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)
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)
Intractable bleeding unresponsive to conventional haemostatic measures is an uncommon but potentially life threatening surgical complication. Several studies have suggested that recombinant factor VIIa (rVIIa), a genetically engineered substitute for endogenous factor VIIa may have therapeutic application in patients with uncontrollable haemorrhage not(More)
OBJECTIVE/BACKGROUND To investigate experimentally the arterial wall/device compliance mismatch of four stent-graft devices and a multilayer flow modulator within the supra- and infrarenal locations for the treatment of abdominal aortic aneurysms (AAA). METHODS Five devices (MFM, EndurantII, Excluder, Zenith, and Fortron) were tested under physiological(More)
INTRODUCTION Alteration in the expression of extracellular matrix metalloproteinase inducer (EMMPRIN), matrix metalloproteinase-2 (MMP-2), tissue inhibitors of matrix metalloproteinases (TIMP-2) and platelet derived growth factor (PDGF-AA) may contribute to poor healing in venous leg ulcers. AIM The aim of this study is to determine the expression of(More)
Duplex ultrasound arterial mapping (DUAM) allows precise evaluation of peripheral vascular disease (PVD). However, magnetic resonance angiography (MRA) and digital-subtraction angiography (DSA) are the diagnostic tools used most frequently prior to intervention. Our aim was to compare clinical pragmatism, hemodynamic outcomes, and cost-effectiveness when(More)
BACKGROUND The aim of this paper was to determine prevalence and incidence of intervention required for concomitant Asymptomatic Vascular Disease (AVD) on patients undergoing their first elective peripheral arterial intervention. METHODS This is a prospective observational study Data was obtained on patients undergoing peripheral revascularisation,(More)
Ruptured abdominal aortic aneurysm (RAAA) is a demanding vascular surgical problem and the cause of significant morbidity and mortality. The aim of this study was to identify prognostic factors that influence outcome. Over 6 years, 42 ruptured abdominal aortic aneurysms were operated on with a mean diameter of 7.2 cm. RAAA was defined as free(More)
INTRODUCTION Subclavian stenosis has a prevalence of approximately 2% in the community, and 7% within a clinical population. It is closely linked with hypertension and smoking. There is a relative paucity of published data to inform clinicians on the optimal mode of treatment for subclavian artery stenosis. OBJECTIVES To compare clinical outcomes of(More)
Complications after open aortic surgery pose a challenge both to the vascular surgeon and the patient because of aging population, widespread use of cardiac revascularization, and improved survival after aortic surgery. The perioperative mortality rate for redo elective aortic surgery ranges from 5% to 29% and increases to 70-100% in emergency situation.(More)
