Endoscopic varicealography (or varicography) during endoscopic injection sclerotherapy is a retrograde venography as described in Chap. 23 “Takase method” of endoscopic injection sclerotherapy for esophagogastric varices. Excessive injection of 5% ethanolamine oleate with iopamidol (5%EOI) causes portal thrombosis, renal dysfunction, or lung congestion. The flow of the sclerosant is monitored by varicealography. The amount of 5% EOI can be controlled either by visualizing the filling of supply route or visualizing paraesophageal, inferior phrenic, or mediastinal veins.
