脉络丛前动脉虽然比较细小,但在脑血管造影片上可有95％友右的显示率;因其位置近于颅腔中心,供血范围较广,走向及邻接关系相对固定,是一个很好的诊断学标志。有些颅内疾患因部位特殊、脉络丛前动脉可能是唯一的观察对象。为了提高x线诊断水平,我们调查了50例100侧大脑半球,观察了100例正常脑血管造影片,复习有关文献(1～7),对脉络丛前动脉进行了系统的x线解剖学研究。在此基础上,又对100例经过手术证实的颅内疾患之脑血管造影片进行回顾性阅片,以了解该动脉的异常x线表现。现将研究结果报告于后,以供参考。 Although the choroid plexus artery relatively small, but in cerebral angiography film 95% friendly display rate; because of its location near the center of the cranial cavity, a wider range of blood supply to the adjacent and relatively fixed to the relationship is a good Diagnostic signs. Some intracranial disorders due to site specific, choroid plexus anterior artery may be the only observation. In order to improve the diagnostic accuracy of x-ray, we investigated 50 hemispheres of 100 sides, observed 100 normal cerebrovascular angiograms, reviewed the literature (1-7), and systematically studied the anatomic choroidal plexus . On this basis, we retrospectively reviewed the cerebrovascular angiograms of 100 surgically-proven intracranial conditions to understand the abnormal x-ray findings of the artery. The research results are reported later for reference.
