Modified venous catheter technique for digital angiography.
A 5-F dilating catheter that has been modified with side holes is described for venous injection digital angiography. This catheter can be rapidly placed in an antecubital arm vein in most patients without fluoroscopy, even in those patients whose arm veins are inadequate for other techniques. In studies of over 100 carotid arteries that were performed using this method, images of diagnostic quality have regularly been obtained.
