OBJECTIVE The aim of this study was to quantify the distribution of peripheral arterial disease in the diabetic and nondiabetic population attending for angiography and to compare severity and outcome between both groups of patients. RESEARCH DESIGN AND METHODS Randomly selected lower-extremity angiograms were examined according to the Bollinger system.(More)
Iodixanol (Visipaque, Nycomed, Oslo, Norway) is an iodinated contrast medium in the form of a non-ionic dimer which is iso-osmolar with plasma at all iodine concentrations. There is little evidence regarding its renal tolerance in renal impairment. We therefore undertook a prospective randomized comparison of iodixanol and the non-ionic monomer iohexol(More)
The varicograms of 128 legs were reviewed by a panel of two vascular surgeons and a radiologist with a specialist vascular interest. Varicography effectively elucidates the anatomical basis of recurrence. Recurrent varicose veins were associated with (i) technically unsatisfactory surgery at the saphenofemoral junction (66 per cent) and (ii) failure to(More)
Computed tomography (CT) is more sensitive than the chest radiograph in the detection of pulmonary metastases, but specificity is lower because CT detects more small benign nodules. This study assessed the significance of pulmonary nodules demonstrated on CT when the chest radiograph was normal. Staging CT scans of 146 patients with extrathoracic primary(More)
A retrospective review of all patients presenting to a tertiary referral center with acute nontraumatic upper limb ischemia between January 1992 and June 1997 was undertaken to examine the role of intraarterial thrombolysis in the management of such cases. Twenty-one patients were identified in the radiology and vascular surgery departments' registers.(More)
