The purpose of the present study was to examine the incidence, causal factors, and anatomic localizations of infarction in the territory of the anterior choroidal artery. We studied 28 patients who had CT evidence of infarction in this territory. The affected structures taken into consideration were the posterior limb of the internal capsule, the retrolenticular portion of the internal capsule, the internal portion of the globus pallidus, and the lateral thalamus. Three conclusions are drawn: that ischemic infarcts in the territory of the anterior choroidal artery are rare, representing 2.9% of all cerebral ischemic lesions in our material; that the incidence of a possible embolic origin is significant; and that the posterior two-thirds of the posterior limb of the internal capsule and the retrolenticular segment are the more frequently affected structures, and conversely, that the medial pallidus and the thalamus are less often involved.
本研究的目的是探讨脉络膜前动脉供血区梗死的发生率、病因及解剖定位。我们研究了28例有该区域梗死CT证据的患者。所考虑的受累结构包括内囊后肢、内囊豆状核后部、苍白球内部和外侧丘脑。得出了三个结论：脉络膜前动脉供血区的缺血性梗死很少见，在我们的资料中占所有脑缺血性病变的2.9%；可能为栓塞起源的发生率很高；内囊后肢后三分之二及豆状核后部是较常受累的结构，相反，苍白球内侧部和丘脑较少受累。
