Arterial hypertension is a common finding in patients with neurofibromatosis (NF) type 1. Renovascular hypertension due to renal artery stenosis or midaortic syndrome could be the underlying cause. We report the case of a 4-year-old girl with NF type 1 and midaortic syndrome whose changes in blood pressure and pulse wave velocity suggested the evolution of vasculopathy, diagnosis of renovascular hypertension, and provided insights of response to treatment. Hypertension persisted after percutaneous transluminal angioplasty in the abdominal aorta, requiring escalation of antihypertensive treatment, while arterial stiffness demonstrated a mild decrease...

BACKGROUND: Existing endovascular therapies for failing infrainguinal bypass grafts are associated with modest patency rates. The use of everolimus drug-eluting stents (eDESs) for endovascular bypass graft revision has not yet been reported. The objective of this study was to describe and to compare clinical outcomes of eDESs vs percutaneous cutting balloons (PCBs) vs percutaneous transluminal angioplasty (PTA) for the treatment of infrainguinal bypass graft stenoses. METHODS: A multicenter, single-institution retrospective analysis of patients with infrainguinal bypass graft stenoses treated by endovascular intervention (August 2010-December 2017) was conducted...

BACKGROUND AND OBJECTIVES: The vascular access pressure ratio test identifies dialysis vascular access dysfunction when three consecutive vascular access pressure ratios are >0.55. We tested whether the magnitude of the decline in vascular access pressure ratio 1-week post-intervention could alert of subsequent access failure. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS: The retrospective study included all vascular access procedures at one institution from March 2014 to June 2016...

AIMS: Stenting of the popliteal artery (PA) is generally considered inappropriate due to the high mechanical stress and bending of the artery during knee flexion. Nevertheless, vessel recoil remains problematic following angioplasty procedure for chronic total occlusions (CTOs) and adjunctive stenting may be required. The purpose of this study is to compare balloon angioplasty alone versus bailout stenting for isolated CTO of the PA. MATERIALS AND METHODS: Between March 2012 and October 2016, 43 patients were treated with percutaneous transluminal angioplasty with balloon alone (PTA, n = 16) or bailout stenting percutaneous transluminal angioplasty and stenting (PTAS, n = 27) for de novo CTO of PA...

Endovascular treatments for vasospasm after subarachnoid hemorrhage are typically performed for patients who are refractory to recommended medical therapies. We analyzed the current status of endovascular treatments based on the data of Japanese Registry of Neuroendovascular Therapy (JR-NET)3, and evaluated factors related to improvement of imaging findings and neurological condition, and to mechanical hemorrhage complications. We collected data of 1211 treatments performed from 2010 to 2014. Target vessels for treatments were anterior circulation (n = 1079), posterior circulation (n = 91), and both (n = 32); the distribution of vasospasm was the proximal vessel (n = 754) to the Circle of Willis, distal vessel (n = 329), and both (n = 119)...

Background: Mechanical thrombectomy (MT) is of clinical benefit for patients with extracranial-intracranial tandem lesions of anterior circulation. However, the optimal approach to the cervical lesion of the internal carotid artery (ICA) during MT has yet to be established. Data on a conservative approach for the proximal lesion during the acute phase are scarce. Methods: A retrospective study on an institutional, prospective database was conducted. We included patients with anterior circulation stroke presenting with a tandem lesion that was approached conservatively during MT...

OBJECTIVE: High grade stenoses of the common carotid artery (CCA) are rare and represent a therapeutic dilemma for the treating physician. Endovascular treatment through antegrade access has been proposed as a less invasive treatment option. The aim of this study is to review the existing literature on such procedure. METHODS: A meta-analysis of all studies reporting on endovascular treatment for the treatment of CCA was performed. RESULT: Six studies, including 227 patients were identified...

Percutaneous transluminal angioplasty (PTA) is the most common therapy used to treat dialysis patients with an occluded arteriovenous fistula (AVF) or arteriovenous graft (AVG). AVF or AVG hemostasis after PTA is time consuming, and it may be complicated with acute thrombosis of the AVF or AVG and re-bleeding from the puncture site. In this study, we prospectively studied 145 hemodialysis patients with occluded AVF or AVG using a modified purse-string suture with short tubing tourniquet technique for hemostasis following PTA, during which we used heparin and urokinase infusion...

OBJECTIVES: The authors sought to investigate the midterm efficacy and safety of drug-coated balloon (DCB) in the treatment of severe femoropopliteal artery disease (FPAD). BACKGROUND: The midterm outcome of DCB versus uncoated balloon percutaneous transluminal angioplasty (PTA) for FPAD are still debated. METHODS: A total of 200 Chinese patients with FPAD were prospectively randomized into treatment with DCB or with PTA. The primary efficacy endpoints were primary patency of the target lesion, freedom from clinically driven target lesion revascularization, improved ankle-brachial index, and improved Rutherford class at 24 months...

Congenital coronary anomalies are rare and reported to occur in 0.64-1.3% of patients undergoing coronary angiography. The dual left anterior descending coronary artery (LAD) is a rare coronary anomaly defined as the presence of two LADs in the anterior interventricular sulcus (AIVS). It consists of a short LAD that ends high in the AIVS and a longer LAD that enters the distal AIVS and feeds apex. Percutaneous interventions are even more uncommon in dual LAD especially Type V LAD. Thus we describe an interesting case of percutaneous transluminal coronary angioplasty (PTCA) with stenting to Type V dual LAD in a patient with chronic stable angina who was refractory to maximal anti-anginal medications...

Background Recent trends in the legalization of marijuana in many states are increasing the popularity of recreational marijuana use. Since current data on hospitalizations in marijuana users is sparse, we evaluated the primary reasons for admissions, procedures and associated healthcare burden in hospitalized recreational marijuana users. Methods The National Inpatient Sample (NIS) for the years 2010-2014 was queried for the hospitalizations with a history of recreational marijuana usage using applicable ICD-9 CM codes...

Intracranial arterial stenosis (ICAS) is a common cause of stroke, and the risk of ischemic stroke from a stenotic intracranial artery remains high despite best medical therapy (BMT). As a result, clinicians have increasingly turned to percutaneous transluminal angioplasty and stenting (PTAS) over the last decade as an alternative therapy in high-risk patients with symptomatic ICAS. In this review, we will critically analyze multiple clinical trials to assess the safety and efficacy of PTAS with BMT versus BMT alone...

OBJECTIVE: Historically, open surgical bypass provided a durable repair among diabetic patients with chronic limb-threatening ischemia (CLTI). In the current endovascular era, however, the difference in long-term outcomes between first-time revascularization strategies among patients with insulin-dependent diabetes mellitus (IDDM) is poorly understood. METHODS: We reviewed the records of all patients with IDDM undergoing a first-time infrainguinal bypass graft (BPG) or percutaneous transluminal angioplasty with or without stenting (PTA/S) for CLTI at our institution from 2005 to 2014...

Due to the implementation of the National Health Insurance system in 1995, the number of patients receiving maintenance dialysis has increased rapidly. This contributed to Taiwan to be in an unfortunate position of possessing the highest prevalence of end-stage renal disease globally. Although the age-standardized incidence of end-stage renal disease gradually decreased to -1.1% in 2014, the huge economic burden that comes with dialysis is detrimental to the quality of dialysis treatment. To achieve a balance between economy and quality of care requires multidisciplinary cooperation...

Coronary artery stenting following balloon angioplasty represents the gold standard in revascularization of coronary artery stenoses. However, stent deployment as well as percutaneous transluminal coronary angioplasty (PTCA) alone causes severe injury of vascular endothelium. The damaged endothelium is intrinsically repaired by locally derived endothelial cells and by circulating endothelial progenitor cells from the blood, leading to re-population of the denuded regions within several weeks to months. However, the process of re-endothelialization is often incomplete or dysfunctional, promoting in-stent thrombosis and restenosis...
