To determine the efficacy of Venastent - a novel iliac vein stent for non-thrombotic lesions (NIVLs). From October 2018 to January 2021, 256 NIVL patients were recruited at 19 Chinese hospitals. A randomised controlled trial was conducted compare new stent-Venastent (Tianhong China) with Zilver (Cook USA). All allocated randomly two groups: experimental group used Venastent, while control recei...

PURPOSE The use of stent-grafts has proved to be safe and effective treatment for complicated aortic dissections but usually requires surgical cutdown to accommodate large-profile devices. Preliminary results of the use of a low-profile design that allows percutaneous access are presented. MATERIALS AND METHODS Fifteen patients with aortic dissection were treated with use of a low-profile ste...

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.

We compared the procedural success, mechanism of failure, and safety of percutaneous coronary intervention in 235 procedures for de novo chronic total occlusions with 78 procedures for chronic occlusive in-stent restenosis. Despite similar rates of procedural success and safety profile, angiographic predictors of successful percutaneous coronary intervention for de novo chronic total occlusions...

We report the first clinical use of a new, flexible, low profile, balloon-expandable metallic stent and delivery system (ACS Multi-Link). The stent, designed in an effort to overcome the shortcoming of existing stents, has a low metal mass, superior scaffolding properties and favourable rheological characteristics. It also allows side branch access and is delivered via an innovative stent cathe...

the invention of the drug-eluting stent (des) has brought about revolutionary changes in the field of interventional cardiology. in the des era, in-stent restenosis has declined but new issues such as stent thrombosis have emerged. one of the emerging paradigms in the des era is stent fracture. there are reports about stent fracture leading to in-stent restenosis or stent thrombosis. most of th...

BACKGROUND Small vessels represent a risk factor for restenosis in percutaneous coronary angioplasty (PCA). The Sparrow® self-expanding drug-eluting stent, which has a lower profile than the current systems, has never been tested in this scenario. OBJECTIVES To evaluate the late effectiveness of the Sparrow® drug-eluting stent, regarding in-stent late lumen loss (LLL). METHODS Patients with...

Introduction: Individual oral stent is a mouth-opening device that used in head and neck cancer radiotherapy with the intention of decreasing radiation dose to health tissues. The aim of this study was to check the dose delivered to both the hard palate and tongue when patient uses the stent during radiotherapy of tongue carcinoma. Methods and materials<stron...

Introduction: This study aimed to evaluate the effects of four-time inflation of the stent balloon at nominal pressure on optimal stent expansion in resistant lesions. Materials and Methods: This interventional study was conducted on 39 patients with coronary artery lesions, in whom Zotarolimus-eluting stents (N=20), Paclitaxel-eluting stents (N=11) and other stents (N=8) were deployed four tim...
