Methods: In this prospective, non-randomized observational study we identified patients who had undergone either stand-alone XEN<sup>®</sup> implantation (XEN solo) or XEN<sup>®</sup> implantation in combination with phacoemulsification (XEN combi). All patients who had undergone an implantation during the period 01.04.17-31.10.19 at the Department of Ophthalmology, Drammen Hospital, Norway, were asked to participate. Success was defined as IOP between 5 - 18 mmHg and 20% pressure reduction without medications. Qualified success required the same pressure interval and reduction but allowed medications. The procedure was deemed as failure if pressure requirements were not met, vision was reduced to light perception or worse, or if there was a converion to secondary glaucoma surgery. Results: Out of 115 patients and 133 eyes identified, 87 patients and 99 eyes consented to participate. All patients were Caucasians with a mean age of 73.6 years. The study had a mean (range) follow-up of 38.9 (28 - 54) months. The mean medicated baseline (SD) was reduced from 22.6 (7.9) mmHg on 3.2 (1.1) medications to 14.2 (5.6) mmHg on 1.4 (1.6) medications. Success and qualified success were achieved in 22.2% and 21.2%, respectively. Needling was performed in 34 eyes. Conclusion: XEN<sup>®</sup> 45 gel stent implantation is a safe procedure, offering a significantly lower IOP and number of medications in a subset of patients with open angle glaucoma.展开更多

This study determined the long-term effect of moderate renal insufficiency on death and major adverse cardiac events （MACE） after stent based PCI and examined whether drug-eluting stent implantation could favourably influence clinical outcome. Methods Major adverse cardiac events and causes of mortality were determined for 1012 patients undergoing percutaneous intervention from January 1, 2002 to December 31, 2004 at Shanghai Ruijin Hospital. Based on estimated creatinine clearance levels, long term outcomes were compared between patients with estimated creatinine clearance 〈60 ml/min （renal insufficiency group; n=410） and those with estimated creatinine clearance ≥60 ml/min （control group; n=602）. Subgroup analysis was also made for patients with renal insufficiency between drug eluting stent （n=264） and bare metal stent implantation （n=146） during PCI. Results During follow-up （average 17 months） after successful PCI, all causes of death （7.1% vs 2.3%, P〈0.01） and cardiac death （3.4% vs 1.0%, all P〈0.01） were significantly higher in renal insufficiency group than in control group. For patients with moderate renal insufficiency, drug-eluting stent implantation reduced significantly all causes of death （5.3% vs 10.9%, P〈0.05） and occurrence of major cardiac adverse events （15.1% vs 24.6%, P〈0.05） compared with bare metal stents. Conclusions Moderate renal insufficiency is an important clinical factor influencing the mortality after PCI in patients with coronary artery disease and the use of drug-eluting stents should be the preferred therapy for the improvement of long-term outcomes in such patients.展开更多

The long-term safety and efficacy of percutaneous coronary stenting in patients aged over 85 years with acute coronary syndrome （ACS） remain unclear. Moreover it is unknown whether there are differences between bare metal stent （BMS） and drug eluting stent iDES） in this special population. Methods A total of 80 patients with ACS aged over 85 years undergoing stenting （BMS group n=21 vs DES group n=59） were retrospectively studied. In-hospital, one year and overall clinical follow-up （12-36 months） of major adverse cardiac events （MACEs） including cardiac deaths, myocardial infarction, target lesion revascutarization （TLR） and target vessel revascularization （TVR） as well as stroke and other major bleeding were compared between the two groups. Results In the entire cohort, the procedure success rate was 93.8% with TIMI-3 coronary flow post-PCI in 93.8% of the vessels and the procedure related complication was 17.5%. The incidence of in-hospital MACEs in BMS group was higher （14.3% vs 6.8%, P=0.30）. The 1-year incidence of MACEs in DES group was 7.0% while there was no MACE in the BMS group. Clinical follow-up for 12-36 months showed that the overall survival free from MACE was 82.9% and the incidence of MACE in the BMS group was lower （5.3% vs 21.1%, P=0.20）. Multivariate regression analysis showed that the creatinine level （OR：. 1.013; 95%CI： 1.006-1.020; P=0.004） and hypertension （OR; 3.201; 95%CI： 1.000-10.663; P=0.04） are two major factors affecting the long-term MACE. Conclusions Percutaneous coronary stenting in patients aged over 85 years is safe and provides good short and tona-term efficacy. Patients with renal dvsfunction and hvoertension may have a relatively hiah incidence of MACE.展开更多

However, less is known about the long-term benefits of stent use in this population. This study was aimed to determine the impact of coronary stenting on extended （5 years） long-term outcomes of patients with chronic renal insufficiency. Methods The study included 602 consecutive patients who underwent successful percutaneous coronary intervention with stenting. Renal insufficiency was defined as an estimated glomerular filtration rate 〈60 rrd.min-1-｜.73 m-2. The major adverse cardiac events were compared for patients with （n=160） and without （n=442） renal insufficiency. Results After the third year of follow-up, nonfatal myocardial infarction and revascularization rates were significantly increased in patients with renal insufficiency compared with those without renal dysfunction （16.9% vs 7.7%, P=0.001; 29.4% vs 15.8%, P 〈0.001）. In patients who had recurrent cardiovascular events, a significantly higher rate of de novo stenosis revascularization was found in patients with renal insufficiency than without renal insufficiency （57.7% vs 22.7%, P 〈0.001）, while there was no significant difference in target lesion revascularization between the groups （51.9% vs 43.6%, P=0.323）. Multivariate analysis demonstrated an independent impact of the presence of renal insufficiency on the major adverse cardiac events （hazard ratio： 1.488, 95% confidence interval： 1.051-2.106, P=0.025） and de novo stenosis （hazard ratio： 5.505, 95% confidence interval： 2.151-14.090, P 〈0.001）. Conclusions The late major adverse cardiac events, after successful coronary stenting, is increased in patients with an estimated glomerular filtration rate 〈60 ml.min-1.1.73m-2. This might be associated with increased risk of de novo stenosis in this population. Chin Med J 2009; 122（2）： 158-164展开更多

Meanwhile, the long-term outcomes of RBES remain unclear. The aim of this study was to develop and validate a model to determine the progression of RBES in patients with benign esophageal strictures. And we also explored the long-term outcomes and safety in patients with RBES. AIM To develop and validate a model to determine the progression of RBES in patients with benign esophageal strictures, based on the demographic data and endoscopic findings. METHODS A total of 507 benign esophageal stricture patients treated by dilation alone or in combination with stenting were retrospectively enrolled between January 2009 and February 2018. The primary outcome was to establish a risk-scoring model predicting RBES in benign esophageal strictures. The secondary outcome was to explore the clinical effectiveness and adverse events in patients with RBES. RESULTS In the study, age, etiology, and number and length of strictures were the independent risk factors for the refractory performance of benign esophageal strictures. According to risk factors of benign esophageal strictures, a risk-scoring model for predicting RBES in benign esophageal strictures was established: The risk score ranged from 0 to 8 points, and the risk scores were divided into low risk (0-2 points), intermediate risk (3-5 points), and high risk (6-8 points). The proportions of RBES in the corresponding risk categories were 1.0%, 12.2%, and 76.0%, respectively. Among 507 patients, 57 had RBES (39 males;median age, 60 years). The success rate of dilation treatment (51.2%, 21/41) was higher than that of stent placement (37.5%, 6/16). CONCLUSION In this study, 11.3%(57/507) patients had RBES at our hospital. The risk-scoring model predicting RBES in benign esophageal strictures could predict the longterm outcome of patients with strictures ahead.展开更多
