A 75-year-old woman was admitted for the extraction of an esophageal fully covered metal stent (upper esophageal sphincter stent [80×20mm]; LeufenMedical, Berlin, Germany). The stent had been implanted 5 weeks earlier to treat an esophageal perforation sustained during bougienage of a benign proximal esophageal stenosis. The location of the stent was distal to the stricture, so that only a tran...

ted, plastic biliary stents may be techni− cally challenging and sometimes unsuc− cessful [1]. Data from the literature report a retrieval success rate of 85%, with the remaining 15% requiring surgical removal [2]. The choice of retrieval technique is dependent on several factors, including biliary ductal dilatation, depth of stent migration, distal stent impaction, and biliary stricture distal...

The Neuroform stent is the first microcatheter-delivered stent designed specifically for the treatment of cerebral aneurysms. The stent functions primarily to provide durable parent vessel protection during the embolization of broad-necked cerebral aneurysms. The present case report demonstrates in-stent stenosis occurring as a delayed complication of Neuroform stent-supported coil embolization...

Drug-eluting stent (DES) implantation is currently the standard treatment for various types of coronary artery disease. However, previous reports indicate that stent fractures, which usually occur after a period of time from the initial DES implantation, have increased during the DES era; stent fractures can contribute to unfavorable events such as in-stent restenosis and stent thrombosis. In o...

We describe a patient suffering from late stent thrombosis in a paclitaxel-eluting stent which had an underexpanded ring due to the three-hundred-sixty-degree circumferential calcified plaque. Intravascular ultrasound (IVUS) revealed rotational atherectomy could successfully ablate both the metallic ring and the calcified ring. The ablated segment was scaffolded with a new paclitaxel-eluting st...

Coronary stent dislodgement is a rare complication of percutaneous coronary intervention. We report a case of stent dislodgement in the ascending thoracic aorta. The stent was mechanically distorted in the left circumflex artery (LCX) while being delivered to the proximal LCX lesion. The balloon catheter was withdrawn, but the stent with the guide wire was remained in the ascending thoracic aor...

BACKGROUND We describe the clinical and morphological patterns of restenosis after sirolimus-eluting stent (SES) implantation. METHODS AND RESULTS From 121 patients with coronary angiography obtained >30 days after SES implantation, restenosis (diameter stenosis >50%) was identified in 19 patients and 20 lesions (located at the proximal 5-mm segment in 30% or within the stent in 70%). Residua...

OBJECTIVE The risk of in-stent restenosis can be considerably reduced by stents eluting cytostatic compounds. We created a novel drug-eluting stent system that includes several new features in the rapidly evolving field of stent-based drug delivery. METHODS AND RESULTS The aim of the present study was the preclinical evaluation of a stent-coating system permitting individual, on-site coating ...

AIMS In many countries, drug-eluting stent implantation is the dominant interventional strategy. We evaluated the clinical, angiographic, procedural, and intravascular ultrasound (IVUS) predictors of angiographic restenosis after sirolimus-eluting stent (SES) implantation. METHODS AND RESULTS SES implantation was successfully performed in 550 patients with 670 native coronary lesions. Six-mon...

Stent thrombosis is a major limitation of stent-assisted coiling, which is an effective method for treating wide-necked aneurysms. Although early in-stent thrombosis has been reported, very late stent thrombosis (VLST) (>1 year) has not been reported following implantation of a single self-expandable stent designed for coiling. Herein, the authors present a case of VLST that occurred 14 months ...
