Abstract
Distal embolization occurred in 14 of 339 (4%) attempted percutaneous transluminal angioplasty (PTA) procedures, including 5 of 225 stenoses (2.2%) and 9 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 5 of 6 attempts (83%) and was combined with successful PTA in 3 of 5 patients. In 2 patients in whom the clinical result of PTA was considered unsatisfactory successful transcatheter embolectomy permitted an uncomplicated surgical bypass 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.
