PURPOSE: To determine the predictors of restenosis, major adverse limb events (MALEs), postoperative death (POD), and all-cause mortality after repeat endovascular treatment of superficial femoral artery (SFA) restenosis. MATERIALS AND METHODS: This was a retrospective review of 440 patients with 518 SFA lesions who were treated between January 2002 and October 2011. Ninety-six limbs were treated for restenosis with bare metal stents (BMSs) or percutaneous transluminal angioplasty (PTA), of which 28 limbs developed another restenosis requiring a third procedure...

BACKGROUND: Carotid artery stenting has emerged as an alternative to carotid endarterectomy especially in patients with high risk of carotid endarterectomy. Older age (≥80 years old) was recognized as one of the high risk factors of carotid endarterectomy. However, the association between older age and increased risk of adverse events for carotid artery stenting has been reported. The purpose of this study was to evaluate the association between age and periprocedural outcomes after carotid artery stenting...

BACKGROUND: Atherosclerotic renal artery stenosis reduces renal blood flow (RBF) and amplifies stenotic kidney hypoxia. Revascularization with percutaneous transluminal renal angioplasty (PTRA) and stenting often fails to recover renal function, possibly because of ischemia/reperfusion injury developing after PTRA. Elamipretide is a mitochondrial-targeted peptide that binds to cardiolipin and stabilizes mitochondrial function. We tested the hypothesis that elamipretide plus PTRA would improve renal function, oxygenation, and RBF in patients with atherosclerotic renal artery stenosis undergoing PTRA...

The article is a literature review presenting a comparative analysis of 30-day risks of mortality and complications after carotid endarterectomy and carotid angioplasty with stenting. The risks studied were as follows: myocardial infarction, stroke, transitory ischaemic attacks, bradycardia, hypotension, postoperative haematomas, and damages to the craniocerebral nerves. The authors analysed a series of recently published foreign studies and meta-analyses dedicated to the problem concerned. The obtained findings revealed that carotid endarterectomy turned out to be associated with a higher perioperative risk for the development of myocardial infarction, postoperative haematomas and damages to the craniocerebral nerves, whereas carotid angioplasty with stenting appeared to be associated with an increased risk for the development of stroke, bradycardia and hypotension within the first 30 postoperative days...

OBJECTIVE: Vascular calcifications (VCs) may be a prognostic factor for outcome after endovascular treatment of peripheral arterial disease (PAD). Semi-quantitative analysis with X-ray imaging is the main limiting factor for assessing VCs. The aim of the present study was to find a correlation between the amount of VC with a CT scan quantification and mid-term results of endovascular treatment of TASC C/D femoropopliteal (FP) lesions. METHODS: Patients belonging to two previously published registries (STELLA and STELLA PTX) and who underwent a preoperative CT scan were retrospectively included in the study...

Since the publication of the Tokyo Guidelines in 2007 and their revision in 2013, appropriate management for acute cholecystitis has been more clearly established. Since the last revision, several manuscripts, especially for alternative endoscopic techniques, have been reported; therefore, additional evaluation and refinement of the 2013 Guidelines is required. We describe a standard drainage method for surgically high-risk patients with acute cholecystitis and the latest developed endoscopic gallbladder drainage techniques described in the updated Tokyo Guidelines 2018 (TG18)...

AIM: To fabricate and evaluate the efficacy of individualized intraoral stents to minimize the potential side effects of radiation on oral tissues in patients with early stages of lip cancer. BACKGROUND: Lower lip cancer is a common tumor found almost exclusively in middle-aged and elderly males. Surgery is the most common treatment of choice, although for less extensive lesions, exclusive radiotherapy may be preferred. Some studies have found that the use of intraoral stents in patients with intraoral cancer (e...

In this study, a newly designed drug-release platform composed of an antithrombogenic 2-methacryloyloxyethyl phosphorylcholine (MPC) polymer was introduced, which was impregnated with basic fibroblast growth factor (bFGF) (bFGF/MPC polymer) to enhance the endothelial cell activation. The platform was also coated with an ultrathin micro-patterned diamond-like carbon (DLC) film (DLC/bFGF/MPC polymer) to precisely control the drug release rate and the cell compatibility. The resulting DLC/bFGF/MPC polymer could effectively prolong the bFGF release rate by depositing the micro-patterned DLC...

In this work, rapamycin-eluting poly (d, l-lactic acid) coating (PDLLA/RAPA) was prepared on biodegradable Mg-Nd-Zn-Zr alloy (JDBM) for both in vitro and in vivo investigation of the degradation behaviors of the magnesium alloy stent platform. Electrochemical tests and hydrogen evolution test demonstrated significant in vitro protection of the polymeric coating against magnesium degradation both in short and long term. The 3-month in vivo study on the RAPA-eluting JDBM stent implanted into porcine coronary arteries confirmed its favorable safety, and in the meanwhile revealed similar neointima proliferation compared to the second generation DES Firebird 2 with no occurrence of adverse complications...

Bile duct stenting remains the clinical mainstay for establishing biliary drainage in malignant or benign strictures with successful and stable deep guidewire passage as the sine qua non. Duodenal loop formation of an effectively inserted guidewire may occur occasionally and threatens the procedural success in day-to-day ERC practice, which may even be more troublesome after cumbersome guidewire passage in the first place. Attempts to rescue wire positioning often fail, since the wire is typically in a dead angle with a tendency to completely slip out of postion no matter how the scope or cannula is navigated...

The treatment of patients with extensive disease of the thoracic aorta represents a formidable challenge for the cardiovascular surgeon. The beginning of thoracic aortic endovascular aortic arch repair has promoted the development of different hybrid approaches as the frozen elephant trunk (FET) strategy, which includes classic arch replacement and antegrade stenting of the descending thoracic aorta. It represents an interesting approach for patients with extensive disease of the thoracic aorta, and its application has significantly increased over recent years...

The Tokyo guidelines 2013 (TG13) include new topics in the biliary drainage section. From these topics, we describe the indications and new techniques of biliary drainage for acute cholangitis with videos. Recently, many novel studies and case series have been published across the world, thus TG13 need to be updated regarding the indications and selection of biliary drainage based on published data. Herein, we describe the latest updated TG13 on biliary drainage in acute cholangitis with meta-analysis. The present study showed that endoscopic transpapillary biliary drainage regardless of the use of nasobiliary drainage or biliary stenting, should be selected as the first-line therapy for acute cholangitis...

For relief of coronary obstruction, percutaneous coronary intervention has become a standard-of-care procedure over the past 40 years. Nonetheless, optimal outcomes after coronary stenting require careful attention to antithrombotic therapy. This review aims to summarise the current available evidence and discusses how to integrate scientific knowledge into clinical decisions. In recent years, improvement and modifications of drugs and devices have changed the field tremendously, and substantially benefitted patient outcomes...

REVIEW
Torstein R Meling
Treatment of blood blister-like aneurysms (BBAs) of the supraclinoidal internal carotid artery (ICA) is challenging and the optimal treatment is yet to be defined. The treatment options for ICA BBAS are microsurgery, endovascular therapy, or a combination of the two. The microsurgical armamentarium consists mainly of direct aneurysm clipping with or without protective EC-IC bypass, clip-wrapping, or trap ligation with ICA sacrifice with or without EC-IC bypass. The endovascular treatment options are mainly endovascular ICA ligation, multiple overlapping stents (≥ 3) with or without coiling, covered stents, or flow diverters...

Carly N Richards, Peter A Schneider
Carotid stent angioplasty (CAS) has been shown to protect patient from future stroke long-term efficacy similar to carotid endarterectomy (CEA). The risk of minor stroke in the perioperative period is higher than with CEA and not related to cerebral protection during the CAS procedure since a significant portion of the neurologic events occur between 1 and 30 days following stent deployment. This observation suggests mechanisms integral to the stent itself may be pertinent such as plaque embolization thru the stent struts may occur...
