[Normal and pathologic semiology of the anterior choroidal artery].
In the normal individual, the anterior choroidal artery (ACA) has a rather fixed angiographic trajectory, but in patients with intracranial tumors it almost invariably has a modified course, the nature of the modification being dependent on the topography of the lesion. Authors employ the parameters used up through the present for objectivating the course of the anterior choroidal artery, and add others of theirs own, especially in regard to the relative location of various points on the vessel (rather than their isolated positions). A total of 28 measurements were taken for each of the 132 angiographic series studied: 31 normal individuals and 101 with diverse intracranial lesions. Every value was entered into a computer along with (by numerical coding) personal data, incidental factors and, in the pathological series, the topography of the preferrent (primary) lesion and secondary lesion (tumoral extension), as well as the possible coexistence of hydrocephaly and/or transtentorial herniation. This procedure allowed for an exhaustive analysis of each factor involved, which could be studied individually or in combination within each of the groups and subgroups established. In this way the extensive results could be readily interpreted.
