Purpose: To identify the incidence and outcomes of iatrogenic celiac and hepatic artery dissections during transarterial therapies, including bland embolization, chemoembolization, radioembolization (TARE), and pre-TARE scintigraphic mapping. Methods: The institution’s quality assessment database, electronic medical record, and picture archiving and communication system were reviewed to identify all patients who underwent transarterial locoregional therapy from 1/2001 to 7/2017 and to determine the incidence of iatrogenic dissection, to assess patency of the arteries after dissection, and to assess the ability to complete therapy. Results: 2253 patients underwent 3776 transarterial hepatic oncology procedures. Among 3776 procedures, 40 (1.1%) were associated with dissection of the visceral vasculature, affecting 39 patients (1.7%). The incidence of flow-limiting dissections was 0.3% (13/3776) and non-flow-limiting dissections was 0.7% (27/3776). After dissection, 68% (27/40) of treatments were completed the same day. Among the 13 aborted treatments, 8 (62%) were completed on a subsequent encounter. Follow-up imaging was obtained in 26 of 40 cases at median time of 63 days. Complete resolution of the dissection was seen in 15/26 cases (58%), near complete resolution (< 30% luminal narrowing) in 3/26 (12%), unchanged appearance of a non-flow-limiting dissection in 4/26 (15%), progressive luminal narrowing in 3/26 (12%), and complete occlusion in 1/26 (4%). Conclusion: Iatrogenic dissections of visceral arteries rarely occur during tumor embolization procedures. 35/39 (90%) of patients underwent successful treatment despite the dissection.
