title: [On the phenomena of extravasation of contrast media in cerebral angiogram of the case of hypertensive intracerebral hematoma and their clinical significance-analysis of 14 cases (author's transl)]?
abstract: Since Westerburg (1966) reported a case of hypertensive intracerebral hemorrhage who showed extravasation of contrast media on the cerebral angiogram, only 21 cases demonstrated extravasation of contrast media were reported by several authors. The author experienced 14 cases of hypertensive intracerebral hemorrhage whose cerebral angiogram showed extravasation of contrast media. These 14 cases occupied 21.1% of 58 cases whom cerebral angiographies were performed within 24 hours after the stroke. 6 out of 14 cases were cured by evacuation of the hematoma surgically. These 14 cases were dividied into three types by the shape of extravasation of contrast media as followed: Type I showed widespread leakage of contrast media. Type II showed sash-like leakage of contrast media surrounded by diffuse thin shadow and Type III showed small spotlike leakage of contrast media. These three types indicated the arterial bleeding stage, the stage of accerelated arterial wall permeability and the subsquent venous bleeding respectively. The author concluded that these extravasation of contrast media not only demonstrated the bleeding artery but also indicated the process of the hematoma formation in each case.
