摘要
目的：通过对不同类型脑动静脉畸形（AVMB）造影技术的总结，分析AVMB的诊断及栓塞过程中选择性造影和微量造影应注意的技术问题。方法：人为地将50例AVMB分成两种类型，即高流低阻型（A）和高流高阻型（B）。根据不同的类型，设定不同的造影条件。栓塞过程中微量造影时。根据微导管的类型及微导管位于畸形团内的深度，定微量造影条件。结果：当微导管位于畸形团内时，压力应相应减低至120-150PSI，当微导管在供血动脉行经较长时，应重复造影，获得较为清晰的图像。结论：良好的造影条件能提供重要的影像信息，特别是微量造影，有时可能出现全和无的信息反差。
Objective： To analyze the technical problem of selective and superseleetive angiogram in the diagnosis and treatment of artefiovenous malformation of brain（AVMB）, Methods： 50 eases with AVMB diagnosed by digital subtraction angiography（DSA）, were divided into two groups： high flow and low resistance group （model A） and high flow and high resistance group （model B）. The conditions of angiogram were different according to different models. Parameters were set up in the superselective angiogram according to the model of microcatheter and the location inside AVMB nidus during embolization procedure. Results： If the head of microcatheter was inside the AVMB nidus, the pressure should be decreased to 120 - 150 PSI, Repeated angiogram was necessary to get a clear picture if there was a long road inside supplying vessel. Conclusion： Ideal parameter setting should be helpful for providing important image information, especially for superselective angiography . The parameter setting might mean best or worst sometimes,
