137 consecutive patients with known ankle pressures and diabetic status had attempted femoro-popliteal dilatation for lower limb ischaemia in an English provincial teaching hospital. All except one were followed until failure or death to assess survival and amputation rates. Non-diabetic patients with critical limb ischaemia had a 5 year survival rate of(More)
Fifty patients undergoing 51 percutaneous transluminal angioplasties of the femoropopliteal segment for severe limb ischaemia were reviewed regularly. They comprised 30 men and 20 women of median age 70 (range 56-85) years. There were two deaths within 30 days. At 2 years the cumulative patient survival rate was 60 per cent. Eleven angioplasties were(More)
A prospective study of 370 patients who underwent 500 percutaneous transluminal angioplasties (PTAs) for lower-limb ischemia over a 7-year period was performed. A 97% follow-up rate was achieved. The first PTA was successful in 188 patients (51%). Of the failures, 31% were failed attempts at dilation and 73% occurred within 1 month of intervention. Of the(More)
BACKGROUND AND PURPOSE The efficacy of carotid endarterectomy (CEA) in symptomatic patients with > 70% stenosis is accepted. The stroke risk of asymptomatic patients may not justify surgical intervention. The aim of this study is to use natural history data from a single unit to identify asymptomatic patients who would benefit from CEA. METHODS Five(More)
Non-invasive assessment of the lower-limb vasculature may avoid unnecessary arteriography. Colour duplex scanning of the femoral and popliteal arteries was performed in claudicants who were potential candidates for endoluminal therapy. This was compared with the findings of biplanar conventional arteriography and intra-arterial digital subtraction(More)
A retrospective review of 63 patients undergoing duplex scanning and angiography for suspected carotid artery disease was performed to evaluate the need for routine angiography before carotid endarterectomy. A consultant surgeon (M.H.) made a simulated management decision on the basis of a clinical summary and a duplex scan report. Twenty-four patients were(More)
Accurate diagnosis of internal carotid artery (ICA) occlusion is essential in the investigation of carotid disease yet may be difficult using Duplex. Traditionally contrast arteriography has been used to confirm the diagnosis despite its cost and potential dangers. Twenty-one patients with 23 ICA occlusions were evaluated by a 3-dimensional time of flight(More)
Twenty-seven patients undergoing carotid endarterectomy (21 M, 6 F), with a mean age of 62 years, were studied by carotid ultrasound imaging, angiography, and histological examination of endarterectomy specimens, including Perl's stain to detect haemorrhage more than a week old. Haemorrhage into a plaque was seen histologically in 21 patients (78%),(More)
Angioplasty is an important tool in the armamentarium of the clinician dealing with atherosclerotic disease. Diabetic patients with occlusive disease pose special problems. Four hundred and twenty-five lesions were dilated in 370 patients. No difference in site was found when comparing the diabetic and non-diabetic groups (p less than 0.001), but a(More)
The quoted combined mortality and morbidity following carotid endarterectomy is about 5-7%. In an attempt to identify a subgroup of high risk patients, a review has been undertaken of 404 carotid endarterectomies performed between January 1985 and March 1994. The perioperative mortality rate was 2%, with 3.4% of patients experiencing transient neurological(More)
