The data obtained during angiographic and clinical examination of 35 patients with extracranial occlusion of one vertebral artery (VA) have been compared. The clinical picture of extracranial occlusion of one VA may vary. Also, the disease may run an asymptomatic course. The clinical symptoms of injuries to the vertebro-basilar vessels are less pronounced during noticeable occlusive alterations within the system of the carotid arteries. The main pathways of collateral circulation in extracranial occlusion of one VA involve intrasystemic anastomoses (within the system of the subclavian arteries). Of the greatest functional importance is the unoccluded VA.
对35例一侧椎动脉(VA)颅外段闭塞患者的血管造影和临床检查数据进行了比较。一侧VA颅外段闭塞的临床表现可能各不相同。此外,该病可能呈无症状病程。在颈动脉系统出现明显闭塞性改变时,椎基底血管损伤的临床症状不太明显。一侧VA颅外段闭塞时侧支循环的主要途径包括系统内吻合(在锁骨下动脉系统内)。功能上最重要的是未闭塞的VA。
