The use of certain large-caliber (ie, 7F to 9F) coronary guiding catheters for selected neuroendovascular procedures is described in the context of surveying recently developed neurovascular guiding catheters. These large-caliber guiding catheters have proved useful in situations requiring proximal access to tortuous brachiocephalic arteries, permitting coaxial delivery of relatively large neurointerventional devices, such as most detachable balloons and 5F percutaneous transluminal angioplasty catheters. These large-caliber coronary guiding catheters have some important advantages over both old and new neurovascular guiding catheters, including favorably preshaped configurations and superior torque control. These features permit relatively easy direct selective catheterization of unfavorable vascular anatomy resulting from dolichoectasia of the aortic arch and great vessels.
在调研最近开发的神经血管引导导管的背景下，介绍了某些大口径（即7F至9F）冠状动脉引导导管在特定神经血管内介入手术中的应用。这些大口径引导导管已被证明在需要近端进入迂曲的头臂动脉的情况下很有用，能够同轴输送相对较大的神经介入装置，如大多数可脱性球囊和5F经皮腔内血管成形术导管。与新旧神经血管引导导管相比，这些大口径冠状动脉引导导管具有一些重要优势，包括良好的预塑形构型和出色的扭矩控制。这些特性使得在主动脉弓和大血管迂曲扩张导致血管解剖结构不利的情况下，相对容易地进行直接选择性插管。
