OBJECTIVE: Data in literature suggest iliac artery dilatation and endograft retraction as complications after endovascular aneurysm repair. However, mainly older generation endografts were included. Therefore, we sought to evaluate the distal sealing zone chronological changes after endovascular aneurysm repair with newer generation stent-grafts. METHODS: Clinical and radiological data of patients with abdominal aortic aneurysms treated with endovascular aneurysm repair between January 2010 and December 2013 were reviewed...

INTRODUCTION: Blunt traumatic thoracic aortic injury, the second leading cause of death from trauma, poses unique challenges in its management. However, there has not yet been a corresponding consolidated series of outcomes reported in Asia, which this systematic review aims to address. METHOD: This review was performed as per the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Searches were performed on MEDLINE, EMBASE, Google Scholar, and Cochrane Database for studies performed in Asia reporting the endovascular management of blunt traumatic thoracic aortic injury...

INTRODUCTION: Abdominal endovascular aneurysm repair is a minimally invasive alternative to major open surgery for the repair of abdominal aortic aneurysms that results in reduced recovery times and early survival rates. METHODS: The TriVascular Ovation® Abdominal Stent Graft System is a low-profile endovascular device with active fixation used for endovascular aneurysm repair. The stent graft is designed to reline the diseased vasculature, providing an endovascular blood conduit for isolating the aneurysm from the high-pressure flow of blood, thereby reducing the risk of rupture...

OBJECTIVES: This study aims to present the early results of a prospective study of the use of novel n-butyl-2 cyanoacrylate (VenaBlock)-based nontumescent endovenous ablation with a guiding light for the treatment of patients with varicose veins. METHODS: Five hundred and seventy-three patients with lower-limb venous insufficiency were treated within in the previous four years. The study enrolled adults aged 21-70 years with symptomatic moderate to severe varicosities (C2-C6 patients clinical, etiological, anatomical, and pathophysiological classification) and great saphenous vein reflux lasting longer than 0...

OBJECTIVES: Geometry of carotid artery has been known as a risk factor for atherosclerotic carotid disease. Though aging and disease progression can both attribute to geometric changes in the arteries, the exact nature of this phenomenon remains elusive. The aim of our study was to investigate carotid artery geometric changes in a longitudinal study. METHODS: We conducted a retrospective study of 114 subjects who underwent carotid contrast-enhanced magnetic resonance angiography at our clinic at baseline (2005 to 2007) and after 10 years...

OBJECTIVES: Spontaneous isolated superior mesenteric artery dissection (SISMAD) is a rare disease with an incidence of 0.06%. The purpose of the meta-analysis was to identify the outcomes associated with the various treatment options in the management of asymptomatic and symptomatic patients with SISMAD. METHODS: Eligible studies were selected by searching PubMed, EMBASE, and Cochrane Library. Endpoints were outcome of asymptomatic patients treated conservatively, resolution of symptoms according to the treatment approach, rate of symptomatic patients switched from conservative to the endovascular and/or open repair, characteristics of the dissected lesion, and findings regarding the remodeling of superior mesenteric artery...

OBJECTIVE: Data about renal artery stenosis association with left ventricular remodeling in patients coexisting with coronary artery disease are scanty. METHODS: Patients with suspected both coronary artery disease and renal artery stenosis undergoing coronary and renal arteriography between October 2013 and December 2015 were prospectively enrolled. Left ventricular remodeling patterns were compared among different severity of renal artery stenosis group. Logistic regression was done to investigate the determinants of the left ventricular morphology...

OBJECTIVE: Peripheral artery disease is a major clinical co-morbidity that can significantly affect quality of life, especially in the presence of diabetes mellitus and older age. The focus of this literature review is on medical management, through anti-platelet and anti-coagulation, of peripheral artery disease prior to undergoing surgical or endovascular management. METHOD: Extensive electronic literature search performed in four major databases (PubMed, SCOPUD, Embase and Ovid) to identify the published randomized and non-randomized studies that compared and discussed the management of peripheral artery disease with different anti-thrombotic agents...

BACKGROUND: Whilst the management of blunt traumatic thoracic aortic injury has seen a paradigm shift to an 'endovascular first' approach, the limitations of thoracic endovascular aortic repair remain. An inadequate proximal landing zone limits the use of thoracic aortic stent grafts and in an emergent polytrauma setting, aortic arch debranching via open surgery may not be practical or feasible. A wholly endovascular approach to debranching utilising 'off-the-shelf' stents and parallel graft techniques may represent a possible solution...

OBJECTIVES: The placement of inferior vena cava filters (IVCF) continues to rise. Vascular specialists adopt different practices based on local expertise. This study was performed to assess the attitudes of vascular specialists towards the placement and retrieval of IVCF. METHODS: An online survey of 28 questions related to practice patterns regarding IVCF was administered to 1429 vascular specialists. Vascular specialists were categorized as low volume if they place less than three IVCF per month and high volume if they place at least three IVCF per month...

BACKGROUND: Bivalirudin may be an effective alternative anticoagulant to heparin for use in percutaneous peripheral interventions. We aimed to compare the safety and efficacy of bivalirudin versus heparin as the procedural anticoagulant agent in patients undergoing percutaneous peripheral intervention. METHODS: For this meta-analysis and systematic review, we conducted a search in PubMed, Medline, Embase, and Cochrane for all the clinical studies in which bivalirudin was compared to heparin as the procedural anticoagulant in percutaneous peripheral interventions...

OBJECTIVE: Gender-related differences in outcomes in complex endovascular aortic repair have not been profoundly investigated. Use of low profile abdominal devices as in chimney endovascular repair may be beneficial for female patients with pararenal pathologies. With the chimney technique, there is no need for large introduction sheaths. This could be an advantage in case of smaller in diameter iliac access especially in combination with stenosis or elongation. Aim of the present study was to compare the perioperative and mid-term outcomes between males and females patients treated with the chimney/snorkel technique for pararenal aortic pathologies...
