[Misinterpretations in arteriography of the lower extremities]

Arteriography is still the most important diagnostic tool in the assessment of chronic lower limb ischemia. Unfortunately, demonstration of distal vessels is often poor. Inadequate arteriography makes decisions on the feasibility and the site of reconstruction impossible. Methods to improve the quality of arteriograms include correct positioning of the legs in internal rotation, long exposure times, additional lateral views and the capacity of digital subtraction. The importance of positioning the legs in internal rotation is illustrated by several examples.
