Background: There are no reports analyzing imaging findings of arteries embolized with N-butyl cyanoacrylate (NBCA)-Lipiodol. To evaluate the time course of changes in the imaging findings of small arteries embolized with NBCA-Lipiodol. Materials and Methods: Selective transcatheter arterial embolization procedures via the inferior phrenic artery (right IPA, n = 25
left IPA, n = 5) were performed in 30 patients (25 males, 5 females
mean age 63 years, range: 45-78) at our institution. The NBCA-Lipiodol mixture was used as an embolic agent. The ratio of NBCA to Lipiodol was 1:4 (Group-A, n = 16) or 1:8 (Group-B, n = 14).We retrospectively reviewed the computed tomography (CT) findings and outcomes of small arteries embolized with the NBCA-Lipiodol mixture. The residual lipiodol was compared between Group-A and Group-B. The Student's t-test and Chi-square test were used for statistical analyses. In addition, the residual lipiodol rate was calculated using the Kaplan-Meier method and compared using the log-rank test. Results: The mean observation period was 264 ± 84 days (range: 104-425). Lipiodol completely disappeared in 20 arteries (66%) during follow-up. Recanalization of arterial flow was not seen in CT images, even when Lipiodol disappeared. Group-B showed a shorter period of progression to disappearance of Lipiodol than Group-A (P <
0.05). On follow up, the rate of residual Lipiodol in Group-A was higher than that in Group-B (P <
0.05). Conclusion: Residual Lipiodol was expected to gradually disappear. Lipiodol disappeared early when the density of NBCA was low in the NBCA-Lipiodol mixture. Further evaluations of various arteries and ratios of NBCA to Lipiodol are needed.
