Acute coronary artery occlusion likely due to thrombus occurring during coronary angiography: report of a case

Abstract

Twenty-five years ago, fatalities due to acute thrombotic coronary occlusion occurring during coronary angiography were reported not infrequently, but are thought to have been eliminated by changes in technique and equipment. We present a case with documentation of a normal coronary arterial tree just before the time of an abrupt occlusion, which had the angiographic features of clot. The likely source of the thrombus was the arterial sheath. Measures for prevention of this complication are discussed.
