后交通动脉开放与椎动脉颅内段发育间关系的MRA研究
MRA study on the relationship between posterior communicating artery and the development of intracranial segment of vertebral artery
目的 探讨后交通开放情况与椎动脉颅内段发育之间的关系。 方法 回顾性分析了115例3.0T磁共振血管成像（MRA）体检者。观察双侧椎动脉发育与双侧后交通动脉开放情况，测量椎动脉颅内段管径及后交通动脉的长度与管径，分析二者的相关性。 结果 ①右侧椎动脉发育不良占39.13%（45/115），缺如占0.87%（1/115），左侧椎动脉发育不良占15.65%（18/115），双侧椎动脉同时发育不良占2.61%(3/115)。②单侧或双侧后交通动脉开放72例，双侧同时开放35例，仅左侧开放23例，仅右侧开放14例。③椎动脉颅内段发育不良与后交通动脉开放相关（r=0.677，P=0.000）。 结论 椎动脉颅内段发育不良可引起后交通动脉代偿性开放。
Objective To investigate the relationship between the posterior communicating artery (PCoA) and the development of intracranial segment of vertebral artery. Methods A total of 115 subjects underwent 3.0 T magnetic resonance angiographic (MRA) were involved in this study. The development of vertebral artery and the state of PCoA were observed. The diameter of intracranial segment of vertebral artery, the diameter and length of PCoA were measured. As well, the correlation between them was analyzed. Results ①the frequency of hypoplastic left and right vertebral arteries were respectively 15.65% (18/115) and 39.13%（45/115）, and the absence of the right vertebral artery were in 0.87%（1/115）, the hypoplasia of bilateral vertebral artery were in 2.61%(3/115). 72 patients demonstrated single or bilateral development of the posterior communicating artery, among them 35 cases were bilateral developed, 23 were the left and 14 were the right developed. ③The developing of PCoA was correlated with the development of intracranial segment of vertebral artery（r=0.677，P=0.000）. Conclusions The hypoplasia of intracranial segment of vertebral artery leads to the compensatory developing of the posterior communicating artery.
