Scimitar syndrome: cine magnetic resonance imaging demonstration of anomalous pulmonary venous drainage.
A "scimitar" shadow was found on routine chest roentgenography in an asymptomatic patient. Evaluation with cine magnetic resonance imaging demonstrated an anomalous pulmonary vein draining into the inferior vena cava below the diaphragm. The diagnosis of scimitar syndrome was confirmed and successfully repaired at operation. Cine magnetic resonance imaging may be of considerable value in the assessment of congenital pulmonary venous abnormalities and may provide an alternative to more traditional invasive diagnostic techniques in certain circumstances.

Minitracheostomy is a technique to assist in the removal of airway secretions while maintaining glottic function. A flanged, reclosable cannula 4.0 mm in internal diameter is inserted through the cricothyroid membrane into the trachea. Sixty procedures were performed in 56 patients from July 1988 to June 1989. ⋯ No adverse laryngeal effects were seen. A successful result, not requiring other invasive methods to remove secretions, was obtained in 43 (72%) of the 60 procedures. Minitracheostomy is a useful adjunct for secretion removal in the hospitalized patient.

Progressive left chest volume loss developed in a patient with severe flail chest despite reasonable oxygenation without intubation. Because of this chest volume loss, pain, and shortness of breath, she underwent open chest wall repair using multiple metallic struts. Rapid recovery ensued, despite a perforated duodenal ulcer on postoperative day 1. Benefits of open fixation of severe flail chest are clearly demonstrated and should be considered instead of prolonged ventilation or supportive care alone for select patients.

Unilateral lung transplantation has become a successful method for the treatment of end-stage pulmonary disease, whereas double-lung transplantation has provided benefit to patients with nonfibrotic lung disease such as emphysema and cystic fibrosis. In the past 5 years, 16 single-lung and 13 double-lung transplantations have been performed by the Toronto Lung Transplant Group in patients with end-stage lung disease. Seven perioperative and two late deaths have been recorded so far. ⋯ Most of the techniques proposed against ischemia can be classified as normothermic or static hypothermic cardiopulmonary preservation. The use of the normothermic method has not always been successful. For this reason, interest has now been directed toward the potential for hypothermic preservation of the heart-lung bloc and the use of free-radical scavenger therapy in the reduction of reperfusion injury.
