Radioembolization complicated by nontarget embolization to the falciform artery.

The most common application of radioembolization is in the treatment of primary and secondary liver tumors, and the most common radioisotope is Yttrium-90. This form of treatment has proven to be successful in achieving reduction of tumor size and ultimately improving survival. Fatigue and nausea/vomiting are the most common side effects related to radioembolization and are usually self-limiting. This report describes a case of abdominal pain caused by shunting of yttrium-90 microspheres to the anterior abdominal wall via a patent hepatic falciform artery. This case highlights the need for vigilant angiography and awareness of the falciform artery with prophylactic embolization when necessary/warranted.
