title: Transportal intravariceal sclerotherapy with N-butyl-2-cyanoacrylate for gastric varices.
abstract: Four patients with gastric varices without catheterizable draining veins through a systemic vein were treated with transportal intravariceal sclerotherapy with n-butyl-2-cyanoacrylate (NBCA). In all patients, the gastric varices were successfully obliterated with 2-5 mL of NBCA-lipiodol mixture injected via a microcatheter introduced into the varices with transhepatic or transileocolic portal venous access. No complications related to the procedure were encountered. Follow-up gastroendoscopy showed disappearance (n = 3) or marked decrease (n = 1) of the varices. Neither recurrent gastric varices nor variceal bleeding were observed during the follow-up period (6-46 months). Transportal intravariceal sclerotherapy is useful for obliteration of gastric varices in selected cases.
