BACKGROUND We investigated the incidences, predictors, and clinical outcomes of acute and late stent malapposition detected by optical coherence tomography (OCT) after drug-eluting stent implantation. METHODS AND RESULTS We analyzed the OCT images from 351 patients with 356 lesions who received poststent and follow-up OCT examinations. Acute stent malapposition was observed in 62% of lesions....
BACKGROUND Previous randomized trials have showed the superiority of Paclitaxel-eluting stent over bare metal stent in angiographic and clinical outcomes. Coroflex Please stent is a newly developed drug eluting stent using the Coroflex stent platform combined with the drug paclitaxel contained in a polymer coating. PECOPS I trial, one-arm observational study, showed that the clinical and angiog...
Stent under expansion is one of the reasons compromising outcomes percutaneous coronary interventions. The most common cause stent calcium deposited in atherosclerotic plaque. Adequate plaque modification paramount before placement a stent, as options to handle expanded are limited and less effective. In this case report, we explore usage knuckle wire for extrastent modification, after being fa...
the rectum villous tumour is an uncommon pathology in paediatrics, it represent 1% of all the children's malign tumours. an eleven-year-old girl present a rectal adenocarcinoma developed from a villous tumour. the aim of this study is to assess , an overview of litterature, the frequency of rectum villous tumours; to specify the value of the clinical examination , of the radiologic finding in t...
methods study on 34 patients diagnosed with rectal adenocarcinoma referred to oncology clinic was conducted. the treatment plan included 4050 cgy radiotherapy and 5fu, xeloda chemotherapy. all patients were assessed with 1/5 t mri 6 to 8 weeks after treatment. t1 and t2 images with sagittal, cronal and axial planes with and without contrast agent were obtained and interpreted by two radiologist...
We presented a case that an acute in-stent thrombosis after the deployment of a Wingspan stent was successfully managed with a stent in-stent technique. Because vessel perforation and subarachnoid hemorrhage were iatrogenically developed during the procedure, we were unable to use the thrombolytic agents to correct the in-stent thrombosis. When a thrombotic complication following an intracrania...
OBJECTIVE Neointimal hyperplasia is a major complication of endovascular stent placement with consequent in-stent restenosis or occlusion. Improvements in the biocompatibility of stent designs could reduce stent-associated thrombosis and in-stent restenosis. We hypothesised that the use of a diamond-like carbon (DLC)-coated nitinol stent or a polyethylene glycol (PEG)-DLC-coated nitinol stent c...
AIM To compare polytetrafluoroethylene stent graft (PTFE) with sirolimus and bare metal stents in reducing in-stent restenosis in native coronary vessels in patients with acute coronary syndrome. METHODS The study included patients who underwent stent implantation in acute coronary syndrome from January 2003 to May 2004. The patients (n=119) were randomized either to stent graft group (n=40),...
OBJECTIVE We wanted to evaluate usefulness of uncovered stent in comparison with covered stent for the palliative treatment of malignant colorectal obstruction. MATERIALS AND METHODS Covered (n = 52, type 1 and type 2) and uncovered (n = 22, type 3) stents were placed in 74 patients with malignant colorectal obstruction. Stent insertion was performed for palliative treatment in 37 patients (c...
