Incidence and Consequence of Nontarget Embolization Following Bland Hepatic Arterial Embolization.

Purpose: Estimate the incidence of nontarget embolization (NTE) as identified on immediate post-hepatic artery embolization CT.

Materials And Methods: Two hundred hepatic embolizations performed with particles alone (bland embolization) in 147 patients between August 16, 2013 and August 26, 2014 with immediate post-procedure CT were retrospectively reviewed. Arterial anatomy, vessels treated, imaging findings of NTE, patient demographics, length of hospital stay following embolization, and procedure-related complications were recorded.
