Clinical study demonstrates high diagnostic accuracy for intravenous digital video subtraction angiography in renal vascular disease, highlighting a safe and cost-effective outpatient option.
A digital subtraction system for performing intravenous angiography has been developed and applied to the diagnosis of renal vascular abnormalities. A total of 35 patients underwent 39 intravenous angiographic examinations for a variety of renal-related clinical indications. Satisfactory examinations were achieved in 36 cases (92%) with a high degree of diagnostic accuracy. Digital video subtraction angiography is an outpatient procedure that is accurate, safe, and inexpensive to perform.
