The Arrow-Fischell pullback atherectomy catheter is designed to circumferentially debulk and retrieve coronary atheroma. We performed pullback atherectomy before balloon angioplasty or stenting in 41 patients. The device crossed the target lesion in 38 (93%) and obtained tissue in 36 (88%). All procedures were completed successfully and without myocardial infarction, emergency cardiac surgery, or death. Complications included major spasm in 8 patients, postprocedural abrupt closure in 1, and otherwise uncomplicated arterial perforation in 2. Pullback atherectomy can be performed relatively safely, but is more difficult than balloon angioplasty, obtains less tissue than directional atherectomy, and is associated with significant limitations.
Arrow-Fischell回撤式斑块旋切导管旨在沿圆周方向去除并回收冠状动脉粥样斑块。我们对41例患者在球囊血管成形术或支架置入术前进行了回撤式斑块旋切术。该装置在38例（93%）患者中穿过了靶病变，在36例（88%）患者中获取了组织。所有手术均成功完成，无一例发生心肌梗死、急诊心脏手术或死亡。并发症包括8例严重痉挛、1例术后急性闭塞以及2例无其他复杂情况的动脉穿孔。回撤式斑块旋切术可以相对安全地进行，但比球囊血管成形术更困难，获取的组织比定向斑块旋切术少，且存在明显局限性。
