【摘要】：目的运用容积CT数字减影血管成像(volume CT digital subtraction angiography,VCTDSA)对后交通动脉(posterior communicating artery,PCoA)进行形态学研究。方法收集我院在2016年3月至12月期间行头颈血管VCTDSA检查158例被检者,并行VR、slab MIP图像后处理。观察158例(316侧)被检者PCoA的变异、走形、有无漏斗样膨大,测量PCoA直径、基底动脉(basal artery,BA)直径、漏斗直径、PCoA发出角度。结果 (1)PCoA变异和走形:缺如52.8%,发育不良8.9%、胚胎型17.1%、成人型21.2%。PCoA弯曲64.5%、平直35.5%。胚胎型更多呈平直,成人型更多呈弯曲(χ~2=7.5,P=0.006)。(2)PCoA直径和发出角度男女、左右均未见统计学差异。总平均BA直径与总平均PCoA直径呈明显负相关,(r=-0.998,P=0.000)。(3)漏斗发生率为26%(32/121),漏斗组与非漏斗组间的PCoA变异(χ~2=10.2,P=0.001)、PCoA直径(t=-5.7,P=0.000)及发出角度(t=-3.2,P=0.002)有统计学差异。结论 (1)PCoA直径和BA直径呈明显负相关。(2)成人型、直径更小、发出角度越小的PCoA越容易发生漏斗。
[Abstract]:Objective to study the morphology of posterior communicating artery (PCoA) by volume CT digital subtraction angiography VCTDSA.Methods from March to December 2016, 158 patients underwent VCTDSA examination of head and neck vessels in our hospital. Post-processing of slabs of MIP images was performed. The variation of PCoA was observed in 158 patients (316 sides) with or without funnel-like enlargement. The diameter of PCoA and the diameter of basilar artery were measured. Results the diameters of the funnel and the shape of the PCoA were as follows: 52.8%, hypoplasia 8.9, embryonic 17.1, adult 21.2%.PCoA 64.5, straight 35.5.The embryonic type was more straight, and the adult type was more curved (蠂 27.5P0.006N .2PCoA diameter and angle of emission, male and female). There was no statistical difference between the left and the right. There was a significant negative correlation between the total average BA diameter and the total average PCoA diameter. The incidence of the funnel was 260.32 / 121g. The PCoA variation between the funnel group and the non-funnel group (蠂 ~ 2 / 10. 2P ~ (0.001) P ~ (0.001) PCoA diameters) and the issuing angle (t ~ + -3.2P ~ (0. 002)) were significantly different between the funnel group and the non-funnel group. The diameter of PCoA was negatively correlated with the diameter of BA. The smaller the diameter and the smaller the angle the PCoA is more likely to have funnels.
