[Other applications of numeric angiography].

Digital subtraction angiography (DSA) is a valuable technique to study the aorta and its branches by intravenous injection. This technique is particularly devoted to study hypertensive patients and renal transplants. Nevertheless, the intravenous injection presents some limits, so the arterial route is sometimes still necessary. The arterial approach is particularly useful for studying immediate results of the arterial angioplasty.
