Routine operative arteriography during carotid endarterectomy: A reassessment

One hundred and thirty-one consecutive operative arteriograms done in conjunction with carotid endarterectomy are reported. Radiographically obtrusive defects were found in 5.3% of arteriograms, with 1.5% in the common carotid artery, 2.3% in the external carotid artery, and 1.5% in the internal carotid artery. Potential complications were introduced by the operative arteriograms in 2.3% of the patients. One patient developed a persistent hemiparesis thought to be related directly to the performance of the arteriogram. On the basis of this review, routine operative arteriography as an adjunct to carotid endarterectomy has been discontinued at out institution. Specific indications for obtaining operative arteriograms are outlined.
