INTRODUCTION The authors performed videolaryngoscopy during the preoperative anesthesia clinic evaluation of a patient with chronic dyspnea, stridor, and a previous hemilaryngectomy scheduled to undergo a series of orthopedic surgery procedures for an infected knee arthroplasty. The findings proved crucial for determining airway management. CASE PRESENTATION A 68-year-old man presented to the...

PURPOSE Subglottic stenosis can result from endotracheal tube injury. The mechanism by which this occurs, however, is not well understood. The purpose of this study was to examine the role of angiogenesis, hypoxia and ischemia in subglottic mucosal injury following endotracheal intubation. METHODS Six Yorkshire piglets were randomized to either a control group (N=3, ventilated through larynge...

Pancreatic duct stones are found in 22 to 60 per cent of patients with chronic pancreatitis (CP). The stones can lead to obstruction of the outflow of pancreatic secretions causing increased intraductal pressure. 2 The pancreas is relatively noncompliant. Therefore the rise in intraductal pressure can induce tissue hypertension and ischemia. This can be a major factor causing pain in patients w...

In July 1988, the liver and pancreas of a cadaveric donor were transplanted separately into a man with type 1 diabetes with end-stage chronic hepatitis B virus. Two features of the operation may help explain the patient's current status as the longest-lived liver-pancreas recipient. One was enteric drainage of pancreatic exocrine secretions. The other was delivery of the pancreas venous effluen...

OBJECTIVES/HYPOTHESIS Objectives were 1) to review the presentation, natural history, and management of subglottic hemangioma; 2) to assess the affect of five variables (age, gender, degree of subglottic narrowing, location and extent of subglottic hemangioma, and lack or presence of other hemangioma) and the outcome of six different treatment modalities (conservative monitoring, corticosteroid...

Treatment of subglottic hemangiomas lacks a standard treatment algorithm defining the role and proper place for the multiple medical and surgical therapeutic alternatives. Open excision of subglottic hemangiomas represents an emerging operative technique with the advantage of being a single-stage procedure with limited morbidity that, at the same time, avoids the potential complications of long...

INTRODUCTION Infantile subglottic hemangiomas are rare causes of airway obstruction. They begin to proliferate at 1-2 months of age and can cause biphasic stridor with or without respiratory distress. Diagnosis requires direct visualization by direct laryngoscopy and bronchoscopy. Various therapeutic options have been utilized for treatment, including tracheotomy, open surgical excision, laser ...
