Effects of supramaximal balloon dilatation pressures on adult cricoid and tracheal cartilage: A cadaveric study

Tracheal rupture after vocal cord polyp resection: A case report

INTRODUCTION

Transoral laser microsurgery (TLM) is one of the most common operations performed for glottic lesions. Several protection measures are taken to prevent tracheal damage. However, some protection measures and common postoperative complications may still cause delayed tracheal rupture in certain situations. Cases of tracheal rupture after surgery are extremely rare, and there are no previous reports of TLM of the glottis causing tracheal rupture.

PATIENT CONCERNS

A middle-aged woman who underwent TLM for bilateral vocal cord polyps developed sudden neck pain, followed by cough and subcutaneous emphysema.

DIAGNOSIS

She underwent head, neck, and chest computed tomography (CT), which revealed a 4-cm membranous tracheal tear located 4.5 cm distal to the glottis, pneumomediastinum, and subcutaneous emphysema extending from the base of skull to the chest.

INTERVENTIONS

The patient underwent an emergency surgical surgical chest exploration and tracheal repair.

OUTCOMES

One month after the surgery, the patient fully recovered with no tracheal stenosis or respiratory dysfunction.

CONCLUSIONS

Conventional protective measures and common postoperative complications of TLM may also cause tracheal rupture.

Pediatric tracheal trauma

Tracheal trauma is an uncommon but potentially serious cause of airway injury in children. Presentation may be acute in cases of blunt or penetrating trauma, or delayed in cases of chronic irritation or indwelling endotracheal tubes. Symptoms include dyspnea, progressive respiratory distress, neck and chest swelling and ecchymosis, and dysphonia. Workup is pursued as allowed by the patient's clinical status and may include plain radiography, computed tomography, and endoscopy. Accuracy and efficiency of diagnosis is paramount for those at risk of rapid decompensation. Treatment may include observation, elective and strategic intubation, or primary surgical repair.

Transmural rupture and cartilage ring fracture in a tracheobronchial tuberculosis patient

Tuberculosis (TB) tracheobronchial stenosis is considered as the worst complication of tracheobronchial TB (TBTB). Endobronchial balloon dilation (EBD) is a promising treatment for adult tracheal stenosis; however, it may be complicated by transmural rupture and cartilage ring fracture. We present a 29-year-old female with a six-month history of cough and chest pain, and three weeks of dyspnoea. She was diagnosed with TBTB with active caseous lesions and had an effective response to anti-TB treatment. Nevertheless, she suffered recurrent tracheobronchial stenosis requiring several bronchoscopic treatments, including EBD. Her eight-month follow-up bronchoscopy showed transmural rupture and cartilage ring fracture of the anterior trachea. The patient finally recovered after 18 months of conservative management. Transmural rupture and cartilage ring fracture on the anterior trachea wall without pneumomediastinum or subcutaneous emphysema in TBTB patients may be best treated with a conservative approach.

Bronchoscopic balloon dilatation combined with laser cauterization of high and long segmental tracheal stenosis secondary to endobronchial tuberculosis: A case report

Background

Airway stenosis after bronchial tuberculosis may reduce the patient's activities of daily living owing to various respiratory symptoms. Thus, it is necessary to treat the condition. Various treatment modalities, such as balloon dilatation, are attempted in cases where radical surgical resection is difficult to perform; however, the best treatment method remains unknown. Although balloon dilatation is relatively easy to perform and effective, there are not many cases reporting successful treatment of tracheal stenosis as compared to that of bronchial stenosis.

Case presentation

We report a case involving a 63-year-old man who presented with dyspnea on effort and stridor for 6 months. He was diagnosed with bronchotracheal stenosis due to endobronchial tuberculosis. A chest computed tomography scan showed thickening of the tracheal lumen and deformation of the tracheal cartilage from the annular cartilage to the middle trachea, and severe stenosis in the left main bronchus. Good patency of the trachea and the left main bronchus was obtained after two rounds of balloon dilatation with laser cauterization, which resulted in improvement of symptoms over a relatively long period.

Conclusions

Our study shows that balloon dilatation combined with laser cauterization can be easily repeated and may be effective for treatment of patients with bronchotracheal stenosis, wherein radical treatment cannot be performed.
