BACKGROUND: Data regarding transsplenic portal venous access for diagnostic imaging and endovascular intervention in children are limited, possibly due to concerns regarding high bleeding risks and resultant underutilization. OBJECTIVE: To investigate the safety and utility of transsplenic splenoportography and portal venous interventions in children. MATERIALS AND METHODS: A retrospective review was performed of all pediatric patients undergoing percutaneous transsplenic portal venous access and intervention at two large tertiary pediatric institutions between January 2012 and April 2017 was performed...

BACKGROUND: In young patients with native aortic coarctation (CoA), the management of choice is surgery. However, in re-coarctation (re-CoA) surgery is associated with increased morbidity and even mortality. Some children with native CoA present relative contraindications for surgery. METHODS: From 2006 to 2017, thirty-four patients (male n = 20; 59%) from two centres with re-CoA (31) and native CoA (3) were managed by stent implantation with premounted balloon expandable stents...

Introduction: Most established risk factors after rotational atherectomy (RA) of heavily fibro-calcified lesions are associated with patients' general risk and clinical related factors and are not specific for either coronary and culprit lesion anatomy or the RA procedure. Aim: To assess novel predictors of poor outcome after percutaneous coronary intervention using RA in an all-comers population. Material and methods: A total of 207 consecutive patients after RA were included in a single-center observational study...

The short- and long-term success of intravascular stents depends on a proper re-endothelialisation after the intervention-induced endothelial denudation. The aim of this study was to evaluate the potential of in vivo molecular imaging of glutamate carboxypeptidase II (GCPII; identical with prostate-specific membrane antigen PSMA) expression as a marker of re-endothelialisation. Fifteen Sprague Dawley rats underwent unilateral balloon angioplasty of the common carotid artery (CCA). Positron emission tomography (PET) using the GCPII-targeting tracer [18 F]DCFPyL was performed after 5-21 days (scan 60-120 min post injection)...

Endovascular intervention is a mainstay treatment of peripheral artery disease (PAD) in addition to aggressive risk factor modification and exercise programs in patients with favorable anatomy or in those who are considered too high risk for surgical intervention. Treatment with percutaneous transluminal angioplasty (PTA) and bare metal stents (BMS) has been limited by high rates of in-stent restenosis (ISR) requiring repeat revascularization. Drug-eluting stents (DES), developed and designed to reduce ISR, offer a promising solution to the current challenges in endovascular management of PAD...

Coronary artery disease in patients with diabetes mellitus (DM) is characterized by extensive atherosclerosis, longer lesions, and diffuse distal disease. Consequently, these patients have worse outcomes after coronary revascularization, regardless of the modality used. Traditionally, coronary artery bypass grafting (CABG) has been regarded as more effective than percutaneous coronary intervention (PCI) in patients with DM, likely because of more complete revascularization and protection against disease progression in the bypass segment...

OBJECTIVES: This study was designed to evaluate outcomes of adventitial dexamethasone delivery adjunctive to standard endovascular revascularization in femoropopliteal peripheral artery disease. BACKGROUND: Drug-coated balloons and drug-eluting stents improve patency of endovascular interventions with passive diffusion of antiproliferative drugs. Adventitial dexamethasone delivery targets the initial triggers of the inflammatory reaction to injury, thus potentially providing a potent antirestenotic strategy...

As the number of implanted left ventricular assist devices (LVADs) used increases, the frequency of chronic complications encountered also increases. The pause of blood flow in the outflow graft is a rare, but fatal, complication. The aim of this article was to present the case of a patient in whom HeartWare outflow graft occlusion was removed by balloon angioplasty and to examine the treatment modalities of HeartWare outflow graft occlusions that have been percutaneously performed to date. The literature was searched for percutaneous interventions on outflow grafts of the left ventricular assist devices...

INTRODUCTION: The identification of carotid stenosis in patients proposed for coronary artery bypass grafting, proves that atherosclerosis is a systemic disease. In patients with carotid disease and in need of cardiac surgery, there are still questions about the best method of treatment - medical, surgical or percutaneous, the degree of stenosis considered for intervention and the best time for treatment (pre, peri or postoperative heart surgery). The surgical treatment of the carotid stenosis is currently the gold standard...

INTRODUCTION: Intravascular or catheter embolization of a foreign body, either by fracture or migration, is a rare condition, occurring in approximately 1%. This study is focused on the migration of catheters since they represent the majority of cases of embolization. We present one of the largest published series of removal of foreign bodies with endovascular techniques. The objective of the present study is to demonstrate the different locations where foreign bodies, in most cases catheters, can reach, the technique used to remove them and the affected population...

Introduction Proximal cervical internal carotid artery stenosis greater than 50% merits revascularization to mitigate the risk of stroke recurrence among large-vessel anterior circulation strokes undergoing mechanical thrombectomy. Carotid artery stenting necessitates the use of antiplatelets, and there is a theoretical increased risk of hemorrhagic transformation given that such patients may already have received intravenous thrombolytics and have a significant infarct burden. We investigate the outcomes of large-vessel anterior circulation stroke patients treated with intravenous thrombolytics receiving same-day carotid stenting or selective angioplasty compared to no carotid intervention...

There is limited data on the efficacy of paclitaxel-coated balloon (PCB) compared to stents for de novo coronary lesions. The purpose of this study was to compare the efficacy of PCB treatment with stent implantation for de novo coronary lesions after successful plain old balloon angioplasty (POBA) guided by fractional flow reserve (FFR). In 200 patients scheduled for elective percutaneous coronary intervention (PCI) for de novo lesions, FFR was measured after POBA (POBA-FFR). If POBA-FFR was ≥ 0.75, patients were treated with PCB (PCB group, n = 78) or stent (Stent group, n = 73)...

Guidewire entrapment is a rare complication of coronary intervention, and management depends on the individual circumstances. This is a case of an urgent percutaneous coronary angioplasty in which a guidewire became entrapped behind a bare metal stent with subsequent fracture of the core filament, which could not be retrieved. Using optical coherence tomography, our case demonstrates extensive tissue coverage of the retained guidewire at twelve months. Five-year follow-up suggests that retained guidewires can be managed without long-term anticoagulation, even when there is substantial intra-aortic material...

Carotid artery stenting (CAS) has been recommended as an alternative treatment to carotid endarterectomy for patients with significant carotid stenosis. Only a few studies have analyzed clinical/anatomical and technical variables that affect perioperative outcomes of CAS. Following a comprehensive Medline search, it was reported that clinical factors, including age of >80 years, chronic renal failure, diabetes mellitus, symptomatic indications, and procedures performed within 2 weeks of transient ischemic attack symptoms, are associated with high perioperative stroke and death rates...

OBJECTIVES: Upper arm arteriovenous fistulas (AVF) occasionally develop high flow. Revision using distal inflow (RUDI) effectively reduces flow of high flow accesses (HFA) in the short-term and is also popularised for treatment of haemodialysis access induced distal ischaemia (HAIDI). The long-term efficacy is unknown. The study's aim was to report on 3 year RUDI patency and recurrence rates for HFA with and without HAIDI. MATERIAL AND METHODS: This was a retrospective cohort study of patients with a HFA with or without HAIDI undergoing RUDI using greater saphenous vein (GSV) interposition between March 2011 and October 2017 at three facilities...

PURPOSE: To investigate the potential of real-time magnetic particle imaging (MPI) to guide percutaneous transluminal angioplasty (PTA) of vascular stenoses in a phantom model. MATERIALS AND METHODS: Experiments were conducted on a custom-built MPI scanner. Vascular stenosis phantoms consisted of polyvinyl chloride tubes (inner diameter 8 mm) prepared with a centrally aligned cable tie to form ~ 50% stenoses. MPI angiography for visualization of stenoses was performed using the superparamagnetic iron oxide nanoparticle-based contrast agent Ferucarbotran (10 mmol (Fe)/l)...

Coronary stent implantation has significantly improved percutaneous coronary intervention and enabled the management of early complications of plain balloon angioplasty. However, a new complication has accompanied these improvements: in-stent restenosis (ISR) arising from neointimal hyperplasia. ISR after coronary angioplasty is currently one of the main limitations of this method, leading to the recurrence of exertional angina pectoris or acute coronary syndromes. The clinical incidence of ISR after bare-metal stent (BMS) implantation is approximately 20%-35%...
