【摘要】：目的運用容積CT數(shù)字減影血管成像(volume CT digital subtraction angiography,VCTDSA)對后交通動脈(posterior communicating artery,PCoA)進行形態(tài)學(xué)研究。方法收集我院在2016年3月至12月期間行頭頸血管VCTDSA檢查158例被檢者,并行VR、slab MIP圖像后處理。觀察158例(316側(cè))被檢者PCoA的變異、走形、有無漏斗樣膨大,測量PCoA直徑、基底動脈(basal artery,BA)直徑、漏斗直徑、PCoA發(fā)出角度。結(jié)果 (1)PCoA變異和走形:缺如52.8%,發(fā)育不良8.9%、胚胎型17.1%、成人型21.2%。PCoA彎曲64.5%、平直35.5%。胚胎型更多呈平直,成人型更多呈彎曲(χ~2=7.5,P=0.006)。(2)PCoA直徑和發(fā)出角度男女、左右均未見統(tǒng)計學(xué)差異�？偲骄鵅A直徑與總平均PCoA直徑呈明顯負相關(guān),(r=-0.998,P=0.000)。(3)漏斗發(fā)生率為26%(32/121),漏斗組與非漏斗組間的PCoA變異(χ~2=10.2,P=0.001)、PCoA直徑(t=-5.7,P=0.000)及發(fā)出角度(t=-3.2,P=0.002)有統(tǒng)計學(xué)差異。結(jié)論 (1)PCoA直徑和BA直徑呈明顯負相關(guān)。(2)成人型、直徑更小、發(fā)出角度越小的PCoA越容易發(fā)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.
