Transluminal angioplasty: late results sustained by digital intravenous subtraction angiography

Digital intravenous subtraction angiography (DIVSA) appears to be a technique of minimal invasiveness and high accuracy in the follow-up of patients after percutaneous angioplasty (PTA) allowing correct angiographic evaluation in more than 96% of the cases. Correlation between clinical and angiographic findings seems to be excellent. Of the controlled intravenous examinations performed in 54 successful PTA procedures 75% appeared patent after 10 to 30 months, constituting 52% of the original attempts.
