目的 :探讨数字电影血管造影对急性消化道出血的价值。方法 :2 6例 ,年龄 7～ 85岁 ,平均 43 .3 6岁 ,均因急性消化道出血而行急诊腹部内脏血管造影 ,采集动脉期、实质期和静脉期影像 ,对图像作一回顾性分析。结果 :2 6例中阳性 2 2例 ,正常 4例 ,11例行血管内栓塞 ,3例经血管注入止血剂。动脉瘤 4例 ,肿瘤 3例 ,痔出血 2例 ,血管畸形 5例 ,原因不明造影剂外溢 12例。结论 :数字电影血管造影能快速实时成像 ,采像时间长、频率高 ,可动态观察 ,提高诊断准确性 ;数字成像能进行各种图像后处理 ,图像质量稳定而优良 ;可实现数据共享 ,且X线剂量低 Objective: To investigate the value of digital cine angiography in acute gastrointestinal bleeding. Methods: Twenty-six patients aged 7-85 years (mean 43.36 years) underwent emergency abdominal visceral angiography due to acute gastrointestinal bleeding. The images of the arterial phase, the parenchymal phase and the venous phase were collected and the images were retrospectively reviewed analysis. Results: In 26 cases, 22 cases were positive, 4 cases were normal, 11 cases were endovascular embolization, and 3 cases were transvascular injection of hemostatic agent. 4 cases of aneurysm, 3 cases of tumor, 2 cases of hemorrhoids and 5 cases of vascular malformation. There were 12 unexplained contrast media for unexplained aneurysm. Conclusions: Digital cine angiography can rapidly and real-time imaging, take a long time, high frequency, can be dynamically observed to improve diagnostic accuracy; digital imaging can be a variety of image post-processing, image quality is stable and excellent; data sharing can be achieved, and X-ray dose is low
