International Circulation: Will you please talk about proximal protection for carotid stenting.
国际循环：请您谈谈颈动脉支架置入术的近端保护。

Prof. Gary M. Ansel:  Proximal protection is somewhat of a much newer protection device that allows us to do two things.  Firstly， it allows us to use our typical equipment that we would use， including a wire of our choice but it also allows us to cross the blockage after we are protection the patient.  So what this entails is putting a little balloon up into the external carotid， a catheter into the common carotid with a balloon around it， and inflates both of those balloons which actually either reverses flow or shuts down flow in just that internal carotid area.  Then we do the procedure and actually aspirate out any of the debris.  We are just now seeing the results from the EMPIRE trial which is very promising.  In about a month at VIVA we will be showing the ARMOR trial which will be release at that time too.
Prof. Gary M. Ansel: 近端保护在某种程度上是比较新的保护装置，使我们能够做两件事。首先，在保护病人的情况下我们可以根据需要选择带有导丝的装置，而且还可以穿越堵塞部位进行操作。我们需要将一个小气囊置于颈外动脉，将带有球囊的导管置于颈总动脉，通过球囊的膨胀使颈外动脉区域的血液返流或阻断血流。然后我们进行相关操作，准确地抽吸出血栓碎片。我们现在期待很有前景的EMPIRE试验结果。另外，大约1个月后，在VIVA我们将看到ARMOR试验的相关结果。
