Introduction To investigate the correlation between the position of a ureteral stent and stent-related symptoms, excluding the influence of ureteroscopic maneuvers. Material and methods From January 2016 to December 2016, we analyzed 130 patients who placed a ureteral stent before ureteroscopic lithotripsy (URSL). A total of 108 patients were enrolled, including 77 (71.3%) men and 31 (28.7%) ...
BACKGROUND Patients with coronary total occlusions are at especially high risk for restenosis and new revascularizations. Sirolimus-eluting stents dramatically improved the clinical outcome of this subset of patients in randomized trials, but other drug-eluting stents, mainly the everolimus-eluting stent (currently the most frequently used stent), have not yet been evaluated in patients with co...
BACKGROUND New-generation coronary stents that release zotarolimus or everolimus have been shown to reduce the risk of restenosis. However, it is unclear whether there are differences in efficacy and safety between the two types of stents on the basis of prospectively adjudicated end points endorsed by the Food and Drug Administration. METHODS In this multicenter, noninferiority trial with mi...
Instent restenosis (ISR) has been a key factor that restricts the further use of intraoronary stents. And the mechanical interaction between the stent and the artery has been indicated as one of the significant causes for the activation of stent-related restenosis. However, there is very little quantitative information about the interaction of stent with artery. In order to improve the general ...
Malignant airway-oesophageal fistulas (AEF) are a serious complication of advance oesophageal or lung cancer. The aim of this study was to assess the quality of life before and after stent insertion, and to examine the role of treatment and location of AEF as factors influencing survival in AEF patients managed with airway and/or oesophageal stent insertion. 112 patients with AEF were included ...
Background: The biolimus-eluting stent (BES), with a biodegradable polymer, has not been previously compared with the everolimus-eluting stent (EES), as a second-generation drug-eluting stent (DES).We sought to compare the 1-year outcome between the PROMUS™ stent (EES type) and the BioMatrix™ stent (BES type). Methods: From March 2008 to September 2011, all patients treated with the PROMUS™ ste...
PURPOSE Temporary drainage of the upper urinary tract by use of internal ureteral stents is a common procedure that is often associated with a variety of symptoms. The role of intravesical stent position in associated morbidity is controversial. MATERIALS AND METHODS The German version of the ureteral stent symptom questionnaire (USSQ) was completed by 73 patients with an indwelling ureteral ...
Percutaneous coronary intervention (PCI) using both balloon angioplasty and coronary stents has markedly reduced adverse cardiac events in patients with ischemic heart disease. Drug-eluting stents (DES) could further decrease the incidence of target vessel revascularization (TVR) to 5%–10% compared to bare-metal stents (BMS) or balloon angioplasty alone.1) Despite its clinical benefits, stent f...
Eccentric stent graft compression: an indicator of insecure proximal fixation of aortic stent graft.
PURPOSE The purpose of this study was to determine whether radiographically demonstrated proximal stent graft contour can be used as a marker for security of proximal neck fixation after endovascular aneurysm repair. METHODS Stent graft structure was examined in 100 consecutive patients with abdominal aortic aneurysms who were treated with the stent graft. Stent graft integrity, stent contour...
AIMS To investigate the efficacy and outcome of emergency percutaneous coronary interventions (PCI) in patients with stent thrombosis. METHODS AND RESULTS Between 1995 and 2003, 6058 patients underwent bare-metal stent implantation, of which 95 (1.6%) patients suffered from stent thrombosis. The timing of stent thrombosis was acute in 10 (11%), subacute in 61 (64%), and late in 24 (25%) patie...
