The modified Simmons catheter: experience and complications.
The use of the modified Simmons catheter in a selected group of patients over 60 years old, where difficult catheterization was expected, is described. The ease of reforming the loop of the catheter and the ease with which tortuous brachiocephalic vessels are catheterized leads to the recommendation that this catheter should be used routinely in cerebral angiography where ectasia of the arteries is expected.
