Selective opacification of arteries with balloon-occlusion angiography.
Selective catheterization of vessels for angiography in infants is often difficult. The authors describe the use of a balloon-tipped catheter to direct contrast material to a selected area; consequently, smaller volumes of contrast material are used than is usually required for conventional angiography. The angiograms obtained provide excellent anatomic visualization.
