Summary
Brief summary (as posted)
It is postulated that all arterial tumor feeders supplying a HCC tumor are interconnected with each other through the tumor sinusoid, such that when one of the feeders is catheterized for delivery of a liquid embolic agent, the whole tumor sinusoid will be embolized, if the arterial blood flow in all the other feeders are stopped temporarily to create a negative pressure gradient.

- Selective catheterization of segmental or more peripheral arteries in TACE
- description
- From the digital subtraction angiography (DSA), the number of arterial tumor feeders to the HCC is identified. One or more feeder(s) is to be catheterized for delivery of therapeutic agent using a 2.4 French microcatheter (Merit Maestro, Merit Medical Systems, Utah, USA), and the other feeder(s) is occluded with a balloon catheter using 0.1 to 0.2mL diluted contrast for inflation (4mm x 10mm Temporary Occlusion Balloon Catheter, Occlusafe, Terumo Clinial Supply, Gifu, Japan). The occlusion target could be a feeder or a common trunk leading to a number of feeders.
