Background: As one of the leading causes vascular morbidity and mortality, peripheral arterial disease (PAD) remains most underdiagnosed undertreated atherosclerotic diseases. The relatively high prevalence PAD combined with an aging population, increasing burden chronic diseases, poor control risk factors will contribute to poorer clinical outcomes in coming decades. Objective...

AN arterio-venous fistula between the internal carotid artery and the cavernous sinus may occasionally present with contralateral signs. Only two other cases have been recorded in which the diagnosis has been confirmed by arteriography (Jefferson, 1952; Ramos and Mount, 1953). Two further cases, not verified by arteriography, have been reported by Walsh (1957) and Dandy and Follis (1941). The l...

We report a patient in whom haemobilia occurred after percutaneous liver biopsy. Selective hepatic arteriography showed a fistula between hepatic artery and portal venous system, with appearance of contrast in the biliary tract. Intrahepatic bleeding was stopped by arterial embolisation with a mixture of gelatine foam and sterile dura mater. Cholecytectomy was subsequently required as a haemoch...

Coronary arteriography was performed before and after the intracoronary injection of nitroglycerin to determine the presence or absence of spasm in patients within the first 12 hours of acute myocardial infarction. Coronary arterial spasm was demonstrated in six of fifteen (40%) acute myocardial infarctions associated with coronary artery disease. In five of the six instances the interval from ...

The first "selective" coronary arteriogram was made 50 years ago by Dr. F. Mason Sones at the Cleveland Clinic. Soon afterward coronary arteriography was developed as a diagnostic method suitable for widespread clinical application. This method has revolutionized our understanding of coronary artery disease and has become the basis for selecting and evaluating therapeutic interventions. This Vi...

Pulmonary thromboembolism is a common condition. Its diagnosis usually requires pulmonary scintigraphy, computed angiotomography, pulmonary arteriography and, in order to rule out other diagnoses, the measurement of D-dimer levels. Due to the fact that these diagnostic methods are not available in most Brazilian hospitals, the validation of other diagnostic techniques is of fundamental importan...

Coronary arteriography revealed significant left anterior descending coronary artery stenosis in a 72-year-old man with a history of myocardial infarction. Stenting of the stenotic vessel was performed. Twelve hours after stenting the patient complained of chest pain but emergent coronary arteriography did not show sign of any coronary arterial stenosis. Under suspicion of coronary thrombus for...
