We report the results of our first 2 years of experience with routine carotid angiography with an emphasis on technique and complications. We reviewed the hospital records, office charts, and prospective quality-assurance database records of 336 patients undergoing cerebrovascular arteriograms
and collected data on the indications, complications, and technical aspects of the procedures. Indications for angiography included carotid stenosis in 331 (95%) patients, subclavian steal syndrome in 9 patients, vertebrobasilar insufficiency in 6 patients, and carotid body tumor in 2 patients.
Selective catheterizations were performed on 654 common carotid arteries, 63 subclavian arteries, and 63 vertebral arteries. Both common carotid arteries were not selectively catheterized in 34 (9.8%) patients. Reasons for not selecting one or both common carotid arteries included physician
choice to limit contrast administration in patients with renal insufficiency in 16 cases, proximal occlusion in 4 cases, proximal stenosis thought to be at risk of embolization if instrumented in 3 cases, imaging equipment malfunction in 2 cases, and in only 9 (2.6%) cases was selective carotid
catheterization attempted but unsuccessful. There were no procedure-related deaths. Complications were documented in six (1.8%) patients, including cerebrovascular accident (CVA) in 1 (0.3%) patient. One hundred forty-two (41%) patients went on to carotid endarterectomy, and we performed 16
carotid bifurcation stents during the study period. Routine selective carotid angiography is a low-risk procedure that can be performed safely by vascular surgeons with catheter/guide wire skills.
