Percutaneous transvenous obliteration for duodenal variceal bleeding using micro-balloon catheter and n-butyl cyanoacrylate: A case report

Owing to heavy blood flow originating from the portal vein and the technical difficulties associated with hemostatic procedures, duodenal varix is associated with high mortality and a poor prognosis. Percutaneous transvenous obliteration (PTO) has been used effectively to treat duodenal varices by providing direct control of duodenal variceal bleeding. This report describes a patient who experienced duodenal variceal bleeding that was successfully managed by PTO using a micro-balloon catheter, which can occlude the proximal afferent vein of the duodenal varix. Moreover, this technique can offer a more effective injection of n-butyl cyanoacrylate by blocking the inflow and preventing any reflux associated with duodenal variceal bleeding.Copyright (c) 2023, Society of Gastrointestinal Intervention.
