Abstract
Retrograde catheterization of the right gastric artery was attempted in 22 patients for the purpose of proximal right gastric artery embolization. Retrograde catheterization was successfully performed in 12 of the 14 patients (86%) with smooth anastomoses. Retrograde catheterization was unsuccessful (n = 1) or time-consuming (n = 1) in two patients (14%) with smooth anastomoses. Right gastric artery embolization was successfully performed with microcoils in 13 of the patients. In all eight patients with tortuous anastomoses, catheterization was unsuccessful. Retrograde catheterization should be considered possible when preliminary angiography indicates a smooth anastomosis with the left gastric artery.
