| 目的 观察C臂CT支架精显技术用于植入颅内动脉支架的价值。方法 回顾性分析38例接受植入颅内动脉支架的症状性颅内动脉粥样硬化性狭窄患者,观察治疗中及治疗结束后即刻2D-数字减影血管造影(DSA)图中支架显影情况,并对目标动脉行超选择C臂CT扫描及支架精显重建。对比2D-DSA图与支架精显重建图显示支架结构主观评分,及支架显示清晰率及并发症检出率。结果 共对38例植入45枚支架。2D-DSA图主观评分为0分1枚、1分20枚、2分24枚;支架精显重建图示1枚主观评分为0、 44枚为3分,其支架显示清晰率为97.78%(44/45),高于2D-DSA图(0/45,P＜0.001)。2D-DSA所示44枚支架中,1枚支架张开不良、1枚见穿支血管异常。支架精显重建图示44枚中,2枚张开不良、2枚支架内血栓形成、2枚支架网丝突入血管腔内、3枚穿支血管痉挛并局限性狭窄。对8枚支架行球囊扩张致动脉夹层,之后重复植入支架,精显图示后续支架完全覆盖夹层破口。支架精显重建图并发症检出率高于2D-DSA图[38.64%(17/44) vs. 4.55%(2/44),P=0.002]。结论 C臂CT支架精显技术用于植入颅内动脉支架具有明显优势。 |

| Objective To observe the value of C-arm CT stent precision technology in intracranial arterial stent implantation. Methods Data of 38 patients with symptomatic intracranial atherosclerotic stenosis who underwent intracranial arterial stent implantation were retrospectively analyzed. Stent displayed in 2D-digital subtraction angiography (DSA) during and immediately after implantation were observed, and superselective C-arm CT scanning of target artery and stent precision reconstruction were performed. Subjective scoring of display stent structure in 2D-DSA and stent precision reconstruction images were comparatively analyzed, and the clarity rate of displaying stent and detection rate of related complications were compared. Results Totally 45 stents were implanted in 38 patients. In 2D-DSA, the subjective score was 0 of 1, 1 of 20 and 2 of 24 stents, respectively. Stent precision reconstruction image showed that subjective score was 0 of 1 stent and was 3 of 44 stents. The clarity rate of displaying stent in stent precision reconstruction image was 97.78% (44/45), much higher than that of 2D-DSA image (0 [0/45], P＜0.001). Among 44 stents displayed in 2D-DSA, poor stent opening and abnormal perforator vessel was observed in each 1 stent, and no clear abnormality was found in the rest stents. Among 44 stents revealed in stent precision reconstruction images, poor stent opening, thromboses in stent and stent mesh protruding into vascular lumen were found each in 2 stents, while perforator vessel spasm and localized stenosis after stent implantation were noticed in 3 stents. Arterial dissection occurred in 8 stents during balloon dilation, after timely implantation of a new stent, stent precision reconstruction images showed the dissection rupture was completely covered. The complications of stent precision reconstruction was higher than that of 2D-DSA (38.64% [17/44] vs. 4.55% [2/44], P=0.002). Conclusion C-arm CT stent precision technique had obvious advantages for intracranial artery stent implantation. |
