Coronary stent dislodgement is a rare and serious complication of percutaneous coronary intervention and is associated with major adverse cardiac events. Successful retrieval of the stent is recommended in this situation because it is important for the prognosis. Recently, a patient was referred to our hospital with a dislodged coronary stent. When attempting to percutaneously extract the dislo...

Trapping of interventional devices used to treat in-stent restenosis is rarely reported in the literature. Among those is a trapped rota ablation wire causing longitudinal stent deformation, sometime requiring another stent deployment onto the collapse stent. A Rota ablator getting stuck into the stent is very rare, and a lethal complication. We report a case of 79-year-old gentleman who underw...

AIMS The purpose of this study was to evaluate the Genous(TM) endothelial progenitor cell capturing stent vs. the Taxus Liberté paclitaxel-eluting stent in patients with de novo coronary lesions with a high-risk of coronary restenosis. METHODS AND RESULTS We randomly assigned 193 patients with lesions carrying a high risk of restenosis to have the Genous stent or the Taxus stent implanted. Le...

AIM To evaluate the technical feasibility and safety of covered airway stent placement for malignant tracheobronchial strictures in patients with an endotracheal tube. MATERIALS AND METHODS Data regarding retrievable, expandable, metal stent placement under fluoroscopic guidance in 20 patients with an endotracheal tube inserted for malignant tracheobronchial strictures were retrospectively an...

Rectal diverticulum is a rare condition in dogs characterized by formation of a pouch or sac due to hernial protrusion of the mucous membranes through a defect in the muscular coat of the rectum. A 12-year-old male terrier dog was admitted with a history of a left perineal swelling, dyschezia and tenesmus during the last five months. Digital rectal examination identified a weakness in the left ...

The Neuroform EZ Stent System is a fourth generation intracranial aneurysm stent that utilizes an integrated navigation guidewire. While designed to facilitate stent delivery, the guidewire can rarely impede proper positioning of the stent. In this technical case report, severing the guidewire from the stent delivery system with surgical scissors was required for successful stent implantation.

PURPOSE Determining the ideal length of a ureteric stent is important to avoid complications associated with stent placement. Clinically, most urologists usually choose the length of a ureteric stent according to the patient's height. On the basis of a Chinese population study, a 22 cm ureteric stent has been recommended for patients smaller than 175 cm. We evaluated the appropriateness of this...

Balloon angioplasty of ostial left anterior descending coronary artery (LAD) lesions has been associated with a high rate of acute complications and late restenosis. Recently, coronary stenting has been proposed as an effective treatment modality for ostial LAD lesions. To evaluate the effects of stent design on the development of late restenosis, we retrospectively analyzed the efficacy of slo...

BACKGROUND Endoscopic stenting is a widely used method for managing esophageal anastomotic leaks and perforations. Self-expanding metal stents (SEMSs) have proved effective in sealing these defects, with a lower rate of displacement than that of self-expanding plastic stents (SEPSs) as a result of tissue proliferation and granulation tissue ingrowth at the uncovered portion of the stent, which ...

BACKGROUND AND PURPOSE SACE is performed for complex aneurysms. There are several configurations of stent placement for bifurcation aneurysms. We investigated hemodynamics among 8 different configurations of stent placement, which may relate to the recanalization rate. MATERIALS AND METHODS We created a silicone block model of a patient-specific asymmetric bifurcation aneurysm. Enterprise clo...
