Carotid stenting has recently been considered as an alternative treatment to carotid endarterectomy for certain patients with carotid stenosis. Hence, performing carotid arteriography with minimal morbidity and mortality is essential. The purpose of this study was to audit complications of diagnostic carotid/cerebral arteriography performed by a vascular surgeon with experience in endovascular interventions. One hundred one consecutive patients underwent 4-vessel arch aortography with selective carotid, subclavian, and/or vertebral arteriography with use of the Seldinger technique. Demographic data, indications, procedure approach (transfemoral, brachial), number of arteries punctured, type of selective injection, contrast volume, and procedure time were analyzed. Minor complications were those that do not significantly alter the health or activity of the patient or require extra hospitalization or treatment. Other complications were defined as major complications. The technical success rate was 99% (100/101 patients). These included the following: 82 patients with right carotid artery, 82 with left carotid artery, 15 with right subclavian artery, 21 with left subclavian artery, 11 with right vertebral artery, and 17 with left vertebral artery (a total of 228 selective injections). Indications for procedures included the following; transient ischemic attack (TIA)/stroke symptoms in 66%, asymptomatic carotid stenosis in 22%, upper limb claudication in 4%, and vertebrobasilar insufficiency in 4%. Right femoral puncture was used in 79%, left femoral in 12%, and left brachial in 9%. The mean amount of contrast used was 101 cc (45–250 cc) and the mean procedure time was 46 minutes (22–132 minutes). There were 5 complications in the whole series; 3 major complications (3%), including 1 minor stroke (1%) with carotid injection, 1 TIA, and 1 major retroperitoneal bleeding; and 2 (2%) minor complications. The major complication rate in this series compares favorably to published rates of 5.7% to 9.1%. There was no association between complications and specific risk factors except for a longer catheterization time (66 minutes versus 45 minutes, p = 0.011). Carotid/cerebral arteriography can be done safely by experienced vascular surgeons with minimal perioperative complications that compare favorably with what has been reported in the radiology literature.
