Three benefits of microcatheters for retrograde transvenous obliteration of gastric varices

Figure 1 Selective injection of the sclerosant. A: A microcatheter is navigated close to the gastric varices, and the sclerosant is selectively injected through the microcatheter (arrow); B: The gastric varices and gastrorenal shunt are fully filled with the sclerosant with contrast medium, and the afferent vein (arrow) is opacified; C: Contrast-enhanced computed tomography (CE-CT) before balloon-occluded retrograde transvenous obliteration (BRTO) shows gastric varices (asterisk); D: CE-CT one week after BRTO shows complete thrombosis of the varices (asterisk); E: Endoscopy before BRTO shows tumor-like varices (asterisk) in the fornix of the stomach; F: Endoscopy 3 mo after BRTO shows complete disappearance of the varices.
