We sought to compare the efficacy of two types of stents in CAS. The data of 212 patients treated with CAS（42 and 170 cases implanted with closed and open loop stents, respectively） for carotid bifurcation stenosis and distal filtration protection devices were retrospectively analyzed. Between closed and open loop stents, there were no significant differences in hospitalization duration, NIHSS score before and after the treatment, stenosis at 12 th month, and cumulative incidence of primary endpoint events within 30 days or from the 31 st day to the 12 th month; while there were significant differences in hemodynamic changes and rate of difficulty in recycling distal filtration protection devices. Use of open vs. closed loop stents for carotid bifurcation stenosis seems to be associated with similar incidence of complications, except for greater rate of hemodynamic changes and lower rate of difficulty in recycling the distal filtration protection devices.展开更多

In this study, we retrospectively analyzed our experience in using EVR to treat benign CVO in 10 patients between April 2005 and September 2010. Methods The mean age of the patients was 65.3 years, 2/10 cases were female, and the origin of cause of CVO in 7/10 cases was the hemodialysis access in the upper extremity. The patients were treated with primary stent placement and evaluated with immediate technical success rate and post-interventional patency rate after the procedure. Results Eight patients were treated successfully with stent placement and experienced symptomatic relief immediately. No technical complications were observed during EVR treatment. Patients were followed up by ultrasonography and venography. Median follow-up was 13 months. Three patients required secondary procedures to maintain patency. Conclusions EVR is an effective and safe treatment in patients with benign CVO. It provides immediate symptom relief and maintains a continuous access for hemodialysis.展开更多
