Abstract

Yttrium-90 radioembolization is an effective treatment for liver cancers. However, deposition of radioactive microspheres in nondiseased liver can result in parenchymal injury. Segmental and subsegmental radioembolization may reduce off-target liver damage but may not always be possible due to anatomy. In this case report, we highlight the use of a microvascular plug (MVP) to protect distal nondiseased liver and redirect flow into the proximal tumor-containing liver volume during radioembolization of a gallbladder cancer recurrence. Throughout the report, we describe the technique, advantages, and limitations of using MVP-assisted temporary vascular occlusion during organ protection.

Keywords
