Intracerebral leakage of contrast medium in apoplexy.

Abstract Forty-four angiograms, which were performed within three weeks of the onset of hypertensive cerebral haemorrhage, have been reviewed. Leakage of contrast material from cerebral vessels into haematoma was observed in five cases in which cerebral angiography was performed within a few hours after the apoplectic attack. It appears reasonable to presume that the shorter the interval between the onset of the haemorrhage and the angiography, the higher the incidence of extravasation of contrast into the haematoma.
