Methods The coronary stents were implanted across the necks of 5 intracranial wide-necked aneurysms ( two at bifurcation of ICA , one at basilar artery and two recanalized PcoA aneurysms ) .
方法采用血管内支架结合GDC治疗5例颅内动脉瘤,其中颈内动脉分叉部动脉瘤2例,基底动脉宽颈瘤1例和后交通宽颈动脉瘤复发2例。

On MRA , the presence rate of ipsilateral posterior communicating artery ( PCoA ) in the study group was significantly higher than the controls ( P < 0.01 ), 28 ipsilateral PCoAs were larger ( 47.5 % ) .

-
The rates of the functional patency of the AcoA for men and women were 87.6 % and 83.3 % , left PcoA 28.9 % and 34.1 % , right PcoA 34.4 % and 29.2 % , respectively .

-
On MRA the rate in the study group was significantly higher than the control group ( P < 0 . 01 ), On DSA and MRA , the diameter of ipsilateral PCoA in the study group was larger than the control group ( P < 0 . 01 ) .
在MRA上明显高于对照组(P<0.01);同侧后交通动脉的DSA和MRA测量值均较对照组增大(P<0.01)。
-
Shift of the BA was more likely found in aged individuals . Most of the PCA and SCA were close to the nerve , and a few of them compressed it , as for the PCoA , only the embryonic type was close to or compressed the nerve .
年龄越大BA发生偏移例数越多,多数PCA和SCA与动眼神经紧贴,少数使神经受压,PCoA仅胚胎型与神经紧贴或使之受压。
