Arteriographic complications in the DSA era.

Prospective data were collected on complications associated with intraarterial digital subtraction angiography in 2,475 consecutive patients at a 650-bed Melbourne teaching hospital. Carotid or cerebral studies were performed in 939 patients, and the prevalence of stroke (ie, permanent neurologic deficit) was 0.3%. The overall prevalence of systemic complications was 1.8%, with no patients requiring hemodialysis because of renal failure. Comparison was made with previously reported complication rates for conventional film angiography.
