An Unusual Case of Tracheoesophageal Fistulae

Acquired tracheoesophageal fistulae (TEF) are commonly due to malignancy (M. F. Reed and D. J. Mathisen, 2003). We present the case of a patient with a deceptive history for TEF and report an approach that provides adequate oxygenation, ventilation, surgical exposure, and postoperative analgesia with excellent outcome

Magnets and implantable cardioverter defibrillators: What′s the problem?

A growing number of surgical patients present to the operating room with implantable cardioverter defibrillators (ICD). Peri-operative care of these patients dictates that ICD function be suspended for many surgical procedures to avoid inappropriate, and possibly harmful, ICD therapy triggered by electromagnetic interference (EMI). An alternative to reprogramming the ICD is the use of a magnet to temporarily suspend its function. However, this approach is not without complications. We report a case where magnet use failed to inhibit ICD sensing of EMI, and a shock was delivered to the patient. Measures to decrease EMI, controversies regarding magnet use, and expert recommendations are discussed

Intravenous thrombolytic therapy for patients with ventricular assist device thrombosis: An attempt to avoid reoperation

A growing number of patients are undergoing prolonged management of advanced heart failure with the use of continuous flow left ventricular assist devices (LVADs). Subsequently, an increasing number of patients are presenting with complications associated with these devices. Based on an analysis of three major LVAD institutions, the number of patients developing LVAD pump thrombosis may be much higher than originally projected.[ 1 2 ] The management of this highly feared complication continues to be challenging, as the population of LVAD patients is very heterogeneous and heavily burdened with comorbidities. The standard protocol of increasing anticoagulation may fail to achieve successful resolution of thrombus. Difficulty and poor prognosis may make reoperation less than desirable. Here, we present a case of successful thrombolysis following intravenous administration of tissue plasminogen activator in the Intensive Care Unit setting

Incidental finding of a left atrial thrombus during surgical management of a massive pulmonary embolism

A 58-year-old male presented with a hemodynamically significant pulmonary embolism. Computed tomography angiogram revealed a saddle embolus in the main pulmonary artery with extensive clot burden affecting all lobes and right heart strain. Transthoracic echocardiogram displayed a dilated right ventricle with reduced systolic function. The patient was scheduled for pulmonary embolectomy. The intraoperative transesophageal echocardiogram (TEE) demonstrated a mobile left atrial thrombus that was missed on previous imaging. After removal of the thrombi, TEE showed a patent foramen ovale (PFO). The left atrial thrombus passed across the PFO secondary to increased right heart and pulmonary pressures

Diabetes mellitus in anaesthesia

Anaesthesiologists frequently encounter patients with diseases of the endocrine system, in particular diabetes mellitus. The major risk factors for people with diabetes undergoing surgery are the associated end-organ diseases: cardiovascular autonomic neuropathy, joint collagen tissue, and immune deficiency. Due to the fact that endocrine diseases can be associated with significant peri-operative morbidity and mortality, it is critical that anaesthesiologists understand these disorders and when indicated request the appropriate investigations. </jats:p
