Selective coronary angiography in severely dilated ascending aorta is technically challenging and sometimes impossible. The Terumo "five-in-six" system uses an extra long 5Fr guide catheter in a standard 6Fr guide catheter, so that the tip of the 5Fr guide catheter protrudes beyond the tip of the 6Fr catheter allowing an extra reach. This system has been used successfully to advance balloon catheters across chronic total occlusions (Takahashi et al, Catheter Cardiovasc Interv 2004;63:452-456) and stent delivery beyond proximal obstruction point (Mamas et al, Catheter Cardiovasc Interv 2008;71:358-363). We describe the successful use of this system in an atraumatic manner for selective coronary angiography in a patient with a severely dilated ascending aorta.
在严重扩张的升主动脉中进行选择性冠状动脉造影具有一定的技术挑战性，有时甚至无法进行。Terumo 的“五入六出”系统在标准的 6Fr 引导导管中使用了超长的 5Fr 引导导管，使得 5Fr 引导导管的尖端突出超过 6Fr 导管的尖端，从而增加了可触及的距离。该系统已成功用于推进球囊导管穿过慢性完全闭塞（Takahashi 等人，Catheter Cardiovasc Interv 2004;63:452-456）和支架输送到近端阻塞点（Mamas 等人，Catheter Cardiovasc Interv 2008;71:358-363）。我们描述了以一种无创伤的方式成功地在一名患有严重扩张升主动脉的患者中使用该系统进行选择性冠状动脉造影。
