选择性腹腔动脉及肠系膜上动脉造影有相当一部分胰动脉及门脉影像显示不佳。为补充这一不足,作者在选择性血管造影过程中应用了血管收缩剂与扩张剂。这种药物性血管造影方法简单,胰动脉90%、门脉95%影像显示良好。普通选择性腹腔动脉造影方法:用注射器以10毫升/秒的速度注入造影剂40毫升,连续摄影。每秒2张拍6张。每秒1张拍3张。再每2秒1张拍6张。总计18秒、15张。以此能够显示胰血管的形态和血管的改变。
Selective celiac artery and superior mesenteric artery angiography have a considerable part of the pancreatic and portal venous images show poor. To supplement this deficiency, the authors used vasoconstrictors and dilators in selective angiography. This method of drug angiography is simple, 90% of the pancreatic artery, 95% of the portal vein images showed good. Ordinary selective celiac angiography method: with a syringe to inject 10 ml / sec contrast medium 40 ml, continuous photography. 6 second shots per second. 3 shots per second. And then every 2 seconds 1 sheet 6. A total of 18 seconds, 15. In order to be able to display the morphology of pancreatic vessels and vascular changes.
