronchial compression (55.5%), followed by group II (34.6%) and group III (9.9%). The median age of diagnosis in groups I, II, and III were 16.8 months, 3 months, and 15.6 months, respectively. Half of group I patients are manifested with stridor and one-third with recurrent chest infections. Persistent respiratory symptoms, lung atelectasis, or prolonged respiratory support requirement were clues in groups II and III. Higher morbidity and mortality in younger infants with severe obstructive airway symptoms, associated airway abnormalities, and underlying complex cyanotic CHD.
CONCLUSIONS: Vascular ring/pulmonary artery sling and abnormally enlarged or malposition cardiovascular structure were the leading causes of cardiovascular airway compression. A high index of suspicion is needed for early detection due to its non-specific presentation. The outcome often depends on the severity of airway obstruction and complexity of cardiac lesions.

Malaysian Journal of Medicine and Health Sciences, 2015;11(1):85-88.
MyJurnal

Acute epiglottitis though relatively common in pediatric patients as compared to adults, present with almost similar clinical presentations. They include voice change, difficulty or painful swallowing and sometimes with upper airway obstruction. Physical finding of swollen epiglottis is difficult to be obtained owing to the danger of introducing laryngeal mirror into the oropharynx as to avoid contact spasm. The diagnostic thumb sign appearance on lateral neck radiograph is considered pathognomonic of epiglottitis. We report a case of an adult with clinical features and radiological finding of an acute epiglottitis, which did not resolve with antibiotic treatment. Subsequent imaging confirmed the presence of an abscess in the epiglottic mucosa.

The EXIT (Ex utero intrapartum treatment) procedures have been, with a high degree of success, employed to treat a myriad types of fetal airway obstruction most commonly neck masses such as cystic hygroma and lymphangioma with ample plan including prenatal diagnosis by ultrasound scan or MRI. Before the advent of EXIT, formal documentations had been published with descriptions of intubation during intrapartum period and fetal airway protection either during normal or operative delivery. We report a 28-year-old gravida 2 para 1 who was referred to our Maternal Fetal Medicine (MFM) unit at 26 weeks and 3 days gestation with a foetal neck mass. We present a case of an successful EXIT procedure performed in the Lloyd Davies position with the hips abducted and flexed at 15 degrees as is employed during gynecologic laparoscopy surgery minus the Trendelenburg tilt. Both mother and baby are well. The benefits of this position are discussed.

International Medical Journal Malaysia, 2017;16(21):28-28.
MyJurnal

Pierre Robin Sequence (PRS) is a condition consists of set of anomalies, which are
cleft palate, micrognathia and glossoptopsis. Management of patients with PRS addresses two main
problems, namely airway obstruction and feeding difficulties. Airway obstruction may lead to
obstructive sleep apnea (OSA). Treatment modalities for OSA are based on the causes. There are
surgical and non-surgical methods. Non-surgical methods such as diet, medication, oral appliances
and continuous positive airway pressure (CPAP) can only be employed in moderate cases. Surgical
method such as maxillo-mandibular advancement or expansion can be achieved by orthognathic
surgery or distraction osteogenesis. (Copied from article).

Ludwig angina is a submandibular space cellulitis secondary to oral cavity infection. It is strongly associated with difficult intubation due to limitation in the mouth opening. The presentation of Ludwig angina varies according to the severity of the infection. The extreme presentations include upper airway obstruction and respiratory failure. We present a female teenager with right submandibular abscess as the consequence of Ludwig angina, who was planned for incision and drainage. Successful awake fibre optic intubation was performed as a method of induction due to trismus, deferring the need for tracheostomy.

Fulltext Comparison of automatic airway analysis function of Invivo5 and Romexis software

Kamaruddin N, Daud F, Yusof A, Aziz ME, Rajion ZA

PeerJ, 2019;7:e6319.
PMID: 30697493 DOI: 10.7717/peerj.6319

Background: Visualization and calculation of the airway dimensions are important because an increase of airway resistance may lead to life-threatening emergencies. The visualization and calculation of the airway are possible using radiography technique with their advance software. The aim of this study was to compare and to test the reliability of the measurement of the upper airway volume and minimum area using airway analysis function in two software.
Methods: The sample consisted of 11 cone-beam computed tomography (CBCT) scans data, evaluated using the Invivo5 (Anatomage) and Romexis (version 3.8.2.R, Planmeca) software which afford image reconstruction, and airway analysis. The measurements were done twice with one week gap between the two measurements. The measurement obtained was analyzed with t-tests and intraclass correlation coefficient (ICC), with confidence intervals (CI) was set at 95%.
Results: From the analysis, the mean reading of volume and minimum area is not significantly different between Invivo5 and Romexis. Excellent intrarater reliability values were found for the both measurement on both software, with ICC values ranging from 0.940 to 0.998.
Discussion: The results suggested that both software can be used in further studies to investigate upper airway, thereby contributing to the diagnosis of upper airway obstructions.

Spontaneous sublingual hematoma as a complication of severe hypertension: first report of a case

Prepageran N, Raman R, Ismail SM, Rahman ZA

Ear Nose Throat J, 2002 Aug;81(8):576-8.
PMID: 12199178

We describe what we believe is the first reported case of a sublingual hematoma secondary to severe hypertension. The patient, a 77-year-old woman, experienced a spontaneous hematoma of the floor of the mouth, tongue, and sublingual space that eventually caused an airway obstruction. We performed an emergency tracheostomy under local anesthesia and then evacuated the hematoma through an incision along the floor of the mouth. The patient recovered uneventfully.

Fulltext Relationship between symptoms and objective measures of airway obstruction in asthmatic patients

Liam CK, Goh CT, Isahak M, Lim KH, Wong CM

Asian Pac J Allergy Immunol, 2001 Jun;19(2):79-83.
PMID: 11699724

The objective of this study was to determine the relationship between asthma symptoms and the degree of airway obstruction as measured by the forced expiratory volume in one second (FEV1) and peak expiratory flow rate (PEFR) in a group of 64 asthmatic patients with clinically stable disease attending a university-based urban asthma clinic. Asthma symptoms did not correlate with the degree of airway obstruction as measured by prebronchodilator PEFR (total asthma symptom score vs PEFR: r = -0.214, p = 0.104, n = 59) and only correlated poorly with prebronchodilator FEV1 (total asthma symptom score vs FEV1: r = -0.256, p = 0.041, n = 64). These results lend support to the recommendation that airway obstruction should be measured objectively when assessing patients with chronic persistent asthma.

Fulltext Metastatic melanoma: a rare cause of central airway obstruction

Abdul Hamid MF, Ban Yu-Lin A, Hassan TM, Mohammad N

BMJ Case Rep, 2017 Nov 04;2017.
PMID: 29103009 DOI: 10.1136/bcr-2017-221545

A middle-aged woman with recurrent malignant melanoma presented initially with massive left pleural effusion. There was a complete obliteration of the left main bronchus on flexible bronchoscopy caused by a mass. Serial cryo-debulking of the tumour was done under rigid bronchoscopy; however, the outcome was not favourable due to the aggressive tumour growth. Vemurafenib was planned after thoracic radiation. She was not keen for the biologics treatment due to financial constraints. We report a case of central airway obstruction due to recurrent aggressive melanoma. More evaluations are needed on the role of interventional pulmonologist for bronchoscopic debulking of this rapidly growing tumour as well as the role of biological agents in treating such cases.

The use of modified VBM laryngeal tube compared to Laryngeal Mask Airway during spontaneous ventilation

Chiu CL, Murugasu J, Chan L

Anaesth Intensive Care, 2003 Apr;31(2):187-92.
PMID: 12712784

We have compared the use of the laryngeal mask airway with the new modified laryngeal tube in a prospective randomized controlled study. Sixty ASA 1 or 2 patients, aged 18 to 65 years, scheduled for elective surgery and breathing spontaneously under general anaesthesia, were studied. After preoxygenation, anaesthesia was induced with fentanyl and propofol. The patients were randomized to receive either a laryngeal mask airway or a laryngeal tube. Anaesthesia was maintained with nitrous oxide, oxygen and isoflurane. We recorded the speed and the ease of insertion, the number of attempts needed to successfully secure the airway and intraoperative complications, such as partial airway obstruction needing airway manipulation. The airway devices were removed with the patients fully awake at the end of surgery. Systolic arterial blood pressure, heart rate and end-tidal CO2 were recorded at various time intervals. Postoperative complications were recorded. We found that the incidence of partial airway obstruction needing intraoperative airway manipulation was higher with the laryngeal tube than with the laryngeal mask airway. We conclude that during spontaneous ventilation the modified laryngeal tube is not as reliable in providing a satisfactory airway and we consider it is not a suitable alternative to the laryngeal mask airway.

Fulltext A Five-Year Review on Pediatric Foreign Body Aspiration

Nasir ZM, Subha ST

Int Arch Otorhinolaryngol, 2021 Apr;25(2):e193-e199.
PMID: 33968219 DOI: 10.1055/s-0040-1709739

Introduction Foreign body aspiration is a leading cause of accidental death in children. Clinical presentation varies from non-specific respiratory symptoms to respiratory failure making diagnosis challenging. Objective To review pediatric patients who underwent bronchoscopy due to suspicion of foreign body aspiration at a tertiary center in Malaysia. Methods We retrospectively studied patients < 11 years old who underwent bronchoscopy from 2008 to 2018. Results Over the 10-year period, 20 patients underwent bronchoscopy, and 16 were found to have foreign body aspiration with equal gender distribution. The most common age group was < 3 years old (75%). The most common clinical presentations were choking (82%) and stridor (31%). Foreign bodies were removed using flexible bronchoscope in 8 cases (50%), and difficulties were encountered in 6 cases (75%). Rigid ventilating bronchoscope was used in 8 cases (50%) with no difficulty. The most common object found was peanut (19%). The majority of foreign bodies were lodged in the right bronchus (43%). Eight patients (80%) received delayed treatment due to delayed diagnosis. The length of hospital stay was longer in the younger age groups. Conclusion Clinical presentation and chest radiograph findings were comparable across all age groups. The most difficulties encountered during foreign body removal were via flexible bronchoscope, in children < 3 years old. There was no significant correlation between age and type of foreign body aspiration. The majority of patients who received delayed treatment were < 3 years old. The length of hospital stay was longer in the younger age groups.

Prevalence of dysphagia is one of the important epidemiological data which will contribute to the proper planning and support the setting up of a swallowing rehabilitation clinic at this hospital. The present study aimed to determine the prevalence of dysphagia in patients with head and neck cancer (HNC) at Hospital Universiti Sains Malaysia (Hospital USM) from 2001-2010. In this institutional retrospective study, a total of 66 records were obtained comprising of 86.4% Malay patients, 9.1% Chinese, 1.5% Indians, and 3% other ethnic groups. These data were taken from the database of HNC patients seen at the dental clinic, Hospital USM between 2001 and 2010. Difficulty swallowing, frequent coughing during meal, choking, diet modification, and non-oral nutritional support were identified as signs and symptoms associated with dysphagia. Results showed that 59.1% of patients have had dysphagia before, during, or after the treatment of HNC. Data from the present study would be instrumental in increasing awareness among clinicians involved in patient care and it may help in planning the outline of management of dysphagia. Furthermore, it is anticipated to have implications for further research in swallowing and dysphagia.

Fulltext Stridor Secondary to Acquired Subglottic Cyst: Rarity Makes it Missed

See GB, Mesran I

Indian J Otolaryngol Head Neck Surg, 2019 Oct;71(Suppl 1):45-48.
PMID: 31741928 DOI: 10.1007/s12070-016-0992-2

Subglottic cysts (SGCs) are a rare cause of airway obstruction in children. Medical advances, higher survival rates for preterm infants, and improved diagnostic equipment have increased the number of reported cases of SGCs over the last three decades, the majority occurring in infants who had been extremely premature neonates and had suffered from respiratory distress, therefore having been intubated and managed in neonatal ICUs. Symptoms of laryngeal cysts depend on the size and the location of the cyst and include a change in the tone of voice, dysphonia, hoarseness, dysphagia, stridor, and dyspnea. This condition is often misdiagnosed as laryngomalacia, asthma, croup, or other diseases, due to the fact that it manifests as recurring respiratory infections, stridor, and wheezing. Death can occur in severe cases that are not treated. When present, it may account for severe inspiratory stridor that compromise the airway. The accepted gold standard treatment is direct laryngoscopy with marsupialization of the cyst to prevent recurrence. Two cases of subglottic cyst in our centre are described here. Although all cases presented differently, but in both of our cases, which have previous history of intubation with prematurity were initially diagnosed as laryngomalacia and croup.
