ABSTRACT: Background: Angioplasty and stenting have recently become attractive options for cerebral large artery stenosis in China. However, there are limited data on safety and long-term outcomes in Chinese patients having undergone cerebral interventional procedures. To address this need, we set up a common database - the China Interventional Stroke Registry (CISR) - to describe patient characteristics, interventional images, periprocedural complications and long-term clinical outcomes and to determine how adherence to guideline-based treatments in the 'real world' works in China. Methods: Six medical centers have participated since 2004. They entered into an Internet-based database data on demographics, clinical history and angiography of patients undergoing angioplasty with/without stenting in extracranial arteries (carotid, vertebral and subclavian arteries) and/or intracranial arteries (middle cerebral artery, vertebral artery and basilar artery) in China. CISR is a research-funded project. Results: As of October 2012, we have already collected detailed clinical information on 1,356 patients (age: 63.6 ± 10.2 years, male: 1,084, 79.9%). The overall data quality is good. Site data quality control is supported via detailed monthly feedback reports and quarterly data monitoring meetings. Conclusions: The CISR is the first and the largest registry for angioplasty with/without stents in China. The database will provide the characteristics and outcomes of patients and the situation of adherence to guideline-based treatments under 'real-world' conditions in China.

ABSTRACT: 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.

ABSTRACT: To evaluate the effect of carotid angioplasty and stenting (CAS) on postoperative cerebrovascular reactivity (CVR) and its independent predictors.
During July 2008 and September 2009, 37 patients undergone CAS were enrolled in this study. Breath holding tests using transcranial Doppler were performed for each patient before, 1 to 2 days, and 3 to 10 months after the procedure. CVR was evaluated by the breath holding index (BHI). Repeated measures analysis of variance was employed to detect the BHI changes after CAS. Multivariate linear regression was used to identify the independent predictors for BHI.
A significant improvement of the ipsilateral BHI values was observed after stenting (P < 0.05). The follow-up BHI values were positively correlated with those after procedures (β = 1.030, P < 0.001), while negatively correlated with tandem stenoses (β = -0.016, P = 0.002).
CAS results in an immediate improvement and a gradual normalization of the ipsilateral CVR. Tandem stenoses are an independent predictor for CVR.
