First Versus Second Uterine Artery Embolization for Symptomatic Leiomyoma

摘要

OBJECTIVE. The purpose of this study was to compare the outcomes of second uterine artery embolization (UAE) with those of first UAE for symptomatic uterine leiomyoma. MATERIALS AND METHODS. In this single-institution retrospective study, between December 1997 and May 2016 first UAE was performed on 423 consecutively registered patients and second UAE on 11 consecutively registered patients to treat leiomyoma. The primary endpoint was infarction of all tumor tissue as seen at postprocedural contrast-enhanced MRI. The secondary endpoints were angiographic findings, embolization, MRI, and clinical outcomes 1 year after UAE. The outcomes were compared between the two groups. Multivariable linear regression analysis was performed to assess independent correlations with tumor infarction.
