In this study, we aimed to evaluate the safety and feasibility of simultaneous bilateral carotid artery stenting (BCAS) compared with staged BCAS in patients with bilateral atherosclerotic carotid stenosis (BCS). From January 2004 to March 2012, 68 patients who underwent BCAS were identified from the Nanjing Stroke Registry Program. Of these patients, 42 (61.8 %) underwent simultaneous BCAS (simultaneous group), and 26 (38.2 %) underwent staged BCAS (staged group). We compared demographic data, major vascular risk factors, procedural parameters, and 30 day outcomes between the simultaneous and staged groups. No significant differences were detected in baseline data between the groups. Patients in the simultaneous group had a lower post-operative systolic pressure compared with the staged group (119.1 ± 16.1 vs. 130.2 ± 17.5 mmHg, P = 0.009). Technical success was 100 % of patients in the simultaneous group and 98.1 % in the staged group. Hemodynamic depression was observed in 57.4 % of procedures, with no significant difference between groups in the rate of HD. Four (5.9 %) patients had neurological complications within 30 days, including two cases of hyperperfusion syndrome in the simultaneous group, and two ischemic events in the staged group. There was no significant difference in the 30 day complication rate between the simultaneous and staged groups (4.8 vs. 7.7 %, P = 0.633). Simultaneous BCAS may be safe and feasible for most patients with BCS, with a similar 30 day complication rate to staged BCAS. Multicenter randomized control studies with larger sample sizes are warranted to further explore the safety and efficacy of simultaneous BCAS.
