摘要
目的:评价优化椎动脉造影显示基底动脉穿支血管的效果,以避免在神经介入术中损害相关后循环穿支动脉。方法:选取2017年3月-7月在我院行后循环全脑数字减影血管造影(DSA)检查的患者共80例,并随机分为对照组40例(常规椎动脉造影)和实验组40例(优化椎动脉造影)。造影后在不同模式下观测基底动脉以及双侧大脑后动脉,确定能否辨认穿支动脉,并统计两组每段穿支数目的不同。结果:两组造影后穿支动脉进行对比,发现实验组大脑后动脉P1段穿支动脉左、右侧分别为2.00±1.01和1.95±1.10支,对照组P1段左、右侧穿支动脉为1.52±0.71和1.45±0.81支;实验组P2段左、右侧穿支动脉为1.45±0.99和1.43±1.15支,对照组P2段左、右侧穿支动脉为0.78±0.65和0.55±0.55支;实验组基底动脉左、右侧脑桥穿支动脉为1.87±0.88和1.80±1.07支,对照组基底动脉左、右侧脑桥穿支动脉为0.37±0.54和0.28±0.50支;对照组观察所得各部位穿支动脉少于实验组,差异均有统计学意义(P<0.05)。结论:全脑数字血管造影中,经优化的椎动脉造影方法能够更有效地显示出后循环穿支动脉的数量,更好地观察穿支动脉走行,可以指导神经介入手术,防止术中损害相关穿支动脉。
Objective： To provide a better displayed method in order to avoid damaging the posterior circulation perforators in neurointervention surgery. Methods： Eighty patients in our hospital from March to July 2017 treated with posterior circulation cerebral brain DSA examination were randomly divided into control group （normal vertebral artery angiography, 40 eases） and experimental group （optimized vertebral artery angiography, 40 eases）. The basilar artery and proximal posterior cerebral artery on both sides were observed in different modes after angiography, and differences of the numbers of each segments perforators were counted in both groups. Results： To compare the two groups after angiography, we found that the average numbers of perforators in Pl segment were 2.00±1.01 and 1.95±1.10 on left and right sides in experimental group, vs. 1.52± 0.71 and 1.45±0.81 in control group; 1.45±0.99 and 1.43±1.15 vs. 0.78±0.65 and 0.55±0.55 in P2 segment; 1.87±0.88 and 1.80±1.07 vs. 0.37±0.54 and 0.28±0.50 in both sides of the pons perforators afterT of basilar artery. The number of perforators in each part of the control group was less than that of the experimental group, the differenee had statistical significance （P〈0.05）. Conclusions： The optimized vertebral artery angiography method can effectively show the numbers and direction of perforators of posterior circulation during the eneephalon angiography examination, which can guide neurointervention surgery and prevent to damage the related perforators in neurointervention.
