The low-speed rotational transluminal angioplasty catheter system (ROTACS) is a recently available device for recanalization of occlusions prior to balloon angioplasty. The presence of large collaterals originating just proximal to the occlusion with an acute angle, and insufficient space between the puncture site and the occlusion for placing an introducer sheath are reported to be limitations for ROTACS. To avoid the rotating catheter entering the collateral, we propose a technique to create a pilot inlet on the proximal aspect of the occlusion. This technique was applied successfully in 4 patients. A contralateral approach was used in 3 patients, in whom an ipsilateral access was not possible because of the insufficient space to place an introducer sheath.
低速旋转腔内血管成形术导管系统（ROTACS）是一种最近可用的用于在球囊血管成形术之前使闭塞再通的设备。据报道，在闭塞近端以锐角发出的大侧支的存在，以及穿刺部位与闭塞之间没有足够空间放置导入鞘是ROTACS的局限性。为避免旋转导管进入侧支，我们提出了一种在闭塞近端创建引导入口的技术。该技术在4例患者中成功应用。3例患者采用了对侧入路，这些患者因没有足够空间放置导入鞘而无法采用同侧入路。
