PURPOSE: The population of obese patients is increasing in general and also at hemodialysis initiation. For successful cannulation of arteriovenous fistula, the National Kidney Foundation-Dialysis Outcome Quality Initiative guidelines suggest that the required maturation parameters are at a depth of <6 mm. There are several reports describing two-stage superficialization of arteriovenous fistulas in obese cases. Therefore, we investigated the utility and complications of one-stage superficialization of radio-cephalic fistula...

Thrombosis is the most important access-related complication. Several declotting procedures have been suggested falling mainly into two categories; thrombolysis-dependent and thrombectomy-dependent. Areas covered: Seventeen studies after 2001 have been published on percutaneous treatment of thrombosed vascular access. Authors performed a systematic review of these studies together with a parametric meta-analysis of data available investigating clinical success, postintervention assisted primary patency (PAPP) and independent factors that could influence outcome measures...

INTRODUCTION: Percutaneous endovascular therapy is an accepted and preferred procedure for symptomatic subclavian artery disease. However, the technical feasibility and effectiveness of treating chronic total occlusion of the subclavian artery with this approach is uncertain. We aimed to evaluate the initial and mid-term results of endovascular therapy for patients with symptomatic chronic total occlusion of the left subclavian artery. METHODS: Consecutive patients who underwent balloon angioplasty and stenting for chronic total occlusion of the left subclavian artery between January 2010 and February 2014 were included...

Despite advances in drug therapy, pulmonary hypertension-particularly arterial hypertension (PAH)-remains a fatal disease. Untreatable right heart failure (RHF) from PAH eventually ensues and remains a significant cause of death in these patients. Lowering pulmonary input impedance with different PAH-specific drugs is the obvious therapeutic target in RHF due to chronically increased afterload. However, potential clinical gain can also be expected from attempts to unload the right heart and increase systemic output...

OBJECTIVE: Although percutaneous transluminal angioplasty is an effective therapy against vascular access failure in hemodialysis patients, recurrent stenosis imposes enormous burden for hemodialysis patients. A nitinol scoring element-equipped helical balloon catheter (AngioSculpt® ) has been altered the landscape for treating several vascular diseases. It is not, however, fully elucidated whether AngioSculpt for advanced vascular access stenosis, difficult to expand by conventional balloons, successfully provides bailout angioplasty...

OBJECTIVE: To assess feasibility, safety, and patient satisfaction of same-day discharge (SD) following peripheral arterial interventions. BACKGROUND: Although diagnostic angiography is routinely performed as a same-day procedure, same-day percutaneous trans-luminal angioplasty is less common. Because there is very low incidence of peri-procedural complications after 4 hr, discharge after this window is possible provided the patient is able to ambulate and has necessary social support...

OBJECTIVES: To evaluate the association of diabetes mellitus (DM) with clinical and angiographic characteristics and outcomes of patients with popliteal and infrapopliteal peripheral arterial disease (PAD) undergoing peripheral vascular intervention (PVI). BACKGROUND: Clinical features and outcomes in patients with DM and popliteal or infrapopliteal PAD undergoing PVI are not well described. METHODS: Using the data from the laser in popliteal and infrapopliteal stenosis study, we retrospectively examined the association of diabetes with clinical and angiographic characteristics and risk adjusted short- and intermediate term outcomes (all cause death, major adverse events (MAE) [composite of death, ipsilateral major amputation, or repeat revascularization]) in patients with popliteal and infrapopliteal PAD undergoing PVI for critical limb ischemia treated either with laser-assisted balloon angioplasty or balloon angioplasty alone...

Background: The results of recent trials have brought some confusion to the treatment strategy for renal artery stenosis (RAS). To evaluate the applicability of percutaneous transluminal renal angioplasty (PTRA) for RAS, we extracted the factors that may affect the effectiveness of PTRA from cases experienced at a hypertension center. Methods and Results: We retrospectively assessed the blood pressure (BP) lowering effects and renoprotective effects in 50 consecutive patients that had hemodynamically significant RAS and had undergone PTRA and stenting during 2001-2005...

The objectives of central venous percutaneous transluminal angioplasty are to dilate the venous lesion and to extend the life of arteriovenous fistula for hemodialysis. It is reasonable to perform percutaneous transluminal angioplasty for central venous lesions if this interventional therapy is required to maintain stable dialysis therapy. However, the presence of large fresh thrombus at central venous lesion site represents a contraindication to percutaneous transluminal angioplasty unless the thrombus can first be removed by thrombectomy...

BACKGROUND: The treatment of coronary small vessel disease (SVD) remains an unresolved issue. Drug-eluting stents (DES) have limited efficacy due to increased rates of instent-restenosis, mainly caused by late lumen loss. Drug-coated balloons (DCB) are a promising technique since native vessels remain structurally unchanged. METHODS: BASKET-SMALL 2 is a multicenter, randomized, controlled, non-inferiority trial of DCB vs. DES in native SVD for clinical endpoints...

INTRODUCTION: Bioresorbable coronary scaffolds (BRS) have been developed to increase the late safety of coronary angioplasty by providing transitory coronary support and then being fully incorporated to the vessel wall. In the present trial, we sought to evaluate the performance and changes over time in the DESolve™ novolimus-eluting BRS using serial intravascular ultrasound (IVUS) in patients submitted to percutaneous coronary interventions. METHODS: Single-center, prospective, non-randomized study involving 17 consecutive patients submitted to implantation of the DESolve™ scaffold and serial evaluated with IVUS at different time points (post procedure, 6 and 18 months)...

We report three consecutive patients with limb ischemia, where symptoms appeared several days to weeks prior to presentation. In all cases, initial over-the-wire thrombectomy failed due to adherence of the thrombus to the arterial wall. We adopted a new approach of stretching the whole obstructed segment by a series of ballooning using a percutaneous transluminal angioplasty (PTA) catheter. A subsequent thrombectomy was successful in all three cases. No further intervention, such as stenting or bypass surgery, was required...

Contrast-induced encephalopathy (CIE) is a rare complication of angiography. Presently reported is the case of a patient diagnosed with CIE following peripheral angioplasty with the non-ionic contrast agent, iohexol. A 66-year-old male patient described intermittent claudication and peripheral arterial disease was suspected. Lower extremity angiography was performed, and following dilation of a 7.0x150-mm balloon, a 9.0x57-mm stent was placed in the lesioned vessel. The patient subsequently developed confusion and cortical blindness, and a seizure occurred 1 hour after the procedure...
