[Digital subtraction angiography in percutaneous transluminal angioplasty of vessels of the extremities and renal vessels].

The new imaging method digital subtraction angiography (DSA) permits intravenous arteriography. 1259 patients were thus investigated over one year. The lower extremities comprised 21,4% of assessment areas. 120 investigations in 95 patients were based on an indication of percutaneous transluminal angioplasty (PTA). DSA can be used before and after the PTA. The small extent of invasiveness and the shortening of in-patient admission are particular advantages preoperatively. These advantages, in addition to the possibility of out-patient evaluation, are also true for DSA in comparison to the conventional arteriography. Thus the combination of both methods has been found to be very suitable.
