Distal embolization occurred in 14 of 339 (4%) attempted percutaneous transluminal angioplasty (PTA) procedures, including five of 225 stenoses (2.2%) and nine of the 81 occlusions (11%) that were crossed successfully in 114 attempts (8%). Transcatheter embolectomy by aspiration through a nontapered large-bore catheter was technically successful in five of six attempts (83%), and was combined with successful PTA in three of five patients. In two patients in whom the clinical result of PTA was considered unsatisfactory, successful transcatheter embolectomy permitted an uncomplicated surgical by-pass procedure to be performed. If clinically significant embolization occurs during PTA, this procedure can be attempted prior to surgical embolectomy as an alternative to local fibrinolytic therapy.
在339例经皮腔内血管成形术(PTA)尝试中,有14例(4%)发生远端栓塞,包括225例狭窄中的5例(2.2%)和81例闭塞病变中的9例(11%),在114次尝试中有8%成功通过病变。通过非锥形大口径导管进行抽吸的经导管取栓术在6次尝试中有5次技术成功(83%),并且在5例患者中有3例与成功的PTA联合应用。在2例PTA临床效果不满意的患者中,成功的经导管取栓术使得能够顺利进行外科旁路手术。如果在PTA期间发生具有临床意义的栓塞,可在外科取栓术前尝试该操作,作为局部纤溶治疗的替代方法。
