BACKGROUND AND PURPOSE: Although mechanical thrombectomy (MT) appears to be superior in stroke patients with extracranial carotid disease (ECD) compared to thrombolysis alone, the impact of emergent carotid stenting during MT remains unclear. We assessed the MT outcomes in anterior stroke patients with ECD, especially when combined with carotid stenting. METHODS: We performed a retrospective analysis of our registry and conducted an update of a systematic review and meta-analysis of MT studies with or without stenting for anterior circulation stroke with ECD published between November 2010 and April 2017...

Placement of multiple metal stents (MS) for the management of high-grade malignant hilar biliary obstruction (MHBO) is useful,1,2 and biliary radiofrequency ablation (RFA) has been suggested to improve stent patency.3,4 However, to our knowledge, there are no reports of RFA procedures performed using a single-balloon endoscope (SBE) in patients with surgically altered anatomy. Here, we report a successful case of RFA combined with multiple MS placement using SBE in Roux-en-Y gastrectomy. This article is protected by copyright...

INTRODUCTION: Cerebral-protection devices (CPDs) are a well-established system for reduction of embolic risk in carotid artery angioplasty and stenting (CAS). Although rare, adverse events with CPDs are unpredictable and can be associated with serious outcomes and iatrogenic sequelae. PRESENTATION OF CASE: We describe the unique case of dislocation of a FilterWire EX™ filter loop during right CAS. On trying to recapture the CPD filter at the end of the procedure, the filter loop suddenly detached from the guidewire and dislocated to the proximal middle cerebral artery...

Robotic percutaneous coronary interventions have recently been introduced in the cardiac catheterization laboratory. Robotics offers benefits of greater precision for stent placement and occupational hazard protection for operators and staff. First generation systems were able to advance and retract coronary wires, balloons, and stents, but did not have guide control functions. The second-generation robotic system (CorPath GRX) has an active guide management function offering the ability to move guide catheters...

Drug eluting stents (DES) based on polymeric-carriers currently lead the market, however, reports on clinical complications encourage the development of safer and more effective DES. We recently reported on carrier-free DES based on rapamycin crystalline coating as a potential therapeutic solution. Here, we report for the first time surface crystallization of paclitaxel (PT) onto metallic stents. The physicochemical principles of crystallization and key process parameters were extensively studied for fabrication of controllable and homogeneous crystalline coatings on stent scaffolds...

Magnesium (Mg) alloy-based bioresorbable scaffolds (BRSs) are attracting interest as next-generation stents. However, because medical Mg alloy materials degrade relatively quickly in physiological media, surface corrosion protection via biodegradable polymer coatings is important for clinical applications. Herein, the influence of biodegradable polymer coatings on the BRS corrosion was investigated. First, elution of the drug sirolimus (SRL) from various biodegradable polymers was estimated, including poly(d,l-lactic acid) (PDLLA), poly(d,l-lactic acid-co-ε-caprolactone) (PLCL) and poly(ε-caprolactone) (PCL)...

The fabrication and performance of mechanically responsive multilayer superhydrophobic composites are reported. The application of tensile strain triggers the release of small molecules and proteins from these composites, with different tensile strain magnitudes and coating thickness influencing agent release. These mechanoresponsive composites consist of an absorbent drug core surrounded by an electrosprayed superhydrophobic protective coating that limits drug release in the absence of tensile strain. Coating thickness and applied tensile strain control release of chemotherapeutic cisplatin and enzyme β-galactosidase, as measured by atomic absorption and UV-vis spectrophotometry, respectively, with preserved in vitro activity...

BACKGROUND: In single ventricle patients, aorticopulmonary collaterals (APCs) and pulmonary arteriovenous malformations (PAVMs) following superior cavopulmonary shunt (CPS) can complicate orthotopic heart transplant (OHT) by cyanosis and hemoptysis. Though PAVMs can regress with restoration of hepatic venous flow to the pulmonary circulation, the effects of hypoxemia on the "unconditioned" allograft are not known. CASES: Two patients with significant PAVMs after CPS were cyanotic following OHT...

BACKGROUND: Helicobacter pylori has undergone considerable adaptation to allow chronic persistence within the gastric environment. While H. pylori-associated diseases are driven by an excessive inflammation, severe gastritis is detrimental to colonization by this pathogen. Hence, H. pylori has developed strategies to minimize the severity of gastritis it triggers in its host. Superoxide dismutase (SOD) is well known for its role in protecting against oxidative attack; less recognized is its ability to inhibit immunity, shown for SOD from mammalian sources and those of some bacterial species...

Cangrelor is an intravenously administered P2Y12 receptor antagonist with very fast, potent, and quickly reversible action. In the CHAMPION PHOENIX trial, cangrelor provided an improved anti-ischemic protection compared with clopidogrel, without increasing the risk of severe bleeding. Cangrelor is currently approved by drug regulating authorities for patients undergoing percutaneous coronary intervention (PCI) without prior treatment with a P2Y12 receptor antagonist and not receiving a glycoprotein IIb/IIIa inhibitor, while its use is endorsed with a class IIb recommendation by the European Society of Cardiology guidelines...

BACKGROUND: Cancer patients with recently placed drug-eluting stents (DESs) often require premature dual antiplatelet therapy (DAPT) discontinuation for cancer-related procedures. Optical coherence tomography (OCT) can identify risk factors for stent thrombosis such as stent malapposition, incomplete strut coverage and in-stent restenosis and may help guide discontinuation of DAPT. METHODS: We conducted a single-center prospective study in cancer patients with recently placed (1-12 months) DES who required premature DAPT discontinuation...
