BACKGROUND The authors previously showed that propofol attenuates bronchoconstriction. Recently, a newer formulation of propofol with metabisulfite preservative has been introduced. metabisulfite causes airway narrowing in asthmatics. Therefore, we tested whether the preservative metabisulfite abolishes the ability of propofol to attenuate bronchoconstriction. The authors used a sheep model in ...

ZAPATA-ORTIZ, VICENTE, RAMIRO CASTRO DE LA MATA, ENRIQUE FERNANDEZ, ARTURO GEU, AND LUIS BATALLA. Bronchial circulation in high altitudes. Am. J. Physiol. 2 I 2 (6) : I #j41468. 1967. -Bronchial circulation and bronchopulmonary anastomoses have been studied in two groups of sheep native to the high Andes (above 4,000 m) and to the Peruvian coastal plain. The high altitude-adapted animals showed...

A corrosion cast of the bronchial arteries provides a useful method of demonstrating their origin and distribution. A cast of the bronchial tree is made at the same time to show the position of the arteries. The cast produced by the method described here is limited to the principal branches of these arteries, the finer terminal twigs being lost. However, as these terminal twigs follow closely t...

: Anastomotic complications following lung transplantation include those affecting one of the three anastomoses performed in usual technique for transplantation: bronchial, pulmonary artery, and venous anastomoses. Airway have declined over time, but still are associated with significant morbidity mortality. The main pathogenic factor to development airway is post-transplant bronchial ischemia....

The most striking point brought out in this study is that as long as a definite pressure is maintained in either the pulmonary or bronchial circulations, the admixture of bloods is extremely limited. It is easily conceivable that more mixture occurs normally than under the conditions of the experiment, but there is no reason for considering this to be a large difference. If, however, in either ...

Bronchiectasis is characterized by the abnormal and permanent dilatation of bronchi. Clinical manifestations of bronchiectasis include persistent or recurrent cough, purulent sputum, hemosputum, and hemoptysis. A 75-year-old man with bronchiectasis required coronary bypass grafting for unstable angina pectoris with severe stenosis of the left main trunk. Computed tomography showed fistulae betw...

Congenital systemic-to-pulmonary artery fistulas are very rare, with the exception of congenital heart disease and pulmonary sequestration. We describe the first reported case of left internal mammary and bronchial artery to pulmonary artery fistulas associated with bilateral coronary arteries to pulmonary artery fistulas.

A 46-year-old woman presented with a 6-month history of dyspnea and weight loss on a background of previous pneumonectomy for bronchial adenoid cystic carcinoma 14 years beforehand. Several years prior to this presentation, she had developed left vocal cord palsy and a metastatic lesion to the right buttock confirmed at resection. Investigations included CT pulmonary angiography and right heart...
