大多数颅外动脉都有血管，血管在某些病理情况下起重要作用。然而，在颅内动脉中，血管的存在及其病理意义尚未得到充分的研究。我们研究了1987年至1994年间50例尸检病例中大脑大动脉血管血管的分布和发生率及其与某些临床因素的关系。光镜下，50例患者中有36例发现血管血管。36例患者中，30例血管血管局部位于外膜，6例血管血管血管分布于中膜并伴有壁内出血。血管血管的存在在近端动脉（椎动脉、颈内动脉和基底动脉）比远端动脉（大脑中动脉和大脑前动脉）更常见。老年重症动脉粥样硬化患者及脑血管病患者多见血管管。我们的研究结果表明，颅内血管血管在椎动脉和大脑内动脉的外膜中存在的频率较高，并且血管血管的发生率与动脉粥样硬化的严重程度有关。中膜血管血管的发育可能反映了脑动脉的一些病理变化。
Most of the major extracranial arteries have vasa vasorum which play an important role in some pathological conditions. However, in the intracranial arteries, the existence of vasa vasorum and their pathological implication have not been adequately investigated. We examined the distribution and incidence of vasa vasorum in the major cerebral arteries and their relationships to certain clinical factors in 50 autopsy cases performed between 1987 and 1994. By light microscopy, vasa vasorum were found in 36 of 50 patients. Of 36 patients, vasa vasorum in 30 cases were localizedly observed in the tunica adventitia and the in other 6 were distributed in the tunica media accompanied by intramural haemorrhage. Existence of vasa vasorum was more common in the proximal arteries (vertebral, internal carotid, and basilar arteries) than in the distal arteries (middle cerebral and anterior cerebral arteries). Vasa vasorum were found more frequently in aged patients with severe atherosclerosis and those with cerebrovascular diseases. Our results indicated that intracranial vasa vasorum existed with a higher frequency in the tunica adventitia of the vertebral and internal cerebral arteries, and the incidence of vasa vasorum related to severity of atherosclerosis. The development of vasa vasorum in the tunica media may reflect some pathological changes of cerebral arteries.
