Right gastric artery embolization prior to treatment with yttrium-90 microspheres / Sergio Álvarez Vallejo  

Público ISBD Título : Right gastric artery embolization prior to treatment with yttrium-90 microspheres Tipo de documento : documento electrónico Autores : Sergio Álvarez Vallejo, Fecha de publicación : 2007 Títulos uniformes : CardioVascular and Interventional Radiology Idioma : Inglés (eng) Palabras clave : Embolization  Right gastric artery  Yttrium90 Resumen : Purpose: Intra-arterial infusion of yttrium-90 microspheres is a form of radiation treatment for unresectable hepatic neoplasms. Misdeposition of particles in the gastroduodenal area such as the right gastric artery (RGA) may occur with serious consequences. We present a series of patients who underwent a detailed vascular study followed by RGA embolization. Special emphasis is placed on anatomic variations and technical considerations. Methods: In a 1 year period, 27 patients were treated. Initial vascular evaluation was performed, with careful attention to anatomic variants or extrahepatic arterial supply, especially to the gastroduodenal area. Embolization of such arteries was planned if needed. RGA embolization was performed antegradely from the hepatic artery or retrogradely via the left gastric artery (LGA). Postprocedural follow-up included clinical interview and gastroscopy if necessary. Results: RGA embolization was performed in 9 patients presenting with primary (n = 3) or metastatic liver tumors (n = 6). Six patients underwent antegrade RGA embolization and 3 had embolization done retrogradely via the LGA. Retrograde access was chosen for anatomic reasons. None of the patients complained of gastroduodenal symptoms. Conclusion: RGA embolization can help minimize the gastroduodenal deposition of radioactive particles. RGA embolization should routinely be carried out. The procedure can be performed, with similar technical success, by both anterograde and retrograde approaches.
