Objectives: Ideally, guidewires used during peripheral vasculature (PV) interventions could serve both as a therapy delivery platform and a diagnostic tool for real-time vessel sizing (2-in-1 function).
Objective: To identify the specific caseload to overcome learning curve effect based on data from consecutive patients treated with Intracranial Angioplasty and Stenting (IAS) in our center.
Iatrogenic arteriovenous fistula is not a common complication of central venous catheterization. Duct occluder devices have been developed for patent ductus arteriosus occlusions but they may be used for arteriovenous fistula closures. We report a case of iatrogenic brachiocephalic-jugular and aortopulmonary artery fistulas after central venous catheter insertion. The fistulas were successfully managed with duct occluder devices. Due to increasing number of central venous catheterizations, physicians should be aware of this uncommon complication. Transcatheter closing of brachiocephalic-jugular and aortopulmonary artery fistulas by duct occluder devices seems to be a safe and feasible form of treatment. © 2013 Wiley Periodicals, Inc.
Retroperitoneal fibrosis is a rare condition characterized by the presence of inflammatory and fibrous retroperitoneal tissue that surrounds and often encases abdominal structures. In this report we describe an unusual presentation of retroperitoneal fibrosis and inferior vena cava (IVC) obstruction that was unidentified by noninvasive testing and ultimately diagnosed using exercise right heart catheterization and venography. Exercise hemodynamic catheterization revealed a high pressure gradient across the IVC obstruction during exercise that resulted in reduced preload and inappropriately low cardiac output reserve. The patient ultimately underwent angioplasty and stenting of the obstruction resulting in resolution of his symptoms. © 2013 Wiley Periodicals, Inc.
Background: Statins stabilize atherosclerotic plaque, decrease mortality after surgical procedures, and are linked to anti-inflammatory effects. The objective of this study was to evaluate preoperative administration of statins and longitudinal limb salvage after lower extremity endovascular revascularization and lower extremity open surgery.
Background: Recent technical advances have made endovascular treatment (EVT) an alternative first-line treatment for critical limb ischemia.
Peripheral artery disease (PAD) is one of the most common cardiovascular diseases and is associated with high short-term morbidity and mortality.1,2 It is the primary cause of lower extremity amputation throughout the world and is a powerful marker of advanced systemic atherosclerosis. Chronic critical limb ischemia (CLI) represents the most advanced clinical manifestation of PAD and is defined by the presence of ischemic rest pain, nonhealing wounds, or tissue loss (gangrene). CLI does not represent a single pathophysiologic process (ie, progressive leg arterial atherosclerosis), but is caused by multiple pathogenetic mechanisms, including native artery atherosclerosis, cardioembolic events, inflammatory arteritides (eg, thromboangiitis obliterans), hypercoagulable states, or leg bypass graft failure.
Background: Endovascular repair of the thoracic aorta has become an increasingly utilized therapy. Although the short-term mortality advantage over open surgery is well documented, late mortality and the impact of presenting pathology on long-term outcomes remain poorly reported.
Introduction: The optimal treatment of in-stent restenosis (ISR) is not determined. We describe the efficacy of carotid endarterectomy (CEA) with stent removal in the management of symptomatic ISR.
Objective: The lower procedural risk associated with endovascular aneurysm repair (EVAR) compared with open aneurysm repair (OAR) is well known. Younger patients are likely to represent a group at low perioperative risk. The long-term durability and late complications following EVAR may have more significance when considering the optimal treatment for young patients with a longer life expectancy. This study examined perioperative and long-term outcomes of young patients undergoing aneurysm repair by either open surgical or endovascular means.
Objective: Evaluation of variation in descending thoracic aortic aneurysm (dTAA) diameters measured on CT scans in different planes and by different observers and the potential impact on treatment decisions.
Objective: We evaluated the feasibility of visceral artery and lumbar artery (LA) embolization using AMPLATZER vascular plug (AVP) types 4 and 2 (AVP4, AVP2) prior to endovascular aneurysm repair (EVAR) to prevent the development of a type II endoleak.
Objective: Acquiring contemporary data on prevalence and natural history of abdominal aortic aneurysms (AAA) is essential in the effort to optimise modern screening programmes. The primary aim of this study was to determine the fate of a 65-year-old male population 5 years following an invitation to an aortic ultrasound (US) examination.
Background: Several studies have examined inter-observer variability in measurements for standard EVAR, but little is known about measurements for complex aortic aneurysm.
Objectives: Inadvertent intra-arterial injection of flunitrazepam tablets intended for intravenous use by drug abusers has devastating effects. We report here on the clinical outcome of 16 drug abusers developing critical limb ischaemia after flunitrazepam injection.
