CONTEXT Many patients with intermittent claudication continue to be forwarded to the vascular surgeon for initial evaluation after arteriography has already been accomplished. OBJECTIVE The main objective of this work was to analyze the usefulness and the need for this procedure. TYPE OF STUDY Retrospective study. SETTING The patients were divided into two groups: Group 1, with the arteri...

We retrospectively assessed the diagnostic value of cerebral arteriography for the search of an etiology in 102 patients with nontraumatic intracerebral hemorrhages evaluated between 1980 and 1985. Arteriography was diagnostic in 22 of 50 non-hypertensive patients and in only 6 of 47 hypertensive patients. Five patients with a bleeding diathesis had normal arteriography. From the total group, w...

Cerebral ischemic events associated with arteriography are usually attributed to catheter-induced emboli. We present three patients with cerebral ischemia occurring 6 to 48 hours post-arteriography. We suspected that alternate pathogenic mechanisms were in effect. To evaluate the possibility that sustained platelet activation occurs in association with arteriography, we measured the platelet-sp...

Digital arch arteriography is a technique in which the cervicocerebral vasculature is studied by injecting small amounts of contrast material (20 ml or less of diatrizoate meglumine 60%) into the aortic arch. It was used as the initial phase of arteriography in 100 patients with cerebrovascular disease. Five to ten series were obtained in various projections to evaluate the cerebrovascular syst...

Background: Arteriography has been considered the “Gold Standard” for the investigation of Peripheral arterial occlusive disease (PAOD). The development of Colour flow Doppler (CFD) has extended the scope of non-invasive assessment of chronic lower limb arterial disease. Aims: To evaluate and correlate the findings of CFD with arteriography as the gold standard, in PAOD of the lower extremities...

PURPOSE To test the feasibility of carbon dioxide (CO(2))-enhanced computed tomographic (CT)-arteriography in an animal model. MATERIALS AND METHODS Five domestic swine underwent digital subtraction angiography (DSA), conventional CT angiography with iodinated contrast material, and CO(2)-enhanced CT arteriography. For each CO(2)-enhanced DSA image series, 100 mL of pressurized CO(2) was inje...
