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

The outcome differences between Chinese male and female patients within one-year follow-up after percutaneous coronary intervention(PCI) with stent remain unclear.The present study was aimed to compare clinical outcomes in such two populations.From May 1999 to December 2009,4,334 patients with acute myocardial infarction(MI),unstable angina,stable angina,or silent ischemia,who underwent PCI,were registered at our centers.Among these,3,089 were men and 1,245 were women.We compared these groups with respect to the primary outcomes of MI and secondary outcomes including a composite of major adverse cardiac events(MACE) including cardiac death,MI,target lesion revascularization,target vessel revascularization(TVR),stent thrombosis(ST),definite ST and probable ST at one-year follow-up.Chinese male patients had a higher MACE rate(13%vs.10.7%,P =0.039),mainly led by TVR(9.09%vs.6.98%,P=0.024) at one year,which was significantly different than female patients.Chinese male and female patients showed a significant difference on MACEs.However,there was no significant difference with respect to MI between these groups. 展开更多

ObjectiveTo evaluate the long-term efficacy of covered stent implantation in the treatment of elderly patients with coronary perforation while undergoing percutaneous coronary intervention (PCI).MethodsFrom June 2004 to June 2012, our center has followed ten elderly patients (age≥ 60 years) who sustained coronary perforation during PCI. The major adverse cardiac events (MACE) were observed as well. The patients were advised to take 75 mg/day Clopidogrel for two years, and indefinite use of 100 mg/day enteric-coated aspirin.ResultsSix out of the 10 patients aged from 60 to 76 years old (mean 68.6 ± 5.2 years) were male, four were female. The average diameter of the implanted stents was 3.3 ± 0.3 mm, and the average length was 22.1 ± 3.7 mm. All the ruptures were successfully sealed without intra-procedural death. The follow-up duration ranged from 0.6 to 67 months (mean 31.7 ± 24.5 months). One patient died of multiple organ failure due to lung infection in 19 days after PCI; one died of cardiac sudden death in 13 months after PCI; one had angina pectoris in 53 months after PCI; one underwent multi-slice CT examination in six months after PCI, and no in-stent restenosis was found. The other four patients received angiography follow-up, and the results showed that three patients had no intra-stent restenosis, while one had left anterior descending (LAD) restenosis in the covered stent in 67 months after PCI. The in-hospital mortality was 10% (1/10). The MACE rate in 12 months after PCI was 10% (1/10). During the entire followed-up period, the restenosis rate in target vessels was 20% (1/5), mortality was 20% (2/10), and the MACE rate was 40% (4/10).ConclusionTreatment of coronary perforation by using covered stents can achieve favorable long-term results; a two-year dual antiplatelet therapy (DAPT) after PCI can effectively prevent intra-stent thrombosis. 展开更多

Objective To evaluate the method of palliative drainage by means of metallic indwelling stents or plastic tubes for patients with malignant biliary obstruction.Methods From January 1995 to Febuary 2001, 243 consecutive patients (161 men and 82 women; aged 26-91 years, mean of 61.3 years) with malignant biliary obstruction were treated with transhepatic placement of metallic stents and/or plastic tubes. Among them, 47 patients had pancreatic carcinoma, 98 cholangiocarcinoma, 28 metastatic carcinoma and 60 hepatic carcinoma. 169 stents of nine types were used in this series. After stenting, 47 patients were treated for local tumors. Procedure- and device-related complications were recorded. Patient survival and stent patency rates were calculated with Kaplan-Meier survival analysis.Results One hundred and three patients underwent successfully stent placement for the first time. Others had their stents installed 1 - 2 weeks after catheterization. Stents were used in 132 patients. Ninety-five patients were treated with a single stent. Seventeen patients had two stents installed for bilateral drainage, 20 patients had two stents installed from top to bottom to create stenting of adequate length, and 12 patients had stents placed across the ampulla. The 2-month mortality rate was 8. 64% (21/243). Major complications occurred in two patients (0.8%, 2/243). Minor complications included self-limited bleeding into the drainage tubes and fever. The average patency of the initial stent was 7. 5 months and average survival was 9 months. Thirteen patients received brachytherapy in their stents, 15 extra radiation therapy, and 19 intra-arterial infusion chemotherapy. The 47 patients treated for local tumors had an average survival of 11. 3 months (log rank 32.8, P < 0.001) with an average patency of 9. 7 months(log rank 4. 7, P<0. 05).Conclusion Percutaneous transhepatic bile drainage as a palliative procedure is well tolerated by patients. After stenting, treatment for local tumor may prolong the duration of stent patency and the survival of patients. 展开更多

Background The sirolimus and paclitaxel distribution patterns and tissue residence time may be modified in atherosclerotic lesions for patients with diabetes, and the biological mechanisms of action for these agents differ significantly. Previous clinical trials have yielded discrepant results of major adverse cardiac events and restenosis between a sirolimus-eluting stent and a paclitaxel-eluting stent in coronary artery disease. Therefore, this study was conduced to compare in-hospital and long-term clinical outcomes between patients receiving sirolimus-eluting stent (Cypher or Cypher Select stent) and paclitaxel-eluting stent (Taxus Express stent) after percutaneous intervention (PCI) in Chinese patients with diabetes. Methods One hundred and sixty-four consecutive diabetic patients underwent PCI in Fuwai Hospital from April 2004 to December 2004. Of them, 101 patients received Cypher or Cypher Select stents (Cypher group, 145 stents) and 63 patients received Taxus Express stents (Taxus group, 129 stents). Repeat coronary angiography was performed at 6-month and clinical outcomes were evaluated at 1- and 3-year follow-up. Stent thrombosis was classified according to Academic Research Consortium (ARC). Results The two groups did not differ significantly with respect to cardiac death, recurrent myocardial infarction (re-MI), target vessel revascularization (TVR) and occurrence of major adverse cardiac events (MACE). And the MACE-free cumulative survival at 1- and 3-year follow-up and early, late and very late thrombosis rates were also similar in the two groups (all P〉0.05). There was a trend favoring PES over SES with regard to reducing cardiac death (0 vs 2.0%, P=-0.524), re-MI (0 vs 2.0%, P=-0.524), the composite of the cardiac death and re-MI (0 vs 4.0%, P=-0.299) and very late thrombosis (0 vs 3.0%, P=-0.295) between 1-year and 3-year follow-up. Conclusion The study indicates that PCI with either Cypher or Taxus stents is associated with similar efficacy and safety in the small population of Chinese diabetic patients during long-term follow-up. 展开更多
