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)
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)
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)
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)
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)
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)
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 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)
A prospective study of all patients with critical limb ischaemia (CLI) who presented to a single vascular unit was undertaken for a 12-month period. There were 222 referrals in 188 patients, 80.2 per cent of which were emergency or urgent admissions. The majority (72.5 per cent) were initially investigated with colour duplex scanning to characterize the(More)
OBJECTIVE To compare the results of emergency open repair of acute (ruptured or symptomatic intact) abdominal aortic aneurysms with that of endovascular repair. METHODS A systematic literature search was performed to identify series that reported comparative outcomes. PubMed, Embase, the randomized controlled trial (RCT) register, and all relevant major(More)
