Tolerance to contrast media in renal angiography

Cerebral angiography; tolerance for contrast media of diodrast type.

Cerebral angiography was introduced by Moniz in 1927. Although increased experience has widened the indications for the method, its general application has been limited because of the difficulty of the injection technique and because of some undesirable results obtained with the use of the -contrast media hitherto available. The operative exposure of the carotid artery limited the application o...

Iso-Osmolar versus Low-Osmolar Contrast Media in Reducing Contrast Induced Nephropathy in Patient with Renal Impairment Undergoing Coronary Angiography

Removal of contrast media from the coronary sinus attenuates renal injury after coronary angiography and intervention.

b t s t b a t b o the Editor: Acute renal injury after exposure to radiographic ontrast media, contrast-induced nephropathy (CIN), accounts for substantial proportion of all cases of acute renal failure (1). The ncremental presence of predisposing factors including pre-existing hronic renal impairment, contrast load, diabetes, and advancing ge contribute significantly to the risk of CIN, which ...

Renal failure after radiological contrast media.

Over a 12-month period four patients developed acute renal failure after undergoing radiological investigations using contrast media. Though the incidence of serious complications is low, the possibility of adverse side effects must be weighed against the usefulness of the information provided by these techniques.

Viscosity of contrast media perturbs renal hemodynamics.

Contrast-induced nephropathy is a common cause of acute renal failure, and the mechanisms underlying this injury are not completely understood. We sought to determine how physicochemical properties of contrast media may contribute to kidney damage in rats. We administered contrast media of equivalent iodine concentrations but differing physiocochemical properties: the high-osmolality iopromide ...
