Liquid embolization of the gastroduodenal artery before selective internal radiotherapy (SIRT)

Abstract

Selective internal radiotherapy (SIRT) is a valuable technique in the palliative treatment of primary and secondary liver tumours. Before yttrium-90 microsphere embolization of hepatic tumours, the gastroduodenal artery (GDA) has to be embolized to prevent the migration of microspheres and the subsequent formation of non-healing ulcers of the upper gastrointestinal tract. A meticulous angiographic technique is required to prevent complications during SIRT as emphasized in best practice guidelines.
