PURPOSE The objective of this study was to assess the initial and 1-year outcome of endovascular treatment of thoracic aortic aneurysms and dissections collated in the European Collaborators on Stent Graft Techniques for Thoracic Aortic Aneurysm and Dissection Repair (EUROSTAR) and the United Kingdom Thoracic Endograft registries. METHODS Four hundred(More)
In Saccharomyces cerevisiae, the GAL genes encode the enzymes required for galactose metabolism. Regulation of these genes has served as the paradigm for eukaryotic transcriptional control over the last 50 years. The switch between inert and active gene expression is dependent upon three proteins--the transcriptional activator Gal4p, the inhibitor Gal80p,(More)
Cerebral small vessel disease (SVD) causes focal lacunar infarction and more diffuse ischaemia, referred to as leukoaraiosis. Endothelial dysfunction has been proposed as a causal mechanism in the disease. Homocysteine is toxic to endothelium. We determined whether elevated homocysteine levels and the methylene tetrahydrofolate reductase (MTHFR) C677T(More)
OBJECTIVE To assess whether a strategy of endovascular repair (if aortic morphology is suitable, open repair if not) versus open repair reduces early mortality for patients with suspected ruptured abdominal aortic aneurysm. DESIGN Randomised controlled trial. SETTING 30 vascular centres (29 UK, 1 Canadian), 2009-13. PARTICIPANTS 613 eligible patients(More)
This population-based cross-sectional study in South London looks at the total homocysteine (tHcy) levels in groups of different ethnic background and the possible role of environmental factors and the 677C-->T genetic polymorphism of the methylenetetrahydrofolate reductase (MTHFR). Fasting plasma tHcy was measured in 1392 men and women, age 40-59 years;(More)
OBJECTIVE Endovascular repair for degenerative aortic aneurysms is well established, but its role in those with infective pathology remains controversial. This study aims to assess the durability of endovascular repair with a review of our midterm results. METHOD A retrospective analysis of a prospectively maintained endovascular database (1998-2008) was(More)
BACKGROUND Endovascular graft designs incorporating sidebranches, fenestrations and scallops offer a minimally-invasive alternative to open surgery and hybrid approaches for thoracoabdominal aortic aneurysms (TAAA). Our unit has offered total endovascular TAAA repair to selected higher-risk patients since 2008. We report the largest UK series to date of(More)
BACKGROUND Late aneurysm formation is a well-recognized complication of surgery for aortic coarctation. Open surgery to repair these aneurysms is associated with significant morbidity and mortality. Endoluminal repair is an attractive alternative to open surgery. METHODS Data were collected prospectively on consecutive patients who presented with(More)
BACKGROUND Thoracic stent grafts offer an alternative to open surgery for thoracic aortic disease, but their long-term durability is unknown. This report includes mid-term follow-up for commercially available thoracic devices. METHODS Data were collected prospectively for a series of endoluminal grafts used to treat thoracic aortic pathology. RESULTS(More)
PURPOSE Mutations in murine and human versions of an ancestrally related gene usually result in similar phenotypes. However, interspecies differences exist, and in the case of two forkhead transcription factor genes (FOXC1 and FOXC2), these differences include corneal or anterior segment phenotypes, respectively. This study was undertaken to determine(More)
