[Simulated stenosis of the common femoral artery in intravenous digital subtraction angiography by palacos following hip joint endoprosthesis implant--a possible source of error in videodensitometry determination of the degree of stenosis].
Radiation absorbing foreign material in the patient's body, such as palacos, may mimic significant vascular stenoses in DSA. The potential pitfalls of geometric and videodensitometric quantification of stenosis are discussed.
