[Digital subtraction angiography for the follow-up control of percutaneous transluminal angioplasty using a scoring system].

Seventy-two patients were examined by venous DSA following angioplasty, 28 of these within three weeks and 44 six months to three years after the procedure. The resolution of the DVI 2 V is adequate for showing reparative changes after dissection in the short-term follow-up. Demonstration was sufficient to enable one to use a coding system which classified the type and severity of the vascular changes. Clinical and angiographic follow-up showed good agreement regarding the amount of improvement obtained; in these patients, clinical follow-up alone is adequate. Where there has been no change in the clinical state or if there has been deterioration, a DSA examination should be carried out in order to ascertain the reason for the lack of improvement.
