数字电影对急性消化道出血造影的动态研究

目的 动态研究数字电影血管造影在急性消化道出血的应用。方法 对５０例急性消化道出血者，采用数字式高速电影血管造影采像，动态观察动脉期，毛细血管期和静脉期。结果 全组５０例阳性发现４４例，胃十二指肠动脉出血１４例，胆道动脉出血２例，脾动脉出血３例，胃左动脉出血４例，胃网膜右动脉出血５例，肠系膜上动脉出血７例，肠系膜下动脉出血９例。１７例行永久栓塞，１１例行短期栓塞，９例经出血动脉内灌注止血剂。结论

Dynamic study on digital cineangiography of acute digestive tract hemorrhage

Objective To study dynamically acute gastrointestinal tract hemorrhage with digital cineangiography.Methods Fifty patients with acute gastrointestinal tract hemorrhage were performed with digital cineangiography and observed dynamically during arterial, capillary and venous phases. Results Among 50 cases, there were positive results in 44 ones including gastrointestinal hemorrhage in 14, biliary hemorrhage in 2, spleenic arterial bleeding in 3, left gastric arterial bleeding in 4, right gastrioepiploic arterial bleeding in 5, SMA bleeding in 7 and IMA bleeding in 9. 17 cases underwent a permanent embolization through artery and 11 with temporary embolization as well as 9 with infusion of hemostatic agent via artery.Conclusions Serial digital cineangiogram can dynamically show acute digestive tract hemorrhage within different phase. It is helpful to detect the location and cause of hemorrhage.
