PURPOSE To compare the 30-day morbidity, mortality, length of hospital stay, and patency rates in patients with critically ischemic limbs treated with subintimal angioplasty (SA) versus standard bypass surgery. METHOD Between October 2001 and August 2003, 137 patients (74 women; mean age 70 years, range 43-92) with critical limb ischemia underwent(More)
BACKGROUND Plasma Haemoglobin A1c (HbA1c) reflects ambient mean glycaemia over a 2-3 months period. Reports indicate that patients, with and without diabetes, with an elevated HbA1c have an increased risk of adverse outcome following surgical intervention. Our aim was to determine whether elevated plasma HbA1c level was associated with increased(More)
BACKGROUND Popliteal aneurysms account for 70% of peripheral arterial aneurysms and, if untreated, pose a serious threat to the affected limb. Debate continues about the best form of treatment especially for asymptomatic lesions. METHOD We reviewed the computer records and charts of patients seen at this department with a diagnosis of popliteal aneurysm(More)
OBJECTIVES The aim of this study is to assess the influence of subintimal angioplasty (SIA) on lower limb amputation rate and level in critically ischaemic limbs. METHODS Between January 1989 and March 2004, 1268 patients were admitted for treatment of lower limb critical ischaemia. Eight hundred and twenty-nine patients underwent revascularisation(More)
PURPOSE To report 1-year results from the first subgroup of patients treated with the Multilayer Flow Modulator (MFM) stent for aortic aneurysm and dissection. METHODS Up to December 2012, 243 patients have been treated worldwide for aortic aneurysm and dissection with the Cardiatis MFM under the established indications for use. This retrospective review(More)
Accurate characterisation of the mechanical properties of human atherosclerotic plaque is important for our understanding of the role of vascular mechanics in the development and treatment of atherosclerosis. The majority of previous studies investigating the mechanical properties of human plaque are based on tests of plaque tissue removed following(More)
OBJECTIVE It is well known that total cholesterol becomes less of a risk factor or not at all for all-cause and cardiovascular (CV) mortality with increasing age, but as little is known as to whether low-density lipoprotein cholesterol (LDL-C), one component of total cholesterol, is associated with mortality in the elderly, we decided to investigate this(More)
PURPOSE To scrutinize registry data on thoracoabdominal repairs performed using the Multilayer Flow Modulator (MFM) outside the indications for use (IFU) and analyze the adverse outcomes. METHODS Of 380 patients from Europe registered in the MFM Global Registry after treatment for thoracoabdominal aortic aneurysm (TAAA) or dissection, 38 (10%) patients(More)
Little mechanical test data exists regarding the inelastic behavior of atherosclerotic plaques. As a result finite element (FE) models of stenting procedures commonly use hyperelastic material models to describe the soft tissue response thus limiting the accuracy of the model to the expansion stage of stent implantation and leave them unable to predict the(More)
A complete circle of Willis (CoW) is found in approximately 30–50% of the population. Anatomical variations, such as absent or surgically clamped vessels, can result in undesirable flow patterns. These can affect the brain’s ability to maintain cerebral perfusion and the formation of cerebral aneurysms. An experimental test system was developed to simulate(More)
