Celiac Artery Stenting to Facilitate Hepatic Yttrium-90 Radioembolization Therapy
Treatment phase right hepatic angiogram images (a, b) demonstrate celiac artery stenting (6 × 15 mm Cordis chromium balloon expandable stent, white arrows) resulting in widely patent celiac axis with accessibility to the hepatic arteries. Coil embolization of gastroduodenal artery (two 10 mm × 10 cm tornado coils and two 8 mm × 4 cm coils, black arrows) prevents abnormal extrahepatic distribution. Additionally, a small accessory right hepatic branch was also coil embolized (two 3 × 2 mm platinum coils, white line arrows on (b)) to allow safer dose delivery and probable intrahepatic vascular flow redistribution [1, 2]. 90Y microspheres were injected within the right hepatic artery till end point without any immediate complications.
