“…The existence and extent of tracheal narrowing can often be detected by P-A chest radiography or lateral thoracic inlet radiography [3,4]. Although axial CT images in the patient presented here showed a saber-sheath type tracheal narrowing, preoperative P-A chest radiograph did not clearly reveal this condition.…”

We report here a 59-year-old man with a saber-sheath tracheal narrowing who was scheduled to undergo pharyngeal tumor resection under general anesthesia. The tracheal narrowing was not clearly detected by chest radiography during the preoperative examination, but it was visible on axial computed tomography (CT) images taken earlier for diagnostic purposes. Following fiber optic examination of the narrowed segment with the patient under anesthesia, the tube was inserted into the trachea using an Airway Scope. The tube was deliberately advanced into the trachea and was able to pass through the stenosis without any resistance. On postoperative radiological analysis, three-dimensional reconstruction of the trachea and virtual bronchoscopic images revealed a saber-sheath type tracheomalacia located from below the cricoid cartilage to the carina. The membranous wall had a normal width. This case indicates that chest radiographs may occasionally be inadequate for evaluating asymptomatic patients with tracheomalacia. If CT images have been taken for diagnostic purposes, they should be examined together with the chest radiograph. Digital chest radiography with edge enhancement may become a useful tool in the preoperative detection and evaluation of undetectable tracheal narrowing on conventional chest films.

“…[9][10][11] In addition, the discontinuation of amiodarone can be associated with a paradoxical worsening of thyrotoxicosis. In certain patients, treatment with amiodarone cannot be discontinued because of the severity of their cardiac rhythm disorder, especially in the case of complex ventricular arrhythmias.…”

“…15 Finally, as a result of the pharmacodynamic modifications caused by thyrotoxicosis, propofol doses must be increased to obtain effective anaesthetic concentrations. 9 As far as thyroidectomy is concerned, the distinction between type I and type II amiodarone-associated thyrotoxicosis makes no difference for the surgeon. There are no distinguishing features, unless the procedure is performed in extreme emergency (as in our cases 10 and 11).…”

“…Severe, symptomatic hypothyroidism can cause myxedema coma, pericardial effusion, and heart failure. [6,7] Perioperatively, hypothyroid patients are prone to drug-induced respiratory depression and aspiration due to delayed gastric-emptying. Blunted baroreceptor reflexes and decreased intravascular volume can lead to severe h y p o t e n s i o n .…”

Bicuspid aortic valve is the most common birth defect affecting the heart and is present in 1-2% of the population. The abnormal valve structure leads to turbulent flow, fibrosis, calcification, and aortic stenosis. Aortic stenosis increases perioperative morbidity and mortality. Anesthetic techniques that reduce systemic vascular resistance (regional neuraxial techniques) must be used with extreme caution. Hashimoto's disease or chronic thyroiditis or autoimmune thyroiditis is the most common cause of hypothyroidism in adults. Regional anesthesia is preferred in patients with hypothyroidism as recovery from general anesthesia may be delayed by hypothermia, respiratory depression, or slow drug biotransformation. This is a case report of anesthetic management of a middle-aged female with co-existing aortic stenosis, hypothyroidism, and fibroid uterus posted for abdominal hysterectomy.
