Simultaneous stenting of the carotid artery and other coronary or extracoronary arteries: Does a combined procedure increase the risk of interventional therapy?

Simultaneous interventions in carotid and other extracarotid arteries are not performed on a routine basis up to now. In 67 out of 295 consecutive patients (23%) undergoing elective stenting of the internal carotid artery, additional interventions in the coronary arteries (n = 65), the iliac artery (n = 3), renal artery (n = 1), left subclavian artery (n = 3), vertebral artery (n = 4), or a combination thereof were performed. Primary stenting was done in 51 (74%) out of 69 carotid arteries, in 48 (74%) of 65 coronary arteries, and in 10 (91%) of 11 other targeted vessels. Neurological complications consisted of two (2.9%) transient ischemic attacks and one (1.5%) minor stroke. In addition, one (1.5%) myocardial infarction occurred during coronary artery intervention. In comparison, 16 (6.6%) transient ischemic attacks, 1 minor stroke (0.4%), 5 (2.2%) major strokes, and 3 (1.2%) deaths were observed in 228 patients without combined procedures. Simultaneous percutaneous interventions including carotid arteries and other extracarotid arteries are feasible, relatively safe, and cost‐effective.Catheter Cardiovasc Interv 2003;60:314–319. © 2003 Wiley‐Liss, Inc.
