The choice of embolic material was operator-dependent but included particles mixed with contrast (n=4), particles mixed with ethiodized oil
(n=2), particles mixed with contrast followed by microcoils (n=1), ethanol mixed with contrast followed by particles mixed with contrast (n=1), and microcoils alone (n=1).
Braun) mixed with ethiodized oil
(Lipiodol[R] Ultra-Fluid, Guerbet, France), and Onyx[R] 18 (Covidien, Mansfield, MA, USA).
With the needle in the portal vessels leading to the sites of hemorrhage, nonionic iodinated contrast was exchanged for N-butyl cyanoacrylate glue (TruFill, Cod-man and Shurtlef), which was diluted to a 1:2 ratio with ethiodized oil
This procedure consists of intraarterial administration of chemotherapeutic agent as well as ethiodized oil
, and the degree of uptake of ethiodized oil
after TACE is thought to represent tumor necrosis and imply the patient's prognosis (1,2).
Consequently, they are combined as a two-component embolic agent with either tantalum powder or ethiodized oil
. The added agent prolongs polymerization time, opacifes the liquid agent, and allows for its visualization under fuoroscopy.
