A severe complication of pulmonary vein angiography.
A pulmonary vein angiogram was performed using a pressure injection with the tip of an end and side hole catheter in a near-wedge position; extravasation of contrast material into a bronchus occurred, causing severe bronchoconstriction. It may be possible to avoid this complication by the use of an end hole balloon catheter in the wedge position, slow flow rates of contrast material, and low pr...

There was a positive correlation between pulmonary arteriolar resistance and the difference in pressure between pulmonary artery and ...
متن کاملAn evaluation of wedge pressures in dogs under conditions of normal and elevated pulmonary vascular pressures.
Fifty-six combined right and left heart catheterizations in normal dogs and clogs with experimental mitral stenosis failed to show a significant positive correlation between pulmonary artery wedge pressure and pulmonary vein pressure when the latter was below approximately 17 mm. Hg. Evidence is presented which suggests that the wedged catheter outlets are totally occluded in many instances in ...
