Correlation of two different HydroCoil configurations in a patient prepared for a selective internal radioembolization procedure. The filament-like HydroCoil configuration (a) allows access to narrow vessels, such as the right gastric artery, in a retrograde fashion (arrowheads) using the expandable capabilities of the HydroCoil to induce vascular occlusion. After preparation at 55–70 °C (b), the compact configuration of a curled HydroCoil is useful for the proximal occlusion of the gastroduodenal artery (arrows) to avoid particle reflux during the radioembolization procedure
