BACKGROUND Myocardial and renal injury commonly contribute to perioperative morbidity and mortality after abdominal aortic aneurysm repair. Remote ischemic preconditioning (RIPC) is a phenomenon whereby brief periods of ischemia followed by reperfusion in one organ provide systemic protection from prolonged ischemia. To investigate whether remote(More)
BACKGROUND High-resolution magnetic resonance (MR) imaging has been used for MR imaging-based structural stress analysis of atherosclerotic plaques. The biomechanical stress profile of stable plaques has been observed to differ from that of unstable plaques; however, the role that structural stresses play in determining plaque vulnerability remains(More)
PURPOSE To report a randomized clinical trial designed to determine if remote ischemic preconditioning (IP) has the ability to reduce renal and cardiac damage following endovascular aneurysm repair (EVAR). METHODS Forty patients (all men; mean age 76+/-7 years) with abdominal aortic aneurysms averaging 6.3+/-0.8 cm in diameter were enrolled in the trial(More)
Percutaneous transluminal angioplasty (PTA) alone was used to treat 54 (23 per cent) of 232 lower limbs with critical ischaemia. Technical success was achieved in 49 cases (91 per cent) with an immediate symptomatic improvement in 47 (87 per cent). There was no death or limb loss attributable to PTA and three embolic complications were successfully treated(More)
Visceral artery aneurysm is an uncommon pathology, with a potential for rupture. Splenic artery aneurysms (SAA) are most commonly (60%) associated with a high mortality rate of 25% in case of aneurysm rupture. This increases disproportionately to 75% among pregnant women with fetal mortality of 95%. Although this is a rare event, because of the associated(More)
OBJECTIVES The aim of this study was to evaluate the effects of low-dose (10 mg) and high-dose (80 mg) atorvastatin on carotid plaque inflammation as determined by ultrasmall superparamagnetic iron oxide (USPIO)-enhanced carotid magnetic resonance imaging (MRI). The hypothesis was that treatment with 80 mg atorvastatin would demonstrate quantifiable changes(More)
BACKGROUND The Estimation of Physiologic Ability and Surgical Stress (E-PASS) score was designed on the premise that the balance between the patient's physiologic reserve capacity and the surgical stress inflicted at operation was important in the occurrence of postoperative complications. The aim of this study was to assess its value in predicting(More)
The modes of failure of the sliding hip screw devices were investigated by reviewing 223 cases. There were 35 mechanical failures. Two of these occurred when the components separated in highly comminuted fractures. The use of the locking screw is recommended to prevent this. The other 33 occurred when the device had lost its sliding action. The reasons for(More)
BACKGROUND & OBJECTIVES The aim of this study was to apply three simple risk - scoring systems to prospectively collected data on all elective open Abdominal Aortic Aneurysm (AAA) operations in the Cambridge Academic Vascular Unit over a 6 - year period (January 1998 to January 2004), to compare their predictive values and to evaluate their validity with(More)
The Second European Consensus Document on Chronic Critical Leg Ischaemia defines critical limb ischaemia in non-diabetic patients as rest pain or tissue necrosis (ulceration or gangrene) with an ankle systolic pressure (ASP) of less than or equal to 50 mmHg, or a toe pressure of less than or equal to 30 mmHg. The aim of this study was to investigate whether(More)
