Risks of Outpatient Angiography and Interventional Procedures: A Prospective Study

Abstract

We observed a low incidence of complications requiring further treatment or resulting in a permanent deficit. The rates are comparable to published data from similar studies and practice standards guidelines. A statistically significant improvement was seen in the total complication rate between the periods March 1997-June 1999 and July 1999-March 2002 (p = 0.01).
